Competition this year was tough, with close to 1,000 applicants, said Jon French, spokesperson for The Next 36.</p> <p>Those who are selected are given the opportunity to develop their business ideas and put them into action with help from Canadian business leaders, with mentorship and lectures from world-class faculty over a nine-month period. The entrepreneurship-immersion program also provides those selected with up to $95,000 in seed investment for new ventures.</p> <p>"I applied to The Next 36 because I wanted to make a positive impact in the world, and I believe entrepreneurship is one way to do so," said <a href="http://utsccommons.utsc.utoronto.ca/spring-2012/web-exclusives/uncertainty-leads-possibility"><strong>Mingyuan Li</strong></a>, a human biology major who graduated from University of Toronto Scarborough this year. "Entrepreneurship is an opportunity for me to bring my innovations to the world, and in so doing, I hope that it will improve the quality of life of others."</p> <p>Now researching cystic fibrosis at&nbsp;Toronto's Hospital for Sick Kids, Li will join teammates from&nbsp;Â鶹ֱ²¥app engineering and McGill University's commerce program to develop an app&nbsp;for parents of small children.</p> <p>"We would use existing devices such as smartphone or wearable technology to help them keep track of&nbsp;the whereabouts of the child," said Li. "Our app can also extend to ensure the safety of the elderly and those with neurodegenerative diseases – to ensure that they are always safe and at a location where they can be protected."</p> <p>Having so many Â鶹ֱ²¥app engineering students on this year's list is rewarding, said <strong>Joseph Orozco</strong>, executive director of entrepreneurship at the Entrepreneurship Hatchery and adjunct professor of the Centre for Management of Technology and Entrepreneurship.</p> <p>"Seeing 10 of our students among The Next 36 shows the message of innovation and an understanding of business is coming through," Orozco said, adding&nbsp;that one of The Next 36 students has applied to the Hatchery program, which offers similar services, and he hopes to see more.</p> <p>"I personally believe we all have an entrepreneurial seed inside of us. What we do here is allow that seed to flourish. It's not always about creating your own business but being able to work in any environment, any company. These students are going to be better members of society."</p> <p>Nine of those selected from Â鶹ֱ²¥app came from engineering’s enriched program of engineering science and&nbsp;five of&nbsp;the&nbsp;students are either enrolled in, or have completed engineering entrepreneurship courses.</p> <p>"There is a renewed emphasis on design and innovation in the Faculty of Applied Science and Engineering, and this is contributing to a culture of entrepreneurship in our students," said Professor&nbsp;<strong>Mark Kortschot</strong>, chair of engineering science and himself an experienced entrepreneur. "Needless to say, I am extremely pleased with the performance of our students in this year’s The Next 36 competition and confident that they will make the most of this outstanding opportunity,"&nbsp;</p> <p><img alt src="/sites/default/files/thenext36-james-tim-13-12-11.jpg" style="margin: 10px 30px; width: 600px; height: 400px">Engineering's <strong>Timothy Ahong</strong> and <strong>James Schuback</strong>&nbsp;(pictured above) are on a team developing a wearable motion sensor which provides feedback on athletic technique and motion for a variety of sports. The device compares a person's motion, whether it's a tennis or golf swing, or other motions, to that of the pros. Now infected with the entrepreneurship bug, Ahong plans to take an engineering entrepreneurship course later.</p> <p>"The Next 36 is an amazing opportunity and I still can't believe I'm doing this," said Schuback. "Entrepreneurship is the path I've chosen after graduation, and I plan to pursue this or a related project."</p> <p>Â鶹ֱ²¥app alumni and students in The Next 36 will be building their startups along with their co-founders (small teams applied) and mentors. Other ideas presented by students included: a motorized blimp for filming events and a fashion consulting platform.&nbsp;</p> <p>Projects may change from the initial idea over the course of the program as Venture Day in mid-August 2014 gets closer. That's the program's annual Capstone Event where ventures are showcased to investors and business leaders from across North America. It is also when the students officially graduate from The Next 36 program.</p> <p>The Next 36 began as a way to address Canada's shortage of high-impact entrepreneurs. The organization provides a resource-rich program to a select group of promising undergraduates, and was founded by a small group of entrepreneurs, business leaders and academics, a number of whom are Â鶹ֱ²¥app engineering alumni.</p> <p>This year's roster of Â鶹ֱ²¥app participants also includes:&nbsp;<strong>Amir-Hossein Karimi</strong>; <strong>Shums Kassam</strong>; <strong>Vivek Kesarwani</strong>;<strong>&nbsp;</strong><strong>Drew MacNeil</strong>; <strong>Tejas Mehta</strong>;&nbsp;<strong>Jonathan Yam</strong>; <strong>Victor Zhang</strong> and <strong>Cheng Zhao</strong>.<br> <br> <em>Pippa Wysong is a writer with the Faculty of Applied Science &amp; Engineering.</em></p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> <div class="field field--name-field-picpath field--type-string field--label-above"> <div class="field__label">picpath</div> <div class="field__item">sites/default/files/the-next-36-li-mingyuan.jpg</div> </div> Thu, 12 Dec 2013 09:19:04 +0000 sgupta 5777 at Stem cells: how to predict their fate /news/stem-cells-how-predict-their-fate <span class="field field--name-title field--type-string field--label-hidden">Stem cells: how to predict their fate</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>sgupta</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2013-10-22T09:52:50-04:00" title="Tuesday, October 22, 2013 - 09:52" class="datetime">Tue, 10/22/2013 - 09:52</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Emanuel Nazareth is a PhD student working with Professor Peter Zandstra</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/pippa-wysong" hreflang="en">Pippa Wysong</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Pippa Wysong</div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/top-stories" hreflang="en">Top Stories</a></div> <div class="field__item"><a href="/news/tags/ibbme" hreflang="en">IBBME</a></div> <div class="field__item"><a href="/news/tags/engineering" hreflang="en">Engineering</a></div> <div class="field__item"><a href="/news/tags/research" hreflang="en">Research</a></div> </div> <div class="field field--name-field-subheadline field--type-string-long field--label-above"> <div class="field__label">Subheadline</div> <div class="field__item">Technique has potential for regenerative medicine and drug development</div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>University of Toronto researchers have developed a method that can rapidly screen human stem cells and better control what they will become - a&nbsp;technology that could&nbsp;be used for regenerative medicine and drug development.&nbsp;</p> <p>The findings are published in this week's issue of the journal <em>Nature Methods</em>.</p> <p>“The work allows for a better understanding of how to turn stem cells into clinically useful cell types more efficiently,†said&nbsp;<strong>Emanuel Nazareth</strong>, a PhD student at&nbsp;Â鶹ֱ²¥app's Institute of Biomaterials &amp; Biomedical Engineering (IBBME). The research comes out of the lab of Professor <strong>Peter Zandstra</strong>, Canada Research Chair in Bioengineering at Â鶹ֱ²¥app.</p> <p>The researchers used human pluripotent stem cells (hPSC), cells which have the potential to differentiate and eventually become any type of cell in the body. But the key to getting stem cells to grow into specific types of cells, such as skin cells or heart tissue, is to grow them in the right environment in culture, and there have been challenges in getting those environments (which vary for different types of stem cells) just right, Nazareth said.</p> <p>The researchers developed a high-throughput platform, which uses robotics and automation to test many compounds or drugs at once, with controllable environments to screen hPSCs in. With it, they can control the size of the stem cell colony, the density of cells, and other parameters in order to better study characteristics of the cells as they differentiate or turn into other cell types. Studies were done using stem cells in micro-environments optimized for screening and observing how they behaved when chemical changes were introduced .</p> <p>Researchers&nbsp;found that two specific proteins within stem cells, Oct4 and Sox2, can be used to track the four major early cell fate types that stem cells can turn into, allowing four screens to be performed at once.</p> <p>“One of the most frustrating challenges is that we have different research protocols for different cell types. But as it turns out, very often those protocols don’t work across many different cell lines,†Nazareth said.</p> <p>The work also provides a way to study differences across cell lines that can be used to predict certain genetic information, such as abnormal chromosomes. What’s more, these predictions can be done in a fraction of the time compared to other existing techniques, and for a substantially lower cost compared to other testing and screening methods.</p> <p>“We anticipate this technology will underpin new strategies to identify cell fate control molecules, or even drugs, for a number of different stem cell types,†Zandstra said.</p> <p>As a drug screening technology "it’s a dramatic improvement over its predecessors,†said Nazareth. He notes that in some cases, the new technology can drop testing time from up to a month to a mere two days.</p> <p>Professor Zandstra was awarded the 2013 Till &amp; McCulloch Award in recognition of this contribution to global stem cell research.</p> <p><em>Pippa Wysong is a writer with the Faculty of Applied Science &amp; Engineering</em></p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> <div class="field field--name-field-picpath field--type-string field--label-above"> <div class="field__label">picpath</div> <div class="field__item">sites/default/files/stem-cells-nazareth-13-10-22.jpg</div> </div> Tue, 22 Oct 2013 13:52:50 +0000 sgupta 5668 at Convocation 2013: five engineers to watch /news/convocation-2013-five-engineers-watch <span class="field field--name-title field--type-string field--label-hidden">Convocation 2013: five engineers to watch</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>sgupta</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2013-06-20T07:21:21-04:00" title="Thursday, June 20, 2013 - 07:21" class="datetime">Thu, 06/20/2013 - 07:21</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">More than 1,000 Â鶹ֱ²¥app Engineering students graduate every year (all photos by Roberta Baker)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/pippa-wysong" hreflang="en">Pippa Wysong</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Pippa Wysong</div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/features" hreflang="en">Features</a></div> <div class="field__item"><a href="/news/tags/students" hreflang="en">Students</a></div> <div class="field__item"><a href="/news/tags/engineering" hreflang="en">Engineering</a></div> <div class="field__item"><a href="/news/tags/convocation" hreflang="en">Convocation</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p><em>More than&nbsp;1,000 University of Toronto Engineering students graduate every year. Each one of them is exceptional, and each one has a story to tell. </em></p> <p><em>Writer <strong>Pippa Wysong</strong>&nbsp;talked to five of those students – <strong>Shailin Gosalia</strong>, <strong>Jocelyn Light</strong>, <strong>Catherine Phillips-Smith</strong>, <strong>Luis Ramirez</strong> and <strong>Sandra Sousa</strong> – about what roads led them to Â鶹ֱ²¥app Engineering, and what roads they will take in the future</em>.</p> <p>For <strong>Shailin Gosalia</strong> of Mechanical Engineering, being an engineering student at&nbsp;Â鶹ֱ²¥app&nbsp;wasn’t about doing just the coursework, it was also about community. When he started his studies in 2008, he had just moved to Canada and understood all too well what it was like being a newcomer.</p> <p>“While Toronto is an extremely multicultural city, I felt that having a strong network within the university setting would help students settle sooner,†he said. And so, three years ago, he became part of the then fledging Indian Students' Society (ISS).</p> <p>The goal of the ISS is to help students become integrated with the university culture, meet people, find ways to integrate Indian and Canadian cultures, and have fun.</p> <p><img alt src="/sites/default/files/engineers-shailin-resized.jpg" style="margin: 10px; width: 400px; float: left; height: 267px">“They can still continue to enjoy their old cultural values while learning to integrate into a new culture. I believe in appreciating one’s roots, but moving forward in the Canadian direction – one of multi-multiculturalism, tolerance and acceptance of everyone,†he said.</p> <p>The group is now 800 strong (he figures about 40 per cent are engineering students). It organizes events for Frosh Week, as well as a series of debates, shows and social gatherings throughout the year.</p> <p>Gosalia spent his final year at Â鶹ֱ²¥app Engineering as ISS president. He was also an active member of an intramurals soccer team over the past four years, and served as both a player and coach for Tri-Campus Cricket at the University.</p> <p>Not surprisingly, because of his involvement on campus, he was awarded the Gordon Cressy Student Leadership Award in recognition of his volunteer work with Â鶹ֱ²¥app Engineering. He also held a position at the Â鶹ֱ²¥app Telefund Centre, raising over $15,000 towards student scholarships and awards.</p> <p>Gosalia was driven towards engineering in part because he liked mathematics and physics, but also because he had a dream of learning skills that would let him help find solutions to some of the world’s pressing problems. Partway through first year he zeroed-in on health care.</p> <p>“I want to apply my engineering skills in the biomedical field to see how we can reduce the workload on healthcare workers, how we can incorporate technology into existing frameworks of the healthcare sector so we can reduce inefficiencies and improve overall care for patients.â€</p> <p><img alt src="/sites/default/files/engineers-jocelyn-resized.jpg" style="margin: 10px; width: 400px; float: left; height: 267px">As <strong>Jocelyn Light</strong>&nbsp;of Engineering Science&nbsp;found out, at Â鶹ֱ²¥app Engineering, learning engineering skills and what it takes to become an engineer doesn’t have to be done all in the classroom. Or even in Canada for that matter.</p> <p>With an underlying interest in social justice, and wanting to help people in desperate circumstances, she participated in programs that took her to different parts of Africa. Her activities led to her winning a Gordon Cressy Student Leadership Award.</p> <p>One year, she spent her summer months in Gambia, thanks to a summer placement with the Centre for Global Engineering. There, she was paired with Chemical Engineering&nbsp;PhD student Bev Bradley who was working on ways to make medical oxygen more accessible to people who live in resource-poor areas.</p> <p>One of Light’s projects was analyzing data on temperature and humidity and how it affected the lifespan of the rechargeable batteries used in portable oxygen concentrators – devices that extract and concentrate oxygen from the air. Batteries are important for various medical devices because power in Gambia is not stable, she said. She also worked on a project relating to the disposal and incineration of medical waste.</p> <p>Light spent her next summer in Malawi, this time with a team from Engineers Without Borders (EWB). In Malawi, her work was related more to agriculture and the challenges faced by small-time, independent farmers.</p> <p>She is keen on biomedical engineering, and her eventual goal is to be involved in projects that help people. Right now, she’s working in the EWB offices, helping to set policies, and matching people with specific talent and skills to parts of the world where it is needed.</p> <p>Her work with EWB is eye-opening, she said. It’s helping her decide “what it is that I want to be doing in the sense of what I want to be contributing to our society and our systems.â€</p> <p><img alt src="/sites/default/files/engineering-bees-resized.jpg" style="margin: 10px; width: 400px; float: left; height: 267px">What do bees, the ocean, horses, chemistry, skiing and stage work have in common? The answer is <strong>Catherine Phillips-Smith</strong> of Chemical Engineering.</p> <p>‘Variety’ is the best word to describe Phillips-Smith, whose interests include everything from being a part-time beekeeper to painting props for Skule Nite shows to participating in a summer student fellowship at Woods Hole Oceanographic Institution (WHOI). She even helped organize the Skule Arts Festival – an annual week-long festival showcasing Â鶹ֱ²¥app Engineering students’ artwork.</p> <p>When she first stepped onto the Â鶹ֱ²¥app campus, Phillips-Smith made a decision. “I figured that in four years there is so much you can do, and I’m just going to do as much as I can. University is what you make it, I tried to make it the best I could,†she said.</p> <p>But her varied interests were evident at a young age. She’s been riding horses regularly for the past 12 years. She decided to become a beekeeper in high school, after reading Susan Hubbard’s vampire novel The Society of S, which had a character who kept bees.</p> <p>At the end of her first year at Â鶹ֱ²¥app, she installed her first beehive on the farm where she goes riding. She now has eight hives, each producing up to 120 pounds of honey a year.</p> <p>Phillips-Smith also installed a hive on the roof of the Galbraith Building. “It’s an experiment in urban agriculture, run partly through the department and some grad students,†she said. During her time at Â鶹ֱ²¥app Engineering, she tended the hive, and led workshops on beekeeping.</p> <p>In the winter, she is a part-time ski instructor at Beaver Valley. And with an interest in nature and the environment, WHOI was a natural attraction. She spent three months there learning how to monitor and study ocean health by studying its colour – which indicates the amount of phytoplankton present.</p> <p>“I learned a lot about the huge role the ocean plays in everything and how we’re changing it. You wouldn’t think we could change such a big part of the world – the ocean is everywhere. But we are changing it, and the changes are getting pretty out of hand,†she said.</p> <p>Her passion for the environment has paid off academically. At Convocation this year, she was awarded the Mackay Hewer Memorial Prize, given to a Chemica Engineering student whose thesis/capstone design project is judged to be the best in the environmental category.</p> <p>And the future? Phillips-Smith hopes to continue to work and do research relating to the environment. Naturally.</p> <p><img alt src="/sites/default/files/engineering-duo-resized.jpg" style="margin: 10px; width: 450px; float: right; height: 300px">If ever two students reflected the spirit and energy of Â鶹ֱ²¥app Engineering, it's been <strong>Luis Ramirez</strong>&nbsp;and <strong>Sandra Sousa </strong>of Electrical Engineering.</p> <p>Not only were they involved in a myriad of student-based campus activities, but they motivated many other students to get involved as well.</p> <p>That motivation was most obvious when they co-chaired the Engineering Student Society’s Blue and Gold committee in the 2011-2012 school year. But before that, Sousa already had a history of being active in engineering activities. In her first year, she managed the Cannon Ball – an annual dinner/dance. The following year, she was named Godiva’s Crown, “something that is supposed to represent school spirit,†she said. Clearly, a sign of things to come.</p> <p>She was also involved with Skule Nite for four years, working both on and backstage, and occasionally was part of Engineering's Lady Godiva Memorial Bnad (sic). Skule Nite was a natural draw – when she was growing up, she leaned towards music and drama, though as she got older she appreciated the creativity in math and science, and found herself in engineering.</p> <p>Ramirez meandered his way towards engineering via an early love of playing video games. Both he and Sousa ended up in Electrical and Computer Engineering.</p> <p>While serving as B&amp;G chairs, a lot happened. They coordinated events and volunteers for Frosh Week, Godiva Week, and various clubs and parties – including bowling nights, and even a Game of Thrones Marathon. And they ran the engineering pub.</p> <p>Volunteers on the committee built floats for Frosh Week – one float in the style of a big castle for the Â鶹ֱ²¥appcoming Parade was big enough to support the entire Bnad.</p> <p>A particular highlight for Ramirez and Sousa was the building of a float for Toronto’s annual Pride Parade.</p> <p>“We wanted a float that would show our support for Pride and that our fellow students could identify with, so we chose to build a giant shiny version of Godiva's horse,†Ramirez said. It was the first year that Â鶹ֱ²¥app Engineers added a float to their normal Pride activities of simply marching in the parade. The float consisted of a big decked-out pick-up truck with a large horse sitting on top. The Bnad, along with other supporters, marched behind.</p> <p>It was such a hit that Pride Toronto presented Â鶹ֱ²¥app Engineering with the <a href="http://www.engineering.utoronto.ca/About/Engineering_in_the_News/Engineering_Students_Win_Pride_Parade_Award.htm" target="_blank">Special Judges Award for Shock and Awe</a>. The shock part of the award was undoubtedly earned when the engineers fired the Skule Cannon in front of the judges. “We tried to make an ‘Earth shattering kaboom’,†Ramirez joked.</p> <p>All these events are inspired by longstanding Â鶹ֱ²¥app Engineering traditions, Ramirez said.</p> <p>“We have this awesome community in engineering. So many people are involved, and there are so many different aspects to it. It gives all of us a great opportunity to come out of our shell and develop our talents,†he said.</p> <p>Aside from B&amp;G activities, and studying, Ramirez played and coached rugby. He also took a PEY elective where he worked for a company that develops mobile apps, and now has an interest in networking infrastructure.</p> <p>Sousa is now helping with project management for a big hospital renovation project. She enjoys working with people and sees herself continuing work that involves teams.</p> <p><em>Pippa Wysong is a writer with the Faculty of Applied Science &amp; Engineering at the University of Toronto.</em></p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> <div class="field field--name-field-picpath field--type-string field--label-above"> <div class="field__label">picpath</div> <div class="field__item">sites/default/files/overall-engineering.jpg</div> </div> Thu, 20 Jun 2013 11:21:21 +0000 sgupta 5452 at
