They鈥檙e at the forefront of leading-edge research fields, from sorting through the overwhelming mass of words in our lives to developing electronics that can bend their shape.
Today, two of Dal鈥檚 newest faculty members 鈥� Stan Matwin of the Faculty of Computer Science and Greg Welch of the Department of Chemistry 鈥� were awarded new Canada Research Chairs by the Government of Canada. A third 新加坡六合彩开奖直播 researcher, James Drummond of the Department of Physics and Atmospheric Science, had his Canada Research Chair renewed.
The announcement was made this morning at Western University by the Honourable Gary Goodyear, Minister of State (Science and Technology). It included $90.6 million in support to 120 new and renewed Canada Research Chairs across the country.
Sorting through a world of words
The digital age has put more words at our fingertips than at any point in human history. And Stan Matwin, who joined Dal鈥檚 Faculty of Computer Science this January, is developing tools to help manage it all.
As the Tier I Canada Research Chair in Visual Text Analytics, his team will develop machine learning methods that extract interesting and useful knowledge from huge blocks of text 鈥� databases, document collections, social media 鈥� organizing it so it can be applied to solve real problems.
鈥淵ou鈥檝e heard the term 鈥榖ig data鈥�; well, this is part of that, but it鈥檚 鈥榖ig text鈥� in particular,鈥� he explains.
At the University of Ottawa, Dr. Matwin led text analytics projects in a wide variety of fields: helping medical researchers more efficiently find relevant abstracts in databases of hundreds of thousands of documents, analyzing the sentiment of tweets during presidential elections, even helping psychologists find patterns in dream recordings.
鈥淲hat鈥檚 interesting to me is fusing data related to the same subject,鈥� he explains. 鈥淢edicine is a great example: you may have some data that鈥檚 mostly numbers, but then you have doctors' or nurses' notes in text, as well as images and external collections of knowledge from the field. The exciting thing is to put them together, get the data to talk with one another.鈥�
Though he just arrived on campus, Dr. Matwin already has several major grant proposals well underway. He鈥檚 completing a study on Twitter sentiment during the 2012 French presidential election, and is also excited to connect his work with Halifax鈥檚 medical and IT communities. He says he鈥檚 most eager for the opportunity to bring his expertise to Halifax and 新加坡六合彩开奖直播鈥檚 booming ocean sciences sector.
鈥淚鈥檓 looking forward to connecting these types of problems [that I explore] with researchers doing work with oceans data. They have big data sets, and I鈥檓 meeting with them as we speak at how we can do something together, so we can build a world-class centre for big marine data in Halifax.鈥�
Printed electronics: just around the bend
新加坡六合彩开奖直播鈥檚 second new Canada Research Chair announced today is Greg Welch of the Department of Chemistry. He becomes the Tier II Canada Research Chair in Organic Functional Materials, focused on developing organic chemical materials that can be used to create lightweight, flexible components for electronic devices: imagine solar panels that could be unrolled like paper, or phone or television screens that would bend and change shape.

鈥淎s soon as you replace inorganic components with organic, you open this whole new world of solution processing which allows us to fabricate these devices onto lightweight, flexible substrates,鈥� says Dr. Welch. 鈥淵ou can bend, stretch and manipulate them in all sorts of new ways.鈥�
Dr. Welch, who came to Dal last year after completing his postdoctoral work at the University of California at Santa Barbara, is creating an advanced organic materials laboratory in the Department of Chemistry. There, his team will make next-generation organics that can effectively and efficiently absorb and emit light, or transport a charge, or complete other processes depending on what sort of device they鈥檙e designed for.
His work, by nature, requires partnerships with physicists and materials scientists to test and refocus these materials. And on that front, a lot of that collaboration will be done right here at Dal: Dr. Welch has already struck a strong working relationship with Professor Ian Hill of the Department of Physics and Atmospheric Science, whose lab studies precisely the sort of organic thin film transistors and solar cells that these materials are designed for.
鈥溞录悠铝喜士敝辈� is a very unique university because it鈥檚 small, so the faculty can easily communicate,鈥� he says. 鈥淚t鈥檚 a very open, collaborative environment, so it allows for very rapid sharing of ideas, and everyone is here to work together. And there鈥檚 a genuine interest on the part of students in new technologies out here. I think Nova Scotia is a very progressive province: it鈥檚 built on going a little different, and alternative energy is big out here.鈥�
As well, Dr. Welch says being able to do this work in Canada is important. (He says he鈥檚 鈥渦nashamedly patriotic,鈥� in that way.) With the organic electronics market set to become a billion-dollar industry in the next decade, he says Canada lags behind other countries in the field, but he鈥檚 eager to help the country鈥檚 industry catch up to and surpass its international competition.
鈥淲e want to contribute to Canadian society,鈥� he says. 鈥淲e want to generate IP here.鈥�
Global leaders
新加坡六合彩开奖直播 also had a Chair renewal in today鈥檚 announcement: James Drummond of the Department of Physics and Atmospheric Science was renewed as the Tier I Canada Research Chair in Remote Sounding of Atmospheres. He鈥檚 an international leader in space instrument design, testing and deployment, and his work uses satellites and ground-based observations to study the composition of the atmosphere. With new, specialized instruments, Drummond and his colleagues are collecting information that informs how best we can keep the air around us healthy.
The Canada Research Chairs program invests approximately $300 million each year toward research in engineering and the natural sciences, health sciences, humanities and social sciences.
新加坡六合彩开奖直播 has 53 Canada Research Chairs in total, more than any university in Atlantic Canada.
