Christopher M. Collins

I am an associate professor and Canada Research Chair in Linguistic Information Visualization at the University of Ontario Institute of Technology (UOIT), where I lead a lab of 10 students at various levels of study. My research focus is interdisciplinary, combining information visualization and human-computer interaction with natural language processing to address the challenges of linguistic information management and the problems of information overload. My publications, including the DocuBurst document content visualization system, have helped to open a new and thriving area of research in “Linguistic Visualization”. My work has been published in many venues, including the IEEE InfoVis, IEEE VAST, ACM ITS, EuroVis, and IEEE Transactions on Visualization and Computer Graphics,  as well as featured in popular media such as the Toronto Star, New York Times Magazine, and CBC Radio.

I received my PhD in Computer Science from the University of Toronto in 2010. I have collaborated with the Innovis group at the University of Calgary, the Visual Communications Lab at IBM’s TJ Watson Research Laboratory and was recently a visiting researcher at Stanford University’s Department of Computer Science. I maintain fruitful research collaborations with exciting companies, including my work with Ontario-based Quillsoft Ltd. on their iWordQ reading assistance mobile application.

I hold several volunteer positions within the information visualization community, including on the organizing committee for the 2014-2017 IEEE Vis Conferences, and formerly as part of the IEEE Visualization and Graphics Technical Committee Executive.

Interested in studying with me?

I am actively building the vialab research group at UOIT − if you are passionate about HCI and Information Visualization, and you are seeking a great place for graduate studies in computer science, please contact me.  I receive many requests to join the lab. To make sure you stand out, please consider including in your first message a description of why you want to study with me – what is it about the research at the vialab that interests you? What relevant skills and experience do you bring?

Rafael Veras

Graduate Student

I’m currently pursuing my Doctoral degree in Computer Science. In my Master’s thesis work, I used NLP techniques to train the first empirical semantic model of passwords and demonstrated the model can be used to guess more passwords than the current approaches. I’m primarily interested in information visualization and human-computer interaction, in general. Other topics of interest include natural language processing and natural user interfaces.

I got my Bachelor’s degree from Federal University of Pará, in Belém, the main city of the Brazilian Amazon region. While in my undergraduate program, I worked in several InfoVis projects and published a few papers. I also worked in a small software company as a programmer before starting my Master’s.

Currently, I am working on this project, whose goal is to find a better method for generating overviews of arbitrary hierarchical datasets. Its preliminary results were presented as a poster at Vis 2014. To some extent, this project fits into the theme of analytical guidance in visualization, which I am excited about.

Adam Bradley

Adam Bradley, BA (McMaster) MA (Waterloo), holds a PhD in English Language and Literature and Systems Design Engineering from the University of Waterloo and is currently a Research Associate in the Vialab. Adam’s overall work is concerned with the intersections between technology and traditional literary studies with a focus on early 20th century poetics. His MA research project, titled “Data Visualization and the Avant-Garde Aesthetic” was a digital humanities project completed in conjunction with the English department’s Critical Media Lab and the Engineering department’s Touchlab. His project investigated whether shifting the aesthetics of a given text can offer new insights into the study of its structure and how the integrity of that text can be maintained within this paradigm. His current work focuses on digital tool design for literary criticism and language visualization.

Mariana Shimabukuro

Graduate Student

I am a PhD student in Computer Science, and my current project relates to educational applications.

I got my Masters of Science degree from the Computer Science program supervised  by Dr. Christopher Collins at University  of Ontario Institute of Technology in 2017. My Masters project is titled as “An Adaptive Crowdsourced Investigation of Word Abbreviation Techniques for Text Visualizations” where I collected data on how people create abbreviations allowing me to design an abbreviation algorithm.

I have some experience in the industry where I worked with natural language processing (NLP) regarding extraction of named entity recognition (NER) in the context of law cases corpora in portuguese.

I have also worked with educational technologies applied to introducing programming techniques using robotics. During my undergraduate studies, I joined a group called GISDI, which develops applications for mobile robotics in an educational environment. This environment is taken to schools where programming lessons are given.

While still in university for my undergraduate degree, I was granted a scholarship by the Brazilian government,  named Science Without Borders. Through this scholarship, I was able to spend my third year of undergraduate studies in Canada at the University of Ontario Institute of Technology – UOIT. As an exchange student, I attained a summer position at vialab and started working on my word abbreviation studies.

In 2015, I graduated from the University of State of Sao Paulo – UNESP in Brazil  as top of my class in 2015 with a Bachelor’s degree in Computer Science.

In my spare time, I like going to the gym; lifting weights, building muscle and doing some HIIT cardio. Well, I try to be as fit as I can. Once I am a food lover, I work out hard so I can eat more.

Hrim Mehta

Graduate Student

I am a PhD candidate in Computer Science at UOIT, co-supervised by Dr. Christopher Collins and Dr. Fanny Chevalier. My main interest lies in mixed-initiative visual analytics. I’m currently developing a framework to formalize and guide the design of semi-automated narratives or tours to prompt and sustain the process of data exploration.

I received my Master’s in Computer Science from UOIT in 2015 under the co-supervision of Dr. Christopher Collins and Dr. Mark Hancock. My thesis focused on leveraging free-form ink annotations, made when performing a close reading, as implicit interactions to augment a literary critic’s analysis process with real-time context-specific metadata.

Graduate Student

I am a PhD candidate at the University of Konstanz, Germany. My doctoral studies are co-supervised by Dr. Christopher Collins and Dr. Daniel Keim.

My general research interest is in combining data mining and machine learning techniques with visual analytics to analyze text data.  In particular, I am working on the automatic analysis and visualization of transcribed spoken text data.

In context of the VisArgue Project, I am currently developing a visual analytics framework to analyze conversations and political debates.

Stephen McIntyre

I am a graduate student at the University of Ontario Institute of Technology (UOIT) currently completing my MSc in computer science. I have been a member of the vialab since September 2013 co-supervised by Dr. Christopher Collins and Dr. Mikael Eklund. My research interests include health informatics, working with big data and information visualizations. After completing my MSc I plan on obtaining my doctorate in the health science domain.

I completed my undergraduate degree in 2013 earning my Bachelor of Electrical Engineering and Management from UOIT. My Capstone project involved designing an RFID system for monitoring the temperature of infants in a hospital. By automating the process of taking their temperature we allow them to remain undisturbed.
