news

Oct. 2016: I will be joining the neXus group at Microsoft Research in Redmond, Washington as a postdoctoral researcher in October, 2016.

Apr. 2016: The final version of my PhD dissertation, Why Visualization? Task Abstraction for Analysis and Design is available here.

Feb. 2016: I attended the Dagstuhl seminar on Data-Driven Storytelling between February 7th and 12th along with a great group of researchers, designers, and journalists. A book on data-driven storytelling, written collaboratively by the seminar participants, is forthcoming.

expertise

I completed an PhD in Computer Science in 2016 at the University of British Columbia, where I was a member of Tamara Munzner's InfoVis group. I completed a M.Sc in Human-Computer Interaction in 2011 (also at UBC), as well as a B.Comp in Cognitive Science from Queen's University in 2009.

visualization and interface design

I design visualization tools and techniques for data analysis and communication: I write code, I sketch, and I explore and transform data.

→ examples: [Portfolio Sandbox] [SoundConsensus] [ShinyFork]

human-centred quantitative evaluation

I conduct controlled experiments as a way to understand human capabilities with respect to perception and attention (and sometimes these results have actionable implications for human-computer interface design).

→ more info: [CHI 12] [WH 11] [BComp 09]

human-centred qualitative evaluation

I evaluate current data analysis and communication processes, work-in-progress designs, and deployed visualization tools: I conduct work domain analyses, interview studies, chauffeured demos/walkthroughs, and field studies.

domains

data journalism and storytelling

As part of a collaboration between the UBC InfoVis Group and the Overview Project, I conducted six case studies of journalists who used Overview to investigate and report on large text document collections. Our findings provided transferible lessons for document visualization design.

My goal is to provide journalists and storytellers with better tools for producing presenting information to readers, such as better tools for producing visual timelines.

energy management and conservation

I have collaborated with a company that develops enterprise energy analysis and reporting software and designed visualizations for analyzing and monitoring energy usage in large portfolios of buildings. I consulted with various stakeholders and prospective users, envisioning ways to interactively locate patterns and anomalies.

health and fitness

My M.Sc research pertained to the design and evaluation of C-TOC, a computerized cognitive assessment tool intended for early detection of dementia. I studied the use of C-TOC prototypes by healthy older adults and by adults with diagnosed mild cognitive impairments.

→ more info: [ADAD 14] [CHI 12] [MSc 11]

Prior to my M.Sc, I worked in the area of exercise video games (aka active games): I studied the role of physical exertion on cognitive task performance. I also designed GAIM, an XNA/C# toolkit which allowed players with different input peripherals to play active games together.
