Vanakkam! (That’s 'hello' in Tamil, my native tongue.)

I am Krishna, a third-year Research Assistant at the Media Computing Group, Aachen.

I’m driven by the need to help the society, in the current information age, realize the potential of data through data analysis. I design, build, and investigate interaction techniques that make data analysis easier to perform, learn, and present. I envision my research to remove some fog in the metaphorical-data-analysis glasses, resulting in clearer and more accurate insights.

If you are interested in doing a B.Sc. or M.Sc. thesis with me, drop me an email with your résumé, grade sheet(s), and idea(s) that interest you.

I usually have some open thesis topics, but I’m also interested in building a thesis around any initial ideas you might have.


StatLets is a web-based prototype that uses a flow-based programming canvas, where users can place (and organize) different statistical analysis widgets. The user can view and edit the underlying R code of the widget using the editor interface, which is integrated into StatLets. (read more)
StatPlayground is a web-based prototype, that allows users to directly manipulate characteristics of data (e.g., mean, variance, outliers) through visualizations (e.g., box plot) and view the resulting effect on the inferential statistics (e.g., p-value, effect size) and vice versa. (read more)

Interactivity: Demo at CHI 2017.
Personal Photonics aims to create new interaction techniques and user interfaces for photonics components, systems, and tools, to make them easier to use for makers, designers, artists, and other non-engineers, putting the photonics industry on center stage of the Open Innovation movement.

Role: Investigating low-cost versions of 3-D trackers
Statsplorer is a software tool that allows users to do statistical analysis by interacting with visualizations. It guides the user to select appropriate statistical analysis tasks based on her research questions. It also prevents common statistical analysis mistakes and promotes understanding by collocating appropriate visualizations with statistical analysis results. (read more)
