Hi, I am

Abhraneel
Sarma.

I am a PhD student in Computer Science at Northwestern University, advised by Professor Jessica Hullman and Professor Matthew Kay.

Broadly—I am interested in studying how people make sense of uncertainty information which arise in a typical data analysis pipeline. Specifically—I have developed tools which help analysts to surface the uncertainty in their data analysis process itself (the multiverse R library), or studying how users interpret uncertainty visualisations in missing data contexts or multiple comparison scenarios.
