Pursuing Ph.D., advised by Anita Sarma in the Electrical Engineering & Computer Science department at Oregon State University. I work at the intersections of Human-Computer Interaction, Software Engineering and Cognitive Science.

My work is focused around understanding how humans make decisions when interacting with interfaces, specifically programming interfaces. I study developers and data scientists to identify their intentions behind the interactions. I aim to understand and model cognitive processes in experts and end-users of computing to make computing tools and platforms more assistive to human reasoning and decision making.

Ongoing Projects/Publications

Details about ongoing projects and publications.

  •   Decison mechanisms in data workers - from Machine Learning experts to end-user data analysts.
    How do data scientists make analysis decisions? To answer this question, I studied the various challenges faced by data workers in different roles and with different motivations. I also study how these data scientists in various roles are driven by varying motivations, and how they break their tasks down into decisions, and what affects their decisions, in search for ways to make data science tools support decision processes.

  •   Programmer behavior on social media platforms to understand self-expression and identity.
    How does the programming community use powerful social media outlets to express identity and disemminate information? And how does it affect the rest of the programming community? I study programmers' use of social media, their behavior and interaction with the community to look for avenues to improve experiences. Maybe even spark a conversation about social media to diversify thoughts within computing!
