About Me

I am a third year PhD student in computer science at the University of Pittsburgh researching human-computer interaction (HCI) natural-language processing (NLP) systems. I am advised by Dr. Aakash Gautam and co-advised by Dr. Xiang (Lorraine) Li.

I received my B.S. in computer science at the University of Pittsburgh in 2023. During this time, I did educational NLP research with Dr. Diane Litman and developed a speaker segmentation pipeline for the APLS project under Dr. Dan Villarreal.

Research Interests

My research focus examines how community-focused practices within HCI (e.g., participatory design) can elevate NLP systems for participant benefit.

The big questions of my research are:

1. What can researchers do to center the participant(s) when developing NLP systems?
2. How can NLP systems be used to assist participants in their goals?
3. When should NLP technologies be considered and what are their long-term outcomes?

Major Updates
