My research interests are broadly in Human-Computer Interaction (HCI). I study HCI to better understand and improve human interactions with AI and other complex algorithmic systems. I design and build computing systems to positively support users' online behaviors and interactions in a scalable and accessible way.
I received my B.S. and M.S., both in Computer Science, from the University of Illinois at Urbana-Champaign (UIUC), co-advised by Professor Lawrence Angrave and Professor Karrie Karahalios. I also worked with Professor ChengXiang Zhai in the Data and Information Systems Laboratory.

Ethical Web and Data Infrastructure in the Age of AI (EWADA) is an ambitious 3-year programme funded by the Oxford Martin School (OMS). Its mission is to reform the concentration of power on the World Wide Web by developing and deploying new forms of technical and legal infrastructure.
ClassTranscribe is a Microsoft sponsored online learning platform. I analyzed behavioral data of 1,894 users totaling more than 5 million interactions with the system to study students’ attitudes and behaviors towards caption-based video search. The results have been published at SIGCSE and ASEE.
I used a grounded-theory approach to code the qualitative data from a 22-participant interview study. The results provided insights into students’ folk theories, interaction strategies, perceived accuracy, satisfaction and fairness towards the NLP-based grading system. The paper was published at CHI 2021.
Being motivated to promote equity for students with disabilities and accessible learning opportunities for all students, we conducted surveys and interviews across several large courses in engineering and computing at UIUC to identify course components that engage students with and without disabilities. The paper was published at ASEE 2021.
I led the design and implementation of a 20-participant user study on an integrated friend-sourcing tool that helps visually impaired people with inaccessible web tasks to investigate users’ attitudes towards the tool, regarding friend-sourcing vs. crowd-sourcing, paid vs unpaid, privacy concerns, and impacts on their relationship. (SOUPS 2021)
I designed and developed an Android app using the Android Accessibility Service to automatically record users’ interactions with other apps on the phone. The logged data include gestures, screenshots, and view hierarchies. The data was used to mine user habits and generate task shortcuts.
