Human-Computer Interaction; Artificial Intelligence; Education; Social Computing
My research interests are broadly in Human-Computer Interaction, Artificial Intelligence, and Education. I study human-computer interaction (HCI) to better understand and improve human interaction with AI and complex algorithmic systems. I design and build intelligent systems to support scalable and accessible teaching and learning through a computational lens.
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.

[08/2020]: A LIGHTNING TALK ACCEPTED AT CRA 2020
I gave a lightning talk "ClassTranscribe: Addressing the COVID Challenge and Promoting Better Equity in Education" at CRA 2020.
ClassTranscribe is a Microsoft sponsored e-learning platform. I analyzed behavioral data of 1,894 users totaling more than five million interactions with the system. We published the results at SIGCSE and ASEE. My on-going research is to further investigate students’ attitudes and behaviors towards searching and learner sourcing.
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 AI grading system. The paper has been accepted by CHI 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. The user study investigated users’ attitudes towards the tool, regarding friend-sourcing vs. crowd-sourcing, paid vs unpaid, privacy concerns, and impacts on their relationship.
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. We are using the data to mine user habits and generate task shortcuts.
In this study, I used the ZIPT system to collect and analyze data from 20 participants on their opinions regarding privacy concerns over popular mobile apps (Facebook, Amazon, Chase, etc.) The results shed light on mobile users’ privacy concerns beyond their personally identifiable information (PII).
A VR game on Oculus, created with Unity. I implemented several attacking modes of the Ninja. I also ran user studies and enhanced the user experience on decreasing dizziness, improving prompts and controlling gestures, and enriching the experience of the boss fight.
