About Me

Human-Computer Interaction; Social Computing; Human-Centered AI; Learning Technologies

I am a 5-year BS-MS student in Computer Science at the University of Illinois at Urbana-Champaign (UIUC), co-advised by Professor Karrie Karahalios and Professor Lawrence Angrave.

My research interests are in Human-Computer Interaction and Education, with a focus on studying how people interact with Artificial Intelligence (AI) systems, investigating societal issues such as misinformation, bias, privacy concerns caused by AI, and designing new technologies and mechanisms to address these problems. I am motivated to provide people with a more informed, fair, secure, accessible, satisfying, and engaging experience when interacting with AI systems.

Currently, I am leading several projects to explore students’ attitudes and behaviors towards searching and learner sourcing, and building an interactive intelligent educational system that can “teach.” I am also working as a Teaching Assistant for CS410: Text Information Systems, with Professor ChengXiang Zhai.

Portfolio

ClassTranscribe is a Microsoft sponsored e-learning platform. I analyzed behavioral data of 1,895 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 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.

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 used a grounded-theory approach to code the qualitative data from a 20-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 is in submission at CHI 2021.

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.
