Hi there! I’m a Ph.D. candidate in Informatics at the Pennsylvania State University, advised by Dr. John Carroll.

Research Interests:

I'm interested in the human-centered design for data & AI empowered educational technologies. With a combination of data science and user research methods, I investigate the process of designing and designing innovative technologies for educational purposes, and how to properly integrate human perspectives in the process.

Research experience


Graduate Researcher

Teaching & Learning with Technology

Aug 2022 – Present Penn State
Our mission is to innovate with technologies that transform teaching and learning in positive and enduring ways. I empower technology development and strategic decision-making through data science.

UX Researcher

Naver Labs Europe

Jan 2022 – Aug 2022 Remote collaboration
Lead usability studies to evaluate their codeless app development system. Conducted thorough benchmarking analyses of the product’s usability, summarizing user feedback and expert reviews to identify opportunities for improvement.

PhD Student

Collaboration and Innovation Lab

Sep 2020 – Present Penn State
I lead multiple research projects to address societal problems in technology advancement. Synthesize literature, propose hypotheses, develop research plans, execute quantitative & qualitative studies, and report core findings to relevant communities.

Research Associate


Sep 2019 – Aug 2020 Purdue
Our mission is to enable the holistic transformation of STEM education by bridging research & practice. I conducted quantitative and qualitative research for several projects.

Master student

Health Ergonomics Analytics Lab

Aug 2017 – Aug 2019 Purdue
My research investigated the data-driven cognitive modeling in healthcare. I proposed and validated machine learning assessment for robotic surgery training, based on eye-tracking and EEG signals.
