I am a third-year PhD student in Human-Centered Computing at Georgia Tech specializing in Cognitive Science and Human-Computer Interaction. I am working with Dr. Ashok Goel at the Design&Intelligence Lab (DILab). In my research, I leverage theories, methods and techniques from cognitive science, HCI, and CSCW to understand the design, evaluation and impact of community-facing conversational agents within online human communities. Currently, I am using mixed-methods approach to explore the design of community-facing conversational agents to mediate online learners' community-building process.

I received my bachelor of science degree from University of Washington, Seattle in informatics and psychology. I worked closely with the Department of Human-Centered Design and Engineering, the Information School, the DUB group, and the psychology department on several research projects during my undergraduate study. At UW, I worked in personal health informatics, patient-provider collaboration, user value scale, computing education, disaster information management, and health and risky behaviors. You can learn more about my past research projects below.

I am a plant parent, cat lover, and sci-fi show enthusiast.

RESEARCH

Active Projects


online communities
Designing and Evaluating AI agent for Community Building in Online Education
Collaborators: Shan Jing, Ida Camacho, David Joyner, Ashok Goel
Georgia Tech School of Interactive Computing

We are designing and developing an AI agent to help online learners build communities and social connections. We are interested in whether the community-building AI agent can help improve students’ feeling of social presence. I conducted literature review on community building in online learning, situated learrning, social cognitive theories; Designing experiments to evaluate community-building agent; Conducting semi-structured interviews to understand online learners’ current community-building practices.

human-AI interaction through conversation
Measuring and Predicting Students' Mental Model of Virtual Teaching Assistants
Collaborators: Koustuv Saha, David Joyner, Ashok Goel
Georgia Tech School of Interactive Computing

We are exploring the feasibility of measuring human perception and attitudes of the agent through analyzing the conversations between human and virtual agent. The goal is to design conversational agent that can detect and adjust to user perception and attitudes towards the agent. I conducted literature review on human-AI interaction and technology perceptions; Composed IRB protocol; Designed bi-weekly surveys to measure students’ perception about the agent to provide ground truth data; Conducted quantitative statistical analysis to infer changes in students’ perception and conversa- tions with the agent; Analyzing conversations between student and virtual agent using NLP techniques such as sentiment analysis, word embeddings (word2vec)

Past Projects

Leveraging Behavioral and Physiological Feedback in the Design of Affect-Sensitive Distance Learning
Collaborators: Hong Li, David Joyner, Thomas Ploetz, Lauren Wilcox, Betsy DiSalvo
Georgia Tech School of Interactive Computing

Worked on exploring the feasibility of leveraging wearable technology and other types of sensing data to gather more context about online learners.

Predictors of Sexual Revictimization
Collaborators: Debra Kaysen
University of Washington, Center for the Study of Health and Risky Behaviors (CSHRB)

This project is an individual project advised by Dr. Debra Kaysen and was presented at the 2016 Undergraduate Research Symposium at University of Washington. Women who experienced sexual assault are 2 – 3 times more likely to experience sexual revictimization (SR). Factors that predict risk of SR include emotion dysregulation, guilt, and lower heart rate reactivity when facing sexual threats. These factors overlap with tonic immobility (TI), which is characterized by victim’s diminished or absent physical or vocal response during sexual assault ( “freeze” response).  Post-traumatic maladaptive cognitions also may increase risk for SR, either directly or through increasing risk of TI. Based on prior literature, my hypotheses are: 1. Higher TI will predict higher SV risk; 2. More severe maladaptive cognitions will predict higher SV risk; 3. TI will be predicted by maladaptive cognitions. Research findings suggest that prevention efforts may want to target women who experienced prior TI as a means of preventing future revictimization. These prevention efforts may be more effective if they include cognitive interventions.
