Short Bio

I'm a PhD student from the College of Information Sciences and Technology at the Pennsylvania State University. I'm super lucky to be mentored by my best advisor Prof. Honavar.

I work on machine learning for healthcare. My scientific goal is to advance the integration of machine learning into clinical practice by designing clinical AI systems that are informative, interactive, and affordable. My current research centers around narrowing the gaps between Data (Electronic Health Records (EHR) Data), Model (Continual Learning from Multi-modality Data), and Application (Clinical Conversational System):
