Background

I am a Computing and Information Sciences Ph.D. student at Rochester Institute of Technology, working with Professor Cecilia O. Alm in the Computational Linguistics and Speech Processing Lab (CLaSP). My research focuses on interactive machine learning and federated learning for multimodal affective computing.

Research Interests

My research interests include multimodal machine learning, interactive machine learning, affective computing, natural language/speech processing, personalized federated learning, and Reinforcement Learning.
