SHORT BIO

I am an Associate Professor at the Computer Science Department, Columbia University. I am also a co-founder of Articulate.AI that centers its efforts on harnessing the power of Conversational and Generative AI to empower and shape the future landscape of the workspace. Before that I was an Assistant Professor at UC Davis. I received my PhD at Language Technology Institute under School of Computer Science, Carnegie Mellon University 2017, working with Prof. Alan W Black and Prof. Alexander I. Rudnicky. I design algorithms for real-time intelligent interactive systems that coordinate with user actions that are beyond spoken languages, including non-verbal behaviors to achieve effective and natural communications. In particular, I optimize human-machine communication via studies of multimodal sensing and analysis, speech and natural language processing, machine learning and human-computer interaction.
