Changan Chen 陈昌安

I am a Ph.D. student in Computer Science at UT Austin advised by Prof. Kristen Grauman. I am broadly interested at building machine learning models that perceive the world with multi-modalities and interact with the world. Currently, I work on embodied AI, audio-visual learning and acoustics modeling.

Previously, I spent five months working with Prof. Andrea Vedaldi and Dr. Natalia Neverova at FAIR, London. I was a visiting researcher at FAIR working with Prof. Kristen Grauman for two years. In my undergrad, I spent a wonderful year working with Prof. Greg Mori on sports video analysis and efficient deep learning, eight months working with Prof. Alexandre Alahi on social navigation in crowds, and eight months working with Prof. Manolis Savva on relational graph reasoning for navigation.

My first name is pronounced as /tʃæn'æn/ with the g being silent.

Research opportunities: I am happy to collaborate with motivated undergrad and master students at UT Austin. I am also happy to answer questions about my research. If you are interested, please send me an email.
