Assistant Professor of Computer Science

College of Engineering and Computer Science


Khoa D. Doan is currently an Assistant Professor of Computer Science in the College of Engineering and Computer Science at VinUniversity, Hanoi, Vietnam. Prior to his current appointment, he worked as an AI Researcher at Baidu Research, USA. He received his PhD in Computer Science at Virginia Tech, and MS in Computer Science at the University of Maryland, College Park. In the past, he worked as a senior Software Engineer at various enterprise software companies, and as a senior Data Scientist/Researcher in high-performance and distributed computing projects at NASA and various advertising companies, such as Criteo AI Lab. Besides research, he also spends time engaging and advising AI technology with startups.

His research focuses on developing computational frameworks that enable existing complex machine learning models to be more suitable for practical uses in various domains such as computational advertising, computer vision, and natural language processing. Specifically, his research focuses on improving the following aspects of existing models: (i) training, (i) inference, (iii) realistic assumptions, and (iv) security understanding. Currently, his research activities include, but are not limited to, the following three themes: deep information retrieval and its applications, generative models, and robust and reliable machine learning. He has been a program committee member for premier conferences such as ICML, CVPR, ECCV, ICCV, ICLR, and NeurIPS.
