Brief Bio

I am an associate professor in the Graduate School of Artificial Intelligence and School of Computing at KAIST. Prior to working at KAIST, I was an assistant professor in the School of Electric and Computer Engineering at UNIST, and before that I was a postdoctoral research associate at Disney Research, working under the supervision of Professor Leonid Sigal. I did my Ph.D. in computer science at University of Texas at Austin, under the supervision of Professor Kristen Grauman. During my Ph.D. I also closely collaborated with Professor Fei Sha at University of Southern California.

I am also a co-founder and CTO of AITRICS, an AI startup company located in Seoul.

Here is my (outdated) CV.
 

Vacancies

To prospective master students
If you want to join our research group, please contact me as early as possible, so that you can have a short-term internship before applying to the master program. Also, please be aware that as a newly instated policy, I will only hire students planning to pursue Ph.D. study under my supervision.

To prospective Ph.D. students
If you want to do Ph.D. study under my supervision, then I recommend you to apply to the master’s program first (The master program at KAIST is an academic degree program and you will be fully supported). Please note that I can take only a limited number of Ph.D. students each year as advisees (currently three), and will put higher priorities on students who have done master’s study under my supervision. However I will still consider few qualified applicants outside my group as my advisees.

To prospective postdocs
I am constantly looking for postdocs with strong background in deep learning, preferably with experience on drug discovery, ML systems, or real-time computer vision. Please send me your CV if you are interested.

Research Interests

My research interest is mainly on developing novel models and algorithms for tackling new challenges in deploying artificial intelligence systems to various real-world application domains. Regarding machine learning problems, I am mostly interested in the following topics:

  • Low-resource learning: meta-learning, network pruning & quantization, deep generative models, self- & semi-supervised learning
  • On-device learning: network compression (pruning, quantization, and knowledge distillation), continual learning, federated learning
  • Safe and secure learning: uncertainty modeling & quantification, robustness to distributional shifts, defense against adversarial attacks
  • Large-scale learning: meta-learning, neural architecture search, distributed & federated learning

    • The application domains of interests include but are not limited to, visual recognition, natural language understanding, speech recognition, automatic drug/material discovery, healthcare and finance.
