About [CV]

I’m currently working as postdoctoral researcher with Prof. Alexandre Proutiere in School of Electrical Engineering at KTH, Sweden. I finished Ph.D program in School of Electrical Engineering at Korea Advanced Institute of Science and Technology (KAIST), South Korea, under the supervision of Prof. Yung Yi and Prof. Jinwoo Shin.

I’m interested in understanding and improving practical systems based on theoretical model and analysis, where my research lies at the intersection of applied mathematics and network systems including wireless network, social network, and probabilistic graphical model. Currently, my major focus is social models with certain purposes such as crowdsourcing and information spread. Here are my research topics and keywords:

Reinforcement Learning - regret minimization, multi-armed bandit, Markov decision process

Social Network - strategic diffusion, influence maximization, Ising model, hitting time analysis

Learning in Graphical Model - crowdsourced classification, belief propagation, correlation decay

Wireless Network - rate adaptation for 802.11n/ac, network virtualization, multi-armed bandit


You can also find my papers listed in Google Scholar.
