Jia-Lin Hau Monkie

AI / DS Fraud Modeling Senior Associate · JPMorgan Chase · JiaLin.Hau@gmail.edu

I am a Ph.D in Computer Science from University of New Hampshire (UNH), a member of the Reinforcement Learning and Robustness Lab (RLsquared) and my advisor is Marek Petrik. My research mainly focus on computational efficient algorithm for risk averse data driven decision making. I currently work as a AI / Data Science Full Time Associate at JP Morgan Chase and Co. and I have experience working on fraud modeling, strategy gap detection, and big data optimization.

I am highly interested in Reinforcement Learning, Actuarial Science, Deep Learning, A.I, Machine Learning and Risk Analysis. Beside learning and coding, I enjoy traveling, scuba diving, playing computer games, and basketball.

Jia Lin Hau
Fall 2021
Explored Multi Arm Bandits (MAB) algorithms and their performance in adversarial domain.
