I am an assistant professor in Halıcıoğlu Data Science Institute with affiliation to Computer Science and Engineering Department at UC San Diego.
I direct the Trustworthy Machine Learning Lab at UCSD. My research vision is to make the next generation AI systems and deep learning algorithms more robust, reliable, explainable, trustworthy and safer.

I’m open to collaborations with highly motivated students with strong machine learning and mathematical backgrounds!
I received my PhD (2020) in Electrical Engineering and Computer Science from MIT advised by Prof. Luca Daniel on the topic of Robust Machine Learning with focus on Neural Networks, and M.S. (2013) and B.S. (2011) degrees in Electrical Engineering from National Taiwan University advised by Prof. Tzong-Lin Wu and Prof. Peter Shiue on the topic of microwave circuits and combinatorics. Prior to UCSD, I spent 1 year in MIT-IBM Watson AI Lab and several research internship in Google DeepMind, IBM Research and Mitsubishi Electric Research Lab.
