Research | About Me

“If I have seen further, it is by standing on the shoulders of giants.“
– Isaac Newton

My research philosophy is to work on problems that not only advance our understanding of the fundamental questions in optimization and machine learning, but often also has a positive impact on the society through ensuring algorithmic fairness.
