Yiping Lu

I am a Courant instructor at Courant Institute of Mathematical Sciences, New York University, and an incoming tenure-track assistant professor at Industrial Engineering & Management Science, Northwestern University. I received my Ph.D. degree in applied math from Stanford University in 2023 and my Bachelor’s degree in applied math from Peking University in 2019.

Advertisement I am happy to host (remote) undergraduate/graduate visitors and looking for Ph.D. Students. Prospective Students see here. You can also find information about my research here

To anyone: I would appreciate (anonymous) feedback about anything!

The long-term goal of my research is to develop a hybrid scientific research discipline that combines domain knowledge (differential equation, stochastic process, control,…), machine learning and (randomized) experiments. To this end, I’m working on an interdisciplinary research approach across probability and statistics, machine learning, numerical algorithms, control theory, signal processing/inverse problem, and operations research.

Here’s my research statement and my latest CV.

Fine-grained research interest: Scientific Machine Learning (AI4Science), Stochastic Simulation, Machine Learning Theory (RKHS, Empirical Process, Deep Learning), Inverse Problem, Robust Machine Learning
