Feng Bao Associate Professor Timothy Gannon Endowed Professor Department of Mathematics Florida State University Email: bao@math.fsu.edu Office: LOVE Building 312
I am the Timothy Gannon Endowed Associate Professor of Mathematics at Florida State University. My research interests include data assimilation and stochastic inference, stochastic optimal control, mathematics for machine learning, and uncertainty quantification. In addition to receiving the NSF CAREER Award in 2022, I serve as the PI (or institutional PI) of six major DOE projects, including those that won the DOE AI for Science Call in both 2021 and 2024.
