About Me
I am a Postdoctoral Research Scientist at the Department of Industrial Engineering and Operations Research, Columbia University, hosted by Professor Christian Kroer and Professor Garud Iyengar. I recently obtained my Ph.D. from the Operations Research Center at MIT in May 2024. My research is primarily in optimization—both theory and application—and often both simultaneously.
Update. I will join the Department of Computational Applied Mathematics & Operations Research at Rice University as an Assistant Professor starting July 2025.
