My name is Jin-Peng Liu (刘锦鹏). I am a Postdoctoral Associate at Center for Theoretical Physics, Massachusetts Institute of Technology, mainly hosted by Aram Harrow from 2023. I was a Simons Quantum Postdoctoral Fellow at Simons Institute and UC Berkeley, hosted by Umesh Vazirani and Lin Lin in 2022-2023.

I received my Ph.D. degree in AMSC program at University of Maryland in 2022, advised by Andrew Childs. Prior to that, I received my B.S. degree in Chinese Academy of Sciences Hua Loo Keng Class at Beihang University in 2017, supervised by Ya-xiang Yuan.

My research focuses on *Quantum for Science*. I attempt to develop, analyze, and optimize provably efficient quantum algorithms for challenges in natural and data sciences, including topics: (i) robust quantum simulations; (ii) efficient quantum scientific computation; (iii) scalable quantum machine learning, toward end-to-end applications in areas such as quantum chemistry, biology and epidemiology, fluid dynamics, finance, machine learning, and artificial general intelligence.
