**About me**: I am an __Assistant Professor of Mathematics__ at Duke University, and a member of Duke Quantum Center. This fall, I will be visiting and co-organizing a semester-long program on quantum computing at IPAM UCLA. Previously, I was at University of California, Berkeley as a __Morrey Visiting Assistant Professor__ at Department of Mathematics (hosted by Prof. Lin Lin) and __Simons Quantum Postdoctoral Fellow__ at Simons Institute for the Theory of Computing (hosted by Prof. Lin Lin and Prof. Umesh Vazirani).
I received my PhD in mathematics from University of Wisconsin-Madison.

I currently serve as an editor of the journal __Quantum__.
My research is funded in part by NSF grant DMS-2347791 (previously DMS-2208416).

**Research Interests**:
My research interests lie broadly in applied and numerical analysis of partial differential equations. After joining Berkeley, I became intrigued by quantum algorithms. My current focus is quantum related problems and quantum computing, in particular, quantum algorithms for differential equations including unbounded Hamiltonian simulation and other classical differential equations.
