Biography

I am a Research Associate at the Oden Institute for Computational Engineering and Sciences at the University of Texas at Austin. I received a Ph.D. in Civil and Environmental Engineering from Carnegie Mellon University in August 2016. After finishing my Ph.D., I joined the Department of Mathematics at Louisiana State University as a Postdoctoral Fellow and worked on numerical methods and analysis of the peridynamics theory of fracture. I moved to UT Austin in August 2019 to further expand my expertise and knowledge in computational mechanics. My research interests include solids and granular media mechanics, fracture mechanics, multiphysics and multiscale modeling, and applications of neural networks to engineering problems.

In Fall 2021, I taught two undergraduate courses on numerical methods. I am serving the Journal of Peridynamics and Nonlocal Modeling as one of the associate editors and the Journal of Open Source Software (JOSS) as topic editor. Recently, I joined the editorial team of Scientific Reports as an Editorial Board Member.
