I obtained my PhD in mathematics from the University of Nebraska-Lincoln in 2012, and my thesis advisor was Mohammad A. Rammaha. From 2012 to 2015, I was a postdoctoral fellow working with Edriss S. Titi, at the Weizmann Institute of Science in Israel. During 2015-2016, I was a lecturer at Texas A&M University. Currently, I am an Associate Professor at Florida International University. 

 

Research Interests:  I am interested in the analysis of nonlinear partial differential equations, such as the Navier-Stokes equations and nonlinear wave equations. I study well-posedness, regularity, finite-time blow-up, and the long-term behavior of solutions.
