# Home I am currently a lecturer and a research fellow at the Math department and at its associated center CMSA at Harvard University (non-tenure assistant Professor). Here my mentor is ***Fields Medal*** laureate **Prof. [Shing-Tung Yau](https://en.wikipedia.org/wiki/Shing-Tung_Yau)**. Before this, I was a Ph.D. student at **Yale** university where I worked on the ***Stability and Convergence Issues in Mathematical General Relativity*** under the supervision of **Prof. [Vincent Moncrief](https://en.wikipedia.org/wiki/Vincent_Moncrief).** I also studied the propagation of elastic waves through random heterogeneous-anisotropic medium and their scattering properties under the supervision of Prof. **[Maureen Long](https://en.wikipedia.org/wiki/Maureen_D._Long)** at Geophysics Department-an application of the techniques used in the analysis of hyperbolic PDEs-in particular formulation of well-posed inverse problem.
