I graduated in Civil Engineering in 2003 from the Indian Institute of Technology (IIT) Madras and received my Ph. D. in 2009 from Northwestern University. Since then I have worked as a post doctoral researcher at University of Texas at Austin (2009-2010) and at Columbia University in the City of New York (2010-2012). I consider myself fortunate to have studied and worked closely with great teachers and mentors at various prestigious institutions. I am and will always be grateful to them.
My research interests are in the general area of computational solid mechanics with an emphasis on multi-physics modeling and simulation of material degradation. Topics include: creep and fatigue fracture in materials and structures, environmentally assisted degradation of materials including corrosion, characterization of advanced materials such as composites and super-alloys. A key research focus is on developing robust, stable and efficient numerical methods for evolving phase/crack interfaces using sharp and diffuse interface approaches.
More specifically, I am interested in understanding and predicting crack interface evolution using cohesive zone and continuum damage or phase field models. I am also interested in reactive transport modeling of multi-ionic electrochemical systems using sharp level set and diffused phase field methods. The emphasis is on developing efficient solution strategies for simulating processes involving multiple space and/or time scales within the framework of the finite element method. The computational methods and models I intend to develop are useful to study a wide array of applications in the areas of mechanics of materials and structures, geophysics, and biomedical engineering.
On going research projects include:
- Simulating iceberg calving using damage mechanics (funded by NSF)
- Modeling fatigue delamination in composite materials (funded by Vanderbilt Discovery Grant and ONR)
- Sharp and diffuse interface approaches for localized corrosion
- Simulating ultrasonic wave propagation in soft tissues with heterogeneities (funded by Vanderbilt Institute in Surgery and Engineering Pilot Grant)
