Background
I finished my MS in Geology (2009) at the University of Minnesota - Twin Cities, where I have lived for about 5 years now. I am originally from Hyderabad (also known as the "City of Pearls"), in southern India. I received a Integrated M.Sc. and B.Sc (Honors) in Applied Geology (2005) at the Indian Institute of Technology, Kharagpur (100 miles east of Kolkata), more famously known as the IIT.
Research Interests
I am interested in understanding the role played by fluids (groundwater, geothermal, hydrocarbon, CO2, etc.) in physical processes such as land surface deformation (uplift or subsidence), fault re-activation, advection of heat, triggering of earthquakes, disintegrating cap-rock, etc., by using numerical models of fluid flow in the upper crust. For example, in my MS work I used poroelastic modeling of InSAR-determined land surface deformation in Coachella Valley, California, to constrain both aquifer and shallow San Andreas Fault permeabilities (Appana et. al., submitted to GJI). This study has implications for both groundwater management in Coachella Valley and research related to the San Andreas Fault slip dynamics.
