M. Tech from National Institute of Technology, Calicut (NITC) during 2003 - 2006

B. Tech (Mechanical Engineering) from Jawaharlal Nehru Technological University, Hyderabad (JNTUH)  during 1998 - 2002

Scientist at CSIR – National Aerospace Laboratories (CSIR – NAL) from 2006 – till date

Started the career in CFD at CTFD division of NAL with the RANS simulations of hypersonic flows involving in Base flows, Shock-Shock interactions, Shock- Boundary layer interactions and intake flows. Patched-grid and Overset-grid modules were developed and implemented individually and combinedly in  2-D version of RANS code, MB-EURANIUM. Efforts are going on to extend the overset capability to 3D as well, which will enable to simulate the store separation problems, multi-body dynamic problems, etc.

Shock-Expansion Tool, a little but useful tool for first cut results of supersonic flows past 2-D and axisymmetric bodies was developed, verified and validated successfully.

Involved in development of common CFD framework Euler code by implementing HLLC convective flux scheme, validating on different configurations, higher order reconstruction methods, etc.

Aerodynamic analysis of DO-228B aircraft with Sarakhshi antenna was performed by using the open source CFD code-SU2 for DLRL in association with IIT Kanpur to get RCMA clearance for test flight after installing the antennae by HAL Kanpur (TAD).

Currently working on aerodynamic analysis of SARAS aircraft PT3 configuration using the open source CFD code-SU2 to fine tune the solver settings for the purpose of using the same to analyse future configurations. Currently working also on SARAS propeller aerodynamic simulation using the sliding interface capability of the same open source CFD code-SU2 with the ultimate aim of simulating the flow past SARAS aircraft configuration with one propeller in switch-off condition.
