I consider myself a well rounded researcher with expertise in Optimal Control, Adaptive Control, Estimation theory, and Dynamic Systems Modeling. I pride myself on being a versatile aerospace engineer with practical knowledge in instrumentation, a quick study with sound mathematical fundamentals and a tinkerer with constant curiosity for the unknown. I love working on my car and travelling.
I am currently a Research Scientist II at The University of Texas at Arlington Research Institute (UTARI). My work at UTARI is focused on implementing Control Systems for a range of Biomedical device prototypes developed in-house. I received my Bachelor of Technology (2010) in Aerospace Engineering from Indian Institute of Technology Madras. A major part of my undergraduate thesis formulates control of unmanned aerial vehicles for remote surveillance. I was awarded a Doctoral degree (2015) in Aerospace Engineering by The University of Texas at Arlington for my work on a novel control architecture which combines aspects of Adaptive and Optimal Control for System Identification and Closed loop stability simultaneously.
I am a member of professional organizations such as IEEE, AIAA, and ASME with active research contributions in the form of publications. Although majority of my published academic work focuses on theoretical Control Systems, my interests include hands-on implementation (instrumentation) and testing. I am also an avid programmer and an automotive enthusiast with autocross experience.

University of Texas at Arlington
Aerospace Engineering, Ph.D. — 2010-2015
The doctoral dissertation is titled “Aspects of Intuitive Control: Stabilize, Optimize, and Identify”. It presents a novel control architecture bridging the gap between control and estimation from adaptive control literature and combines them into one powerful framework for Stabilization, Optimal control and eventually Identification of an unknown dynamic system. State of the art Intelligent control techniques such as Policy Iteration and Value Iteration are improved in development of theory and applications across various disciplines of Aerospace Engineering are shown in the form of case studies.
