About Me

I am currently working as an Assitant Manager in System Integration at Ola Electric.
I work with simulations to define vehicle-level technical specifications (to meet product requirements), define system-level requirements, predict thermal performance, define cooling requirement and design cooling strategy.

I completed my B.Tech in Mechanical Engineering from NIT Bhopal, India under the guidance of Dr. R.K. Dwivedi, Dr. Vinod Yadav and Dr. Deepak Kumar. My research focus was in the field of soft matter and biomedical engineering and my academic projects were advancements in manufacturing and automotive engineering. I have worked with the Socket Sense research group at KTH Royal Institute of Technology, Sweden under the guidance of Prof. Dejiu Chen. My research involved data-driven analysis of transfemoral amputees to design personalised comfortable prosthetic sockets. I have also worked with the Biomechanics Research Unit at KU Leuven, Belgium under the guidance of Prof. Liesbet Geris. We studied the surgerical treatment of Osteoarthritis by designing a FEA model to simulate the regeneration of articular cartilage inside scaffolds.

I have industry experience in automotive performance (motor, li-ion cells, battery and vehicle), control strategy design, computational modeling and data analysis. I have research experience in bio-medical engineering, soft matter, computational mechanics and FEA.

In my free time, I enjoy reading books. I like running, trekking, adventure sports, badminton and swimming. I love exploring cities to discover food trucks, cafes, bakeries, pizzerias and fine dine restaurants to track down the gourmet cuisines.
