About

Divyesh Unadkat is a Senior Staff R & D Engineer at Synopsys Inc., Hyderabad. Previously, he was affiliated as a Scientist and Senior Software Engineer with the Foundations of Computing Group, TCS Research, Tata Research Development & Design Centre (TRDDC), Pune.

Divyesh is passionate about research and development challenges in the area of Artificial Intelligence, specifically in the sub-areas of SW/HW Verification, SAT & SMT Solving, Automated Theorem Proving, Data/Control-flow Analysis, Compilers, and Applied Machine Learning.

Divyesh has completed his Ph.D. studies in Software Verification under the supervision of Prof. Supratik Chakraborty and Prof. Ashutosh Gupta. He was affiliated with the Centre for Formal Design and Verification of Software (CFDVS) at the Indian Institute of Technology Bombay (IITB). Divyesh has received his Bachelor of Engineering degree in Computer Engineering from Dharmsinh Desai University (DDU).

During his leisure time, Divyesh loves throwing a ball (table tennis, volleyball, football, cricket), stretching his physical limits (exercise, yoga, pranayam, brisk walks), playing with fire & ice; sugar & spice; flour & rice (resulting in nice meals and exotic delicacies), indulging in art forms (suspense & thriller novels, rock & pop music, Hollywood action & romcom movies), exploring the locale (trekking, nature's trail, site seeing, roaming in malls), adding creativity even to day-to-day mundane things and calling up friends and family.
