Divy Pathak

Divy Pathak received the M.S. degree in Computer Engineering from Drexel University in 2015, where she is currently pursuing the Ph.D. degree in Electrical and Computer Engineering. She is the recipient of the 2017 IEEE Circuits and Systems Pre-Doctoral Scholarship.

She was a Research Scientist with Indian Space Research Organization from 2003 to 2006, where she was involved in analog signal processing modules for communication and remote sensing satellites. She was a Staff Engineer with STMicroelectronics from 2006 to 2013, where she focused on functional and electrical post-silicon validation of set-top box MPSoCs. She was an Intern with the IBM Thomas J. Watson Research Center from 2015 to 2016, where she was involved in power supply noise mitigation techniques for IBM POWER and Z Systems.

Her current research interests include circuits, systems, and micro-architecture design for post-Moore computing, including algorithms, modeling, optimization, and VLSI design for computing devices ranging from exascale systems to low-power internet of things. Her PhD thesis focuses on SMART on-chip power delivery for energy efficient computing.
