Graduate research:

Research Assistant, Marquette University, Milwaukee, WI, August 2018 - July 2020
Research Assistant, University of New Mexico, Albuquerque, NM, February 2016– August 2018

I worked with Professor Majeed M. Hayat as a PhD student at the university of New Mexico and Marquette University on Probabilistic modeling of cascading failures in power systems. Research included Markov-Chain based Model of a coupled power grid network including data integrity and the role of human operators on the reliability of Power Grid. . During my time as a graduate student I worked in two research projects funded by DTRA (Defense threat reduction agency) under DoD (Department of defense) titled "Probabilistic characterization of precursors to WMD-induced cascading failures in the electric-cyber infrastructure: An integrated physical-network and human-factor approach; DTRA Award Number: HDTRA1-13-1-0020" and NSF (national science foundation) titled "Revolution through Evolution: A Controls Approach to Improve How Society Interacts with Electricity; NSF(CRISP Type 2) award Number: 1541148"
PhD Dissertation title : "Probabilistic framework for balancing smart grid's performance enhancement and resilience to cyber threat."
