Brief Bio
Abhishek Halder is an Associate Professor in the Department of Aerospace Engineering at Iowa State University, and a Visiting Associate Professor in the Department of Applied Mathematics at University of California Santa Cruz.
His research
interests are in stochastic systems, control and optimization with application
focus on large scale cyber-physical systems. He is a co-founder of the annual NorCal Control Workshop that brings together systems-control researchers from academia and industry in the Northern California region fostering collaboration and professional networking. He is the creator and instructor for the course "Feedback
Control" in the California State Summer School for Mathematics &
Science (COSMOS) which teaches feedback control theory to 8-11
graders without using calculus or linear algebra. His research has been recognized with the O. Hugo Schuck Best Application Paper Award from the American Automatic Control Council, Applied Mathematics Research Award from UC Santa Cruz, Outstanding Doctoral Student Award from Texas A&M, and Best Dual Degree Thesis Award from IIT Kharagpur. He has been the Associate Editor of Systems & Control Letters (2022-present), IEEE Control Systems Society Conference Editorial Board (2019-present), IEEE Transactions on Aerospace and Electronic Systems (2019-20). Abhishek is a Senior Member of IEEE.
