Gagan grew up in Karnal, a town famous for its Basmati rice, NDRI and Kalpana Chawla. He is the first student from Karnal to clear the JEE. He was part of the first batch of students at IIT Delhi who got the degree of Five-Years Integrated M. Tech in Mathematics and Computing in 2001. Gagan was the batch topper at IITD in the 7th semester with a SGPA of 9.47 on a 10-point scale. After IITD, he joined a startup called Evalueserve in Gurgaon and helped build it up from scratch. Evalueserve now has 3500+ employees, 500+ clients and has operations in 7 countries!! Gagan got his first promotion within a few months of joining the company. While at Evalueserve, Gagan lead many teams that worked on projects on Intellectual Property Asset Management, Patent Portfolio Valuation and Patent Infringement Analysis for Fortune 500 companies. After working for two years with Evalueserve, Gagan realized that his true passion lies in research, teaching and mentoring students. He then went to do a PhD from the Department of Computer Science and Automation, IISc Bangalore. During his PhD, he worked with Prof. C. E. Veni Madhavan on the Number Field Sieve and with Prof. P. Vijay Kumar on Sequences. The research resulted in an analysis of the large prime variations of the lattice sieve and comparison of its performance with the line sieve. The research also improved the data rate in a CDMA network by developing a new family of low-correlation sequences. During the seven years he spent at IISc Bangalore, he tried learning Kung Fu, swimming and volleyball, failing majestically at each sport! During his studies, Gagan visited several institutes for research collaboration and for delivering lectures like National Institute of Standards and Technology, USA; Institute for Experimental Mathematics, University of Duisburg-Essen, Germany; Ecole Polytechnique, Paris, France; Federal Office for Information Security (BSI), Bonn, Germany; Universidad de Cantabria, Santander, Spain; Universite de Montreal, Canada; University of Kassel, Germany; Lahore University of Management Sciences, Pakistan; The Institute of Mathematical Sciences, Chennai; Harish-Chandra Research Institute, Allahabad. After his PhD, he taught at LNMIIT Jaipur for an year before joining the School of Computing and Electrical Engineering IIT Mandi. It was a time when IIT Mandi had just started, and he helped setup the systems and processes for the Institute Library, Computer Science Laboratory, National Service Scheme, Mess operations, Scholarships and the Programming Club. Since 2012, Gagan has been at DAIICT. Apart from being the Warden of Hall of Residence, Men, he is a member of the Placement Committee and the Disciplinary Action Committee. He has taught courses on Probability Theory, Statistics, Cryptography, Computer Graphics, Discrete Mathematics and Information Theory to B. Tech, M. Tech as well as MSc IT students. Gagan is currently guiding one PhD student in the area of secret sharing and secure computation. When he is not wearing the hat of a professor, he performs standup comedy. He performed at Synapse 2019 to an audience of 1500+ people.
