Research Statement

Humans, just as much as technology, are at the crux of many of our cyber security challenges, as both the problem and the solution. Humans are the instigators (i.e., adversaries), the weakest links (i.e., end-users) and, the defenders who anticipate, plan, and execute responses to emerging threats (i.e., security analyst). Therefore, solutions to cyber security challenges must adequately address these different human dimensions of security.

Prashanth examines how human behavior affects information security and privacy to develop models of effective interventions that reduce the risk from attacks and promote safe behaviors online. His research aims to characterize adversarial behaviors, and strategies to inform incident response; measure teamwork and decision-making of security analysts to augment security defense performance; and, uncover biases in end-user decision-making that compromise security and privacy.

Prashanth's dissertation work was a finalist for the Human Factors Prize on Cyber Security in 2017. He received the Best Student Paper Award for his work on multi‐agent models of teamwork in cyber defense at the Human Factors and Ergonomics Society annual conference in 2014. His professional activities include journal review for Computers in Human Behavior, Human Factors and Cognitive Engineering and Decision Making.
