Assistant Professor

About Me

Abhishta is an assistant professor at the Industrial Engineering and Business Information Systems group at University of Twente.

His research focuses on empirically measuring the economic/financial impact of cyber attacks. In order to do so he devices/adapts data-driven economic impact assessment techniques. He looks to help organisations make well-measured investments in security.

His doctoral research was funded under NWO project D3 – Distributed Denial-of-Service Defense: protecting schools and other public organizations. You can access a copy of his doctoral thesis here.

Other than finding (un)cool methods of finding the “devil” in financial details he is also involved in teaching and guiding students. From time to time he also delivers lectures to executives and collaborates with companies to help them with security decision making. He is also a member of behavioural data science incubator at the faculty of BMS at the university, where he contributes to solving social science problems using data science.
