Prof Krebs’ research projects on international fact-finding, biases in counterterrorism decision-making, and human-machine interaction in drone warfare, have influenced decision-making processes through invitations to brief high-level decision-makers, including at the United Nations (CTED, Office of the Secretary-General), the United States Department of Defense, and the Australian Defence Force.

Her recent research awards include the David Caron Prize (American Society of International Law, 2021), the ‘Researcher of the Year’ Award (Australian Women in Law Awards, 2022), the Australian Legal Research Awards (finalist, Article/Chapter (ECR), 2022), and the Vice-Chancellor’s Researcher Award for Career Excellence (Deakin, 2022).

Before joining Deakin University, Prof Krebs has taught in several law schools, including at Stanford University, University of Santa Clara, and the Hebrew University of Jerusalem, where she won the Dean’s award recognizing exceptional junior faculty members.

She earned her Doctorate and Master Degrees from Stanford Law School, as well as LL.B. and M.A., both magna cum laude, from the Hebrew University of Jerusalem.
