Phillip Rogaway rogaway@cs.ucdavis.edu Department of Computer Science One Shields Ave University of California Davis, CA 95616 USA I am—or was—a professor in the Department of Computer Science at the University of California, Davis. I have also been a visiting professor at a bunch of other places, including many years at Chiang Mai University (TH) and extended stays at Chulalongkorn University (TH), ENS Paris (FR), ETH Zürich (CH), and the Isaac Newton Institute (UK).

Most of my research has been on cryptography, the mathematical treatment of secure communication. I did my undergrad at UC Berkeley and my Ph.D. at MIT, in the Theory of Computation group, where I studied under Silvio Micali. After graduating (1991) I worked at IBM as a security architect, then came to UCD (1994), where I’ve been a professor ever since. Still, for a long time I managed to split my time about equally between the USA and Thailand. My research has focused on obtaining provably good solutions to protocol problems of utility to people’s privacy and security. I’ve been lucky enough to get some nice recognition for this work, including the Levchin prize (2016), PET Award (2015), IACR Fellow (2012), ACM Paris Kanellakis Award (2009), and the RSA Award in Mathematics (2003).

In recent years I grew increasingly skeptical of the claimed benefits of CS, which routinely seem dwarfed by the harms we help cause. Correspondingly, I shifted much of my attention to social and ethical issues connected to technology, especially the climate crisis and the problem of mass surveillance. I shifted much of my university teaching to ethics (especially course ECS 188). I support social justice and environmental movements, including JVP and XR. I retired from UCD in July of 2024, spending my last term teaching a course on cryptography and an experimental course on Black Mirror. I am sad to leave UCD, and would like to continue teaching, but my views had drifted from those of my peers to the point that it felt uncomfortable to continue where I was. At the same time, I had aged to where I could retire, if I was no longer where I belonged.

Personal information: my wife is Bongkotrattana Lailert. She goes by Kot (say goat quickly and with a low tone of voice). My son Banlu, age 14, loves rock climbing. He competes, too. For the last few years, I split my time between Davis, California and Portland, Oregon. My sister, Jodi Walder, also lives in Portland. She is amazing at helping students navigate college admissions. After saying my goodbyes to UCD, my family and I may split our time between Canada (BC), Thailand (Phuket, Phrae), and the USA (California, Oregon).
