Denis Foo Kune, Ph.D.

I am a scientist, researcher and founder.  I focus on security.  I launched the cyber-security startup Virta Laboratories with my two co-founders, Ben Ransford and Kevin Fu.  In the past few years, I have been working on clinical systems, medical devices, and side-channel analysis.  Prior to that, I was working on cellular networks and internet routing.

I did my postdoc at the University of Michigan with Kevin Fu. I received my Ph.D. from the University of Minnesota while working with Nick Hopper and Yongdae Kim. My thesis focused on improving security on the wireless medium. I looked at electromagnetic interference attacks on time-varying voltage sensors and vulnerabilities on wireless WAN protocols.

In my spare time, I kiteboard.
