Jem Berkes

Research & Engineering

I work on a number of projects that aim to make computer systems more secure and reliable. Currently, I’m the principal investigator on our DDoS Defense project.


Jem founded his software business in 1999, and developed e-mail technologies as well as one of the first Unix tools to protect systems from viruses and malware. Jem created a variety of programs and network services to defend against emerging malware and botnet threats. He is the author of the popular grepcidr open source tool used by network administrators.

Before joining Galois, Jem was a Design Engineer at Altera Corp, where he worked on high-speed FPGA hardware, semiconductor modeling, and low-power optimization.

Jem received a BSc in Computer Engineering from the University of Manitoba and a MASc in Electrical and Computer Engineering from the University of Waterloo. As a member of Waterloo’s Centre for Applied Cryptographic Research, he investigated electromagnetic (EM) side-channel attacks against smart cards and other hardware.

He has experience in low-level software/hardware, assembly language, cryptography, protocols, and network-based security threats.
