Boulder Computer Architecture Research Lab

Tamara Silbergleit Lehman is an assistant professor at the University of Colorado Boulder in the Electrical, Computer and Energy Engineering Department. She also holds a courtesy appointment in the Computer Science department and she is a member of the Colorado Research Center for Democracy and Technology. Her work focuses on all aspects of computer security from the hardware perspective. Her research interests span a wide array of topics on the intersection of computer architecture and security.  Before doing her PhD, she completed an Masters of Engineering degree at Duke University in the Electrical and Computer Engineering Department and a Bachelor of Science from the University of Florida in Industrial and Systems Engineering. She is passionate about computer architecture, and her industrial engineering background gives her a new perspective on ways to optimize systems. She also enjoys working on the security space because it is one of the most challenging problems facing the computer industry. At the heart of most computer security challenges is people. Computers do what they are designed to do, but it is the people who re-define the system’s functionality. She strongly believes that secure systems should not rely on people writing correct code, or running well-intended applications, but instead having well defined functionality with well defined side-effects. In addition, her research is guided by the principle that all computers should be secure and efficient. Systems should not have to sacrifice efficiency for security.
