Rachel Greenstadt

I am an Assistant Professor of Computer Science at Drexel University. where I research the privacy and security properties of multi-agent systems and the economics of electronic privacy and information security. I run the Privacy, Security, and Automation Laboratory (PSAL). I'm currently teaching CS 475: Computer and Network Security. In Spring 2009, I will teach a seminar. In fall 2008 I taught a gradute level course: CS 510: Introduction to Artificial Intelligence.

Employment Experience

• Harvard Computer Science Network Laboratory, Research Assistant, (Summer 2002), I work with Professor H.T. Kung on security analysis and design of an IP-layer anonymizing infrastructure.
• MIT Lab for Computer Science, Research Assistant, (Summer 2001) I worked with Kevin Fu, Frans Kaashoek and the Cookie Eaters Group on the cookie collection project. I built a web proxy to collect ephemeral cookies, researched collecting cookies transmitted using SSL and wrote web based materials to explain client authentication on the web.
• Mitsubishi Electronics Research Lab, Research Intern, (Summer-Fall 2000) I worked with Dr. Carol Strohecker on human computer interaction research. My work focused on redesiging the Software Construction Kits for learning. In particular, I revised and reworked the Bones kit for use in the Museum of Science. This kit allows a user to create a creature and then animate it.
• Litton Guidance and Control Systems, Intern, (Summers 1999, 1998) I worked on programming, debugging and building simulators for helicopter control systems in Java, Ada and C. I also performed unit testing and wrote documentation. I designed and produced slides of the system for a presentation to the government of New Zealand.
