Testimony California State Assembly Assembly Select Committee on Ports

I am the Paul E. Holden Professor of Management Science at the Graduate School of Business, Stanford University. Since September 11, 2001, I have used mathematics to analyze a variety of homeland security problems in bioterrorism (effective responses to terrorist attacks using smallpox, anthrax or botulinum toxin) and in border security (identifying ways to improve the biometric aspects of the US-VISIT Program and the detention and removal operations of the Bureau of Immigration and Customs Enforcement). These analyses have led to policy recommendations, several of which the U.S. Government have adopted.
