University of Texas Navigation

I am an assistant professor in the Graduate Program in Operations Research and Industrial Engineering (ORIE), which is within the Department of Mechanical Engineering, at The University of Texas at Austin (CV).  I also hold a courtesy appointment in the Department of Petroleum and Geosystems Engineering (PGE). In addition to these appointments, I am a fellow in the Center for International Energy and Environmental Policy (CIEEP) and the Center for Petroleum Asset Risk Management (CPARM). I hold MS and PhD degrees in Engineering-Economic Systems from Stanford University. Before returning to academia, I was a senior engagement manager and co-director of client education for Strategic Decisions Group.

My research and teaching interests are broadly focused in the area of decision making under uncertainty. My primary application area is in the energy arena. I am Chair of RPSEA's (a DOE program) Ultra-deepwater Environmental, Safety, and Regulatory Technical Advisory Committee. My research has been funded by the NSF, DOE, NETL, and private companies. In 2009, I was fortunate enough to be awarded an NSF CAREER grant. My work has been featured in the New York Times, The Wall Street Journal, the Financial Times, Bloomberg, National Public Radio, and in dozens of local and regional media sources. In addition, this work is featured in the documentary Cool It. This work was part of the Copenhagen Consensus on Climate Project and was selected by a panel of economists, including four Nobel Laureates, as the best response to climate change.

Baseball Research
You may have seen my research referenced by Evan Gattis (Atlanta Braves) in the June 10, 2013, edition of Sports Illustrated.

If you are interested in decision making and baseball, watch this webinar I gave as part of Stanford's Strategic Decision and Risk Management program.

Back in 1994-1995, while in graduate school, I developed a pitch/hit charting software program called ChartMine. ChartMine was used by over 300 colleges, including one-third of Division 1 programs, and ESPN. As part of this effort, I wrote several white papers regarding baseball statistics and strategy. I still receive emails asking for this work, so I am posting a few of the papers below.

The Weather Channel Research
Do you watch The Weather Channel and wonder how accurate their precipitation forecasts are? This paper summarizes my study of over 13 million precipitation forecasts. You can use the tables I include below to convert The Weather Channel's precipitation forecasts into observed frequencies. To use the tables you simply look up the forecasted probability of precipitation (PoP) given by The Weather Channel on the horizontal axis and then read down the rows to adjust for the length of forecast. For example, a 5-day lead-time is a forecast for 5 days from today.
