"There are 10^11 stars in the galaxy. That used to be a huge number. But it's only a hundred billion. It's less than the national deficit! We used to call them astronomical numbers. Now we should call them economical numbers." - Richard Feynman, physicist, Nobel laureate (1918-1988)

david_reileyWho Am I?

I am passionate about the use of field experiments in economics and the social sciences, and I have spent my career promoting their use. Before my dissertation at MIT in 1996, field experiments were quite rare in economics. Now there are dozens of people regularly performing field experiments to learn about economic and social behavior. Most people still consider economics to be an observational rather than an experimental science, but that has been changing significantly.

I have developed a course on field experiments for the master's program in data science at the UC Berkeley School of Information, with the course offered for the first time in Fall 2014.

I am an economist in the advertising-science group at Pandora and an Adjunct Professor at the UC Berkeley School of Information. I previously spent more than seven years at Google and Yahoo! Research, primarily working on experiments to measure the effects of online advertising.

In 2010, I settled in Berkeley, California, with my wife Jill Sazama. I am finally feeling a bit settled in the Bay Area, after several years of transition between my former home in Tucson and my new home in California.  I am finally feeling a settled in the Bay Area, after several years of transition from my former home in Tucson, and several years of inconvenient commuting to Silicon Valley from Berkeley. I enjoy being able to take public transit to Pandora in Oakland, along with a nice, long, hilly walk between my house and the BART station. I'm getting much more exercise than I used to.

I am also proud to serve as the president of the PGSS Alumni Association. The Pennsylvania Governor's School for the Sciences was one of the best experiences of my life, but the school died in 2009 in state budget cuts. I have been organizing the 2400 alumni of the school from 1982-2008 to try to get the school resurrected. I have been passionate about education for years, and this is the only educational institution I've ever been involved with where all the students wanted to learn and all the teachers wanted to teach. The demise of this school was a terrible loss, so I am pleased to have played a role in bringing it back.  I am very pleased to report that PGSS has returned to Carnegie Mellon University as of summer 2013!
