About Me

I am a post-doctoral research fellow at the National Bureau of Economic Research, working with Shane Greenstein, Scott Stern, and Josh Lerner and finishing a PhD in Management Science at MIT.  My first advisor is Erik Brynjolfsson and second advisor is Scott Stern at MIT.  I had received a PhD in civil and environmental engineering from MIT in 1995.  Since then, I worked at a university, a research company, and a government research institute.  The last job I had before coming back to MIT for my second PhD was a senior engineer at Jet Propulsion Laboratory of NASA in Pasadena, CA.  I was a principal investigator, developing a sensor to detect a life form on Mars.  As I became more involved in managing an organization I belonged to as well as science and engineering projects, my research interest in the economics of technology grew: how information technology has changed the innovation.  I decided to pursue the second PhD at MIT again as Erik Brynjolfsson was a leading scholar in the economics of information technology.  Since then I have enjoyed learning the economics of science and technology.  In addition to learning the economics, I enjoy playing tennis.  My dream is to write a paper that a PhD seminar in the field of the economics of technology at any school would include and to attain the level of NTRP 4.0 in tennis.

Research

My first stream of research examines how information technology (IT) affects the diffusion of ideas using micro-level data.  As information technology has lowered the cost of publishing to almost zero, scholarly ideas diffuse through working papers, blogs, twitters, and many forms other than refereed journals.  Online open repositories of research articles such as arXiv.org and Social Science Research Network (SSRN) provide free access to unpublished and published manuscripts.  I assess the effect of free access, quality, early viewership, and various filters on the diffusion of scholarly ideas.  Another research focus examines how well firms collecting and using data for their business decisions perform and pay their top managers.  As we experience massive accumulations of digital data, firms leveraging the data perform and pay their top managers differently.  Using a survey of over 350 firms in different industries and instrument variables methods, I assess the effect of the data on firm performance and CEO pay.
