I am the Dean of the School of Information, University of Michigan. As an academic, I am the Arthur W. Burks Professor of Information and Computer Science, and a Professor of Economics and Public Policy. I was also the founding Director of STIET (a research program for Socio-Technical Infrastructure for Electronic Transactions) at Michigan, but when I moved into deaning I turned over the Directorship to my colleague, Prof. Yan Chen.
My research and teaching are a mix of mostly economics with some computer science, and a bit of psychology (cognitive, and increasingly social), addressing principles of design and performance for information technologies and digital information content. Recently I started to focus on incentive-centered design -- design of information systems and services that takes into account the behavior of autonomous, motivated and often strategic humans. I also do a fair bit of work on competition policy and antitrust, especially for technology-related industries. In the past I have worked on taxation and corporate behavior, and public utility pricing.
The advent of the web has led to a recent explosion in bibliometrics to measure scholarly impact. I obtained the following calculations for "MacKie-Mason" on 31 Jan 2015:
I have started curating my online scholarly presence through Google Scholar Citations: http://scholar.google.com/citations?user=Hd3kUc4AAAAJ
Notes: The h and i10 index are calculated by Google using Google Scholar Citations. See Reflections on Google Scholar on using this source for scholarly bibliometrics. My Erdős number is achieved through the following sequence of co-authorship links: Erdős -> Daniel J. Kleitman -> Rakesh Vinay Vohra -> Michael P. Wellman. (I also have a completely different 5-path: Erdős -> George Piranian -> Charles Titus -> Carl Simon -> Ted Bergstrom.) The number of my publications provided by Google Scholar Citations is high because I have not found a way to merge all publications that are the same but appear in citations with variant names (Google Scholar Citations seems to limit merges to papers that appear on the same screen, with a maximum of 100 per screen).
