“I have heard all that you have to say to me on your problems. You ask me what to do about them. It is my view that your real problem is that you are a member of the human race. Face that one first.”
- Idries Shah

I have wide-ranging interests, and especially gravitate to interstices, where different ways of thinking come together.

Judgment and Decision-Making

My scholarly work has focused on general human judgment and decision making in health and medicine. I consider how physicians, patients, and policymakers form judgments and make decisions about health and health care — and how those decisions can be improved.

Recent projects include:

Making Medical Decisions: A Physician’s Guide. A book providing physicians with a practical translation of current theory and practice in medical decision making for use with their patients. Available from Cambridge University Press.
Life goals in health decisions. How do non-medical goals that may be achieved in the future impact the way people evaluate their health-related quality of life and make medical decisions?
Assessment of Evidence-Based Medicine Skills. How well do physicians learn to evaluate the validity of evidence from the clinical research literature, interpret results, and apply them to their patients? How can it be better taught, better learned, better practiced? What role should clinical librarians play? What are the implications for clinical behavior and patient outcomes?
Clinical values. What is the ideal physician, and how does the ideal differ for different patients? Are patients whose physicians share their ideals more satisfied with their physician and do they have better health outcomes?
Perceptions of and Attitudes toward Risk in Treatments. What aspects of treatment options or clinical trials cause people to consider them more or less risky? How much risk are people willing to accept?

Another interest is how organizational context (formal structure, informal norms, task design) affects decision-making and motivation in organizations. I have both descriptive and normative interests in this area.

Computer-mediated communication and information

I’m fascinated by the ways in which computer and network technology impact human communication and cognition.

Recent and past projects include:

Online teaching. Since 1998, I’ve been actively engaged in online teaching at the graduate level. A current interest is in developing network visualizations of online courses to assist teaching faculty.
Multi-user internet virtual worlds (MUDs). I spent 11 years (1995-2006) as the maintainer/developer of a flavor of MUD server called PennMUSH, and currently maintain the PennMUSH community site and produce Tinytalk, a podcast about text-based virtual worlds and their players. I have run MUSHes based on Frank Herbert’s book Dune (DuneMUSH) and Philip Jose Farmer’s Riverworld (Riverworld MUSH). I have also run a play-by-email storytelling game set in Riverworld. These “games” provide me a unique opportunity to study management and organization in a virtual environment, as well as being a lot of fun. I was a founding editor of the Journal of Mud Research (now the Journal of Virtual Environments) and published two papers in the area of organizational behavior and muds. More recently, I have been involved with some projects using MUSH servers as venues for art, both self-initiated and initiated by Nina Pope and Karen Guthrie, two professional UK artists.
Software development. Some past projects have included ebmlcs, testcalc, and other tools for teaching evidence-based medicine.
Unix/linux system administration. I’m an LPIC-2 certified linux system administrator. and co-author of the World Bank Information Technology Security Handbook for developing nations, published by infoDev. I’ve written a few technical articles, for Web Techniques magazine and ONLamp.com, and authored or co-authored four books published by O’Reilly Media, Inc: Managing Mailing Lists (1998), Stopping Spam (1998), Practical Unix and Internet Security, 3rd ed. (2003), and SpamAssassin (2004)
