Experience
2003-present. Biostatistical and epidemiological consultant, New York Methodist Hospital, New York
I teach a course to the Emergency Medicine and Surgical residents in basic epidemiology and statistics, and I consult on departmental research projects and maintain several of their study databases. I sit on the Institutial Review Committee as a guest member to review the statistics of proposed research. Helped in the preparation and submission of grants to the NIH and for-profit entities.
1998-present. Statistical consultant, Various companies
Build databases, provide analytic support and data analysis, create simple but informative graphics, teach small and large classes in statistics, critical thinking, use of software, write articles, and so forth.
Aug 2007-Dec 2007. Visiting Professor, Department Mathematics, Central Michigan University.
2003-Aug 2007. Faculty in Clinical Epidemiology, Weill Cornell Medical College, New York
2004-Aug 2007. Adjunct Assistant Professor of Statistical Science, Cornell University, Ithaca, New York
My research interests are prediction, diagnosis, and prognosis accuracy and usefulness; skill and cognitive biases in prediction; practical decision analysis; dynamical and ensemble forecasting; graphical data display; placebo statistics; induction; philosophical interpretations of statistics and probability; Bayesian foundations and the nature of evidence; Bayesian probability as it’s used in physics; and the adoption of Open Source software for publicly-funded clinical trials, particularly the development of the DrClamp web-based database. I teach courses in statistics, emphasizing both Bayesian and classical methods, and I consult and perform analysis on a wide array of clinical trials.
Assisted in the preparation and submission of many, many grants to various private and public institutions. I wrote the sample justification and data analysis plans plus co-wrote the methods sections. Became honorary Santa Claus mathematician (see main page).
2002-2003. Gotham Risk Management, New York
A start up then, after Enron’s shenanigans, a start down. We set future weather derivative and weather insurance contract prices that incorporated information from medium- and long-range weather and climate forecasts. A white paper is available on my web page.
1998-2002. DoubleClick, New York
I built an expensive and huge optimization engine for a web-based ad matching network, the details of which are terribly dull. Short version: click-through optimization, enormous database with about $10^8$ names, updated daily, clever modelling and scoring, all heavy-duty computational statistics.
1993-1998. Graduate student, Cornell University
Started studying of how long-range climate forecasts interacted with a crop model in the Atmospheric Science group, then switched to full time statistics. Was involved in the long-running environmental statistics consulting group, did work in tensor product splines and image analysis, then finished with practical decision analysis work. Was Vice Chair of the graduate student government.
1992-1993. National Weather Service, Sault Ste. Marie, MI
Forecast storms o’ the day and launched enormous balloons in the name of science. My proudest moment came when I was able to convince an ancient AT machine to talk to an analog (phone-coupled!) modem, all using {\tt BASIC}.
1992-1993. Sault Ste. Marie. Evening News
I wrote a free-lance science column for which I received free papers. And I was grateful for them.
1989-1992. Undergraduate student, Central Michigan University
Basic undergraduate meteorology degree, with an emphasis on dynamics and math. Started the local student meteorology group, which is now affliated with the AMS. Was involved with an FAA experiment of de-icing fluids. Spent a summer at U Michigan in a NSF REU program playing with a lidar used to model boundary layer dynamics. Won the Howard T. Orville scholarship from the AMS.
1983-1989. United States Air Force
Cryptography and other secret stuff. Shot things. I adopted and became proficient with fascinating and versatile military vocabulary. Ask me for examples. TS/SCI+ security clearance.
Activities
DrClamp, Ph.P. open-source project creator and leader. The primary purpose of Dr. Clamp is to have one place to manage and enter data, track patients, view reports, draw graphs, and analyze statistics. It was primarily designed for clinical trials, but it works for any patient/subject/person study where the data are best entered through a web page.
Monthly Weather Review: Associate Editor.
American Meteorological Society: Member of the Probability and Statistics Committee. Plan for short courses and regular meetings.
R. Development work on the verification package, which is maintained by Matt Pocernich at NCAR, who has done 99.9% of the work. I wrote the (outline of) skill function. Email for details.
Data Safety and Monitoring Boards and other similar activities. Current board member for a Columbia study involving medication adherence in hypertension patients.
Consultant—standard statistics consulting. Listed as a consultant on several pending grant submissions for studies at Columbia and New York Methodist Hospital.

Books
So You Think You’re Psychic?. This is a popular book written to slyly inculcate some skepticism into those who believe in the paranormal. I outline several experiments that anybody can do, then show how they can go wrong, how the statistics are misinterpreted, how normal explanations can mask as paranormal ones, and so on. I have a page for the book:
Or you can even buy it!
Stats 101. Who doesn’t love Statistics? You, almost certainly. Statistics classes are very badly taught, filled with useless memorization, time-wasting hand calculations, and boring examples. This book is my attempt to fix that. What you are downloading is a draft, not nearly complete; but there is enough meat to show you where I am going. Stay tuned to this page for updates.
