I enjoy a number of activities in addition to my professional work. Among these are aikido, linguistics, and sailing. I hold a sandan (3rd degree black belt) in aikido and I teach at the Maryland Ki Society in Olney Maryland.

I program in R, SPlus, SAS, Access, and Excel. I have created a website using HTML and ASP. In addition to English, I speak French and Hebrew, I understand some Spanish and German. I am studying Japanese.

I am a longtime sailor, and I own a 2003 ComPac 35 sloop. My wife and I sail her primarily in Chesapeake Bay. In the fall of 2007 and again in 2010 we travelled down the IntraCoastal Waterway to Florida on our boat. We live and work aboard in the winter and we return to Chesapeake Bay in the spring. In the spring of 2011 we cruised her to the Bahamas. We are not new to ocean sailing. We joined our son, Brian in Tahiti in July 2000 during his South Pacific cruise and accompanied him as far as Tonga (1500 miles).

I have served as a referee for the National Academy of Sciences/National Research Council and for the journal Statistics in Biopharmaceutical Research. I have contributed to a Wikipedia article.

I am currently mentoring two junior statisticians.
