Invited presentations/testimony to US government officials in multiple administrations including US Vice President, President’s Science Advisor, two Senate and six House Committees, various senators and representatives (and a Senator of France), travel to Greenland as speaker and resource expert with 10% of U.S. Senate, informal briefing of a larger group of senators, and briefings of additional cabinet-level officials. Inquiries from the press averaging daily; appeared frequently on television (BBC, Nova, etc.), radio (NPR, etc.), print (NYTimes, etc.); arguably one of the most active voices in translation of Earth sciences to the popular press. Formal reviews (papers, promotions, etc.) averaging 2/week; well over 1000 in total. Numerous and high-impact public presentations, almost 1200 in total. Well over 300 refereed publications (and over 60 additional publications including books and popularizations), most first-authored by me or advisees; listed as a “Highly Cited’’ researcher by ISI’s Web of Science (h=79, well over 22,000 citations) (higher numbers on Google Scholar). Main research contributions (personal, with students and post-docs): Provided key data and interpretations helping demonstrate that regional to global climate changes larger than any experienced by agricultural or industrial humans have occurred repeatedly, in decades to as little as a single year; helped reveal mechanisms and possibility of recurrence; Through data analysis and modeling of ice sheets and glaciers, helped understand ice-bed interactions with implications for flow changes affecting sea level with potential for large and rapid rise, and for interpretation of geological records, climatic changes and mountain-belt evolution; Contributed extensively to the toolbox for measurement of ice-core properties, and accurate and confident conversion to well-dated histories of temperature, accumulation rate, and other paleoclimatic variables. Experience: Ph.D., 1987, University of Wisconsin (Geology, Minor Materials Science); M.Sc. 1983, B.Sc. 1989 (With Honors, With Distinction, Summa cum Laude), Ohio State University (Geology and Mineralogy). Assistant Scientist, University of Wisconsin, 1987-1988; Assistant Professor (1988-1992), Associate Professor (1992-1994), Professor (1994-2000) and Evan Pugh University Professor (2000-), Department of Geosciences, Pennsylvania State University.
