FT 2008: The 11th International Conference on Thermochronology (FT2008) convened in Anchorage from 12-19 September, 2008. The meeting had 140 participants, and involved 50 oral presentations and 70 poster presentations. Aside from photos and the general schedule of the meeting, this link will take you to the PDF download of the extended abstracts from that meeting FT2008 - Alaska

DAM CONCERNED: My work on Dam Safety and flooding in the Schoharie River is done though the Dam Concerned Citizens, Inc.

GET OUT THERE: We teach a number of Field courses at Union College which allow students to see and study rocks and sediment in natural settings.

MINITERM: Living on the Edge is a Union College Miniterm aimed at exposing students to geologic hazards and the way society mitigates them. A PDF of a Union College Magazine article about this experience is here (3.1 Mb).


Teaching the Geosciences in a Research-rich environment

My research is focused on low-temperature thermochronology and Cordilleran tectonics, flood hazards and watershed analysis, and the sediment record of environmental change. Much of my work with detrital zircon is aimed at a better understanding of radiation damage and how this affects geochronology.

My teaching is based on active learning in a research-like environment. I teach courses in Natural Disasters, Sedimentation and Stratgraphy, Tectonics, and Structural Geology. I am a Fellow and active member of the Geological Society of America.


Union Fission Track Lab

The Union Fission track Lab at Union College is one of the leading labs in the analysis of fission track in zircon, or at least we think so. We do traditional fission track studies to understand orogenic development, thermal studies related to fluids and ore forming events, and low-temperature studies in the analysis of basin maturation. A significnat fraction of our work involves understanding radiation damage in zircon. More...

Keck Geology Consortium

The Keck Geology is a multi-college collaboration focused on enriching undergraduate education through development of high-quality research experiences in the Geosciences. The Consortium has been a fundamental component of the undergraduate-research landscape since inaugural projects in 1987. Here at Union we are proud to be part of the Consortium and we are actively involved in running projects and mentoring students. The Keck Consortium and the research project that we run has been named one of seven "Programs that Work" by Project Kaleidoscope. In 2007 I co-led a project called Rocks and Rain in the Swiss Alps.

Alaska - the evolution of the Chugach-Prince William flysch

This multi-year project is focused on understanding the tectonic evolution of the Chugach-Prince William terrane in south central Alaska. This overall effort has been co-funded by the Keck Consortium and by the National Science Foundation. The focus of our effort is on the very thick rocks of the CPW terrane that were intruded by near trench plutons and then translated some controversial distance along the North American margin in the early Tertiary. I am co-leading a project with Cam Davison of Carleton College. Details of the our multi-year effort in southern Alaska is at this web page.

Mohawk Watershed

For a number of years we have been looking into flooding on the Mohawk River in upstate New York (USA). In doing so, we've been primarily focussed on understanding the conditions that surround historic floods so that we can better understand future hazards for the city of Schenectady and nearby communities. We've compiled a relatively long record of historical floods through a variety of archives, and we've studied ice jams and the dynamics of these ice jams. Some of our recent work has been focussed on determining the movement hisotry of landslides in the basin. The Fifth Mohawk Watershed Symposium  is in March More...


I find teaching fascinating and I enjoy getting students excited about science. I teach a number of field-intensive courses where students make observations, collect data, and then interpret those data in a meaningful way. I teach Sedimentology and stratigraphyStructural geologyEarth and life through time, and Geologic Hazards. Most course information is posted internally (Moodle). On an irregular basis I teach Carbonate Sedimentology,and Living on the Edge and other FIELD Programs. I have several videos that illustrate Geologic Processes (at YouTube), including analog models for the development of orogenic wedges that are made in our sandbox.
