RESEARCH INTERESTS

My research interests include glacial hydrology and Quaternary geology. With respect to glacial
hydrology I am involved in defining the origin and pathway of subglacial discharge
associated with temperate glaciers. This generally involves quantifying discharge from
the terminus of a glacier and separating flow components using isotopic characteristics of the
discharge. My interests in Quaternary geology include sedimentology of glaciogenic deposits
that occur along the margin of modern glaciers as well as those left behind by icesheets that once
covered the Great Lakes basin. This often includes studying the micromorphology of the deposits.
Current projects involve working at the Matanuska Glacier
in southern Alaska with a team of researchers from Lehigh University, Penn State University,
Augustana College and the U.S. Army Cold Regions Research Laboratory. Of particular concern
to the team is the origin of basal ice and debris bands that occur near the glacier terminus. Also
of interest is defining flow components of meltwater discharge from the glacier and investigating
the micromorphologic characteristics of glaciogenic sediments near the glacier margin.
Current projects in Quaternary Geology include analysing large-scale glaciotectonic structures
that occur along the eastern shore of Lake Michigan, defining the sedimentology of mega
crevasse fillings at Sleeping Bear Dunes National Lake Shore in northwestern lower
Michigan, and relating burial of the Lake Gribben Forest in central northern Michigan to
the Younger Dryas event of Northern Europe.
Funding to support the above research comes from grants awarded by the National Science
Foundation, U.S. Geological Survey State Map and Edmap Programs, and U.S. Army Cold
Regions Research Laboratory.
