Research

Experience:

June 2002 – June 2003:  Post-Doctoral Fellow in Environmental Soil Chemistry, worked with Professor D.G. Strawn, University of Idaho, Division of Soil Science, on a grant from the U.S. E.P.A.  We studied the cycling of Pb, Cd, and Zn in contaminated soils in the Coeur d’Alene River basin, using XRD, TEM, ICP-AES, and an Electron Microprobe to better understand the chemical residency and bioavailability of these toxic trace elements.

 

Fall 1998 – Spring 2002:  Research Assistant: Worked with Professor M.E. Gunter on a research grant from the U.S.G.S. characterizing the mineralogy of the Phosphoria Formation in southeastern Idaho.  As a result of phosphate mining in this deposit, naturally occurring selenium has been released into the environment, and now threatens the continuation of phosphate mining in Idaho.

 

Fall 1997 – Spring 1998:  Senior thesis, SEM-EDS analysis of plagioclase megacrysts from the Mt. Marcy anorthosite, Essex County, New York.

 

Field Experience

June 2002 – June 2003:  Field sampling in the Coeur d’Alene River basin, development of field techniques which prevent oxidation of samples in transport from the field to the laboratory.

 

Summer 1998:  Teaching assistant for the Hamilton College Geology Field Camp in central New York and the “Four Corners” region of the southwest. 

 

Fall 1996 – Spring 1998:  President Hamilton Outing Club.

 

Fall 1997:  Performed stream surveys for the Oneida County, NY Soil and Water Conservation District.

 

Summer 1997: Participated in the Hamilton College Geology Department’s Field Study in Iceland program.  Surveyed the unique geology of Iceland and studied the relationships between the geology and the culture of the island.

 

Summer 1997:  Participated in a one-week archaeological dig on Afognak Island in the Kodiak archipelago, Alaska.

 

Summer 1996:  Participated in the Hamilton College Geology Field Camp in central New York and the “Four Corners” region of the southwest

 

Awards                               

1998                Root Fellowship for graduate study in science

 

1997                Dixon-Rogers Fund Grant for student research in the geosciences

 

1997                Potter Fund Grant for student field research in geology
