Two Ph.D. Student Assistantships Carbon-Mineral Biogeochemistry of Earthworm Invasion.
University of Delaware We seek two highly motivated candidates with M.S. or equivalent research experience to join our USDA National Research Initiative funded project entitled "Acceleration of inorganic nutrient release and mineral-organic matter association by biophysical soil mixing along an earthworm invasion chronosequence." This project aims at quantitatively coupling the ecology of earthworm invasion with two major terrestrial biogeochemical processes: mineral chemical weathering and carbon cycling, in which soil bioturbation is considered as a bridging mechanism. The project has intensive field, laboratory, and modeling components. The field site is located in the Chippewa National Forest in Minnesota. Accepted students will be mentored by an interdisciplinary team of scientists Kyungsoo Yoo at University of Delaware (soil geochemistry and geomorphology, http://copland.udel.edu/~kyoo/), Anthony Aufdenkampe at UD and Stroud Water Research Center (organic and isotope geochemistry,http://www.stroudcenter.org/about/aufdenkampe.htm), and Cindy Hale at the University of Minnesota, Duluth (ecosystem ecology, http://cfhe.cfans.umn.edu/people/hale.html). Stipend and tuition waiver are available as early as February 2009. Degrees will be granted by the University of Delaware's Dept. of Plant and Soil Sciences (http://ag.udel.edu/plsc/). Reflecting the mission of UD's new Center for Critical Zone Research(http://cczr.dbi.udel.edu), coursework toward degrees will be completely customized to meet the needs of individual students in this multidisciplinary project and will draw from the extensive offerings within UD's College of Agriculture and Natural Resources (http://ag.udel.edu), UD's College of Marine and Earth Studies (http://www.ocean.udel.edu), and UD's College of Arts and Sciences. State-of-art laboratory facilities are available for this study at the UD (http://cczr.dbi.udel.edu/resources.php) and the Stroud Water Research Center (http://www.stroudcenter.org). Applicants should have a academic background in a field of earth, environmental, or ecological science and preferably some coursework in biogeochemistry or soil science. Applicants should also have experience in more than one of the followings: fieldwork, geochemical laboratory analyses, computer modeling, scientific presentations and writing. We seek students who could start fieldwork in summer 2009 at the latest, with possibilities to start coursework as soon as February 2009. We encourage interested students to email as soon as possible Kyungsoo Yoo ([EMAIL PROTECTED]) and Anthony Aufdenkampe ([EMAIL PROTECTED]) for further details while preparing a CV, statement of academic interest, and contact information of two references. Official applications should be made to UD's Graduate Office (http://www.udel.edu/gradoffice/applicants/) by Dec. 1 2008 for Spring 2009 admission and April 1, 2009 for Summer 2009 admission. -- Kyungsoo Yoo Assistant Professor University of Delaware Plant and Soil Sciences Dept.
