Fall 2002 Teaching Assistant, Department of
Microbiology, Iowa State University, Introduction to Microbiology. Instructor: Dr. E. Braun. 2 credits, 2
contact hours per week for semester (152 students). Graded assignments and projects, prepared and delivered
two lectures. Spring 2000, 2001 and 2002 Teaching Assistant, Department of Microbiology, Iowa State University, Techniques in Molecular Biology Laboratory. Instructor: Dr. G. Beattie. 1 credit, 8 contact hours per week for 5 weeks (11 to 27 students). Contributed to course development, performed preparatory experiments, prepared solutions and cultures, and graded exams and assignments. Fall 1997 to Present Graduate
Research Assistant, Department of Microbiology, Iowa State University. Major
Professor: Dr. G. Beattie. Project: to construct and characterize a water
deprivation-responsive bacterial biosensor, to determine the spatial
distribution of the bacterial cells that were exposed to water deprivation on
leaves under various environmental conditions, to quantify the level of water
deprivation sensed by bacteria on leaves under various environmental
conditions. Supervised research
projects of several undergraduate students. Fall 1997 and Spring 1998 Teaching Assistant, Department of Microbiology, Iowa State University, General Microbiology Laboratory. Instructors: Drs. D. Bazylinski and L. Halverson. 2 credits, 8 contact hours per week (30 students). Prepared and presented all lectures, prepared and graded exams, performed preparatory experiments, and prepared microbial cultures. Fall 1995 to Spring 1997 Graduate Research Assistant, Environmental Science, University of Northern Iowa. Major Professor: Dr. J. Bumpus. Assisted with Microbiology lab (Fall 1995) Project: examined the ability of two white rot fungi grown on a spent industrial product to degrade three explosives, TNT, HMX and RDX, into non-toxic intermediates and, eventually, carbon dioxide both in the laboratory and field (Yorktown Naval Base, VA). May 1993 to August 1995 Physical Science Technician, US Fish & Wildlife Service, National Fisheries Research Center, La Crosse, WI. Supervisor: Dr. G. Stehly. Duties: assisted with laboratory work on benzocaine approval by the FDA, completed poster and slide presentations for supervisors, data entry, prepared a database of articles in ProCite and budget work. |
