Meet the CSSI 2015 Professors
Professors - Session A
Jennifer Wolff is a developmental biologist interested in the embryonic development of the nervous system. She is currently using genetic and molecular approaches to investigate how male-specific neurons that influence mating arise during development in the model organism C. elegans. She teaches Animal Developmental Biology, Developmental Neurobiology, Genetics, and Introductory Biology.
Professor Wolff is the Director for CSSI Session A.
Joe Chihade received his Ph.D. from Columbia University in 1996. He is a biochemist who studies protein-RNA interactions. For the past several years, his research has focused on understanding how human mitochondrial transfer RNAs are recognized by enzymes in the process of translating the genetic code. Joe teaches organic and biological chemistry and is the director of the Biochemistry program.
Stephan Zweifel earned his B.S. in Biology from the University of California-Davis, and his Ph.D. in molecular genetics from the University of Washington in Seattle. A geneticist and molecular biologist, his research focuses on identifying and characterizing the nuclear genes responsible for the proper transmission of the mitochondrial genome. Stephan has also recently begun using DNA fingerprinting techniques to analyze the population dynamics of a variety of threatened reptile species. His teaching duties in the Biology Department include: Introductory Biology, Genetics, Molecular Biology, and a seminar on Behavioral Genetics.
Ryan Steed earned his Ph.D. in biochemistry from the University of Wisconsin-Madison. In the laboratory, he studies how molecular machines at the boundaries of cells are powered by electrochemical gradients across the cell membrane. Of particular interest is the mechanism of the proton-powered ATP synthase, responsible for converting the energy of the gradient into the chemical energy currency of the cell, ATP. Ryan teaches introductory chemistry, biochemistry, and biophysical chemistry.
Professors - Session B
Cameron Davidson received his Ph.D. in geology from Princeton University in 1991. He is a structural petrologist interested in the processes of continental growth and the exhumation history of deep crustal rocks during mountain building. He is also interested in energy use, natural resources, and climate change. Cam currently teaches Introduction to Geology, Mineralogy, Petrology, and The Geology of Energy and Mineral Resources at Carleton College. Learn more about Cam Davidson.
Professor Davidson is the Director for CSSI Session B.
Will Hollingsworth earned his Ph.D. in chemistry at the University of California at Berkeley in 1982. He is a physical chemist whose research interests involve a laser-based form of spectroscopy that shoots an intense focused visible beam at gas-phase molecules and picks up the pieces after the molecule falls apart. He regularly teaches environmental chemistry, quantum mechanics and spectroscopy in the chemistry department and sometimes gets out to teach a class for environmental studies.
Andrea Kalis earned her B.S. in Marine Biology from Eckerd College in 2003, and her Ph.D. in Molecular, Cellular, Developmental Biology and Genetics from the University of Minnesota in 2010. A developmental biologist, she uses genetic and molecular techniques to study sexually dimorphic development in the nematode C. elegans. Her current research focuses on the genetic mechanisms that control sex-specific development of neurons in C. elegans and how the highly conserved Hox genes are involved in this process. Andrea is a visiting professor of biology at Carleton College and teaches Evolutionary Developmental Biology and Introduction to Biology labs.
