Catherine L Jahncke, Hayward Associate Professor of Physics at St. Lawrence University, received her Ph.D. from North Carolina State University and her B.S. from Auburn University. Her research interests are in optics and optical properties of materials. She uses techniques such as Raman spectroscopy, ellipsometery, and near-field scanning optical microscopy to characterize materials. Her current research projects include the following: the size effect on the properties of barium titanate, a piezoelectric and birefringent material with many applications including super capacitors; the polarization properties of nacre (a collaboration with Dr Galvez and Metzler at Colgate); and heterobimetallic compounds, materials with applications in artificial photosynthesis (a collaboration with Adam Hill in Chemistry at SLU).
Dr. Jahncke usually teaches the junior level lab courses: instrumentation lab and electronics.

- Dr. Jahncke's research interests are in optics and optical properties of materials. She uses techniques such as Raman spectroscopy, ellipsometery, and near-field scanning optical microscopy to characterize materials. Recently she has been collaborating with Dr. Adam Hill in the Chemistry Department where she uses Raman spectroscopy to characterize heterobimetallic materials made in Dr. Hill's group. These materials can be used as an alternative fuel source since they can perform artificial photosynthesis. They take energy from the sun and use it to break down carbon dioxide into products that can be converted into chemical fuels.
