Group Members

I currently have two postdoctoral positions open in my research group, in the area of fiber optic sensors and SiC sensors and electronics.
Postdocs:
	Peter Tobias received a M. Sc. degree in physics, from RWTH Aachen, Germany, in 1993, and a Ph.D. degree in applied physics from Linköping University, Sweden, in 1999. For his master’s thesis, he studied calorimetric gas sensors for explosive mixtures. His dissertation focused on sensors based on the field-effect in semiconductors, especially fast gas sensors for automotive exhaust. Since 2000 he has been a postdoctoral researcher at the Center for Sensor Materials at Michigan State University. He is interested in sensors and in surface science; his current research are silicon carbide based gas-sensitive devices. E-mail

Collaborators: D. J. Osborn is a graduate student in Prof. Gregory L. Baker's group in the Dept. of Chemistry at Michigan State University. His research involves synthesis of Mo₆Cl₁₂ and related compounds and immobilization of these cluster in sol-gel matrices for high temperature fiber optic sensor applications. E-Mail

SiC based Sensors and Electronics Postdoctoral Position Center for Sensor Materials and Dept. of Physics Michigan State University
Candidates are invited to apply for a postdoctoral position in wide bandgap semiconductor devices with the Center for Sensor Materials and the Dept. of Physics at Michigan State University. The research involves investigation of SiC devices for high temperature sensing and electronic applications. Our group is investigating the electronic, chemical and structural properties of SiC field-effect structures and their constituent interfaces in chemically reactive environments at elevated temperatures.
Candidates should have a Ph.D. in electrical engineering, condensed mater physics or materials science with a firm background in semiconductor device physics. Background should include electronic device and materials characterization techniques as well as hands on microfabrication experience. The position will involve significant interactions with our industrial collaborators. Applicants should send a curriculum vitae, statement of research interests, and names of three references to: Prof. Ruby N. Ghosh, Dept. of Physics, 2167 Bio-medical Physical Science Bldg., East Lansing, MI 48824-2320 or ghosh@pa.msu.edu or www.pa.msu.edu/people/ghosh. Michigan State University is an affirmative action/equal opportunity institution.

Fiber Optic Sensing Postdoctoral Position Dept. of Physics and Center for Sensor Materials Michigan State University
Candidates are invited to apply for a postdoctoral position in fiber optic sensing in the Dept of Physics at Michigan State University. The research involves development of a high temperature oxygen sensor based on the quenching of the luminescence from metal-halide clusters by 3O2. We are investigating the photophysics of these clusters immobilized in a porous sol-gel matrix as a function of temperature and gas composition, for real time oxygen sensing in power plants.
Candidates should have a Ph.D. in materials science, physical chemistry or optical physics. Experience in optics or optical fibers, materials characterization techniques and sensor development is preferred. The candidate will have the opportunity for significant interactions with our collaborators in U.S. national laboratories. Applicants should send a curriculum vitae, statement of research interests, and names of three references to: Prof. Ruby N. Ghosh, Dept. of Physics, 2167 Bio-medical Physical Science Bldg., East Lansing, MI 48824-2320 or ghosh@pa.msu.edu or www.pa.msu.edu/people/ghosh.
