The Division of Physics, Mathematics and Astronomy of the California Institute of Technology is considering postdoctoral appointments in physics and astronomy at the ranks of Postdoctoral Scholar, Senior Postdoctoral Scholar, and Senior Research Fellow. The term of initial appointment for a Postdoctoral Scholar or a Senior Postdoctoral Scholar is one year with the possibility of two one-year reappointments at the same rank. The term of initial appointment for a Senior Research Fellow is three years with the possibility of reappointment to a maximum of six years. All appointments are contingent upon completion of all requirements for a Ph.D.

Areas of research in which openings are expected include theoretical astrophysics and both theoretical and experimental research in the following fields: gravitational waves and gravitation physics, including the LIGO project; particle physics; nuclear physics; condensed matter physics; computational physics; quantum optics and quantum computation; biophysics and neurobiology; solar physics; space physics and cosmic-ray astrophysics; cosmic microwave background observations; ultraviolet and infrared astronomy; x-ray and gamma-ray astronomy; millimeter-wave interferometry; submillimeter-wave astronomy; observational radio and optical astronomy.

Applicants should write to the Chairman of the Division of Physics, Mathematics and Astronomy, Mail Code 103-33, California Institute of Technology, Pasadena, CA 91125, (or email nell@caltech.edu) providing curriculum vitae with email address, publication list, and list of references. The cover letter must state explicitly the area of interest and whether the applicant wishes to concentrate on theory or experiment.
