Postdoctoral position in ambient-pressure XPS/STM
A Postdoctoral Scholar position with a background in Chemical Engineering, Materials Science, Chemistry, or Physics is available in the School of Chemical, Biological and Environmental Engineering (CBEE) at Oregon State University under the direction of Prof. Gregory Herman. Candidates must have significant experience with X-ray photoelectron spectroscopy (XPS) and scanning tunneling microscopy (STM).

The ideal candidate will have a demonstrated track record of scholarship, including several first-author publications, presentations at scientific conferences, and strong project management skills. The candidate will study the surface and interface properties of materials using ambient pressure XPS and STM. Projects include single atom catalysis, surface corrosion, and electronic materials/devices. Preference will be given to candidates who have experience with ambient pressure techniques (AP-XPS and/or AP-STM) and will contribute to the educational and research mission of CBEE and OSU.

Further information regarding the research in Prof. Herman’s group, research capabilities, and postdoctoral positions at Oregon State University can be found at, and, respectively.

Candidates must have completed their doctoral defense and be able to start as soon as possible. To apply please send a single pdf file containing a cover letter, curriculum vitae, and the names of three references to
