Please Post the following: We are searching for post-doctoral candidates to do interdisciplinary work at Columbia University in physical chemistry projects for two areas: basic studies of environmentally related surface chemistry on model metal oxide surfaces, and in the chemical physics of reaction dynamics on semiconductor surfaces. The candidates should have a strong experimental background in state-resolved laser techniques and/or in surface science. The work, which is focused by major new NSF centers in 1) environmental chemistry and 2) advanced material research, and would involve collaborative research among several research groups at Columbia. Please fax your resumes including the names of three senior faculty scientists familiar with your capabilities to Ms. Teresa Colaizzo at the Columbia Radiation Laboratory, 530 West 120th Street, rm. 1001, New York, NY 10027. Fax # 212-854-1909. Columbia University is an equal opportunity employer. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
