**Post-Doctoral Research Associate available at Cornell University** The Department of Chemistry and Chemical Biology in collaboration with The School of Civil and Environmental Engineering at Cornell University solicits applications for a Post-Doctoral position that is currently available. This position involves spectroscopic research related to the development of methods for the visualization of the spatial distribution of toxic transition metals in microbial biofilms. The successful candidate will be responsible for the development of a novel laser based method for measurement of toxic transition metals within the structure of biofilms. The technique will employ fluorescent complexation agents to locate the metals in biofilms via fluorescence microscopy, using either one-or two-photon excitation. In addition, an electrochemical method will be developed to use micrometer sized ion-selective electrodes (ISE) modified with ligands with affinity for the metal ion under study. Applicants must have a doctoral degree in chemistry, spectroscopy, environmental or chemical engineering, microbiology, electrochemistry or some closely related area -- and a strong background related to the analysis of trace metals. Previous experience with microscopy, and laser techniques is desirable. Good written and oral communication skills are required. The position is available for one year, renewable by mutual agreement for a second year. Cornell University is an equal-opportunity, affirmative-action employer, committed to employing a highly qualified, diverse faculty and staff. Women and minorities are encouraged to apply. Applications will be accepted until the position is filled. Salary is $32,000/year. Please send your application letter, curriculum vitae, and the names, addresses (postal and email), and telephone numbers of three references to one of the following: Paul L. Houston Leonard W.
