POSTDOCTORAL POSITION IN BIOMEDICAL PHYSICS/BIOMEDICAL ENGINEERING
Vanderbilt University and Vanderbilt University Medical Center invite applications for a postdoctoral position in the Department of Surgery, in a collaborative effort with the Vanderbilt Institute of Integrative Biomedical Research and Education, to develop novel techniques for recording and characterizing the magnetogastrogram and magnetoenterogram (biomagnetic fields of the stom¬ach and small bowel). The Vanderbilt University GastroIntestinal SQUID Technology (VU-GIST) Laboratory, a joint effort between Vanderbilt’s Departments of Surgery, Physics and Biomedical Engineering, has produced award-winning research at the boundary of medicine, physics and bioengineering. A recent PhD in physics or biomedical engineering is required. Experience in signal conditioning and processing and/or cryogenic tech¬niques related to SQUID magnetometers is desired. Experience with MATLAB and LabVIEW is also preferred. The successful candidate will be involved in all phases of research from experiment planning and conduct to data collection and analysis and publication. Salary commensurate with experience.

Vanderbilt University and Vanderbilt University Medical Center invite applications for a postdoctoral position in the Department of Surgery, in a collaborative effort with the Vanderbilt Institute of Integrative Biomedical Research and Education, to develop novel techniques for recording and characterizing the magnetogastrogram and magnetoenterogram (biomagnetic fields of the stom¬ach and small bowel). The Vanderbilt University GastroIntestinal SQUID Technology (VU-GIST) Laboratory, a joint effort between Vanderbilt’s Departments of Surgery, Physics and Biomedical Engineering, has produced award-winning research at the boundary of medicine, physics and bioengineering. A recent PhD in physics or biomedical engineering is required. Experience in signal conditioning and processing and/or cryogenic tech¬niques related to SQUID magnetometers is desired. Experience with MATLAB and LabVIEW is also preferred. The successful candidate will be involved in all phases of research from experiment planning and conduct to data collection and analysis and publication. Salary commensurate with experience.
