Positions available

Postdoctoral Position
Metabolomics and Adductomics

Several postdoctoral positions available  for recent Ph.D. graduates interested in learning how to use mass spectrometry to investigate DNA modifications, repair, and DNA-protein interactions. We are supported by 4 NIH grants.  We recently purchased a high resolution Orbitrap QE instrument, in addition to existing triple quadrupole MS – it will be available for this work. We are located in a new beautiful Cancer Center building housing active investigators and core facilities including analytical biochemistry, genomics, and flow cytometry, all with state of the art equipment.

University of Minnesota has a very strong chemical biology, chemical carcinogenesis, and epigenetics community, and is an excellent environment for postdoctoral training. It does get cold in the winter, but we make the best of it by going skiing, ice skating, and enjoying the music and culture of the Twin cities. Summers are amazing, with many opportunities for outdoor recreation. Minneapolis is an extremely bike friendly city, and biking trails are amazing!

Postdoctoral position, Stephen S. Hecht laboratory

University of Minnesota

A postdoctoral position is available in the Hecht Laboratory for projects investigating mechanisms and prevention of cancer induced by tobacco products, e-cigarettes, and environmental carcinogens.  These projects, supported by grants from the National Cancer Institute, will determine the structures of metabolites and DNA addition products formed upon exposure to carcinogens found in tobacco products, e-cigarettes, and the general environment.   The laboratory uses state of the art mass spectrometry approaches and related highly sensitive analytical chemistry techniques to investigate metabolism and DNA adduct formation in exposed humans and laboratory animals.

Required qualifications:

A Ph.D. or equivalent degree in organic chemistry, biochemistry, analytical chemistry or a closely related field.  Familiarity with mass spectrometry and other highly sensitive chemical analytical techniques.

To apply, send your CV with the names of three references to Stephen S. Hecht  (
