Research Interests

Dr. Winter's research interests are in the Organic and Bioorganic Chemistry of naturally occurring substances. Emphasis is on the isolation, structure determination and chemical interconversion of natural products of biological interest. He also has major interests in the application of mass spectrometry for characterization and structure determination and collaborates with faculty colleagues on those problems related to their research which are amenable to mass spectral measurements.
