The principal interest of our group is to improve technology, strategies, and micro-methods for polypeptide isolation, mass spectrometric protein identification, and mapping of modified amino acids. The program draws from conventional biochemistry as well as from the fields of chemistry and engineering. These novel tools have found widespread use in the health and life sciences as a resource for the larger research community, and for our own studies on gene expression, proteomics of the human transcriptional machinery, protein modification profiling, and serum peptide diagnostics.

Doctors and faculty members often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community.

MSK requires doctors and faculty members to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public.

Paul Tempst discloses the following relationships and financial interests:
