Professor

Our laboratory uses a combination of structural biology and biophysical techniques to discover how ion channels and membrane-embedded enzymes function at the atomic level. The proteins we study are crucial for the function of the immune system, vision, cell differentiation, and embryonic development, and they are potential targets for diseases including immune disorders and cancer. Our discoveries lead to new understandings of the fundamental mechanisms of the ion channels and enzymes. These understandings also guide our efforts to develop and evaluate small molecule and biologic modulators for therapeutic potential for cancer and other diseases.

Disclosures

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.

Stephen B. Long discloses the following relationships and financial interests:
