Radiochemical labeling of biomolecules, especially those that can be used to investigate biological and metabolic processes relevant to DOE goals in systems biology.
Investigating new approaches to simplifying radiochemical labeling of organic molecules, e.g. by using novel chemo-enzymatic methods for the radiolabeling of complex multifunctionalized biomolecules.
Autoradiographic and scintographic imaging of the movement and biodistribution of radiolabeled tracers, e.g. imaging transport of labeled sugars and signaling molecules in plants.
Radioligand binding assays and PET receptor occupancy studies.

30 Bell Avenue, Building 490
Upton, NY 11973-5000
One of ten national laboratories overseen and primarily funded by the Office of Science of the
U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical,
biomedical, and environmental sciences, as well as in energy technologies and national security.
Brookhaven Lab also builds and operates major scientific facilities available to university, industry
and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven
Science Associates, a limited-liability company founded by the Research Foundation for the State
University of New York on behalf of Stony Brook University, the largest academic user of Laboratory
facilities, and Battelle, a nonprofit applied science and technology organization.
