Dr. Peter Schuck is the acting chief of the Protein Biophysics department in the National Institute of Health's Division of Bioengineering and Physical Science. His current research work is on protein structure and function, with studies in multi-protein complexes, membrane proteins in detergent solution, self-assembling and filamenting proteins, structural and nonstructural viral proteins, homogeneous and heterogeneous interactions of immunological cell surface receptors; and biophysical methods and instrumentation through analytical ultracentrifugation, optical biosensors, static and dynamic light scattering, calorimetry, and circular dichroism.
