Director of Biophysics Resource Keck Laboratory
Biography
Ewa Folta-Stogniew has a PhD in Molecular Biophysics from Wesleyan University, Middletown, CT and MSc in Chemistry from Technical University of Wroclaw (Poland). She directs the Biophysics Resource of Keck Laboratory at Yale University School of Medicine, New Haven, CT. The resource provides a collaborative and non-collaborative support in applications of biophysical technologies. The projects supported by the resource elucidate protein structure-function relationship and concentrate on characterization of thermodynamics and kinetics of macromolecular interactions using light scattering, isothermal microcalorimetry, surface plasmon resonance and stopped-flow spectroscopy. Dr. Folta-Stogniew is an expert in application of light scattering for characterization of size and an association state of biological macromolecules in solution including native and modified proteins, nucleic acids, their macromolecular complexes and membrane proteins solubilized by detergents.
