Donella Beckwith, Ph.D.

Research Interests

• Elucidating structure-activity relationships (SARs) and binding interactions of protein-ligand/small molecules harnessing evaluative methods like flow cytometry, fluorescence-activated cell sorting (FACs), fluorescence polarization (FP), enzyme-linked immunoassays (ELISA), and fluorescence intensity (FLINT) binding assays
• Uncovering thermodynamic and kinetic biophysical protein-ligand/small molecule interactions employing isothermal titration calorimetry (ITC), KinITC, and surface plasmon resonance (SPR)
• Gaining molecular level insight into the energy landscapes governing recognition of protein-ligand/small molecule complexes utilizing atomic force microscopy (AFM) based on dynamic single-molecule force spectroscopy (SMFS)
