Agata Rekas staff profile

Profile

Agata is working as a Protein Chemist with the National Deuteration Facility, responsible for protein deuteration and characterization. As a biologist, she has experience in biochemistry and cell biology research, including several years of using NMR in cell biology, medicine and protein biochemistry.  She used NMR, X-ray crystallography, and more recently small-angle scattering techniques for structural and functional characterization of proteins.  Her research interests involve the role of macromolecules in human conformational diseases, and their prevention.
