Research Statement
Development of new techniques and approaches for determining the structure and dynamics of bioactive molecules. The four main areas of interest comprise:
(A) Development of methods for improving the accuracy of biomolecular structures determined by NMR data. Emphasis is on the development of better measurement techniques for interproton distances and dihedral angles from NOEs and J couplings, and development of a quantitative relation between molecular structure and chemical shifts/chemical shift anisotropy.
(B) Development of methods for characterizing 'long-range' intramolecular order by the measurement of dipolar couplings and rotational diffusion anisotropy. This addresses the main shortcoming of conventional NMR methods, which only provide strictly local structural constraints.
(C) Study of the relation between protein mobility and function by NMR methods.
(D) Development of techniques to extend the molecular weight limit of NMR structure determination.
