Research projects: Knowledge of the pKa value and thus the protonation state of small molecules is crucial in drug discovery, as it influences both pharmacodynamic and pharmacokinetic aspects. Similarly, the protonation state of proteins (macroscopically and microscopically with respect to individual amino acid residues) is a key issue given its significant impact on molecular recognition properties. To elucidate possible pKa value shifts and protonation effects that occur during the binding process between proteins and small molecules (or fragments), I use wet lab techniques (in particular isothermal titration calorimetry, protein crystallography) together with in silico methods (such as Poisson-Boltzmann/Free Energy perturbation calculations) for several target proteins, including endothiapepsin, human carbonic anhydrase II, and protein kinase A.
