My lab studies the conformation-biological activity relationships in peptides/proteins that inhibit cancer growth, such as cutaneous squamous cell carcinoma and glioblastoma. We also examine the description of solution structure of polypeptides by Molecular Dynamics simulations and vibrational and/or electronic circular dichroism spectropolarimetry and the effects of weakly polar interactions on peptide/protein structures.
