Cancer Research Focus

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.

Cancer Research Area(s)
  • Brain Cancer
  • Drug Discovery and Development
  • Skin Cancer

Research Focus

Conformation-biological activity relationships in peptides/proteins including GnRH, gastrin, antibacterial peptides, amyloidogenic peptides and chlorotoxins. Structural characterization of prestin. Inhibtion of biological activity of 14-3-3e protein.  Description of solution structure of polypeptides by Molecular Dynamics simulations and ab initio quantum chemical calculations. Effects of weakly polar interactions on peptide/protein structures using the above theoretical methods and vibrational  and/or electronic circular dichroism spectroscopy.
