Research

Current research interests include the application of chromatography and mass spectrometry tools to the structural analysis of novel biomolecules in arachnid and reptile venoms and amphibian defensive skin secretions. The development of analytical techniques for metabolomic studies relevant to human disease is also if interest.

I am also interested in active learning approaches to engage bioscience students especially in larger lecture scenarios.
