I teach courses in Cell Biology, Molecular Biology, Immunology, and Microbiology and conduct research in these areas as well.  My research interests focus on the molecular mechanisms of cell signaling (signal transduction) and gene expression in immune responses to bacterial infection and in oncogenic signaling and chemotherapy responses in cancer. I also use the tools of molecular evolutionary biology and phylogenomics to study the evolution of cell signaling in the transition from unicellular to multicellular life and the molecular origins of animal complexity.

I have worked with Beloit students on biomedical laboratory research projects such as:

  • Molecular responses of B lymphoma cancer cells to chemotherapy drugs
  • Immune cell signaling pathways triggered by bacterial molecules and B cell/T cell interactions
  • Cellular responses to DNA damage and oxidative cell damage by free radicals and reactive oxygen species (ROS)
  • Interactions between microbes and the host immune response and cloning of bacterial pathogenesis genes
  • Non-neuronal effects of neurotransmitters in the immune system and the evolutionary origins of synaptic signaling
