Biography and Research Information
OverviewAI-generated summary
Collis R. Geren's research has focused on the isolation and characterization of various toxins and enzymes from animal venoms and digestive fluids. His work includes the study of hemorrhagic proteinases from timber rattlesnake and northern copperhead venoms, as well as toxins from the brown recluse spider, *Loxosceles reclusa*. Geren has investigated the substrate specificity and enzymatic properties of these compounds, including their hemolytic activity and synergistic effects with other venom components like adenosine triphosphate. He has also examined the proteolytic activity in the digestive fluid of insect larvae, *Trichoplusia ni*. Geren's published work spans several decades, and his scholarship metrics include an h-index of 18, with 46 total publications and 920 total citations.
