In early February 2025, Walla Walla University department of biological sciences invited Bill Hayes, Loma Linda University professor and WWU alum, to present “The Kiss of Death: Venom Composition Variation and Why It Matters,” which focused on venomous animals that deliver toxins through a wound created by a bite, sting or puncture. Hayes' presentation was part of the biology department’s quarterly colloquium series.
Hayes spoke most specifically about rattlesnakes and their incredible chemical weaponry. Mirana Ramorasata, junior pre-med biology major, went to the colloquium because of the presentation's applications to her future career plans as a doctor. She said Hayes’ expertise was a helpful insight for understanding clinical experiments geared towards snake venom. Hayes talked about the importance of the quantity and composition of injected venom and medical applications of venoms, often being utilized in diagnostic tools, antivenoms and even cancer treatments.
Aurora Coleman, senior biology major, also attended this colloquium, and she said, “Getting exposure to the type of research Hayes works on and its real-world applications was eye-opening.” Hearing from Hayes also reminded her of the similar themes across all research, such as adaptation, biochemistry, biodiversity and others.
Every quarter, the biology department invites several scientists to share their research and expertise with students. Jim Nestler, WWU professor of biology, organized the colloquium and said the department hosts scientists who actively participate in biological research in a variety of disciplines, including molecular, marine, medical, lab-based, field-based, microbiology and more. Nestler said, “Hayes' research involves several biological disciplines, so we were excited that he was able to speak with our students. In addition, rattlesnakes are cool!”
Since many of WWU biology students are exploring their future career options, including the possibility of research, they need to be aware of the wide variety of opportunities available. The biology department is especially interested in showing students possible career paths through the guidance of former students, showing what WWU alums have gone on to do with their biology degrees.
