Thanks for visiting the website of the School of Biological Sciences (SBS).

Our faculty and students are engaged in exciting research, insightful education, and important public outreach that cover widely the range of biology.

  • For undergraduate students, SBS is the home to majors in biology and zoology, and each of those majors includes various options. Those options provide opportunities for students interested in health sciences, including pre-medical, pre-dental, pre-veterinary, and pre-physical therapy tracks.
  • For graduate students, SBS offers M.S. and Ph.D. degrees in botany and zoology. We have excellent educational and research facilities.
  • Using the links on this homepage you can discover more about experiences in SBS and the education and research opportunities we offer. We hope you will explore our website and please feel welcome to visit us on campus.

Professor Elissa Schwartz will be presenting a talk entitled "Identifying the conditions under which antibodies protect against infection by equine infectious anemia virus" at the upcoming HIV Symposium in Palm Springs, CA in March 2015. Gonzaga University invited her to give a talk this month entitled, "Insights into an H1N1 influenza outbreak from mathematical and agent-based modeling." Last October, she was invited to present a seminar at Pomona College. The title of the talk was "Modeling equine infectious anemia virus infection: Virus dynamics, immune control and escape.”

Professor Omar Cornejo was recently published in Genome Biology and Evolution for his work on evolutionary genomics and genetics.
Genome-wide patterns of genetic polymorphism and signatures of selection in Plasmodium vivax. Cornejo, O.E., Fisher, D. and Escalante, A.A. 2014. accepted Genome Biology and Evolution 7(1): 106-119.

Professor Hubert Schwabl’slab recently published two papers, with one other accepted, from the hormone and behavior research in free-living red-backed fairy wrens in Australia. Authors Douglas Barron and Willow Lindsay are former SBS PhD students who are now postdoctoral fellows in labs in the US, respectively Sweden.

SBS PhD candidate, Steven Micheletti, was awarded the NSF Doctoral Dissertation Improvement Grant ($19600) this month. He recently had an article published in Molecular Ecology, titled “A test of the central-marginal hypothesis using population genetics and ecological niche modelling in an endemic salamander (Ambystoma barbouri)”.

Former SBS PhD student, Gyeong Mee Yoon (2006 grad), has just been awarded and started a faculty position as Assistant Professor of Botany and Plant Pathology at the University of Purdue.

Dr. Jeremiah Busch was recently awarded a 3 year NSF grant to study the effects of range expansion on the reproductive mode in a flowering plant (Campanulastrum americanum). This research, in collaboration with Dr. Laura Galloway at the University of Virginia, will combine analyses of DNA sequence variation with greenhouse and field studies to test hypotheses regarding the evolution of self-pollination at range limits. Such a combined approach is useful in understanding why the evolution of close inbreeding is often observed near species range limits.

SBS Faculty Shelley McGuire traveled to Aarhus, Denmark in October to deliver an invited presentation entitled "Human milk: Mother Nature’s prototypical probiotic food?" at the International Milk Genomics Conference. She also gave invited presentations at the International Society for Research in Human Milk and Lactation meetings held in Kiawah, South Carolina (October, 2014) entitled "Introduction to the human milk microbiome – yes, there are bacteria in breastmilk!" and at the Glycobiology Society meetings in Honolulu, Hawaii (November, 2014) entitled "The human milk microbiome – a paradigm shift."
