Our Faculty and Student Support Services

Faculty members are teacher-scholars with years of academic experience and creative passions of their own. They stay active in their fields and bring their expertise to the classroom.

“Being a professor allows me to integrate two things that I love - teaching and research. In this setting, I have the opportunity to work closely with students and mentor them as they put what they’ve learned in class to use. Seeing students get inspired by the science, and in turn inspiring me to be a better teacher and scientist is a very rewarding process!  
Lisa M. Goering, PhD

“Over the years, I’ve learned that giving students direct, quick feedback and close one-on-one support works best for heading off frustration and keeping students engaged. I don’t tell them what to do or how. I remind them that this is real science, so often times, I don’t know what’s going to happen either.” 
Bill Quinn, PhD

Student Support Services

Along with personal attention and mentorship from their professors, our students have access to offices and programs outside of the classroom that support their success. We encourage students to take advantage of these resources that help them thrive and excel:

  • Academic counseling and advising
  • Supplemental instruction and tutoring
  • Career preparation and advising 
  • Writing Center consultation
  • Health and wellness counseling
  • Student disability support

Outside the Classroom

Students immerse themselves in Austin’s intellectually curious culture and benefit from the many global leaders in innovation and technology headquartered in Austin. Our programs facilitate engagement with this rich environment by providing students with opportunities for hands-on experience throughout their education.


Kamryn Gerner-Mauro ’17, Vivian Le ’16 and Associate Professor of Biological Sciences Lisa Goering raised three groups of fruit flies on diets with varying levels of protein, and then compared several indicators of reproductive capacity among females in the groups. Preliminary data suggest that malnourished female fruit flies lay fewer eggs and provide less nutrition for offspring than control groups. The research could one day give insights about nutrition during pregnancy. 

Dr. Fidelma O’Leary, Associate Professor of Biology, was awarded $275,000 by the US Department of Agriculture’s National Institute of Food and Agriculture (NIFA) to support agricultural science education at Hispanic-Serving Institutions. The 4-year grant aims to establish the “Agricultural-STEM Pipeline” project across high school and 2- and 4-year college levels in order to recruit and retain underrepresented students and facilitate their progression to graduate training or careers with the USDA in the NIFA priority area of AFRI Agricultural and Natural Resources Science for Climate Variability and Change.

St. Edward’s University has been awarded a five-year grant of more than $1.6 million from the National Science Foundation through the Improving Undergraduate STEM Education (IUSE) Program to support freshmen students studying Science, Technology, Engineering and Mathematics (STEM) courses at St. Edward's University. The The Living Learning Community/Active Learning  (LLCAL) project is under the direction of St. Edward’s University faculty members Richard Kopec, Jason Callahan, Teresa Bilinski, Tricia Shepherd and Fidelma A. O’ Leary.


At the annual meeting of the Texas Academy of Sciences in San Antonio, Texas, 11 Biology students won awards for outstanding research presentations. In addition, 32 St. Edward’s University students were co-authors on a paper published in the scientific journal Genes Genomes Genetics. This research was completed as a part of the Research Explorations in Genomics course taught by Bioinformatics Professor Charles Hauser.

Evolutionary Foundation for Curricula

At St. Edward’s University, all curricula in the Biological Sciences are founded upon evolutionary theory. As a subject of scientific inquiry, the theory of evolution provides opportunities for testing of hypotheses that strengthen our understanding of the processes that account for the diversity of life on earth, and existing data overwhelmingly support the theory as scientifically sound. We regard any non-scientific or teleological attempts that distract from the scientific processes that underlie science as, at best, a diversion to our mission to provide exceptional education to our students in the Biological Sciences. We stand with the numerous scientific societies that have issued statements on the subject of evolution and intelligent design, confirming the demonstrated success of the former and rejecting the scientific viability of latter.
