More than 40 student-led research projects took center stage this week as Texas Tech’s Department of Natural Resources Management hosted its fifth annual Research Day, an event that has become a defining feature of the department’s academic year.

'NRM’s annual Research Day provides a valuable venue for our students to debut their finest and most innovative research, receive feedback, interact collegially and foster a culture of research excellence.'

Held Tuesday, April 21, at the Texas Tech Dairy Barn, the symposium brought together undergraduate and graduate students at varying stages of their academic careers, offering a professional-style forum where original research was presented, examined and discussed.

The symposium is as much workshop as it is showcase. Students are expected not only to present their findings, but to defend them -  answering questions from faculty members, peers and visiting experts whose critiques often shape the next phase of research.

“NRM’s annual Research Day provides a valuable venue for our students to debut their finest and most innovative research, receive feedback, interact collegially and foster a culture of research excellence and professional scholarship,” said Richard Stevens, chair of the department and the Caesar Kleberg Endowed Professor of Wildlife Conservation.

For many participants, the experience serves as an early test of their readiness for larger stages, where expectations are higher and scrutiny more exacting. It is, in effect, a rehearsal for the broader academic world.

The scale of this year’s event reflected its steady growth. According to Carlos Portillo-Quintero, the symposium’s coordinator, 41 abstracts were submitted by students, with 16 judges evaluating the presentations.

“First of all, we again thank the support received from the department to make this event happen every year,” Portillo-Quintero said. “And thanks to all of the faculty and collaborators who volunteered as judges.”
