Academic Positions

Assistant Professor.
August 2003 - Present. The University of Texas - Pan American, Edinburg. Areas of Specialty: Vertebrate Physiological Ecology and Herpetology
Teaching Responsibilities: BIOL1402 - General Biology II, BIOL2402 - Comparative Vertebrate Anatomy (Spring and Fall), BIOL4309/5309 - Herpetology (Spring), BIOL4311/5311 - Ecological Physiology (Fall).

Postdoctoral Associate and Assistant to the Director. August 2002 to July 2003. The University of Florida, Gainesville and Seahorse Key Marine Laboratory. Advisor: Harvey B. Lillywhite. We are investigating the ecology and physiology of the interactions between nesting birds and snakes on Seahorse Key (an insular ecosystem that is both water and food limited). In addition to the research, I provided support to the director (H.B. Lillywhite) by helping to manage the activities of the employees and visitors to the island.

Instructor. Spring semester, 2002. The University of Arkansas, Fayetteville. I was the instructor of record for Comparative Vertebrate Morphology. In addition to my lecture duties, I handled the logistical operations of the Comparative Vertebrate Morphology Laboratory and managed one teaching assistant.

Physiology Laboratory Coordinator.1996-2001. The University of Arkansas, Fayetteville. In conjunction with S.J. Beaupre, I developed the teaching curriculum for the Comparative Physiology Laboratories. I handled the logistical operations of both the Comparative Physiology and the Human Physiology Laboratories and managed up to seven other teaching assistants per semester.

Graduate Teaching Assistant. 1996-2001. The University of Arkansas, Layetteville. Comparative Physiology Laboratory (6 semesters); Human Physiology Laboratory (6 semesters).

Research Assistant. 1997-2002. The University of Arkansas, Fayetteville. Conducted laboratory research of metabolism and energetic allocations in timber rattlesnakes (Crotalus horridus) for NSF-funded projects (to S.J. Beaupre).

Graduate Teaching Assistant. 1993-1996. The University of Mississippi, Oxford. Major's (5 semesters) and Non-major's (1 semester) Introductory Biology Laboratories; Ecology Laboratory (1 semester); Biology of the Reptilia Laboratory (1 semester); Biology of the Amphibia Laboratory (1 semester).

Instructor. 1994 and 1995. NSF Young Scholars Program, The University of Mississippi, Oxford (summers); Field ecology and herpetology instructor.

Research Interests

My research focuses on understanding the environment-physiology interaction that shapes the distribution of organisms. How an organism allocates time and energy under varying environmental conditions is a central theme in my research. I am particularly interested in the mechanisms that establish geographic range limits under sub lethal conditions, geographic variation in physiological traits, brumation/hibernation ecology, and how current allocation strategies may be used to predict future responses as global climate changes. My interests also include the proximate and ultimate mechanisms that may influence semelparity and iteroparity in related species.
