My students and I are
biologists at heart. Therefore, we let our intense interest in
life histories of amphibians and reptiles guide us to appropriate
to ask of these animals rather than allowing an interest in a
question force us to examine organisms
for which we have no passion. All levels of scientific inquiry
encouraged, from descriptive to experimental and from field to
Additionally, broad experiences within the field of herpetology are
These experiences include access to a number of fine field sites in Alabama and Costa Rica (regions with unusually rich herpetofaunas), participation in curation of a notable herpetological collection within the Auburn University Museum, and opportunities to influence the local populace about amphibians and reptiles through school and community programs.
The primary goal of activities in my lab is to provide new knowledge to the scientific community in the form of research publications. While the scope of this research is limited taxonomically, all graduate-level projects are expected to explore patterns of broad interest to the fields of ecology, evolution, and/or conservation biology. In this respect, students are expected to know enough about current trends in the latter fields to understand how their herp-oriented research projects might shape theory-based research. Auburn is a member of the Organization for Tropical Studies (OTS) and, therefore, our graduate students are eligible for the field course in tropical biology offered by OTS. I try to encourage all of my students to take advantage of this exceptional educational opportunity.

INFORMATION FOR PROSPECTIVE GRADUATE STUDENTS
I am always interested in recruiting bright, motivated students and typically take on 1-2 students each year. Those working in my lab are expected to generate their own projects. I do not provide students with projects because this usually stifles their scientific curiosity and because I find that my students ask much more interesting questions than I do! Typically, there are more applicants for entry into my lab than I can accept, so the competition is stiff. Those interested in entering my lab need to apply to the Department of Biological Sciences (see departmental web page) before Feb 1. During the first week of February, I select the application(s) that I will sponsor. Those not chosen are informed of my decision so they can withdraw their applications and avoid the application fee required by the Graduate School. Once I sign my support of an applicant, the file is sent to the Graduate Admissions Committee of the Department of Biological Sciences for evaluation. This committee screens applicants and assigns teaching assistantships (TA). TA assignments are guaranteed for two years for masters students and five years for doctoral students. Generally, new TA assignments are offered starting in mid-February (for students beginning their programs the following fall semester) and high GRE scores are needed for selection. Most students score 1100 or better for verbal + quantitative and have a GPA of 3.4 or better. If you are selected for a TA assignment, then this completes the admissions process for getting into my lab. Most students teach for a year, while taking courses and establishing their research program. Then we work towards finding support for the research project. This may be in the form of a graduate research assistantship on one of my funded research projects or a grant that the student garners.

ORGANIZATION FOR TROPICAL STUDIES (OTS)
What is OTS?
for Tropical Studies is a non-profit consortium of 64 research institutions
and universities from around the world. It was created in 1963 to focus on
education, research, and management of natural resources in the tropics. Auburn
University has been an OTS member institution since 1987.
As a member, Auburn students and faculty have access to educational, research, and funding opportunities that are not available to non-member institutions. OTS is involved in teaching more than 15 different graduate and undergraduate courses, environmental education, facilitating tropical research, and operating three biological research stations in Costa Rica.
What courses are available to Auburn Students?
- Field Tropical Biology
- Introduction to Field Ethnobotany
- Research Experience in Tropical Biology
Advanced Courses: (for postdoctoral scholars, junior faculty, and advanced graduate students)
What does participation in OTS do for you?
Participation in OTS courses provides Auburn students
with a complete foundation in tropical biology. In addition students have
interactions with faculty who have considerable tropical experience, students
and researchers currently doing research in the tropics, and peers on courses
who are likely to form the next generation of tropical biologists. Once
students have completed the course, there are considerable opportunities for
continued research (including logistical and financial assistance) in the
OTS offers research fellowships that are open to all
students enrolled at Auburn as well as all OTS course alumni. Through Pilot
Awards and Research Fellowships, Auburn graduate students have access to up to
$6500 for research projects in the tropics.
OTS Undergraduate Minority Scholars Program:
Minority undergraduate students at Auburn are
eligible to apply for scholarships that can be used for the full semester abroad
as well as the summer abroad courses offered through OTS. Through this program
students receive a full scholarship.
Auburn OTS Alumni:
Auburn Faculty Participants:
Agricultural Economics and Rural Sociology
