Principal Investigators
Lab Director
Mrs. Martinez is the director of the Comparative Psychology Lab and a dedicated researcher specializing in primate behavior, particularly that of western lowland gorillas in zoo settings. With a strong background in psychology, she focuses on animal behavior and behavior analysis.
She actively leads research projects that explore how animals behave in captive environments, aiming to promote a better understanding of their needs and well-being. Through her work, she also seeks to raise awareness about wildlife conservation in the Rio Grande Valley.
In addition to her research, Mrs. Martinez is also a lecturer in the Department of Psychological Science at the University of Texas Rio Grande Valley and a PhD candidate in Animal and Veterinary Science at the University of Adelaide.
Curator of Behavior Research
Dr. James-Aldridge, curator of behavior research at the Gladys Porter Zoo, is a retired professor and the founder of the partnership between the zoo and the University of Texas Rio Grande Valley. With over 40 years of experience studying western lowland gorillas, she brings a deep understanding of their behavior and social dynamics.
Beyond her research, Dr. Aldridge is actively involved in training new volunteers, teaching them how to identify individual gorillas and interpret their behavior. Her mentorship continues to shape the next generation of researchers and strengthens the bridge between academic study and applied conservation work.

Zoo Partnership
Our Goal
The enduring partnership between the Psychological Department and the Gladys Porter Zoo represents a longstanding commitment to collaborative research and education. Since its initiation in the 1980s under the guidance of Dr. James-Aldridge, our students have had the invaluable opportunity to collect data on gorillas and other animals at the Gladys Porter Zoo. This collaboration not only enhances student engagement in zoo research but also serves as a platform to educate the community on conservation and the vital role of zoos. We are enthusiastic about our continued collaboration and look forward to future endeavors in advancing knowledge and awareness.
