Meet The Team


Principal Investigator
Dr. Obed Hernández-Gómez
I am an El Paso, TX native and proud to be serving as an assistant professor at NMSU! I worked with hellbenders for my PhD research and they still hold a special place in my heart. I have been lucky to also work with Pacific coast salamanders, turtles, and now New Mexican wildlife. My research interests are in wildlife disease ecology, population genetics, microbial ecology, and herpetology. I teach Principles of Fish and Wildlife Management (FWCE 2110), Wildlife Disease Management (FWCE 542) and Herpetology (FWCE 467) in the Department of Fish, Wildlife and Conservation Ecology.

PhD Student and Vivarium Manager
Sara-Ashley Collins
I am a PhD student in the OHG lab within the Plant and Environmental Sciences department, originally from Marietta, Georgia. After earning my B.S. from the University of Georgia, I recently completed my M.S. at Colorado State University. My research focuses on understanding how climate and environmental changes impact amphibian stress physiology and disease dynamics. With a foundation in neuroscience and natural resources, I am passionate about combining these fields to explore the complexities of herpetofauna disease. I am excited to continue building my expertise and aim to pursue a career in research and teaching as a faculty member at a research institution, where I can contribute to the field of wildlife disease and mentoring future scientists.

PhD Student and NSF GRFP Scholar
Alejandro Gomez
I am a Las Cruces native, and my current research is focused on exploring the gut microbiome and internal parasites in native and non-native ungulates in Southern New Mexico, evaluating seasonal shedding rates, diversity and load. I plan to have a career focused on enhancing the management of native and non-native species, learning the drivers for habitat selection, and investigating the impacts of anthropogenic activities on animal behavior.

PhD Student
Domonic Jimenez
I was born and raised in Las Cruces, New Mexico. I have recently graduated from NMSU with my BS in Wildlife Management and Ecology. As an undergrad, my research was focused on the nest occupancy and diet habits of the American Kestrel in the Mesilla Valley. I am now beginning a Master’s Program in the OHG Lab focusing on population genetics and immunogenetics of Western Pond Turtles on the West Coast. I will look to continue pursuing higher education and become the first in my family to receive a PhD!

Masters Student and Fulbright Scholar
Blanca Aimee Cabrera Cuellar
Born and raised in Torreón, Coahuila, México. I obtained my Bachelor’s degree in Biology from Universidad Juárez del Estado de Durango (UJED). Between 2017 and 2024, I contributed to technical and research teams on sea turtle conservation projects in nesting zones of the Pacific Ocean, the Gulf of México, and the Caribbean Sea. As a Fulbright scholar, I am currently pursuing a master’s in Fish & Wildlife Conservation Ecology. At the OHG Lab, my research centers on nesting ecology and genetic relatedness of northwestern/southwestern pond turtle (Actinemys marmorata/Actinemys pallida). After completing my degree, I will continue working with non-profit organizations on wildlife conservation initiatives.

Masters Student
Charisa "Cherry" Bell
I was born and raised in the northern communities of New Mexico. I graduated with a B.S. in Biology from the University of New Mexico, where I worked as a Genetics Technician in the Turner Lab, focusing on mitochondrial DNA for the Silvery Minnow project and several other fish species. I then took a break from school and gained experience working with the Rocky Mountain Youth Corps and the U.S. Fish and Wildlife Service as a Biological Science Technician, where I contributed to habitat restoration projects supporting biodiversity at Valle de Oro National Wildlife Refuge. Now, I look forward to pursuing my master’s degree and studying the Sacramento Mountain Salamanders.

Undergraduate Research Student
Yamilex Rodriguez
I am a junior at NMSU majoring in Animal Science. In the future, I hope to become either a Small Animal or Exotic Veterinarian. Im excited to join Dr. OHG’s lab to gain more experience & knowledge when it comes to wildlife and research!

Undergraduate Research Student
Francis Silva
I'm from southern Arizona, and am an undergraduate at NMSU majoring in Conservation Ecology, as well as Biology. I am very excited to be working on a project looking at the bacterial diversity on the skin of Chiricahua leopard frogs. In my future career, I intend to use my experience and education to work in wildlife conservation and foster positive human-animal interactions.

Undergraduate Research Student
Ashley De La Rosa
I’m a double major in Biology and Microbiology at NMSU with a focused interest in pathogenic microorganisms — particularly how they survive, adapt, and interact with the host. I currently work with Listeria and am excited to expand my knowledge in Dr. OHG’s lab to learn more about Bd disease resistance, deepening my understanding of how different pathogens affect their hosts. Born in El Paso and raised in Ciudad Juárez, I proudly serve as the captain of NMSU’s mariachi, celebrating my culture while navigating life as a first-generation college student.
Lab Opportunities
The OHG Lab has no open positions at the time.
If you are interested in volunteering, please send Dr. OHG a copy of your CV/Resume and transcripts to begin a conversation.
Lab Alumni
Jebosh Jonathan Guzman Solis
NMSU
For his MS thesis, Jebosh focused on projects dealing with turtle and amphibian disease. Jebosh worked with western pond turtles, assessing the effects of anti fungal treatment on the skin microbiome. He also studied disease resistance in Chiricahua leopard frogs along New Mexico and Arizona. He is looking for wildlife conservation opportunities through government agencies hoping to focus on fieldwork.
Jebosh graduated from NMSU Summer 2026
Robyn Montelongo
NMSU
Robyn was the Animal Care Manager in the OHG Lab Vivarium from 12/2024-12/2025. She also led projects dealing with snake fungal disease and white nose syndrome. She helped extract and sequence DNA from western pond turtles too. Robyn is in line to publish two papers from her undergrad research!
Robyn graduated from NMSU December 2025
Nathan Green
NMSU
Originally from the San Francisco Bay Area, Nathan studied turtle populations across the Pacific Northwest. His research in the lab used geospatial analysis tools to determine how environmental variation in habitat can affect disease presence, pathogen load, and movement behavior in northwestern pond turtles (Actinemys marmorata). He is actively looking for new opportunities in conservation biology that encourage interdisciplinary discovery.
Nathan graduated from NMSU May 2026
Now: Laboratory Tech at Wildcat Discovery Technologies
