Learn from Researchers Advancing the Field

Doctoral students work alongside internationally recognized faculty whose research spans botany and phycology, microbiology, molecular, cellular, organismal and population biology, fisheries biology, aquaculture and mariculture, microbial interactions and microbiomes, anatomy, physiology, behavior, genetics, evolution, and marine and wetland ecology. Faculty lead active research programs supported by competitive grants and partnerships, creating opportunities for students to contribute to meaningful discoveries while building their own research portfolios.

Study in One of North America's Most Distinctive Coastal Environments

Situated on its own island campus along the Texas coast, Texas A&M University-Corpus Christi provides direct access to globally unique marine ecosystems, including bays, estuaries, barrier islands, wetlands, seagrass meadows, tidal flats, offshore waters, and the Laguna Madre, one of the world's few hypersaline lagoon systems. Students gain hands-on experience studying marine organisms and biological processes across diverse habitats that support globally important fisheries, migratory bird populations, and coastal wildlife.

Conduct Research That Makes an Impact

Research is at the center of the doctoral experience. Students work closely with faculty mentors and graduate advisory committees to develop research questions, design studies, analyze data, publish findings, and communicate results to scientific audiences. Doctoral students are expected to contribute original knowledge to the field through dissertation research and scholarly publication.

Access Advanced Facilities and Technology

Students have access to specialized laboratories, biological analytical facilities, marine population and ecosystem observation technologies, molecular research equipment, high-performance computing resources, and research vessels. These resources support investigations ranging from molecular biology, genetics, anatomy, physiology, and behavior to organismal biology, fisheries biology, aquaculture, microbiology, evolution, and marine and wetland ecology.

Funding and Professional Development Opportunities

Qualified students may be eligible for teaching assistantships, graduate research assistantships, fellowships, travel support, and faculty-funded research opportunities. These experiences help students present at professional conferences, publish scholarly work, expand their professional networks, and prepare for successful careers in academia, government, education, conservation, and industry.
