Resources for Graduate Study
The Department of Biology offers graduate programs designed to prepare students for careers in academic institutions, government agencies and industry. The Biological Sciences Complex is centrally located on the campus of Texas A&M University. Graduate research is emphasized in over 50 laboratories that contain modern and sophisticated instrumentation for cellular, molecular, organismal and ecological studies. These laboratories provide opportunities for a broad spectrum of research specializations. The Microscopy Imaging Center, animal care facilities and a state-of-the-art DNA sequencing laboratory are among the many facilities housed in the Biological Sciences Complex.
The Department of Biology faculty has research interests that interface with those of faculty in the Colleges of Agriculture and Life Sciences, Geosciences, Medicine and Veterinary Medicine. Biology faculty participate in interdisciplinary programs in biological clocks, filamentous fungi, genetics, genomics, neuroscience and plant sciences. Cooperation is encouraged to broaden the research experience of graduate students.
Areas of Specialization in Graduate Research
PhD and MS degrees are offered in Biology, Botany, Microbiology and Zoology. General areas of research interests within these degrees include:
Cellular and Developmental Biology. Plant protoplast and tissue culture, transformation and regeneration; molecular biology and genetics of development and differentiation; nuclear organization; developmental neurobiology; cell surface interactions; physiology of photosynthesis.
Evolutionary Biology. Modern and classical approaches to plant and animal systematics and evolution; genomic and biochemical evolution; cytogenetics.
Molecular Biology. DNA and RNA isolation, cloning and sequencing; gene isolation, characterization, transfer and expression; bacterial and phage genetics; molecular processes of differentiation and embryogenesis; molecular microbiology and virology; genomics and informatics.
Organismal Biology. Comparative endocrinology and physiology; neurobiology; invertebrate ecology and ethology; marine biology; biological clocks.
Entrance Requirements
Course work taken at the baccalaureate level normally must include mathematics through calculus, statistics, chemistry including organic chemistry, biochemistry, physics, genetics and adequate preparation in a biological science. Any remedial work will be in addition to the semester hours required for the degree. Graduate admissions decisions are based on students’ academic record, research experience, letters of recommendation, GRE scores (verbal, quantitative and analytical) and suitability of students’ research interests for programs in the department. For information about admissions, contact the Graduate Advisor, Department of Biology or visit us on the website at www.bio.tamu.edu.
Language Requirement
The Department of Biology has no foreign language requirement for any graduate degree program.
Biology
The PhD degree program in Biology is designed to provide the student with training in cellular, molecular and developmental biology, and to prepare the student for a leadership position in academic or industrial research. The Department of Biology offers a broad spectrum of research opportunities including plant molecular biology, molecular and cell biology of differentiation and development, gene structure and regulation in eukaryotic and prokaryotic organisms and their viruses, and cell structure and function. Students obtaining a degree in biology may also work closely with faculty in biochemistry, entomology, genetics, plant physiology, medicine and veterinary medicine.
Biology PhD students must demonstrate competence in their specific area of research and are expected to develop proficiency in four of the following seven areas at the time of the preliminary examination: biochemistry, cell biology, developmental biology, genetics, microbiology, computational/mathematical biology and molecular biology. An MS student must demonstrate competence in at least three of the above seven areas at the time of the final examination.
