UMD Animal Sciences MS and PhD Program Guide 2026

UMD Animal Sciences Graduate Program Overview

The University of Maryland Department of Animal and Avian Sciences (ANSC) operates one of the most comprehensive graduate programs in animal sciences on the East Coast. Located at the flagship College Park campus just outside Washington, D.C., the program leverages its proximity to major federal research institutions to deliver a graduate education that combines rigorous academic training with real-world research impact.

The graduate program is inherently interdisciplinary, drawing approximately 20 graduate faculty members from the Department of Animal and Avian Sciences, the Department of Veterinary Science, and the Virginia-Maryland Regional College of Veterinary Medicine. This collaborative structure means students benefit from expertise spanning molecular biology, nutrition science, reproductive physiology, immunology, and food safety — all within a single program framework.

Under the leadership of Graduate Program Director Dr. Zhengguo Xiao, the ANSC program maintains high academic standards while fostering a supportive mentoring environment. Every student-advisor relationship is formalized through a Statement of Mutual Expectations (SME), ensuring clear communication about research goals, timelines, and professional development from day one. If you are exploring graduate programs in the biological sciences, you may also find value in our guide to the Duke University PhD Genetics and Genomics Program, which shares a similar emphasis on interdisciplinary research.

MS Degree Requirements and Curriculum

The Master of Science in Animal Sciences requires a minimum of 30 semester hours, divided between 24 credit hours of coursework and 6 hours of thesis research (ANSC 799). Students must maintain an overall GPA of 3.0 or better throughout their enrollment, with the university registrar applying strict rounding rules — a 2.9640 GPA does not qualify as a 3.0.

Core coursework requirements include satisfactory completion of a graduate-level statistics course, typically BIOM 601, which provides the quantitative foundation for experimental design and data analysis essential in modern animal science research. Students must also complete training in Research Bioethics or the Responsible Conduct of Research (RCR) through the CITI Program, reflecting the program’s commitment to ethical scientific practice.

A unique requirement is the completion of either ANSC 624 (Recent Advances in Animal and Avian Sciences) or ANSC 625 (Developing Presentation Skills) for one credit of seminar participation. This ensures that all MS students develop scientific communication abilities alongside their technical expertise. The program also strongly encourages completion of a 400-level or above biochemistry course, recognizing the increasingly molecular nature of animal science research.

Students form a Graduate Advisory Committee by the end of their first semester, comprising at least three members with two being Regular Graduate Faculty at College Park. The committee chair must be an ANSC faculty member. A Plan of Study and thesis research proposal must be approved by the advisory committee before the end of the second semester, keeping students on track for timely completion.

The MS defense consists of a public seminar presentation of thesis findings followed by an oral examination. Defense outcomes range from a pass with recommendation to pursue a PhD, to a pass with the MS as a terminal degree, providing clear guidance on academic trajectory.

PhD Degree Structure and Candidacy Exam

The Doctor of Philosophy in Animal Sciences builds upon the MS foundation with substantially more rigorous research requirements. PhD students must complete a minimum of 12 research dissertation credits (ANSC 899) after advancing to candidacy. Upon advancement, students are automatically enrolled for 6 credits of ANSC 899 each fall and spring semester until graduation.

The PhD advisory committee is more extensive than the MS committee, requiring a minimum of five voting members. At least three must be Regular Graduate Faculty at College Park, including the chair and the Dean’s Representative. Two committee members must be ANSC faculty, and the Dean’s Representative must come from another UMD department or program, ensuring external perspective on the dissertation research.

The admission to candidacy examination is a comprehensive evaluation consisting of both written and oral components. Before the exam, students meet with their committee to establish three academic focus areas. The written portion spans a preannounced one-week period, during which students answer questions from each committee member in dedicated three-hour sessions — one member’s questions per day. The oral examination follows, covering written exam issues, ongoing dissertation research, and general knowledge in the field.

PhD students must complete the candidacy exam after no more than five semesters, typically when approximately 80% of the Plan of Study coursework is complete. After passing, students receive an advancement letter from the Graduate School and qualify for a pay grade increase from step 2 to step 3 on the assistantship scale. A minimum of two additional semesters after advancement is required to complete the 12 credits of ANSC 899.

One distinctive feature of UMD’s PhD program is the mandatory teaching requirement. All PhD students must gain teaching experience equivalent to 8-10 hours of effort per week during a single semester. Students not already on a teaching assistantship are placed on at least a half-time TA position, ensuring every doctoral graduate leaves with pedagogical skills valued by both academic and industry employers.

Research Areas and Specializations

UMD Animal Sciences organizes its research enterprise around four major clusters, each representing critical frontiers in modern animal science. These clusters are not rigid boundaries — many faculty and students work across multiple areas, reflecting the inherently interdisciplinary nature of the field.

Genetics and Cell Biology

This cluster encompasses research on nutrient-gene interactions, cell biology and genetics of nutrient homeostasis, and molecular dynamics of lipid secretion. Faculty investigate the molecular basis for pluripotency maintenance and cell lineage determination, statistical genomics and bioinformatics, and gene regulatory networks. Research on molecular mechanisms of protective memory in mucosal infections and interactions between nutrition and the immune system adds a translational dimension to this work.

Reproduction and Development

Faculty in this area investigate implantation failure and early pregnancy loss through placental development, development of self-renewing pluripotent cell lines, and reproductive physiology and cryobiology. Signaling pathways regulating neural crest induction, migration, and differentiation represent cutting-edge developmental biology research. The brain-pituitary-gonadal axis regulation of reproduction, including sex-specific characteristics, rounds out this research portfolio.

Nutrient Utilization and Metabolism

Research here addresses practical challenges in livestock production, including optimization of dietary energy, nitrogen, and phosphorus use by ruminants and poultry to reduce environmental impact. Mathematical modeling of whole-animal nutrient utilization provides powerful predictive tools for the industry. Reducing methane emissions by ruminants is particularly relevant as the agricultural sector addresses climate change concerns.

Pathobiology and Infectious Diseases

This cluster spans from fundamental immunology to applied food safety. Research includes regulation of inflammatory cytokines on memory CD8 T cell generation, development of cross-protective vaccines against swine influenza, and epigenetic studies of chicken response to Marek’s disease virus. Novel vaccines against foodborne bacterial pathogen colonization and control strategies using natural products connect animal health to public health outcomes. Students interested in graduate programs with a strong public health or biomedical sciences dimension may also want to explore the BU Graduate Medical Sciences Programs Guide.

Faculty Expertise and Mentoring

The ANSC graduate program features approximately 20 graduate faculty members, each bringing specialized expertise that collectively covers the breadth of modern animal science. Department Chair Dr. Tom Porter leads research in molecular and cellular endocrinology of animal growth and development, while Graduate Program Director Dr. Zhengguo Xiao specializes in immunology.

Notable faculty include Dr. Iqbal Hamza, whose work on cell biology and genetics of micronutrient metabolism has implications for both animal and human health. Dr. Carol L. Keefer’s research in reproductive biology and embryology, Dr. Li Ma’s work in population genetics and mechanisms of complex diseases, and Dr. Jiuzhou “John” Song’s contributions to statistical genomics and bioinformatics represent the program’s strength at the intersection of traditional animal science and modern computational biology.

Dr. Lisa Taneyhill’s developmental biology research on embryonic patterning, Dr. Mohamed Salem’s omics approaches to enhance muscle growth and aquaculture production, and Dr. Andrew Schiffmacher’s development of organoid model systems from livestock species illustrate the program’s commitment to cutting-edge methodologies. In food safety, Dr. Debabrata Biswas’s work on foodborne bacterial infections connects the department to critical public health challenges.

The mentoring framework at ANSC is formalized and structured. Every advisor-student relationship begins with a Statement of Mutual Expectations (SME) that outlines responsibilities, meeting frequency, and communication norms. Students meet regularly with their advisor, have annual advisory committee meetings, and undergo annual evaluation by the Graduate Education Committee (GEC). This multi-layered system ensures that no student falls through the cracks and that concerns are identified and addressed early.

Admission Requirements and Application Process

The UMD Animal Sciences graduate program admits students competitively from around the world. The foundational requirement is a strong background in animal or poultry science, or related biological sciences including nutrition, physiology, biology, biochemistry, cell-molecular biology, genetics, microbiology, immunology, or virology. A minimum undergraduate GPA of 3.0 on a 4.0 scale is required.

The application package consists of an online application with candidate data, a statement of purpose outlining goals and relevant experiences, transcripts from all post-secondary institutions, three letters of recommendation, certified copies of earned diplomas, and the $75 application fee. Notably, GRE General Aptitude Test results are now optional, reflecting a broader trend in graduate admissions toward holistic review.

International students must submit TOEFL scores (minimum 96 for admission without provisional status) or IELTS scores (minimum 7). For teaching assistantship consideration, preference is given to students with speaking sub-scores of 24 (iBT TOEFL), 7.5 (IELTS), or 76 (PTE), reflecting the department’s emphasis on effective classroom communication.

Applicants are strongly encouraged to identify potential faculty advisors in their statement of purpose. This proactive approach signals genuine research interest and facilitates the matching process. The Graduate Education Committee reviews applications on a rolling basis after fall and spring deadlines, and the director makes decisions in consultation with the department chair. For students also considering engineering-oriented graduate studies, our Penn State Industrial Engineering Program Guide provides a useful point of comparison.

Financial Support and Assistantships

UMD Animal Sciences offers a well-structured financial support system that pools teaching and research assistantships into uniform 9.5-month graduate assistantships. This approach eliminates the uncertainty that plagues many graduate programs where students must cobble together funding from different sources each semester.

MS students can expect funding support for up to 2.5 years, while PhD students receive support for up to 4.5 years. An additional year at 50% stipend may be available for students requiring extra time to complete their dissertations. All funded students receive tuition remission for up to 10 credits per academic semester and 4 credits over winter term, substantially reducing the financial burden of graduate education.

Beyond the base assistantship, students participate in the university’s employee health benefits program — a significant advantage over programs that leave graduate students to navigate insurance markets independently. The Graduate School also offers fellowships for exceptional candidates, and students are actively encouraged to pursue external funding through Cosmos scholarships, ARPAS-ANSC Travel Awards, Graduate School Scholarships, and state and federal awards.

PhD students receive a pay grade increase upon advancing to candidacy, moving from step 2 to step 3 on the assistantship scale. This built-in progression acknowledges the increasing expertise and contributions of advanced doctoral students and provides tangible financial incentive for timely progression through the program milestones.

Research Facilities and Resources

The UMD Animal Sciences program benefits from an exceptional array of research facilities that span both the College Park campus and several off-campus locations throughout Maryland. On campus, students have access to approximately 28,000 square feet of research laboratory space, averaging about 1,000 square feet per faculty member. Supporting infrastructure includes a 2,800 sq ft cold room, a 2,000 sq ft freezer room, a 15,000 sq ft animal holding facility in the Animal Wing, and a dedicated aquaculture facility.

The off-campus facilities are where UMD’s animal sciences program truly distinguishes itself from competitors. The UM/USDA Beltsville Animal Biotechnology Facility provides 11,000 square feet dedicated to cloning, transgenic biology, and stem cell research — connecting students directly to one of the world’s premier agricultural research complexes.

The Central Maryland Research and Education Center in Clarksville spans 925 acres and supports dairy and horse research with over 200 head of Holstein cattle and 20 horses. The Applied Poultry Research Laboratory in Upper Marlboro covers 202 acres for poultry nutrition, physiology, and behavior studies. The Wye Beef Cattle Research Center on Maryland’s Eastern Shore encompasses 450 acres with 250 registered Angus cattle for beef cow-calf management, pasture management, and growth physiology research.

The department’s strategic partnership with nearby federal institutions — including the USDA Beltsville Agricultural Research Center, Patuxent Wildlife Center, and the Smithsonian’s National Zoological Park — gives students access to resources and expertise available at very few universities worldwide. Scientists from these institutions can serve on advisory committees with Special Graduate Faculty status, further enriching the mentoring ecosystem.

Career Outcomes and Professional Development

The UMD Animal Sciences program prepares graduates for diverse career paths through a comprehensive professional development framework. The mandatory teaching requirement for all PhD students ensures that graduates leave with pedagogical skills valued by universities and colleges seeking faculty with demonstrated teaching competence.

Scientific communication skills are developed through required presentations at the Annual Symposium, encouraged participation in scientific conferences (supported by travel awards), and the seminar courses ANSC 624 and ANSC 625. Students learn to communicate complex research findings to both specialist and general audiences — a skill increasingly critical in careers spanning academia, industry, government, and science policy.

The program provides Individual Development Plan (IDP) resources through the Graduate School, helping students map their career trajectories and identify skill gaps early. Mentoring conversations explicitly address different career paths and expectations, acknowledging that not every PhD graduate will pursue a tenure-track position. The proximity to Washington, D.C. opens doors to careers at federal agencies like the USDA, FDA, NIH, and EPA, as well as science policy organizations and advocacy groups.

Regular exposure to outside speakers and leading scientists provides valuable networking opportunities. The department’s connections to USDA Beltsville, the National Zoo, and other partner institutions further expand the professional network available to graduates.
