Our faculty perform cutting-edge research in a wide array of biological sciences in the laboratory and in the field. Our graduate research programs prepare scientists for careers in academia, industry and government and enhance our understanding of the central role of biological systems in the global environment. Our undergraduate students gain a firm foundation in modern biological sciences to prepare them for a multitude of careers that depend on a solid understanding of biology.


Graduate Education in Biology

Our Graduate Program in Biology offers a diverse range of integrative training opportunities for students seeking a Ph.D. degree in the biological sciences. We offer training in multiple disciplines within Biology, including Molecular, Cellular and Developmental Biology, Ecology and Evolutionary Biology, Genetics, Genomics and Bioinformatics, Neurobiology and Behavior, Microbiology, Plant Biology, Biological Clocks, and Physiology and Systems Biology.

All students in our program receive rigorous academic training in biology and carry out their research in competitive, state-of-the-art research labs. Many faculty research programs span multiple research areas and levels of biological organization, creating a dynamic training environment for graduate students. Evolutionary theory sets the stage for many cross-disciplinary research collaborations among our diverse faculty. Our graduate students conduct creative, independent research and scholarship. Graduates of our programs prepare themselves for a wide range of career opportunities and gain positions in academic institutions, government agencies, and industry.

Postdoc Position in Merlin Laboratory

The Merlin lab at Texas A&M University (https://www.merlinlab.org) has a position open immediately for a post-doctoral fellow to develop CRISPR/Cas9-mediated knock-in approaches in monarch butterflies to tag clock neurons in vivo and study the clock circuitry that controls seasonal behavior. Our mechanistic understanding of how circadian clocks drive the seasonal output at the molecular and cellular levels has been limited by the lack of robust seasonal behaviors in genetically tractable model systems, and the lack of powerful genomic and genetic tools in non-model species that display robust seasonal behaviors. The migratory monarch butterfly has emerged as a promising model to study the molecular and neuronal mechanisms by which circadian clocks control seasonal behaviors because it exhibits a compelling repertoire of clock-controlled seasonal traits, its clockwork is well characterized, and its genome is sequenced and amenable to CRISPR/Cas9-mediated genetic manipulation.

These studies will employ advanced molecular, genetic and cell imaging tools. Successful applicants should have a PhD in a related field, a demonstrated track record of productivity, and experience in molecular neurogenetics. Experience in tissue imaging is a plus, but is not a requirement. Qualified candidates will be expected to work both independently and as part of an interactive team. We offer a supportive working environment in a lively international research team.

Applicants should send (1) their CV, (2) a cover letter with a statement of research interests and career goals, and (3) the name, email and phone numbers of three references to Christine Merlin via email: cmerlin@bio.tamu.edu

PhD/Postdoc Position in Schartl Laboratory

In the framework of a German/French collaborative project we are seeking for highly motivated PhD students or postdocs to study the role of transposable elements in normal and pathological development. We use small aquarium fish models for our research and selected pigment cell development and melanomatous cancer as well as gonad development and sex reversal as our target. Transposable elements (TEs) are a major constituent of all eukaryotic genomes. In humans, they make up at least 45% of the DNA in our cells. Because they are repeated, mobile and carry regulatory sequences, TEs have the potential to rewire regulatory networks and promote their fast evolution. TEs are able to insert into new locations and to recombine in genomes, leading to rearrangements and sometimes to mutant phenotypes, including genetic diseases in humans. In addition, they play a major role in the evolution of host gene functions through their recruitment as new exons or even new genes, a phenomenon called “molecular domestication”. TEs can also contribute regulatory RNAs and new regulatory sequences to host genes, thereby modifying their expression. Our study will use on the one hand bioinformatic analyses of next generation data and on the other hand functional experiments including cell culture studies and the generation of transgenic and CRISPR/Cas9 knock-out fish.

Successful applicants should have an excellent degree in Biology, Molecular Medicine or Biochemistry and broad experience in common laboratory techniques and/or bioinformatics. Fluent English or German is essential. We offer a well-equipped working environment in a lively international research team (http://www.pch1.biozentrum.uni-wuerzburg.de/).

Post-doctoral Position in Hardin Laboratory: Circadian timekeeping and output mechanisms

The Hardin lab (http://www.bio.tamu.edu/index.php/faculty/hardin/lab/) seeks a post-doctoral fellow to study novel transcriptional, post-transcriptional and post-translational regulatory mechanisms required to keep circadian time and/or drive locomotor activity rhythms using Drosophila as a model system. These studies will employ advanced biochemical, cell imaging, genomics and computational tools to define the roles two key clock genes, clockwork orange (cwo) and vrille (vri), play in regulating rhythmic gene expression. Candidates with the desire to develop projects for future independent research positions are encouraged to apply. Preference will be given to candidates with a strong track record of graduate training and experience in the molecular genetic analysis of circadian clocks, biochemical and genomic analysis of gene expression, Drosophila neurogenetics, tissue and subcellular imaging of protein localization and/or behavioral analysis. Qualified candidates will have a PhD in a related field, be expected to work both independently and as part of an interactive team, and should have excellent written and oral communication skills.

Applicants should send (1) their CV with bibliography, (2) a cover letter with a statement of research interests and career goals, and (3) contact information for three references to Dr. Paul Hardin via email: phardin@bio.tamu.edu
