In a world facing rising demand for sustainable protein, climate pressures on agriculture, and the need for more efficient livestock systems, genomics has emerged as one of the most powerful tools available. The U.S. Department of Agriculture’s Agricultural Research Service (ARS) is now offering a prestigious postdoctoral research opportunity that places early-career scientists at the center of this transformation.
The USDA-ARS Postdoctoral Research Fellowship in Computational Biology invites qualified researchers to develop next-generation bioinformatics and genomics tools for ruminant species, with a primary focus on cattle. Hosted at the renowned Animal Genomics and Improvement Laboratory (AGIL) within the Beltsville Agricultural Research Center in Maryland, this fellowship offers the chance to work on high-impact projects that directly support genetic improvement programs used by producers across the United States and beyond.
If you are completing or have recently earned a doctoral degree in bioinformatics, computational biology, genetics, animal science, statistics, or a related field—and you are a U.S. citizen—this opportunity could accelerate your career while contributing to solutions for global food security and sustainable agriculture.

Why Ruminant Genomics Matters Now More Than Ever
Genomic selection has already revolutionized dairy cattle breeding. Since its widespread adoption in the United States around 2009, it has dramatically reduced generation intervals and more than doubled the rate of genetic progress for key traits such as milk yield, fertility, and health. Today, millions of cattle genotypes are housed in national databases, and genomic tools are routine on progressive farms.
However, current methods still face limitations. Most analyses rely on a single reference genome that cannot fully capture the genetic diversity present across breeds, populations, and crossbred animals. Structural variants, breed-specific alleles, and complex repetitive regions often remain undetected or poorly characterized. Epigenetic modifications, such as DNA methylation patterns that influence gene expression without altering the underlying DNA sequence, add another critical layer of information that is only beginning to be integrated into breeding decisions.

Pangenomes—comprehensive representations of genetic variation across multiple individuals or breeds—offer a promising solution. When combined with long-read sequencing technologies that produce highly contiguous genome assemblies, researchers can build richer resources that improve variant discovery, imputation accuracy, association studies, and ultimately genomic predictions.
This fellowship is designed to help close these gaps by creating automated, scalable pipelines and improved statistical frameworks that livestock geneticists and breeders can use to accelerate progress toward more productive, resilient, and sustainable cattle populations.
The Research You Will Conduct
Under the mentorship of Dr. Benjamin Rosen, you will contribute to projects focused on characterizing the structure and function of ruminant genomes and applying those insights to discover genetic variation affecting economically important traits.
Core activities include:
- Designing and customizing bioinformatics pipelines that automate the processing of large-scale short-read and long-read sequencing datasets for the discovery of SNPs, CNVs, and epigenetic (DNA methylation) variation.
- Generating high-quality genome assemblies from long-read sequencing data and constructing pangenomes that better represent genetic diversity in cattle and other ruminants.
- Developing and refining statistical methods that incorporate new reference genomes and pangenomes into genome-wide association studies (GWAS) and quantitative trait loci (QTL) mapping.
- Enhancing genomic prediction models used in livestock selection programs, with the goal of improving accuracy for traits that are difficult or expensive to measure directly.
The work is highly applied. Results are intended to support real-world breeding programs that help farmers select animals earlier and more accurately, reduce generation intervals further, improve animal health and welfare, and lower the environmental footprint of beef and dairy production through better feed efficiency and disease resistance.
Skills You Will Master and Career Advantages
This fellowship is structured as a rich training experience. By the conclusion of your appointment, you will be able to:
- Explain the organization of the bovine genome and how modern genomic tools reveal both genetic and epigenetic variation.
- Differentiate and interpret SNPs, CNVs, methylation patterns, and functional elements such as enhancers and promoters in cattle.
- Build and customize automated pipelines for short- and long-read sequencing analysis.
- Apply computational approaches to detect genetic and epigenetic variation in livestock datasets.
- Produce genome assemblies and pangenome resources from long-read data.
- Design, implement, and interpret QTL mapping and association studies in the context of economically important traits.
- Evaluate and improve genomic prediction models for use in selection programs.
- Translate genomic findings into practical recommendations for accelerated genetic improvement in cattle.
These competencies are in strong demand. Graduates of similar ARS and computational genomics programs have moved into roles at leading universities, national laboratories, global breeding companies, agricultural biotechnology firms, and international research organizations. The combination of federal research experience, high-visibility publications, and direct relevance to industry needs creates a powerful platform for long-term career success.
