Quantitative Genetics Intern

The Quantitative Genetics Intern supports the development of new genetic evaluations for economically and biologically relevant traits in internal beef and dairy breeding programs. Working with the Product Development and Innovation quantitative genetics team, the intern will apply contemporary single-step genomic evaluation methods and the BLUPF90 family of programs to phenotypic, pedigree, and genomic data. The internship is designed to produce a defined technical deliverable while providing practical experience with the development, validation, documentation, and application of genetic evaluations in commercial livestock breeding programs.
Based in Madison, Wisconsin, the intern will work with R&D scientists and laboratory staff on basic and/or applied research related to reproductive biology, cell biology, embryology, or vitro fertilization.

RESPONSIBILITIES

Genetic Evaluation Development and Implementation

• Contribute to the development of one or more genetic evaluations for traits relevant to internal beef and dairy breeding programs.
• Define analysis populations, contemporary groups, fixed and random effects, and other model specifications in collaboration with team geneticists.
• Estimate or evaluate genetic parameters and implement single-step genomic evaluations using appropriate programs within the BLUPF90 family.
• Compare alternative data edits, model specifications, or evaluation scenarios and summarize implications for prediction quality and operational use.

Data Management and Quality Assurance

• Prepare, integrate, and quality-control phenotypic, pedigree, and genomic datasets used in assigned evaluations.
• Assess evaluation outputs for convergence, data integrity, predictive performance, bias, stability, biological plausibility, and suitability for use in breeding decisions.

Analytical Programming and Workflow Development

• Develop reproducible scripts and workflows for data preparation, program execution, results processing, validation, and reporting.
• Document datasets, code, parameter files, methods, assumptions, quality-control rules, analytical decisions, limitations, and results to support reproducibility and future implementation.

Technical Communication and Project Collaboration

• Participate in regular project meetings, communicate progress and technical risks, and incorporate feedback from quantitative genetics and business stakeholders.
• Prepare and deliver a final technical report and presentation summarizing methods, results, limitations, and recommended next steps.
