Teaching

ASCI 456: Beef Cattle Merchandising
Summary: Develop skills to merchandise breeding cattle including advertising, genetic and phenotype selection, data collection, and conducting a bull sale. Students in the class are responsible for planning and conducting the annual UNL bull sale.

ASCI 865: History and Perspectives in Animal Breeding Programs
Summary: Historical perspective to the discipline of animal breeding and genetics. Introduction to the contributions of geneticists who have significantly impacted the discipline. Material includes pre-recorded interviews of scientists that have had an international impact in animal breeding and genetics. Critique key papers.

ASCI 933: Linear Models and Genetic Prediction
Summary: Evaluation of methods for developing and exploiting genetic diversity among animal populations to improve bio-economic efficiency of animal production.

Research

My research focuses on the Quantitative Genetics/Genomics in livestock.

Extension

The focus of my extension programming revolves around genetic selection tools and methods in beef cattle.
