AIPL Research Geneticists

George Wiggans Wiggans, George
george.wiggans@ars.usda.gov
(301) 504-8407

Investigates methods to improve accuracy of genetic evaluations of yield traits, type traits, and calving ease, including use of genomic data. Conducts genetic evaluation of dairy goats. Advises on procedures to develop, improve, and access the national database and on distribution of evaluation information.


Paul VanRaden VanRaden, Paul
paul.vanraden@ars.usda.gov
(301) 504-9438

Investigates genetic differences among dairy cattle for yield, longevity, fertility, and udder health traits. Determines economic values for traits included in Net Merit. Examines effects of inbreeding, crossbreeding, and non-additive genetic merit. Develops statistical methods to improve national and international genetic evaluations and to use genomic data in predictions.


John Cole Cole, John
john.cole@ars.usda.gov
(301) 504-8665

Investigates genetic differences among dairy cattle for calving ease, stillbirth, persistency of yield, and health traits. Develops tools for analyzing genomic data. Studies relationships between genetic markers with large effects and economically important phenotypes. Evaluates changes in genetic diversity in U.S. dairy cattle over time.


Derek Bickhart Bickhart, Derek
derek.bickhart@ars.usda.gov
(301) 504-8592

Investigates methods to utilize sequence data to improve the accuracy of genetic evaluations. Develops tools for analyzing sequence and array-based genomic data. Studies the impact of trans-generational epigenetic effects on genetic prediction. Conducts research using genetic annotations and functional predictions to refine disease loci and discover causative variants.
