Andrew Hess

Assistant Professor

Summary

Dr Andrew Hess has experience in developing bioinformatics pipeline for big data analysis, including processing and analysing sequence data for genomic selection and to identify genetic markers that can be useful to their respective industries. Adopting new technologies is something that he is passionate about, and he has been involved in project focused on developing methods to utilize real-time long-read sequencing technologies for high-throughput use in the livestock industry and adapting digital agriculture tools (e.g., accelerometers and GPS collars) for large-scale use to develop traits for genetic improvement.

Dr Hess has performed ground-breaking research in a variety of species including sheep, goats, pigs, deer, cattle and Greenshell mussels. He places heavy emphasis on research that can be delivered directly to industry.
