Whitney L. Crossland, Ph.D.

Whitney Crossland grew up in the Denton, Texas, where she was active in FFA and worked for her family’s Red Angus cattle operation. Crossland attended Tarleton State University and competed on the 2005 Meat Judging Team before she transferred to Texas A&M University again competing on the 2007 Meat Judging Team. Crossland earned her B.S. (2008) and M.S. degrees in Animal Science (2011) from Texas A&M University. Between her masters and doctoral program she was a an Ag Teacher and FFA advisor at Hereford Junior High School-Preparatory Academy in Hereford, Texas, and also a sales representative with Wapanucka, Oklahoma's Diamond G Animal Health providing pharmaceutical needs to local producers of southeastern Oklahoma. Crossland then attended Texas A&M University to complete her Ph.D. in Ruminant Nutrition (2018).

After obtaining her Ph.D. she joined the faculty at Texas Tech University as an Assistant Professor of Animal Nutrition. Her teaching responsibilities include undergraduate General Animal Science, Principles of Nutrition, and graduate Ruminant Nutrition and advising over 75 undergraduate and graduate students. Crossland also offers a summer course “Comparative Beef Production Tour” for both undergraduates and graduates to gain perspective and network in the beef industry.
