Kasey DeAtley

Associate Professor

Personal Information

Kasey DeAtley is a sixth-generation Northern Californian, having descended from a relative of John and Annie Bidwell who homesteaded in the intermountain area in the 1880s. She knew as early as the first or second grade that she wanted to be in agriculture and that she wanted to be a teacher. DeAtley transferred to CSU, Chico from Lassen College and graduated in 2005 with a degree in animal science. After graduating, she stayed on to work with Professor Dave Daley as a research associate for a year and a half, during which time she was mentored by many faculty in the College of Agriculture who helped her discover her desire to become a college professor. She completed her master’s degree in 2009 at New Mexico State University followed by a PhD in 2012 in animal science with an emphasis in reproductive physiology and beef cattle genetics.

DeAtley co-advises the Young Cattlemen’s Association. She and her sister, Kallie Graham (Animal Science, ’07), are working alongside their family to build their cattle enterprise, Two Doc’s Land and Cattle.
