Don Walker

I am a native Texan, born and raised in South Oak Cliff.  I later moved to Plano and graduated from Plano East in 1988.  I married my high school sweetheart, Julie, and have two amazing sons, Drew and Riley.

I hold a bachelor's and a master's degree in science with majors in biology.  My master's thesis was on the fossil snakes of the Taunton Local Fauna (Mid-Pliocene: Blancan) of Adams County, Washington.  I have over 25 years of teaching experience, ranging from middle school to the university level.

Currently, I am the team lead for environmental systems and teach courses in environmental systems and earth & space science.

My research interests include neo- and paleoherpetology.
