I have spent my entire life wandering around in the woods. I spent my formative years as an indentured field assistant to my dad who is an ichthyologist. Went to Berry College in Rome GA for my undergraduate degree and nearly became a botanist, but ultimately my love for turtles and snakes won out. I spent several years doing biological consulting work then became a field assistant at the Jones Ecological Research station in SW Georgia. I ended up doing my master's work there through Auburn University on seed dispersal by gopher tortoises. I made an attempt at a PhD but that ended up not being in the cards. I am currently an education/outreach specialist for a state science program for public high schools and am based at Auburn University. The fauna and flora of the southeastern US are my main interest areas but I enjoy all natural history. Box turtles and gopher tortoises are the taxa I am most interested in.
