“Nothing in biology makes sense except in the light of evolution.”

- Theodosius Dobzhansky, evolutionary biologist

Chris A. Hamilton


My goal as an advisor is to help students become broadly trained in arthropod systematics and phylogenetics while they develop as independent researchers by learning to identify interesting questions and the approaches necessary to address those questions. As a Native person in academia, I want to be effective in my roles – as a mentor, as a holder of knowledge, and as an educator.

Graduate Students

PhD students

Karina Silvestre Bringas


Karina is working on understanding the diversity and evolutionary history of the tarantula genus Aphonopelma across the Madrean Pine-Oak Woodlands Hotspot (aka - the sky islands of southern Arizona, New Mexico, and northern Mexico). This is Karina holding a mature male A. catalina.

Karina comes to us from Marshal Hedin’s lab at San Diego State University, where she worked on jumping spider research as an undergraduate.

Erik Ciaccio


Erik is working on understanding the species diversity and evolutionary patterns and processes within the trapdoor spider genus Antrodiaetus. This is Erik finding his very first Antrodiaetus, in the Galiuro Mountains of Arizona!

Erik also comes to us from Marshal Hedin’s lab @ SDSU, where he got his Masters working on the spider genus Hypochilus. Thank you Marshal!
