Hi, my name is Joshua Castillo, and I am a senior at the Univeristy of Arizona double majoring in
Molecular and Cellular Biology and Physiology. I currently work in the Zarnescu lab where we
study neurodegenerative diseases such as ALS using fruit flies as our model organism. Outside
of the lab, I enjoy playing video games, hanging out with friends and plant shopping.
