James Cassidy doesn’t fit the stereotypical image of a scientist. Two star-shaped earrings dangle from his left ear. A fetching fedora is perched on top of his head. He’s swapped his white lab coat for a charcoal sports jacket. A chic checkered shirt peeks out underneath. His alert grey eyes are framed by dark glasses. When he walks into a lecture hall, students notice. Undergraduates and graduate students alike praise his engaging style, his passionate lectures and his dedication to dirt.
