Nicole Heller used to spend her days on hands and knees trying to tease apart the secret world of Argentine ants—an invasive insect that has risen to worldwide prominence thanks to its ability to hitch rides on human trade routes. But after several years debating specialized questions about ant behavior with colleagues, Heller, who spent her formative years in Palo Alto, California, started to yearn for something bigger. “As much as I love ants, I felt like I needed to focus on broader conservation issues,” she says.
