Forensics
Arturo Casadevall has zero training in forensic science—the techniques used in law enforcement and the courtroom to link individuals to crimes. For most of his career, the microbiologist at Johns Hopkins University in Baltimore, Maryland, paid the discipline little attention, but he did notice the field-shaking 2009 report from the National Academy of Sciences (NAS), which found that many forensic techniques, from fingerprint comparisons to bloodstain pattern analysis, lacked a firm scientific footing. “I remember reading [NAS] about this and I said, ‘Oh my God, I thought fingerprints had been validated,’” he remembers.
