Heather Mahalik is the forensics expert of choice for law enforcement and intelligence on high profile cases from child exploitation to Osama Bin Laden’s digital media. Her book, Practical Mobile Forensics, is a best-selling guide to forensics. She leads SANS’ popular Advanced Smartphone Forensics course. “I spend almost 90 percent of my day job cracking into tough stuff my experience flows into the classroom.” And it pays off. Mahalik’s students frequently reach out to thank her for her course, saying they helped put criminals away for many years. "Nothing compares to knowing that the effort you put into developing and teaching a course makes the world a better and safer place.”
