Collin Mulliner is a cybersecurity researcher and software engineer and spends most of his time working on mobile and smartphones. Collin is interested in vulnerability analysis and offensive security as he believes that in order to understand defence you first have to understand the offence. Collin receives his PhD from the Technische Universitaet Berlin in 2011, and MSc and BSc in Computer Science from UC Santa Barbara and FH-Darmstadt, respectively. Lately, Collin switched his focus to the defensive side to work on mitigations and countermeasures. Collin-coauthored The Android Hacker's Handbook.
