Dr. Vishwanath studies the “people problem” of cybersecurity.

His research focuses on improving individual, organizational, and national resilience to cyber attacks by focusing on the weakest links in cyber security—all of us Internet users.

His particular interest is in understanding why organizational insiders willingly exfiltrate sensitive organizational data; why people become unintentional insiders by falling prey to social engineering attacks that come in through email and social media; and on ways we can harness this understanding to secure cyberspace. He also examines how various groups—criminal syndicates, terrorist networks, hacktivists—utilize cyberspace to commit crimes, spread misinformation, recruit operatives, and radicalize others.

Dr. Vishwanath has consulted for major corporations and governments on issues ranging from cybersecurity to consumer protection. He was formerly the Research Director (1998-2014) at Goldhaber Research Associates (GRA), and currently serves as the President and Chief Technologist of Avant Research Group (ARG)—a cyber security research and advisory firm. Through the firm, Dr. Vishwanath works with regional and international research clients spanning government, education, healthcare, finance, marketing, public relations, market research, sports, media, and real estate development, on issues concerning user behavior and cyber security.

Dr. Vishwanath is an alumnus of the Berkman Klein Center at Harvard University. His research on improving cyber resilience against online social engineering has been funded by the National Science Foundation. He has written and published over two-dozen articles on technology users and cybersecurity issues and his research has been presented to principals at national security and law enforcement agencies around the world. His research and views on the science of cybersecurity have also been featured on CNN, the Washington Post, Wired Magazine, USA Today, Politico, Bloomberg Business Week, Consumer Reports, Scientific American, and hundreds of other national and international news outlets. He also serves on a distinguished expert panel for the NSA’s Science of Security & Privacy research directorate.
