My work focuses on cybercrime, fraud, investigations, financial crime, and security, combining academic research with professional investigative experience.

Before entering academia, I held senior positions in fraud prevention, corporate security, and investigations, including serving as Senior Vice President of Fraud Surveillance at Citigroup and Director of Corporate Security & Investigations at Morgan Stanley. Earlier in my career, I conducted investigations for the New York State Office of the Attorney General and the New York City Department of Investigation.

I am a Licensed Private Investigator and Certified Fraud Examiner, as well as the author and editor of books on investigations, fraud, and security. My research and professional expertise have been featured in more than 40 national and international media outlets, including The New York Times, The Wall Street Journal, CBS News, NPR, Bloomberg, and USA Today.

I serve on the Board of Directors of the World Association of Detectives and am a past president of the New York Chapter of the Association of Certified Fraud Examiners.
