Mark J. Nigrini, born in Cape Town, South Africa, is a faculty member at the College of Business and Economics at West Virginia University in Morgantown in the US state of West Virginia. Nigrini is best known for his work on using Benford's Law as an auditing and accounting tool to detect anomalies in company data. He is the author of Forensic Analytics which describes tests to detect fraud, errors, estimates, and biases in financial data and he is also the author of Benford's Law. Benford’s Law gives the expected patterns of the digits in tabulated data and it has been used by auditors and scientists to detect anomalies in tabulated data.
His academic papers have been published in Auditing: A Journal of Practice and Theory, The Journal of the American Taxation Association, The Journal of Forensic Accounting, The Journal of Emerging Technologies in Accounting, and others. Other applied papers have been published in journals such as Mathematical Geology, The International Journal of Mathematics and Mathematical Sciences, and The International Journal of Algebra. He has also published a hybrid forensic-medical study in the highly rated journal Hepatology. His practitioner papers have been published in journals such as IEEE Potentials, Internal Auditor, and the Journal of Accountancy. Nigrini serves on the Executive Editorial Board of the International Journal of Disclosure and Governance  and also of the Journal of Forensic & Investigative Accounting.
Nigrini's forensic work has been referenced in the national media including The Financial Times, The New York Times, The Wall Street Journal,The Globe and Mail, and New Scientist. His work has also been featured in foreign language publications such as Der Spiegel. His radio interviews have included the BBC in London, and NPR in the United States. His television interviews have included appearances on NBC's Extra and The Investigation Discovery Channel for their series on Evil Twins.
In October 2013 Nigrini delivered the prestigious Sufrin Lectureship in Accounting at the University at Buffalo. In April 2014 Nigrini presented a pre-conference workshop in Palm Springs, California at the annual conference of the National Association of Purchasing Card Professionals on using Forensic Analytics to detect purchasing card fraud, errors, waste and abuse. He also presented a keynote talk on Benford's Law at the same conference. In June 2014 he presented a pre-conference workshop in San Antonio, Texas at the annual global conference of the Association of Certified Fraud Examiners on Benford's Law and Analytical Fraud Detection Techniques. In October, 2018 he presented two break-out sessions and one general session at the 27th Annual Conference of the International Association of Airline Internal Auditors held in Panama City, Panama. 
In August 2014 Nigrini published an article, Lessons from an $8 million fraud, with Nathan J. Mueller who stole $8.45 million from his employer, an insurance company, over a four-year period. In the article Mueller describes his fraud scheme, how he explained his newfound wealth in the form of expensive cars, watches, nightlife entertainment, and Las Vegas gambling trips, to his wife and friends, and ultimately how he was caught. Mueller served his sentence at Federal Prison Camp, Duluth, a minimum security federal prison. He was released on February 27, 2015. In the article Nigrini reviews the preventive and detective anti-fraud measures that could have detected the multimillion-dollar fraud long before it was detected, quite by chance, after four years. The Journal of Accountancy is the flagship publication of the American Institute of Certified Public Accountants. In August, 2015 the Journal of Accountancy announced that Nigrini and Mueller had won the prestigious Lawler Prize for the best article in 2014.
Nigrini has a B.Com (Hons) degree from the University of Cape Town, an MBA degree from the University of Stellenbosch, and a PhD degree from the University of Cincinnati. In addition to his academic credentials, Nigrini passed the Chartered Accountant (South Africa) exam in 1981 and his early accounting career included time with Peat, Marwick, Mitchell & Co. (now KPMG) and as a divisional accountant. Nigrini has served as an expert witness and has done consulting engagements for large international organisations and government departments at the state level.
