Eugene D. Hahn - Biographical Sketch

Dr. Gene Hahn is a Full Professor in the Department of Information and Decision Sciences at Salisbury University. His research interests include management decision making, Bayesian inference, and international operations including offshoring and global supply chain management. He has authored the book "Bayesian Methods for Management and Business: Pragmatic Solutions for Real Problems". He is also a Certified Analytics Professional (INFORMS) -- contact him about your business analytics project needs. Dr. Hahn was the founding Director of Salisbury University's first Innovation Lab where students could develop their own products using 3D printing and Arduino microcontrollers. He has also started a Bayesian book review blog for business and management readers here.
