Erwin Saniga is the Dana Johnson Professor of Information Technology and Professor of Operations Management in the Department of Business Administration at the University of Delaware. Professor Saniga has published over 50 papers in statistics or mathematical modeling in business, statistics, engineering or medical journals. A recent paper in IIE Transactions won the best paper award for 2008 in the area of Quality and Reliability Engineering.
Professor Saniga has also presented a number of papers at Conferences of The American Statistical Association, The Institute for Management Sciences and The Operations Research Society, The American Accounting Association, The Western Finance Association, The Decision Sciences Institute, The Irish Mathematical Society World Congress on Computation and Applied Mathematics, and various university seminar series including those at Drexel University, Hollins College, George Washington University, Indiana University, Penn State , and the Jerusalem Studio School. He has been an invitee for the triennial International Workshop on Intelligent Statistical Quality Control since 1980.
He has consulted for many organizations in the areas of statistics, process improvement, technology, and operations management and has won awards for teaching and research at the University of Delaware.
His recent teaching has been on Technology Project Management where teams of students actually design and implement information technology solutions or process improvement solutions for local organizations.
