János D. Pintér is a researcher and practitioner with over four decades of experience. His professional interests are related to computational optimization, data analytics, and operations research. His more specific main area of expertise is nonlinear optimization, including model, algorithm and software development, with a broad range of applications.

He received his M.Sc. summa cum laude in the area of Applied Mathematics/Operations Research from Eötvös Loránd University (ELTE), Hungary; Ph.D. in Probability Theory/Stochastic Optimization from Moscow State University; and D.Sc. in Mathematics/Global Optimization from the Hungarian Academy of Sciences.

As of 2019, Dr. Pintér wrote and edited ten books: links to his internationally published books are provided under the Research entry. He is also the author/co-author of more than 200 articles, book chapters, proceedings contributions, book reviews, and technical reports. His monograph titled Global Optimization in Action received the 2000 INFORMS Computing Society Prize for Research Excellence.

Among other professional affiliations, he serves or served on the editorial board of the Journal of Global Optimization, the Journal of Applied Mathematics and Decision Sciences, Algorithmic Operations Research, and the International Journal of Modeling, Identification and Control. Currently, he is an editor of the book series SpringerBriefs in Optimization. He also served as Global Optimization vice-chair of the INFORMS Optimization Society, and as a member (later chair) of the Managing Board of EUROPT. Currently, he is a member of the Canadian and the Hungarian Operations Research Societies, INFORMS, and EUROPT. 

During his professional career, Dr. Pintér received research grants, awards and fellowships in Australia, Canada, Hungary, Netherlands, the United States, and elsewhere. He has worked and presented lectures in about 40 countries of the Americas, Europe, the Middle East, and the Pacific Region. Among other institutions, from 1973 to 1991 he worked as a research scientist at ELTE and the Water Resources Research Centre (Hungary), the International Research Institute for Management and Control (Russia), and the Institute for Inland Water Management and Wastewater Treatment (Netherlands). Between 1991 and 2007, he was an Associate Professor and later Adjunct Professor at Dalhousie University (Canada). He also worked as a Visiting Professor at Bilkent and Özyeğin Universities in Turkey from 2008 to 2011, before returning to Canada. Until 2016 he worked as an Associate Professor at Saint Mary’s University (Canada), and was Adjunct Professor at Özyeğin University.

Dr. Pintér is the founder/owner of PCS Inc. (Canada), a consulting company he has been running since 2004. In this capacity, he is the principal developer of the LGO nonlinear optimization software, with links optimization modeling languages, and scientific-technical computing systems. These software products have been in use by hundreds of academic, business, research, and government organizations. For further details, visit his web site.

In August 2016, Dr. Pintér joined the Department of Industrial and Systems Engineering at Lehigh University as a Professor of Practice. Since that time, he has been teaching the following courses:

Applied Engineering Statistics (ISE 121)

Introduction to Stochastic Models in Operations Research (ISE 230)

Optimization Models and Applications (ISE 316 and 426)

Engineering Statistics (ISE 328)

Financial Optimization (ISE 347 and 447)

Introduction to Engineering Mathematics (ISE 357)
