AMS Endowed Lectures

The Alan Goldman Lecture Series in Operations Research was established in 1999 to honor the highly respected professor when he was named Professor Emeritus at JHU.

About Alan J. Goldman

Alan J. Goldman was an expert in operations research – the use of mathematics to improve decisions on the design and operation of complex systems – whose favorite application areas included facility siting, transportation systems, and mathematical game theory. Goldman received his BA from Brooklyn College in mathematics and physics in 1952. He earned his MA and PhD in mathematics from Princeton University in 1954 and 1956, respectively. His dissertation area was topology, and the title of his dissertation is A Cech Theory of Fundamental Groups and Covering Spaces. From 1956 to 1961 he was an evening lecturer at American University and Catholic University of America, but his principal pre-JHU affiliation was with the National Bureau of Standards (now the National Institute of Standards and Technology), where he was founder and chief of operations research and also deputy chief of applied mathematics. Goldman joined Hopkins in 1979; earned the status of Professor Emeritus in 1999 and continued to teach until his death in 2010.

The Acheson J. Duncan Lecture Series
In 1986, an anonymous donor established the Acheson J. Duncan Distinguished Visitor Fund to honor the internationally recognized leader in quality control and industrial statistics. The endowment supports an annual visit and lecture by a distinguished mathematical scholar.

About Acheson J. Duncan

Acheson J. Duncan spent 25 years as a faculty member at Johns Hopkins. His extensive writings in the field include the text, Quality Control and Industrial Statistics, published in 1952 and now in its fifth edition with several international translations. The late dean of the Whiting School of Engineering, Robert H. Roy noted that Duncan and his work were revered in Japan, where Duncan frequently lectured in the years following World War II. A native of New Jersey, Duncan received his PhD in economics from Princeton in 1936, and was a faculty member there for 13 years before coming to Hopkins. Duncan died in 1995 at age 90.

The John C. and Susan S. G. Wierman Lecture Series in Air Quality Data Analysis features talks on developments in air quality data analysis that are relevant for policy development. It seeks to bring together faculty and researchers in engineering and natural sciences with state and local air quality officials, to enhance understanding and stimulate collaboration on important air quality issues. The lectures are intended to showcase new developments, to encourage the quantitative analysis of scientific issues related to air quality, and to elucidate the policy implications of recent research. The lecture series was established with a permanent endowment by Prof. John C. Wierman and Susan S. G. Wierman.

About the Sponsors

John C. Wierman, a professor of Applied Mathematics and Statistics at Johns Hopkins University since 1981, served as department chair from 1988 to 2000. The founder of the W. P. Carey Program in Entrepreneurship & Management, he was director of the program and its successor, the Center for Leadership Education, from 1996 until 2009. His mathematical research is published in probability, discrete mathematics, and statistics journals, with applied articles in physics, computer science, molecular biology, education, and business journals. He received his BS. and PhD from the University of Washington and is a Fellow of the Institute of Mathematical Statistics and the Institute of Combinatorics and its Applications.

Susan S.G. Wierman was executive director of Mid-Atlantic Regional Air Management Association from 1996 to 2017, where she worked to improve regional air quality. She earned urban planning degrees from the University of Washington, and a certificate in Continuing Engineering Studies from Johns Hopkins University. She is a Fellow of the international Air and Waste Management Association, and was the 2012 recipient of its S. Smith Griswold Outstanding Air Pollution Official award.
