Dr. John Cromwell Mather is an American astrophysicist, cosmologist and Nobel Prize in Physics Laureate for his work on the Cosmic Background Explorer Satellite (COBE) with George Smoot.
This work helped cement the big-bang theory of the universe. According to the Nobel Prize committee, “the COBE-project can also be regarded as the starting point for cosmology as a precision science.”
Dr. Mather is a senior astrophysicist at the NASA Goddard Space Flight Center (GSFC) in Maryland and an adjunct professor of physics at the University of Maryland College of Computer, Mathematical, and Natural Sciences. In 2007, Dr. Mather was listed among Time magazine’s 100 Most Influential People in The World. In October, 2012, he was listed again by Time magazine in a special issue on New Space Discoveries as one of 25 most influential people in space.
Dr. Mather is also the project scientist for the James Webb Space Telescope (JWST), a space telescope scheduled to be launched to Lagrange Point L2 in 2020.

Dr. Mather also serves as a senior member in many educational committees and board of directors: National Academy of Sciences committee on GP-B in 2003; Board of Directors, Center for Excellence in Education in 2008; National Academy of Science committee, “Conceptual Framework for New Science Education Standards” in 2010 – 2011; NAS Board on Science Education in 2015 -.

Hon. Professor T.H. Lee Williams

Senior Vice President for Research, 1999 -2009,

Graduate College Dean, 1999 – 2016

Full Professor

University of Oklahoma, Norman,

Ph.D. in Remote Sensing, University of Bristol, United Kingdom of British, in 1977

Dr. Williams is a world-known expert in the fields of Remote Sensing and Radar Image Processing.
Williams received his Ph.D. in 1977 from the University of Bristol, United Kingdom of British. After graduation, he taught in the geography and electrical engineering departments at the University of Kansas. During this time he also conducted research at the Radar Systems and Remote Sensing Lab and as a consultant for Unesco at the Haryana Agricultural University in India. He joined the University of Oklahoma in 1986 as an associate professor in geography and director of the Geoscience Remote Sensing Group.
Dr. Williams was appointed as Senior Vice President for Research and Dean of the Graduate College in 1999. Dean Williams sought to create an environment at the university that struck a balance between the demands of teaching and pursuing academic research and publication. By developing expanded funding for research professorships, decreasing time to graduation and tracking student progress through degree programs, Dean Williams has worked to ensure that the Graduate College produces the highest caliber graduates and ground-breaking research.
Dean Williams also seeks to emphasize the underlying academic principles and standards that run throughout the University. While the demands of each department vary greatly, the ultimate goal of producing well-rounded students and high level scholarship is the same in all. By focusing on the academic standards behind each petition to the Graduate College, Dean Williams has worked to create a consistent set of standards throughout the university. He and the staff of the Graduate College have worked to restructure their regulations and procedures to ensure that the departments have the resources and support to attract, educate and, ultimately, graduate students.

One of the most successful initiatives undertaken by Dean Williams has been the development of fellowship programs. Over the last decade, the number of Alumni Fellows at the university has nearly doubled. The achievements of these top flight students have, in turn, increased the ability of the departments to raise additional educational and research funding. Dean Williams’ program to obtain funds from the OU Foundation to match private donations for fellowships has effectively doubled the number of new fellows funded in recent years.
Dr. Williams was Dr. Martin Ma’s Advisor when Dr. Ma was a Doctor Student, Post-Doctor Fellow, and Research Scientist at the University of Oklahoma from 1990 – 1994.
