The title of Distinguished Professor denotes a faculty member who is in the top 5 percent of his or her field throughout the world. Recipients are considered preeminent in their fields based on seminal contributions to their disciplines.

The Chancellor of the Texas A&M University System grants the title to the successful nominees.

All four of the College of Geosciences' Distinguished Professors are also Fellows in the American Geophysical Union.


Gerald North

Dr. Gerald North

Distinguished Professor
Departments of Atmospheric Sciences and Oceanography

Appointed September 1, 1986

Dr. Gerald North is one of the leading authorities on climate change. His contributions include groundbreaking research on climate models, atmospheric statistics, and satellite mission development. He has been holder of the Harold J. Haynes Endowed Chair in Geosciences and has served as department head in Atmospheric Sciences. Among his many publications are the recent books, Impact of Global Warming in Texas (rev. 2nd edition, 2011) and An Introduction to Atmospheric Thermodynamics (2009). The American Meteorological Society awarded him the Jule G. Charney Award in 2008.


Worth Nowlin

Dr. Worth Nowlin

Distinguished Professor Emeritus
Department of Oceanography

Appointed September 1, 1987

Dr. Worth Nowlin led development of the Global Ocean Observing System and the Gulf of Mexico Coastal Ocean Observing System. He is a Fellow of the American Geophysical Union. He twice received the Texas A&M Association of Former Students Distinguished Achievement Award for Research. He was awarded the Antarctic Service Medal of the United States and the AGU Ocean Science Award, and was appointed Admiral in the Texas Navy. He is former Department Head of Oceanography, Texas Sea Grant Director, Associate Dean of Geosciences and founding Director of the Texas Center for Climate Studies.


Robert Duce

Dr. Robert Duce

Distinguished Professor Emeritus
Departments of Oceanography and Atmospheric Sciences

Appointed June 1, 2004

Dr. Robert Duce is both a distinguished scientist and an international leader in geosciences. His research focuses on the chemical cycles of pollutant and natural substances in the global atmosphere and the impact of air-sea exchange on the atmosphere and ocean. He is former dean of the College of Geosciences. He is a Fellow of the American Association for the Advancement of Science, American Geophysical Union, American Meteorological Association and the Oceanography Society and received the Rosenstiel Award. He is the chair of the National Academy of Sciences Ocean Studies Board.


Renyi Zhang

Dr. Renyi Zhang

Distinguished Professor
Department of Atmospheric Sciences

Appointed September 1, 2014

Renyi Zhang joined the faculty in Texas A&M’s Departments of Atmospheric Sciences of College of Geosciences (1997) and Chemistry of College of Science (2007). He earned a Ph.D. from MIT and completed postdoctoral work at Caltech/NASA Jet Propulsion Laboratory. He is holder of the Harold J. Haynes Endowed Chair in Geosciences. His early research contributed to the understanding of stratospheric ozone depletion and formation of the “Antarctic Ozone Hole”?. His research at Texas A&M has led to breakthroughs and paradigm shifts in several atmospheric fields—photochemical oxidation of hydrocarbons; formation, growth, and properties of aerosols; urban and regional air pollution; ambient measurements of trace gases and aerosols; and assessment of aerosol-cloud-climate interaction—and provided critical insights into the impacts of human activities on the environment, weather, and climate. He has published more than 160 papers in peer-refereed journals. Currently, Zhang serves as director of the Center for Atmospheric Chemistry and the Environment at Texas A&M, chairs the American Meteorological Society’s Atmospheric Chemistry Committee, is editor of the Journal of Geophysical Research”“Atmospheres and Journal of the Atmospheric Sciences, and is a member of the International Commission on Atmospheric Chemistry and Global Pollution. He has received numerous awards, including honorary professorships at Peking University and Fudan University in China, the Outstanding International Collaboration Researcher Award from the China National Science Foundation, The Association of Former Students Distinguished Achievement Award—Research, the Bush Excellence Award for Faculty in International Research, and the Cheung-Kong Distinguished Scholar Award from the Ministry of Education”“China. He is a Fellow of the American Geophysical Union.
