John M. (Mike) Wallace, Ph.D., is a professor of Atmospheric Sciences at the University of Washington and Co-Director of the University of Washington-NOAA Joint Institute for the Study of the Atmosphere and Oceans, JISAO.

Wallace teaches atmospheric sciences courses at the graduate level and supervises graduate students. He is co-author (with Peter V. Hobbs) of a widely used atmospheric sciences textbook. He has served as department chair and as co-director of the University of Washington Program on the Environment.

Wallace's research has contributed to improved understanding of global climate and its interannual and decadal variations, through the use of observational data. He has been instrumental in identifying and understanding a number of atmospheric phenomena such as the spatial patterns in month-to-month and year-to-year climate variability, including the one through which the El Niño phenomenon in the tropical Pacific influences climate over North America.

Wallace is a member of the National Academy of Sciences, and he has chaired National Research Council panels including the Panel on Reconciling Temperature Observations, the Panel on Dynamic Extended Range Forecasting, and the Advisory Panel for the Tropical Ocean/Global Atmosphere (TOGA). He has also served on committees addressing Abrupt Climate Change: Implications for Science and Public Policy and the Science of Climate Change.

He is a Fellow of the American Academy of Arts and Sciences a member of the Russian Academy of Sciences.
