She is also a professor in the Department of Earth System Science at Stanford University. Prior to joining Carnegie, she was the Frank and Brooke Transue Faculty Scholar and associate professor at the University of Michigan. Dr. Michalak studies the cycling and emissions of greenhouse gases at urban to global scales—scales directly relevant to informing climate and policy—primarily through the use of atmospheric observations. She also explores climate change impacts on freshwater and coastal water quality via influences on nutrient delivery to, and on conditions within, water bodies. Her approach is focused on the development of spatiotemporal statistical data fusion methods that optimize the use of limited in situ and satellite data. She is the lead author of the U.S. Carbon Cycle Science Plan, a former editor of the journal Water Resources Research, chair of the scientific advisory board for the European Integrated Carbon Observation System, member of the OCO-2 science team, and former member of the NASA Advisory Council Early Science Subcommittee. Dr. Michalak is the recipient of the Presidential Early Career Award for Scientists and Engineers (nominated by NASA), the NSF CAREER award, and the Leopold Fellowship in environmental leadership, among other recognitions.
