Natalia Andronova is a research scientist in the Climate Research Group of the Department of Atmospheric Sciences at the University of Illinois at Urbana-Champaign. Her research interests are broadly defined, but center around the fields of global and regional climate change, interactions between climate and the chemical composition of atmosphere, feedbacks in the climate/chemistry system, and the response of the climate/chemistry system to different radiative forcings, both of natural and anthropogenic origin. Her education covers a large area of science, starting from mathematics (B.S., Leningrad State University, Russia), fluid mechanics (M.S. Leningrad State University, Russia), and meteorology and geophysics (Ph.D., Main Geophysical Observatory, Russia). Her achievements are the development of a systems approach to study the complicated climate/chemistry system under anthropogenic pressure; in extending the method of Cause and Effect Analysis (CEA) to analyze geophysical phenomena's feedbacks, sensitivity and stability; in estimation of the role of different factors in climate change using both simple climate models and more complicated models of the Earth system.
