BA (Geography) - University of Toledo - 1986
MA (Geography) - University of Oklahoma - 1994
Ph.D. Student (Geography) - University of Oklahoma - 1998+

Research Interests:
I have an employment background in environmental regulation (Superfund) and emergency response with research interests in natural hazards, environmental risk, climatology, and medical geography focused primarily in the Midwest and Great Plains of the USA. My emphasis at this time is on severe weather warning systems and human ecology of weather risk with secondary interests in climatology and societal attitudes toward weather risk and control (such as cloud seeding). My MA Thesis was titled "Tornado Hazards, Coping Styles and Warning Systems Under the Modernized National Weather Service." Immediately following the 1999 Central Oklahoma Tornado Outbreak, I conducted field surveys of more than 300 persons regarding their actions during the storm, mode and lead time of warnings, available shelter, and impact of future risk attitudes. This information is currently being processed for formal publication. I am active as an Emergency Management Volunteer in Central Oklahoma and have been a Mobile Mesonet tornado intercept driver since 1995 for VORTEX-STEPS-IHOP-etc., with the National Severe Storms Laboratory and CIMMS/OU. I am single and have lived in Oklahoma most of the last 15 years. I am an avid Detroit Red Wings fan and originally from Toledo, Ohio.

Expertise and Research Interests

Dr. Susan Postawko

Assistant Professor of Meteorology 

B.S., 1977, University of Missouri (St. Louis); Ph.D., 1983, University of Michigan. Assistant Professor of Meteorology

Expertise and Research Interests
Dr. Postawko's interests include radiative transfer in planetary atmospheres; atmosphere-surface interactions; volatile history of the planets; early and present climates of Earth and Mars; and climate evolution of the terrestrial planets. Current projects include modeling the effects on martian climate history of sulfur dioxide released by volcanoes, and the fate of water vapor released by Martian volcanoes. Dr. Postawko is co-coordinator of the Schools of the Pacific Rainfall Climatology Experiment (SPaRCE), a research/education project to study climate change in the Pacific, and teach students in various Pacific island nations about climate and the implications of global change. Dr. Postawko was named Outstanding Professor in the College of Geosciences by the University of Oklahoma Student Association in 1994 and 1996. In addition to being a faculty member in the School of Meteorology, she also serves as the Assistant Director of the NASA/Oklahoma Space Grant Consortium.
