Alexander Pavlov
Ph.D., 2001, Pennsylvania State University Lunar and Planetary Lab University of Arizona Tucson AZ 85721 Space Sciences 401 520.626.2083 E-mail Pavlov Dr. Pavlov is interested in the origin and evolution of life on Earth and the possibility of life elsewhere. Specifically, he studies how different planetary environments and climates can promote or hinder life. Venus, Earth and Mars are very similar. However, only Earth has been able to harbor life for billions of years. Is it possible that Mars was warmer and Venus cooler back in the past? What does it mean for a planet to be habitable? What are the major environmental dangers for the existing biosphere? How hard is it to sustain life on a planet for any meaningful period of time? Dr. Pavlov seeks answers to these life-long questions using various computer models and geologic data. His current research interests are: astrobiology, atmospheric evolution, paleoclimate and planetary atmospheres. |
