Asteroid monitored from outer space to ground impact. Mark Boslough is an expert on planetary impacts and global catastrophes, Boslough's work on airbursts challenged the conventional view of asteroid collision risk and is now widely accepted by the scientific community. Boslough received a BS in physics from Colorado State University and his MS and PhD in applied physics from the California Institute of Technology. His graduate research focused on impact physics, geophysics, shock wave properties, and high-pressure equations of state of rocks and minerals. In recent years Mark has led a variety of projects in other domains, including climate modeling and evolutionary computing. Renewed interest in his past research on cometary and asteroid impacts has brought him back into that field armed with the power of the current generation of supercomputers and codes. Boslough is a vocal critic of pseudoscience and anti-science and has written about climate change denial in the Skeptical Inquirer in reference to "Climategate" conspiracy theories. He is also active in uncovering scientific misconduct.
