the impact of turbulence on aircraft; development of new systems to alert aircraft to areas of turbulence

Williams is a mathematician who seeks to better understand how aircraft can avoid potentially dangerous regions of turbulence. He helped create a mathematical method that uses information from Doppler radars to obtain real-time snapshots of turbulence for aircraft flying over the continental United States. More recently, he has focused on combining artificial intelligence techniques with satellite observations and computer weather models to predict storms and other potential areas of turbulence over the oceans.
