Dr. Krider currently teaches courses on physical meteorology (ATMO 451/551) and atmospheric electricity (ATMO/ECE 489/589) at The University of Arizona.
Dr. Krider is known world-wide for his work on lightning and thunderstorm electricity. He led the group that developed the first gated, wideband magnetic direction-finders that are now the basis of the U.S. National Lightning Detection Network. Dr. Krider is a Fellow of the American Geophysical Union and the American Meteorological Society and a former Co-Chief Editor and Editor of the Journal of the Atmospheric Sciences; he is also past President of the International Commission on Atmospheric Electricity.
Research Interests: Lightning and atmospheric electricity
