John Fasullo, Project Scientist III


Dr. J.T. Fasullo is a Project Scientist in the Climate Analysis and Climate Change Research Sections at NCAR and a Research Associate in the ATOC Department at the University of Colorado. He is involved in research aimed at understanding climate variability and change, and community activities such as the Climate Data Guide and Climate Variability Diagnostics Package. He collaborates with Drs. Kevin Trenberth, Bette Otto-Bliesner, Steve Nerem and others. He obtained his B.S. in Applied and Engineering Physics from Cornell University and his Ph.D. from the University of Colorado under the supervision of Dr. Peter J. Webster.

His activities include:
