CFAN’s consultants provide broad expertise in information technology, decision support, business, law, economics and policy.

CFAN’s leadership team includes:

Judith Curry

President and Founder 

Judith Curry is President and co-founder of CFAN.  Following an influential career in academic research and administration, Curry founded CFAN to translate cutting-edge weather and climate research into forecast products that support the mitigation of weather and climate risk for public and private sector decision makers.

Curry received a Ph.D. in atmospheric science from the University of Chicago and B.S. in Meteorology from Northern Illinois University. She has held faculty positions at the Georgia Institute of Technology, the University of Colorado Boulder, Penn State University, and Purdue University.  She is a Fellow of the American Meteorological Society, the American Association for the Advancement of Science, and the American Geophysical Union.

Curry is actively engaged at the intersection of science and public policy. She has recently served on the NASA Advisory Council Earth Science Subcommittee, the DOE Biological and Environmental Research Advisory Council and the National Academies Climate Research Committee and the Space Studies Board. She is frequently called upon to give Congressional testimony and serve as an expert witness on matters related to weather and climate.

Peter Webster

Chief Scientist and Founder

Peter Webster is Chief Scientist and co-Founder of CFAN. His research on tropical meteorology and climate dynamics has been applied developing flood, heat wave, and tropical cyclone forecasts for the monsoon regions in South Asia. He has actively worked with developing countries and development banks to support tactical adaptation strategies using forecasted extreme weather events.

Webster received a Ph.D. in Meteorology from MIT.  He has held faculty positions at Georgia Institute of Technology, University of Colorado, Penn State University and the University of Washington. From 2000-2004, Webster was CEO of Aerosonde North America, a company that manufactured small unmanned aerial vehicles.

Webster’s research has been recognized by the Jule Charney Award and the Carl Gustav Rossby Research Medal from the American Meteorological Society, the Adrian Gill Award and Mason Gold Medal from the Royal Meteorological Society, and the International Award from the American Geophysical Union, and the International Prize for Water.  Webster recently served as President of the American Geophysical Union Atmospheric Sciences Section.

Violeta Toma

Vice President, Forecast Product Development

Violeta Toma oversees all of CFAN's forecast product development.  She leads the overall effort for CFAN’s temperature forecast products, including CFAN’s innovative products that predict heat waves, cold waves, and heat stress.  She is also the lead the for CFAN’s subseasonal and seasonal forecasts.

Prior to joining CFAN in 2010, she was an air quality consultant at Trinity Consulting. Her expertise included Air Dispersion Modeling, New Source Review (NSR) permitting and regulatory applicability analyses for a variety of industries including Renewable Electricity Generation.  Prior to coming to the U.S., Toma was a Meteorologist at the National Institute of Meteorology and Hydrology, Romania.
