Background

Prior to joining the IRI, Tippett worked at the Center for Weather Prediction and Climate Studies in Brazil and at the Max Planck Institute for Plasma Physics in Germany. Tippett obtained his Ph.D. from the Courant Institute at New York University. Since December 2011, Tippett is an adjunct professor at the Center of Excellence for Climate Change Research, Department of Meteorology, King Abdulaziz University, Jeddah, Saudi Arabia.

Role and Research Interests

Tippett leads the Global Prediction Development effort at the IRI and works on problems related to predictability and the application of statistical methods in climate science.
