Dan Zachary, Ph.D.

Dan is a faculty member at Johns Hopkins University (Advanced Academic Programs) of the Krieger School of Arts and Science and the Director of the Energy Policy and Climate program.

Dr. Zachary holds a BSc, MSc, and a Ph.D. in Nuclear Physics. His research work was the study of ultra-high energy densities. From 1995 to 1997 he was a post-doc at the European Center for High Energy Physics (CERN, Switzerland) and then lectured mathematics (statistics) at the University of Geneva.  From 2002 to 2006 he was Assistant Professor at the American University of Sharjah (UAE), Associate Professor of Research with Embry-Riddle Aeronautical University, Luxembourg, working closely with the CRP Henri Tudor (Luxembourg) and the University of Luxembourg (2006-2014). Dr. Zachary is author/co-author of nearly a hundred scientific publications including more than 50 peer-reviewed articles and book chapters and over 25 symposium papers, some chosen for international research awards (> 2200 citations). He is associate editor of the Journal of Environmental Modelling and is recognized internationally in the field of energy technology and environmental/climate impact.  

His current research interests are in mathematical and physical modelling, geo-statistics, and earth-atmosphere systems and the connections with anthropogenic emissions.   He has developed a forecasting method for global oscillations (El Nino) and recently has re-developed the technique for short-term air pollution forecasting to be used with ground, airborne and space measurements. In 2014, he published a general mathematical framework for planetary sustainability (Nature, Scientific Reports) and a prediction for climate change (also Nature, Scientific Reports).
