DOCTOR DANIEL ZACHARY | Physicist (MIT) | Program Director, Sr Lecturer, Energy Policy & Climate Program at Johns Hopkins University, DC

Daniel (Dan) S. Zachary, Ph.D., is the Program Director for the Energy Policy and Climate Program at Johns Hopkins University. For nearly 2 decades, Dan has been working in the field of policy support (energy and climate impact). He has developed models and has provided input for authorities at the local, national, and international level.

Dan holds a Ph.D. in Nuclear Physics (energy density modeling), an MSc in Space/Atmospheric Physics, and a BSc in Physics (gravity wave detection) all from MIT (the Massachusetts Institute of Technology.) From 1995 to 1997 he was a Post-doctoral fellow 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 teaching environmental physics (Sharjah, UAE) and was nominated Associate Professor of Research with Embry-Riddle Aeronautical University (Luxembourg), working closely with the CRP Henri Tudor and the University of Luxembourg on air quality, community noise and geo-spatial problems linked to national and European policy. Along with his academic position, he served as Research and Development Manager at the CRP Henri Tudor and lectured at the University of Luxembourg.

Dr. Zachary is author/co-author of nearly 100 scientific publications including peer-reviewed articles, book chapters and symposium papers, some chosen for international research awards. He is associate editor of the Journal of Aerospace Operations and the Journal of Environmental Modeling and Assessment. Dan’s academic research has focused on mathematical and physical modelling for policy support, geo-statistics, earth-atmosphere systems (connections with anthropogenic emissions), global energy sustainability and general (statistical) forecasting methods. Finally, he has published a general mathematical framework for planetary sustainability, (Nature, Scientific Reports, 2014).
