Daniel Zachary

Program Director and Senior Lecturer, Energy Policy and Climate Program
Krieger School of Arts and Sciences Advanced Academic Programs

d.s.zachary@jhu.eduFaculty Website

Research Areas:
  • Integrated assessment (IA) modeling – energy infrastructure and air quality models: building coupled (meta-models) and using them to better understand the built environment, including: projecting urban/regional energy infrastructure growth and subsequent air pollution and human impact to inform policy support measures. 
  • Smart grid applications in terms of long-term policy analysis. 
  • Statistical techniques to expand urban IA models to study regional and global energy systems with their subsequent pollution impact.
Keywords: Air pollution, Energy infrastructure, Smart grid, Urban sustainability
