As a Staff Scientist, the successful candidate will support Epsilon’s air quality dispersion modeling practice, working on various environmental consulting tasks, including:

  • Dispersion modeling, using AERMOD and other models as appropriate, to support permitting of new and modified commercial, industrial, and energy projects;
  • Specialty atmospheric modeling, including accidental release, fogging and icing, air intake re-entrainment, transportation source, and deposition modeling;
  • Analyzing baseline public health data, comparing public health conditions to baseline, identifying metrics and factors that could suggest a disproportionate burden on Environmental Justice communities, and working with Epsilon senior staff to identify mitigation measures; and
  • Working with Epsilon’s team to provide seamless air quality regulatory permitting and compliance consulting.

Projects may include new and existing power plants and industrial facilities, new onshore and offshore wind facilities, and commercial real estate developments.

The Staff Scientist will be expected to grow into client interaction, task management, project management, public outreach, and business development roles.
