Loretta Mickley co-leads the Atmospheric Chemistry Modeling Group at Harvard. Her research focuses on chemistry-climate interactions in the troposphere. Key topics of her research include:

  • Impacts of wildfire smoke on human health and regional climate.
  • Effects of climate change on air quality and implications for human health.
  • Influence of aerosol trends on regional climate.
  • Oxidation capacity and fire activity in preindustrial and paleo atmospheres.
