Aerosol and nanoparticle technology.

Our group is active in three main research areas:

  1. Development of scalable processes to make nanostructured battery cathode materials (funding: Army Research Laboratory) and metal micro-particles for conductive pastes and printable electronics (funding: NSF, DuPont);
  2. Research into air pollution in the Mid-Atlantic region with an emphasis on air pollution emissions relevant to policy (funding: Maryland Department of the Environment, NSF); and
  3. Development of instruments for characterizing exhaled breath aerosol as a non-invasive diagnostic, and for improving understanding of disease transmission by aerosol routes (funding: I-ARPA).
