Soot particle close up

Soot particles 150 nm across

We are interested in experiments that uncover new phenomena, using modeling  as a tool for interpreting and interpolating experiments. Over the years,  our group has studied the transport properties of fractal aerosols, mixing of pollutants in traffic tunnels, formation and deposition of particles in supercritical water  and novel fuel-injection systems.

Our work falls into three major areas:

During the SARS CoV2 pandemic, we’ve been working on several issues related to airborne transmission of COVID-19.  Our work on masks is relatively complete, while work on the relation between particle size and protective measures is just starting, and my comments on these pages on self-contamination from your mask is just “reasoned speculation”.
