Hawkins Research lab - Atmospheric aerosol


Atmospheric aerosols are suspensions of tiny liquid and solid particulates found all over the world in varying size, shape, composition, and concentration. These particles come from breaking waves, volcanoes, wildfires, cars, coal burning, and the pine fresh smell of forests.

Atmospheric scientists are interested in these particles for two main reasons: (1) particles are hazardous to human health and can lead to asthma and cardiovascular related problems and (2) particles play a vital role cloud formation and in the energy balance of our planet.

Research in the Hawkins Lab focusses on the sources, composition, and transformations of aerosol particles as they relate to our climate, specifically their organic components. Specifically we are interested in the complex set of reactions that transform gas phase pollutants into particles during the formation and evaporation of fog and cloud droplets.

welcome to the world of particulate matter

“I say!” murmured Horton. “I’ve never heard tell

Of a small speck of dust that is able to yell.

So you know what I think? I think there must

Be someone on top of that small speck of dust!

Some sort of creature of very small size,

too small to be seen by an elephants eyes”

-From Horton Hears A Who by Dr. Seuss
