Research Description
My main research focus is the separation of droplets and ice crystals formed in clouds using virtual impaction technique. In our lab we have two cloud chambers, a warm and a cold cloud chamber. With these chambers we are able to test different aerosol particles on their efficiency to generate droplets and ice crystals under well controlled, atmospheric like conditions. I am also working on future virtual impaction applications by using 3D printed prototypes of virtual impactors and aerodynamic lenses.
