Research Interests
My current research interests include aerosols and their potential for heterogeneous ice nucleation in the atmosphere. I am currently working towards the development of a Continuous Flow Diffusion Chamber (CFDC) to study ice nucleation. The CFDC will initially be used in the ISDAC aircraft campaign in Barrow, Alaska during spring 2008, and in the future it will also be used for laboratory experiments on soot. I am also interested in studying the mechanisms of heterogeneous ice nucleation, specifically contact and immersion freezing. I have carried out several experiments using the Ice Microscope apparatus using various ice nuclei such as authentic desert sand samples collected from Saudi Arabia, Peat, Volcanic Ash, Soot, Silver Iodide, and water samples from Lake Bryan containing bacteria & viruses to assess their ice nucleation potential.
