Some things I do
Research Scientist, Colorado State University
Interested in aerosol-water-cloud-climate interactions, particularly (biogenic secondary) organic aerosols
Recent study
measurements of water uptake 90-99%; improved theoretical descriptions of BSOA water uptake
moving to colder temperatures: homogeneous freezing (ice) of haze (< -40C) and heterogeneous ice nucleation; identify potential role of SOA in ice initiation

2. Hygroscopic growth factor CCN activity Ice nucleation (> -40 C)
