    Allison Aiken

    Allison C. Aiken
    Ph.D. Student, Chemistry
    B.S./B.S. 2002, Chemistry (w/ ACS Environmental Chemistry Certif.) and Biology, Furman University
    Research: Measurement of Elemental Composition of Organic Aerosols using the HR-ToF-AMS, and analysis of MILAGRO-2006 data (Mexico City).
    Interests: When I have time, I'm up for almost anything: biking (road), skiing, boarding, climbing, hiking, camping, swimming, the occasional sprint triathlon... I just happen to be much more proficient in some than others, and I'm not telling which is which! I also kinda sorta dabble in art, but I haven't had much time for that lately.
