I am ACOM’s chief GECKO-wrangler! I work with and contribute to GECKO-A, an internationally based tool for generating hyper-detailed atmospheric gas-phase mechanisms, aerosol production potential, and physical property distributions. I develop and maintain an ACOM-based user-friendly box model system that applies GECKO-A mechanisms to interpret a wide variety of field- and lab-based observations. My main interest is in working with colleagues - in ACOM and beyond – to define and construct model functionality to address the practical aspects of their science questions.
