Martin Group, June 10, 2011 (left-to-right): Front: Karina Herrera, Yingjun Liu, Qi Chen, Mikinori Kuwata, Scot Martin, Julianna Braun, Soeren Zorn. Back: Carlos Mierzwa, Ronan Lebouteiller, Yue Zhang, Guangtao Zhang, Mackenzie Smith. History... "Professor Martin and his group are currently working on several problems of environmental chemistry and technology. They recently completed the Amazonian Aerosol Characterization Experiment (AMAZE-08), focusing on the connections among biological emissions in the Amazon Basin, the formation of particles from those emissions, and the ability of those particles to influence cloud formation (e.g., biological-climate connections and feedbacks mediated by chemistry). They are continuing work on the chemistry and processes of atmospheric particles using the Harvard Environmental Chamber." |
