Jesse Kroll, assistant professor of civil and environmental engineering and chemical engineering, received the Kenneth T. Whitby Award from the American Association for Aerosol Research during the organization’s annual meeting Oct. 10, in Minneapolis. Nominators said of Kroll’s work: “His recent paper in Nature Chemistry (2011) entitled ‘Carbon oxidation state as a metric for describing the chemistry of atmospheric organic aerosol’ will soon be considered a classic … his work has introduced new paradigms.” “His experience in atmospheric chemistry is broad and diverse, ranging from very fundamental laboratory studies of oxidation chemistry to field measurements of aerosol composition.” “He will be a leader among the young generation of aerosol scientists and atmospheric chemists.”
