Killian Jr. Faculty Achievement Award winner for 2014–2015. Professor Chisholm holds a joint appointment in the Department of Biology and was recognized by the Killian Award committee for her discovery of Prochlorococcus, a microorganism with global impact. One faculty colleague observed, “Her work is a defining example of the value of thinking both big and small to make sense of the complex interplay of life and the environment.” Coverage of Professor Chisholm’s lecture is available at MIT News.
