Richard Marc Losick (/ˈlsɪk/ LOH-sik;[1] born 1943) is an American molecular biologist. He is the Maria Moors Cabot Professor of Biology at Harvard University[2] and a professor at the Howard Hughes Medical Institute.[3] He is especially noted for his investigations of endospore formation in Gram positive organisms such as Bacillus subtilis.

Education and career edit

Losick received his AB in Chemistry from Princeton University in 1965, and his PhD in biochemistry from Massachusetts Institute of Technology in 1969.[4] Following his graduate studies, Losick was named a Junior Fellow of the Harvard Society of Fellows. He joined the Harvard faculty in 1972.[5] He has held the position of chairman in the Departments of Cellular and Developmental Biology and Molecular and Cellular Biology.[6] Along with Daniel Kahne, Robert Lue, and Susan Mango, he teaches Life Sciences 1a, an introductory biology and chemistry course, which was the fourth largest lecture course taught at Harvard College in 2015.[7]

Research edit

Losick's research interests include RNA polymerase, sigma factors, regulation of gene transcription, and bacterial development. He is known for his studies of asymmetric division in Bacillus subtilis, which divides to form one endospore and one nurturing cell.[6] Currently, Losick studies biofilm formation by the opportunistic pathogen Staphylococcus aureus. His research group has demonstrated that chromosomal DNA is recycled to form an electrostatic extracellular net in order to hold neighboring bacterial cells together.[8]
