'''Ronald R. Breaker''' (born 1964) is an American biochemist who has been a Sterling Professor of Molecular, Cellular, and Developmental Biology at Yale University since 1995. He is best known for the discovery of riboswitches, a common RNA regulatory element. His current research is focused on understanding advanced functions of nucleic acids, including the discovery and analysis of riboswitches and ribozymes.<ref name="C&EN Article">{{cite news |last1=Yarnell |first1=Amanda |title=C&EN: Aha!

==Research== Ronald earned his B.S. in biology and chemistry from the University of Wisconsin&ndash;Stevens Point and his Ph.D. in biochemistry from Purdue University with Peter T Gilham. He was a postdoctoral fellow at The Scripps Research Institute with Gerald Joyce. While at Scripps, he isolated the first DNA enzyme (deoxyribozyme).<ref>{{cite journal |last1=Breaker |first1=RR |last2=Joyce |first2=GF |title=A DNA enzyme that cleaves RNA. |journal=Chemistry & Biology |date=December 1994 |volume=1 |issue=4 |pages=223–9 |doi=10.1016/1074-5521(94)90014-0 |pmid=9383394}}</ref> He joined the molecular, cellular, and developmental biology department at Yale University.
