JULY 31, 2014 Erik Sontheimer, PhD, joins RTI Dr. Erik Sontheimer has joined us from Northwestern University. The Sontheimer laboratory focuses on the roles of RNA molecules in gene expression, with an emphasis on genetic interference pathways. Using biochemical approaches to characterize the function of the RNAi machinery, Dr. Sontheimer's research has yielded fundamental insights into the biochemical mechanism of RNAi and the pathway by which the RNAi machinery assembles on a double-stranded RNA. His research has recently expanded into a distinct interference pathway specified by CRISPR loci that limits the spread of antibiotic resistance in pathogenic bacteria.

Though retroviruses like HIV are best known as the cause of diseases such as AIDS, a huge portion of the human genome consists of fossil remnants of retrovirus infection from millions of years ago.
