I’m a biologist studying how selfish genetic elements, such as viruses, have infiltrated our genomes and influenced our evolution. I am currently a postdoctoral fellow in the labs of Dr. Cedric Feschotte and Dr. Nels Elde at the University of Utah in Salt Lake City.
March 2016: With all the bad press on viruses these days, it’s easy to forget that about 8% of our own DNA is viral in origin. These viral pieces of DNA are “fossils” of ancient retroviruses that infected our ancestors over the past 100 million years. Our study, just published in Science, reveals that some of these viral elements have been domesticated to help activate the innate immune response against modern-day viruses. As Sun Tzu stated in The Art of War, “The opportunity for defeating the enemy is provided by the enemy himself.” It seems host-virus evolutionary battles are no exception.
