Kevin Esvelt
Kevin M. Esvelt is an assistant professor of the MIT Media Lab, where he leads the Sculpting Evolution Group in exploring evolutionary and ecological engineering. The first to identify the potential for CRISPR “gene drive” systems capable of unilaterally altering wild populations of organisms, Esvelt and his colleagues defied scientific tradition by revealing their findings and calling for open discussion and safeguards before they demonstrated the technology in the laboratory. At MIT, the Sculpting Evolution Group develops local “daisy drives” for community-based environmental editing, which may be able to save endangered species and restore populations to their original genetics. Esvelt's work has appeared in major scientific journals, including Nature and Science, and features regularly in popular media, including The New York Times, The New Yorker, and NPR.

The Friday Five: Soon Band-Aids Could Be AIs

In this week's Friday Five, research on a "smart" bandage for wounds, a breakthrough in fighting inflammation, the pros and cons of a new drug for Alzheimer's, benefits of the Mediterranean diet with a twist, and we've learned to recycle a plastic that was un-recyclable.

Sexually Transmitted Infections are on the rise. This drug could stop them.

Cases of gonorrhea, chlamydia and syphilis soared last year, but researchers are finding that a drug known as doxy seems to reduce the number of infections.

Sexually transmitted infections (STIs) are surging across the U.S. to 2.5 million cases in 2021 according to preliminary data from the CDC. A new prevention and treatment strategy now in clinical trials may provide a way to get a handle on them.

It's easy to overlook the soaring rates of gonorrhea, chlamydia, and syphilis because most of those infections have few or no symptoms and can be identified only through testing. But left untreated, they can lead to serious damage to nerves and tissue, resulting in infertility, blindness, and dementia. Infants developing in utero are particularly vulnerable.

He is primarily interested in HIV, infectious disease, immunology, and how growing knowledge of the microbiome is changing our understanding of health and disease. He is working on a book about the ways the body can at least partially control HIV and how that has influenced (or not) the search for a treatment and cure.
