Molecular biologist Jason Buenrostro of Harvard University, environmental ecologist Lucy Hutrya of Boston University, and environmental engineer Linsey Marr of Virginia Tech are among the 20 people selected as 2023 MacArthur Fellows. The recipients of these so-called genius grants from the John D. and Catherine T. MacArthur Foundation will each receive $800,000 over 5 years “to pursue their own creative, intellectual, and professional inclinations” with “no strings attached,” according to the foundation’s website.
Buenrostro studies the mechanisms that regulate gene expression. He recently developed DNA sequencing methods that inform how cells function according to their location within tissues and helped find a way to zero in on genetic mutations in cancer cells. This information can help scientists understand how cancer cells evolve as they metastasize or become resistant to drugs.
Hutyra investigates how urbanization affects carbon cycle dynamics. Her work has shown that the surroundings of plant and soil ecosystems influence how they absorb carbon and suggests that urban forests are important for mitigating the effects of climate change.
“A lot of my work has focused on solutions and has tried to be tractable with what cities and individuals and communities could actually try to do to improve their livability,” Hutyra says.
Marr examines air quality and bioaerosols. Her work on the respiratory droplets that carry airborne pathogens, such as influenza and SARS-CoV-2—the virus that causes COVID-19—helped show how relative humidity changes these viruses’ stability. She was among the first to show how small aerosols transmit viruses in indoor air.
Marr says the fellowship money will help her pursue projects “that would have been hard to get funding for through traditional mechanisms because they’re too risky or too interdisciplinary or too applied.”
