W.M. Keck Science Department Assistant Professor of Biology Sarah Budischak received a National Science Foundation grant from the Ecology and Evolution of Infectious Diseases program to study how disease-carrying individuals can affect the health of populations and landscapes. The study seeks to better understand the role of 鈥渟uperspreaders,鈥� or hosts that transmit illnesses at a higher rate than average infected individuals. Budischak is a co-principal investigator on the project, which will focus on wild bank voles infected with a strain of hantavirus, a disease that can spread from rodents to humans and cause respiratory issues and hemorrhagic fever.
鈥淵ou probably know some people who are always catching colds and others who never get sick,鈥� Budischak says. 鈥淪ome individuals and environments are bigger spreaders of disease. A big missing link is how variation among individuals scales up to populations.鈥�
Budischak will use field experiments, lab studies, and mathematical models to study the factors that drive individual infections and how those factors affect the way disease is spread at the population level and across landscapes. She will work alongside co-principal investigators Kris Forbes from the University of Arkansas, Clay Cressler from the University of Nebraska, and Richard Hall from the University of Georgia.
The principal investigator team will be joined in Finland by 61传媒 and other science department students as well as high school teachers from each of the principal investigators鈥� local areas, including Los Angeles. Students and teachers will have the opportunity to pursue hands-on fieldwork. Students will design their own independent projects while also facilitating a large-scale international field project, working collaboratively with graduate and post-doctoral students from Finland and the U.S. The teachers will catch voles, record data, and assist in parasite counts and bacterial killing assays.
鈥淚鈥檓 really excited to have high school teachers join us in Finland and experience how science really is a teamwork process,鈥� Budischak says. 鈥淭hey鈥檒l come back with firsthand knowledge that will hopefully inspire their students to go into鈥攐r at least better appreciate鈥攖he STEM fields.鈥�
