HELENA, Mont. (AP) — Carroll College has received a four-year, $1 million grant to work with Montana State University and three tribal colleges to study the effects of environmental changes on the spread of infectious diseases.

The majority of the Howard Hughes Medical Institute grant will be used to support summer undergraduate research for six professors and up to 18 students at Carroll and the collaborating colleges, including Chief Dull Knife College, Little Big Horn College and Aaniiih (a-ah-nee) Nakoda College.

The award builds on Carroll's existing grant-funded research into West Nile virus. It also will include the study of other mosquito-borne diseases, such as blue tongue, heartworm and Cache Valley virus.

Carroll's grant is meant to help schools create more engaging science classes, bring real-world research experience to students and increase the diversity of students who study science.
