Laboratory Summer Volunteer

The laboratory was fortunate this summer to have the assistance of recent South San Francisco High graduate Nancy Yip. Nancy was one of two high school interns who did a two month internship at the District the previous summer in 2016. She was willing to return this summer to help the laboratory staff with a variety of monitoring and surveillance programs. In particular, Nancy was especially helpful taking care of the District mosquito colony, recording and entering data, and doing DNA extraction for tick testing. She also participated in field activities.
