Biography

Elsa Cordova has over 20 years of experience working on multiple projects in a chemistry environment. Elsa performs work on a broad range of research topics including glass dissolution chemistry, batch sorption/sorption loading and kinetics, biological geochemistry, and soil characterization in support of multiple projects. Other non-project activities include space management, activity lead, and new staff mentoring.

Elsa also interacts directly with students all year long. She loves working with young people and takes pleasure in providing guidance and hands-on learning in a lab setting.
