Kolb is an associate engineer at the RAND Corporation and holds a Ph.D. in civil and environmental engineering from Carnegie Mellon University. Since joining RAND, she has worked primarily in the Homeland Security Operational Analysis Center (HSOAC), with a particular focus on FEMA disaster recovery work. She has helped develop statistical sampling algorithms for TSA and conducted risk assessments for the U.S. Coast Guard. Her dissertation work focused on modeling the effects of source water bromide on drinking water disinfection by-product (DBP) formation and health risk. She also assessed the efficacy of the regulatory framework for DBPs when bromide is elevated. During her Ph.D., Kolb also received a Fulbright Fellowship where she worked with the Costa Rican Ministry of the Environment and the National University of Costa Rica to model the effects of saltwater intrusion in a coastal aquifer system.
