Jerilyn Timlin serves as a principal investigator for the Algal Predator and Pathogen Signature Verification project. The project looks at exploring and exploiting the various detailed optical signatures that arise when the algae cultivation pond surface is monitored using Sandia’s optical spectroradiometric techniques. These techniques can differentiate algae growth and state of health and provide an early warning of the active presence of predators and pathogens in outdoor algal ponds. In 2009, Jerilyn was presented by the National Institutes of Health (NIH) with a New Innovator Award to develop state-of-the-art imaging technology that can measure protein complex formation and protein networks.
