Dr. Timlin has 20+ years’ experience in developing and applying advanced spectroscopy, microscopy, spectroscopic imaging, and analysis methods to understand complex relationships and dynamics in multi-component biological systems – systems relevant to both emerging infectious disease and bioenergy/biofuels and spanning multiple spatial scales.
Recent applications in bioenergy include localization of photosynthetic pigments and proteins with highly overlapped spectral properties in living individual cyanobacteria, algae and plant cells and discovery of spectroscopic markers for algal health and productivity in biofuels relevant strains. She has provided technical contribution and leadership for several projects to develop and deploy Sandia’s hyperspectral reflectance monitoring approach to assess algal biomass, growth state, and the detection of pond pests.
- Serves as POC coordinating research activities in the area of spectroradiometric monitoring
- Extension of spectroradiometric monitoring to the early warning detection of pond pests with subsequent 24/7 continuous assessment of cultures in SNL/CA’s Algae Raceway Testbed.
