Ph.D., University of South Florida, Marine Science, 1993

Research Interests:

Dr. Louda's research interests center around the so-called lipophilic pigments. Specifically, these are the chlorophylls, chlorophyll derivatives, carotenoids, certain polyaromatic hydrocarbons (perylene) and a dimeric indole-phenol (scytonemin).
