Amanda Foss

Amanda Foss, M.S.


Amanda is a chemist with a focus on analytical extraction and analysis techniques. She received a B.S. in Environmental Chemistry and M.S. degrees in Forensic Toxicology and Fisheries/Aquatic Sciences from the University of Florida. Amanda has over a decade of experience with cyanotoxin analysis.

Amanda performs algal toxin analyses and directs research involving the development and validation of methods for the extraction and quantification of algal toxins from biological matrices (e.g. tissues, serum). Amanda also assists with algal identification and extracts/purifies toxin standards.

Kamil Cieslik

Kamil Cieslik


Kamil is finalizing a B.S. degree in Chemistry this fall at University of Central Florida. His current project at UCF is focused on the fabrication of water soluble organic photovoltaics. The goal of this research is to improve upon current fabrication efforts in the field of solar power. At GreenWater Laboratories Kamil currently conducts algal toxin analysis using enzyme-linked immunosorbent assay (ELISA) and extracts/prepares samples for analysis with mass spectrometry. With a strong background in Chemistry, Kamil is an excellent addition to the GreenWater team and will be expanding his expertise to HPLC and mass spectrometry techniques, as well as phyocology.
