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.

Alicia Carter

Alicia Carter, B.S.


Alicia currently conducts algal toxin analysis using enzyme-linked immunosorbent assay (ELISA) and extracts/prepares samples for analysis with mass spectrometry. She also extracts and purifies materials for the CyanoLab division of GreenWater Laboratories. This includes utilizing preparative scale high performance liquid chromatography (HPLC) to purify algal toxins and assists in maintaining the algal culture room.

Alicia graduated from Jacksonville University where she received a B.S. in Biology. Alicia grew up in Jacksonville, FL and is a Marine Corps veteran.
