GWL/CL is nationally and internationally recognized as leaders in the field of toxigenic cyanobacteria analyses. Our staff has over 50 years cumulative experience in the fields of aquatic biology, limnology, phycology, toxicology, analytical chemistry and cyanotoxin analyses.
Mark Aubel, Ph.D.
Mark is the lead analytical chemist at GreenWater Laboratories/CyanoLab and has been a member of the staff since 2002. Mark's main responsibilities are to: 1) perform liquid chromatography/mass spectrometry analysis on samples, 2) supervise new protocol development and 3) monitor quality assurance and control.
Mark has co-authored multiple papers on cyanobacerial toxin analysis and was requested by the USEPA to participate and provide commentary on analytical techniques necessary for the accurate identification and quantification of algal toxins in drinking water.
Andrew Chapman, M.S.
Andy is the senior phycologist at GreenWater Laboratories/CyanoLab and has been with GWL/CL since its establishment in 2001. Andy is a nationally recognized phycologist who specializes in, but is not limited to, the identification and enumeration of cyanobacteria, specifically potentially toxin producing genera/species.
Andy has developed, organized, assisted and administered workshops on the identification and classification of freshwater algae to such organizations as the Florida Lake Management Society, the North American Lake Management Society, the Florida Fish and Wildlife Conservation Commission and Florida Drinking Water Treatment Plants.
Although a freshwater algal specialist by training, Andy can also perform algal identification on estuarine and marine species as well. Andy has performed analyses for the USGS, the USEPA, the St. Johns River Water Management District, the Florida Fish and Wildlife Conservation Commission and the Center for Disease Control, to name but a few.
Amanda Foss, M.S.
Amanda is a chemist at GreenWater Laboratories with a focus on analytical extraction and analysis techniques. Amanda is currently enrolled in the Forensic Toxicology Program at the University of Florida College of Veterinary Medicine. Amanda received a B.S. in Environmental Chemistry at Lake Superior State University and an M.S. in Fisheries and Aquatic Sciences at the University of Florida.
At GreenWater Laboratories/CyanoLab, Amanda performs algal toxin analysis using Enzyme-Linked Immunosorbent Assay (ELISA) and High Performance Liquid Chromatography (HPLC) coupled with fluorescence, PDA, and mass spectrometry. Amanda directs research involving the development and validation of methods for the extraction and quantification algal toxins from difficult biological matrices. Amanda also assists with algal identification, maintains the algal culture room, and extracts/purifies toxin standards.
Nara Souza, M.S.
Nara is a Biologist at GreenWater Laboratories with expertise in algal identification/enumeration and a focus on cyanobacteria. Nara brings a unique skill set beneficial to GWL/CL clients. She received a bachelor's degree in Biological Science at Potiguar University in Brazil and an M.S. in aquatic bioecology at Federal University of Rio Grande do Norte, Brazil. Her past experience includes four years of work with the Florida Fish and Wildlife Conservation Commission and she also has some training in the field of law enforcement/crime scene analysis. At GWL/CL, Nara maintains the algal culturing room and assists with the algal toxin standard program. She is being trained to conduct cyanotoxin analysis utilizing ELISA and will provide assistance with toxin extractions and HPLC analyses. Being from Brazil, Nara is fluent in Portuguese, enjoys the outdoors and silversmithing.
As a recent graduate, Alicia supports all laboratory directed efforts and is learning new skills in the fields of chemistry and biology. Alicia currently assists in algal toxin analysis by preparing samples for enzyme-linked immunosorbent assay (ELISA) and mass spectrometry. She also utilizes preparative scale high performance liquid chromatography (HPLC) to purify algal toxins and assists in maintaining the algal culture room. In addition, Alicia is currently implementing chlorophyll a analysis in order to expand the services offered by GWL/CL.
Alicia recently graduated from Jacksonville University where she received a B.S. in Biology. Alicia grew up in Jacksonville, FL and is a Marine Corps veteran.
