Dr. Ahmed Siah, PhD

Research Scientist/Microbiology Diagnostician

Ahmed joined the team at BC CAHS in November 2011. His duties include managing research projects, developing new technologies in the field of aquatic health diagnostics and implementing and validating molecular biology technologies for diagnostics. Dr. Siah pursued his Postdoctoral studies in Molecular Ecotoxicology at the University of Le Havre in France after earning his PhD in Oceanography at the Institute of Marine Sciences in Rimouski, Quebec. As a Research Associate at Prince Edward Island’s Atlantic Veterinary College, he led and managed several projects on mollusk health management and the development of molecular diagnostic tools. Ahmed’s research focused primarily on identifying molecular biomarkers related to shellfish diseases and on developing new technologies to detect micro-organisms affecting fish and shellfish health. While at the Atlantic Veterinary College, Ahmed worked on hemic neoplasia in soft shell clams and developed diagnostic assays for rapid and high-throughput detection of tunicate invasive species which are heavily affecting the mussel industry in PEI.
