Our Team

Dr. Ahmed Siah, PhD

Managing Director

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.

Ahmed and his wife live in Campbell River with their young family. He’s an avid soccer player.

Dr. Wyth Marshall, BSc, Cert. Enviro Restor, PhD

Research Scientist

Wyth joined the team at BC CAHS in 2010 as a Postdoctoral research fellow. She completed her PhD at the department of Botany at the University of British Columbia the previous year. She also holds a BSc in Biology and a certificate in Environmental Restoration from the University of Victoria. Her main research interest is in microbial ecology, specifically of parasites and aquatic disease organisms. Wyth’s PhD work involved the discovery and characterization of new genera and species of symbiotic protozoa (Ichthyosporea and Thraustochytridae), using phylogenetics, population genetics, light and electron microscopy. Previously she worked and volunteered with the shellfish parasitology group at the Pacific Biological Station (DFO). She also curates a tree of life page. http://tolweb.org/Ichthyosporea/121172

Currently she leads research aimed at understanding the ecology and life-history of Kudoa thyrsites, a myxozoan parasite of farmed Atlantic salmon. Funding for her position comes from an Industrial Research and Development Fellowship from the Natural Sciences and Engineering Research Council of Canada (NSERC).

When not at BC CAHS, Wyth loves windsurfing, gardening, and mushroom picking.

Danielle New, Dip Enviro Tech, BSc
