Dr. Deepika Dave’s Research Profile

Dr. Juran Goyali Postdoctoral Fellow

Dr. Juran Goyali
Postdoctoral Fellow

Dr. Juran Goyali joined the Marine Bioprocessing team at the Centre for Aquaculture and Seafood Development (CASD) as a Postdoctoral Fellow in February 2019. His current research interests focus on the development of processing technology to produce high-end quality products from seafood and its by-products. His research is emphasized to increase the yield, quality, shelf-life and competitiveness of sea cucumber products in the market.

Before joining CASD, Dr. Goyali worked with the plant physiology research group at Memorial University of Newfoundland (MUN) focused on the effect of abiotic (hypoxic) stresses on the metabolism and physiological development of plants. He completed his Ph.D. in Biology from MUN on the morphological, biochemical and molecular characterization of blueberry plants. His Ph.D. research was underlined on the evaluation of phytochemical content and antioxidant activity in blueberry leaves and fruits at different developmental stages, and identification of genetic and epigenetic variations in the blueberry plants propagated by advance and conventional propagation methods. He also worked as a Research Technician with Agriculture and Agri-Food Canada at the St. John’s Research and Development Centre.

Before moving to Canada, Dr. Goyali worked with a leading non-government organization, BRAC-Bangladesh, as a Seed Technologist where he managed and coordinated the project on producing and marketing seed potato. He acquired his Master’s degree in Plant Breeding from Punjab Agricultural University, Ludhiana, India, and Bachelor of Science in Agriculture from Bangladesh Agricultural University, Mymensingh.

Dr. Yi Liu Postdoctoral Fellow

Dr. Yi Liu
Postdoctoral Fellow

Dr. Yi Liu joined the Bioprocessing group as Postdoctoral Fellow in 2018. Her research is mainly focused on extraction and refining of fish oil and omega-3 fatty acids from salmon by-products. She is also involved in other marine-related projects such as determination of collagen from aquaculture and fishery waste resources and analysis of nutritional composition of sea cucumber by-products.

Dr. Liu holds a BSc degree in Chemistry Education from Jiangsu University, China, and a PhD degree in Green Chemistry from Memorial University. Her PhD research was focused on the synthesis of a novel compound from the monomer of chitin derived from shells of crustaceans, and related studies of its properties and applications. Her PhD thesis was titled “3-Acetamido-5-acetylfuran from N-acetyl-D-glucosamine: its synthesis, properties and applications”.

Prior to joining the Marine Institute, Dr. Liu worked as a science technician in Department of Chemistry, Memorial University, and a technical researcher in Integer Resources Inc.

Wade Murphy, Food Technologist, Marine Bioprocessing Facility Supervisor

Wade Murphy
Food Technologist, Marine Bioprocessing Facility Supervisor

Wade Murphy joined CASD in 1990 and has been part of the Bioprocessing unit since its inception. As Facility Supervisor he currently manages maintenance and expansion of the laboratory and pilot plant, and leads the procurement, modification and installation of processing equipment.
Throughout his career, Wade has gained expert knowledge of seafood processing technologies, operating seafood processing operations and work on processing efficiencies and familiarity with all aspects of the seafood processing industry and the companies operating the facilities. He holds a Diploma in Food Technology from the Marine Institute.
His growing interest in by-product utilization for the fin fish and shellfish industry initiated various applied research projects on composting, ensilaging, fish meal processing and the utilization of snow crab and shrimp shell which have ultimately laid the ground work for the establishment of the Marine Bioprocessing facility and its ability to perform research focused on marine by-products.
In his current position as Facility Supervisor, he plays an integral role in the development and implementation of project activity, especially the scale-up initiatives. He works with the marine bioprocessing research group to identify, procure and install processing equipment for processes being developed; performs pilot-scale production runs and ensures that the facility meets current Occupational Health and Safety guidelines.

Julia Pohling, Marine Biotechnologist

Julia Pohling
Marine Biotechnologist

Julia Pohling joined the CASD Bioprocessing team as Marine Biotechnologist in 2012. Her work focuses on industrial process optimization, pilot-scale process design, and research on waste management and by-product utilization.

Ms. Pohling holds a Bachelor and Master of Science degree in Biotechnology with a focus on bio-process engineering, in particular downstream processing, protein purification and bioreactor modeling. Her BSc thesis work was on the development of a cell-culture based Influenza split vaccine (Chiron Vaccines, Germany) while the MSc thesis was titled “Characterization of interferon expression patterns in Hepatitis B infection” (Health Sciences, Memorial University, St. John’s).
Following her graduation, Ms. Pohling continued worked in the field of basic immunological research (HIV) at before beginning to work for Abbott Diagnostics (Wiesbaden, Germany) in the position of Head Product Specialist in a team responsible for the manufacturing of diagnostic tests for Hepatitis.

Examples of her work at the Marine Institute are the development of an environmentally friendly chitin extraction process from shrimp shell, the extraction and evaluation of fish oil, characterization and treatment of plant effluent, extraction and analysis of marine pigments and other applied and analytical research projects into the development of marine by-products.
