William Cheung – Associated Faculty

williamDr. William Cheung is a Professor at the Institute for the Oceans and Fisheries, UBC and the Director (Science) of the Nippon Foundation-UBC Nereus Program. His main research areas include understanding the responses and vulnerabilities of marine ecosystems and fisheries to global change, and examining trade-offs in managing and conserving living marine resources. His works cut across multiple disciplines, from oceanography to ecology, economics and social sciences, and range from local to global scales.

William has published over 150 peer-reviewed publications [Google Scholar], including papers in leading international journals. William is also actively involved in international and regional initiatives that bridge science and policy. For instance, he was a Lead Author in the Working Group II of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), a Coordinating Lead Author of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) and Global Biodiversity Outlook. He serves as member of the editorial board of Fish and Fisheries, Fisheries Oceanography and Frontiers in Marine Sciences, and as scientific advisors in a number of international and local organizations including BioDiscovery, IUCN and WWF Canada.

William obtained his BSc in Biology and M.Phil. from the University of Hong Kong. He worked for WWF Hong Kong for two years, after which he completed his Ph.D. in Resource Management and Environmental Studies at UBC. From 2009 to 2011, he was Lecturer in Marine Ecosystem Services in the School of Environmental Sciences, University of East Anglia.

First Global Estimate of Fish Biomass

fishrocksSea Around Us Project member Villy Christensen is author on a paper that provides first-ever estimate of worldwide fish biomass and impact on climate change. Read the press release and the full study published in Science (here also is a link to the associated ‘perspective’ article). Below is a video animation of fish excreting pellets of calcium carbonate, a chalk-like substance also known as “gut rocks,” in a process completely separate from food digestion (animation by Dalai Felinto).

Ar’ash Tavakolie – Senior Web Developer

arash_bioAr’ash is a senior software developer, and comes from an engineering/Artificial Intelligence background. He has been designing and developing .NET based solutions for about eight years.

Ar’ash designs and maintains the Sea Around Us suite of web applications and the related databases. He is currently busy working on ‘SwordFish (SF)’, which will replace the core components of legacy code with a multi-tiered architecture [DataWarehouse + AnalysisEngine + ClientModules]. He is developing SF to make the web/databases applications more agile, extensible and also lower the maintenance costs. SwordFish is based on OLAP/BI, C#, and .NET technologies. SF prototypes showed that MDX querying language is closer to the domain and can reduce the lines of codes by 80%.

Ar’ash is also an avid tea fan and likes reading books. Currently his favorite novelist is Haruki Murakami and his favorite programming gargoyle/guru/writer is Martin Fowler “Any fool can write code that a computer can understand. Good programmers write code that humans can understand.” Ar’ash regularly and enthusiastically baffles project staff during meetings by trumping the biologists’ ability to talk in technical jargon.
