Carolyn Duckham studies the impact of climate change on the marine environment. Specifically, she's investigating the effects of ocean acidification on early larval stages of commercially valuable shellfish. Her project focuses on whether adding lime to sea water can chemically reverse ocean acidification, and therefore reverse its associated negative effects on the ability of larvae to produce shell material.

She says, "I decided that I needed a Master's degree to take me into a career in water resource and fisheries management. I also wanted to focus on climate change since it is a growing threat to the balance of aquatic ecosystems and their current management strategies."

She chose SFU’s graduate program in Resource and Environmental Management because it addresses both her career and research goals. She was particularly attracted to the fact that the program helps students with developing and executing a multi-disciplinary research project.

She is working with Dr. Karen Kohfeld, head of the Climate, Oceans, and Paleo-Environments (COPE) research group. The primary goal of her research is to find a cost-effective strategy to potentially reverse the ecological and economical damages associated with ocean acidification on the BC coast in the near future.

    Ph.D. Thesis DEFENSE HAIYANG WANG Master from Tongji University, CHINA 2005 Thursday May 30th, 2013 11:30 a.m. TASC1 9204 West FROM PEERS TO CLOUDS: DISTRIBUTED RESOURCES FOR CONTENT DELIVERY AND USER COLLABORATION In this thesis, we tackle the problem of content delivery and user collaboration with emerging Internet technologies. Our investigation starts from peer-to-peer (P2P) sharing with social relations to contemporary cloud computing with flexible resource provisioning. We seek to leverage distributed resources for efficient sharing and collaboration, which leads to a hybrid system design that seamlessly bridges users' local resources to public datacenters. We first explore social-network-based optimizations in peer-to-peer content delivery. We give solid evidences that long-term social relations can be found and applied to enhance the sharing efficiency in peer-to-peer networks, and present practical implementation strategies for the popular BitTorrent system. We then investigate the performance of cloud-based file synchronization applications and identify the bottlenecks in their system design, in particular, the task interferences. We propose an interference-aware provisioning algorithm, which effectively mitigates the problem. We further examine the users' interactions in state-of-the-art cloud-based distributed interactive applications. We find that, despite the benefit in terms of cost savings and better scalability, the cloud-based deployment greatly increases the users' interaction latency. We demonstrate that a smart assignment algorithms for virtual machines can remarkably reduce such latency. Finally, we present a real-world system design that effectively bridges users' local resources to enterprise cloud platforms. Our measurements as well as system analysis indicate that it serves as a complement of great potentials to enterprise cloud services.
