Dr. Aaruun Arunachalam
As instructor mathematics and physics at the college’s Burin Campus, Dr. Aaruun Arunachalam is researching computational models to better predict the effects of forces on engineered structures, particularly as it relates to ice and its effects on structures located at sea. The research will enable offshore operators to build structures better designed to withstand ice-induced forces, making offshore activities safer and more predictable. Understanding the limits of an engineering design in withstanding the forces of sheet ice and other ice-induced forces is the first step in the design of any engineering process. Depending on the intensity, type, and distribution of forces, and the characteristics of the engineered structures, the behavior of the structures will be different. The ability to estimate the intensity, type, nature and distribution of these forces on structures like ships and offshore oil platforms will greatly improve safety and predictive risk management. Available experimental data is being used to apply the concept of dimensional analysis and similarity theory to developing the most realistic computational models for ice-induced forces on structures interacting with sheet ice. Dr. Arunachalam’s research on computational models and designs for ice-induced forces on offshore structures will pave the way for further improvements in understanding the physics of the ice-structure interaction problem.
A biophysicist, agricultural meteorologist, and Certified Engineering Technologist, Dr. Graham brings this team approach to his research interests and his additional role as a researcher and educator in biology and engineering technology. Dr. Graham is the key driver behind a project to investigate wave powered pumping of seawater: the Wave-Powered Pumping of Seawater for On-Shore Use and Electrical Generation Project in Lord’s Cove, near the campus on the Burin Peninsula. The interdisciplinary research project is prototype development and testing of a wave-powered pump that will use water flow to supply a flushing stream for shore-based operations. Many onshore or platform-based activities, such as aquaculture and fish processing, use high flows of seawater driven by electrical pumps at considerable cost. Dr. Graham is researching how best to harness the power of wave action to bring seawater to shore for these operations. Set up of an onshore aquaculture farm optimizing feed and waste in the water flow for a number of species is another key aspect of the project. Minor modifications to this design can allow the pump to generate electricity from wave action. Power can also be made from the flow of returning water to the ocean. The collaborative approach of this project has allowed the incorporation of skills and contributions from various stakeholders, both from within the college and externally, and continues to form the basis of Dr. Graham’s continued research into the possibilities of wave-powered energy.

Dr. Gary Thompson
A registered professional geoscientist, Dr. Thompson’s research activities are of particular interest for mining and natural resources exploration, shaping discovery and extraction strategies for operators. Dr. Thompson is the NSERC Industrial Research Chair for Colleges in Applied Mineralogy. His research activities focus on new process development and technology innovations in applied mineralogy, specifically dealing with the issues and challenges encountered by Vale NL in its current mining endeavors. The innovative approach in the Chair's research is to link the geology and characterization of the deposits directly with ore recovery processes. Dr. Thompson’s research focuses on geochemical techniques used in research for mineral exploration.
In 2009, Dr. Thompson was awarded an Industrial Research and Innovation Fund grant to explore methods for the discovery and extraction of ore below bedrock. Most, if not all, exposed ore has already been discovered in Newfoundland and Labrador. Any remaining economic deposits are hidden below the surface of exposed bedrock, making geophysical and geochemical methods for mineral exploration increasingly important. Dr. Thompson’s more recent research has focused on trace element mineral chemistry and application methods for finding buried uranium deposits and orthomagmatic nickel sulfide deposits. Over the summer of 2009, with support of Aurora Energy Inc. and Memorial University, a study was initiated to examine biogeochemical exploration techniques in the Central Mineral Belt, Labrador.
In 14 years of designing and administering GIS (Geographic Information Systems) and the ESRI Platforms, Rick Wheeler has witnessed the evolution of geospatial research methods. As GPS (Global Positioning System) navigation and GIS data models have evolved, so too have the information systems which manage and analyze the resulting data. As a Data and Systems Specialist at the college’s Geospatial Research Facility (GRF), located at its Corner Brook Campus, Wheeler is trained in a wide variety of server-based technologies for geospatial applications. He is responsible for geo-database design implementation and management, and works with industry and government partners on the design, configuration, training and testing of field-based data collectors, GPS systems and GIS server management. A frequent collaborator with public and private forestry stakeholders, Wheeler is often involved in the design and implementation of information systems for various projects.

Ken Wheeler, P.Eng.
When raw materials are extracted from the earth, processes are employed to extract the valuable components and convert them into products that can be sold to a market. Inevitably, various forms of 'waste' are produced during this process - high variability, lost time, excess material usage, high energy consumption, low recoveries, etc. These wastes may have significant impacts on an organization’s bottom line as well as on the environment.
As a practicing professional engineer and instructor in the Process Operations Engineering Technology (POET) program, Ken emphasizes the need to be persistent in the search for opportunities to eliminate process wastes wherever they occur and to continuously improve the process. The end result will be a more stable and efficient process, with lower environmental impacts and liabilities.
Ken’s current research interests include:
- Identification of process control problems using a combination of historical data and process knowledge, and recommending opportunities for process improvement.
- Investigation of opportunities to reprocess mine tailings with a view to reducing acid mine drainage issues and generating revenue from the sale of valuable minerals or new products.
