Expert is a specialist in the design of gas-fired furnaces for melting of metals. He received in 2017 a grant from the National Science Foundation for the design of a cokeless melting system for ferrous castings.

Expert is the author of an influential book on the engineering of slurry systems. He has close to 30 years of experience and has worked on a large number of mining as well as oil projects. He participated in the development of a slurry hydrocracking process for a major petroleum company and is listed as the inventor for the recovery of catalysts. He has also participated in projects in Canada for the extraction of tar sands, also called oil sands. He has engineering a number of slurry pipelines for construction of tailings dam as well as long distance concentrate transportation. He has a number of publications on smelting lances, lake de-silting and froth pumping. In the last two years expert has lead the effort to get an air permit for the first commercial cokeless foundry for iron melting in the United States.

Expert has also devoted a portion of his career to catalyst recovery through his work on slurry hydrocracking. He is the principal inventor of a patent A PROCESS FOR RECOVERING ULTRAFINE SOLIDS FROM A HYDROCARBON LIQUID. Preparation of packages for purchase of fixed and rotating equipment for refinery expansion and revamp to ASME and API codes. Corrosion engineering for various units of a refinery.

Splitvane Engineers Foundry Directed air permit application and construction for first commercial cokeless natural gas fired foundry for melting iron in the United States.

Expert has conducted research and published a paper on extracting gas hydrates from deep ocean and transporting in a slurry form.

A small foundry wanted to improve on the cokeless reverberatory cupola to melt iron with natural gas rather than coke but could not find an expert in the USA - since no commercial cokeless foundry was ever built. Expert was hired and led the process of design, obtaining the necessary air permit and order of construction from local authority for a 9000 tons per year plant.Advisor to Chevron for the development of a new process called "slurry hydrocracking" - Advised on appropriate levels of catalyst, and methods to recycle spent catalyst. Research lead to a patent.Lead engineer for the design of a tailings pipeline for Shell Canada/Albian Sands 150,000 barrels per day plant.Engineer for Fluor - participated over 5 years to the commissioning of copper concentrators, solvent extraction plants or design of slurry systems.A major gold producer had identified a site in the Andes at an altitude of 3900 m where gold was found in large quantity. However to access the ore body it was necessary to dredge a bog completely and transport water, gravel, silt and chopped up grass to a water storage pond at a higher altitude. The owner hired a geotechnical expert to conduct a feasibility study. The study initially focused on the top layers that consisted of grass, water and about 10% silt but then extrapolated to the bottom layers that contained sand and gravel up to 20 mm in diameter. The study had proposed to use 8 hydraulic excavators that were deemed very dangerous in the bog, and therefore required highly trained operators who could swim out of the bog. The 8 excavators were connected by hoses to a common pipeline to a sump on the shore feeding three pumps in series. The geotechnical consultant had assumed that the dredged material could be transported at the weight concentration of 40% while the submersible pumps typically dredged at the maximum weight concentration of 30%.

ORC provided peer review but indicated that the lower layers of the bog would require more pumping power as well as operation at higher velocity than the top layers due to a much coarser particle size distribution. ORC also expressed some concern that the hydraulic excavators had experienced in some other sites accidents tipping off and leading to accidental death of an operator. The peer review recommended using an air cushion platform that exerts a minimum pressure of 1 psi to navigate the bog. This also would have allowed the use two larger hydraulic driven submersibles to reduce the number of operators, hoses to the pipeline. An air cushion dredging platform was identified in Singapore for lease as well as another one in Vancouver, British Columbia. The peer review also recommended an increase of the number of booster pumps to four in series to handle the gravel at the deepest layers. The peer reviewer also identified the risk of formation of balls of clay with chopped grass that clog the pipeline in certain points and proposed a number of solutions such as proper design of booster pump station sump, discharge approach into the storage pond. The reviewer also recommended that the reclaim pumps in the storage pond be horizontal slurry pumps rather than vertical turbine pumps.

Outcome: The peer review resulted in a series of recommendations for a more stable dredging and pumping system while proposing a safer technology to avoid accidents associated with hydraulic excavators. The proposed single air cushion platform with large excavator and two large submersible pumps is also likely to reduce the number of operators and auxiliary refueling vehicles for the system proposed by the Geotechnical consultant.
Expert assisted a very large firm extracting oils and in Canada with very difficult disposal of mature fine tailings. Technology is currently subject to a patent application. Expert assisted a defendant in a 60 mile long phosphate pipeline to settle a difficult claim out of court.Prepared packages for a refinery's shut down replacing heat exchangers, pressure vessels and fired heaters.

Expert recently won a large monetary prize for his solutions for removing sediment from reservoirs. He and one other person won the top two positions for this competition. Reclamation launched this competition looking for new and improved techniques in order to remove sediment and transportation of that sediment in a cost-effective manner. Out of the 40 potential solutions entered, 6 were chosen for the cash prize, the 6 winners sharing $75,000 for their efforts. Being a significant problem for our countries reservoirs, sediments are an ever growing issue. The Bureau of Reclamation teamed up with the U.S. Army Corps of Engineers, Federal Energy Regulatory Commission, Natural Resource Conservation Service and American Rivers on various aspects for this competition.

Expert may consult nationally and internationally, and is also local to the following cities: Seattle, Washington - Bellevue, Washington - Everett, Washington - Federal Way, Washington - Kent, Washington - Bellingham, Washington - Renton, Washington
