Expert was responsible for building a new manufacturing facility for hollow-fiber thin film composite membranes for industrial gas and liquid. He helped design the equipment, created the plant layout, hired staff, and led the trouble-shooting phase. He led the engineering design of several membrane products and helped write technical marketing collateral.

Through 14 years of practical membrane experience, Expert has a broad knowledge of membrane materials. He has worked with membranes for medical devices, dialysis, industrial gas and liquid separations, and chemical process plant unit operations. He started a hollow-fiber membrane manufacturing plant using thin film composite polyethersulfone. He has worked with many membrane materials including polysulfones, polyimides, polyamides, cellulosics, PAN, and PTFE.

Expert has worked in separation science for over 20 years. His primary experience is with membranes and filters. However, he has worked in significant depth in many other separation technologies including absorption, adsorption, distillation, liquid-liquid extraction, and liquid chromatography. He offers excellent insight into the applicability of membranes to a particular separation. He has experience with making membranes as well as designing devices that use membranes. He can speak on a practical or theoretical level as is appropriate for a situation.

Expert has set up a laboratory for validating polymeric materials for pharmaceutical uses--both in processing (filters) and end use (containers and closures). In particular, he is expert in determining what extractables and leachables come off out of polymers in actual applications. This involves FDA autidable protocols that allow for the identification and quantification of extractables from solutions that would normally be considered too difficult to analyze. The finished product is a report that can be taken to the FDA.

Expert has a broad and deep background in membranes and filters, including materials, manufacturing methods, and use in specific applications. He has experience with both industrial and medical applications. He is a natural teacher and lecturer and has been asked to give general membrane primers to companies who need to learn more about membranes and filters.

Expert spent seven years developing microporous membranes for industrial gas and liquid separations. He understands solvent-based processes where poreformers are used to create the pore structure. He does not have experience with the hot melt spinning process technique.

Expert spent seven years developing a thin film composite hollow-fiber membrane for industrial gas and liquid separations. He helped develop models to simulate gas separation using counter-current and cross-flow model configurations. He has tested membrane separations including water vapor from air, organics from air, polar organics from non-polar organics, and oxygen from nitrogen.
He has also been involved with gas separation with other technologies, including absorption and adsorption (activated carbon, zeolites) and can discuss the advantages of each for a specific application.

Expert has worked with filters for medical and pharmaceutical use for several years. He has helped customers modify existing filters for a specific application (hydrophobic/hydrophilic self-venting filter). He has worked with many different filter materials and understands their strengths and weaknesses. He is familiar with the requirements of FDA registration and can consult regarding validation.

Expert has broad experience with microfiltration and ultrafiltration in industrial and medical application. He has developed ultrafilters for wastewater clean up. He has performed comparative testing for protein concentration using cross flow (also called tangential flow) cassettes. He has performed chemical treatments to membrane filters for specific affinities.

Expert's filtration background is strongest for pharmaceutical processing and medical devices. He is intimately familiar with filtration products from the major filter suppliers including Pall, Millipore, Whatman and Sartorius. He has performed filtration and cross-flow filtration studies for customers. He can also produce FDA auditable data under GLP conditions.

Expert has worked with major pharmaceutical filter manufacturers to optimize their filters for specific applications. He can perform filterability tests and adsorption studies, and can consult regarding integrity tests and other validation tests.



Expert developed a hydrophobic chemical treatment for a medical syringe filter.He determined a polymer manufacturing process and was the inventor for a competitive gas separation membrane.He performed a market study for a membrane-based medical device. The study included current technology, evaluation of competitors, future trends, and unmet opportunities.He determined if nanofiltration membranes can be used for a medical application.He performed tests to compare tangential-flow filtration cassettes for protein concentration.

Expert may consult nationally and internationally, and is also local to the following cities: Portland, Oregon - Eugene, Oregon - Salem, Oregon - Springfield, Oregon - Bend, Oregon
