Expert’s major contributions are in microbial control of wide range of medical devices and pharmaceuticals. He has a background in chemical engineering and polymer science. He has decades of experience from numerous companies- large device and pharmaceutical companies to startups developing medical devices and drug delivery systems. He has taken products from the laboratory to full commercial release. In developing these products there are regulatory needs, depending on the product, for low bioburden to full sterilization, 10^-6 sterility assurance levels (SAL). He has worked with a diverse range of materials from liquids, hydrogels, and plastics to structural metals and combinations thereof. He is an expert in the use of antimicrobials, determination of bioburden and all means of sterilization, including electron beam, gamma ray, ethylene oxide and thermal. With products developed, he has worked on long term stability at a range of temperatures. This includes selection of packaging materials and testing of the package with the product.

Expert’s [particular] expertise comes from background in materials science and extensive experience in all major sterilization processes. He therefore knows the changes in properties of a device, including package, due to sterilization and shelf life. A good example of this is Expert’s extensive experience in developing hydrogels from formulation to process and product. As use of hydrogel in a sterile product, it must overcome the issues of being a growth medium by choice of using antimicrobials. As hydrogels have high water content, the choice of the package is crucial. The interaction the sterilization process has upon the hydrogel has to be considered and operating conditions have to be established. The sterilization dose may not be high enough to achieve the required SAL but if too high may over cure or degrade the product. Another product area where he has made significant contributions is dialyzers. These devices are made of many different polymeric materials, therefore choosing effective materials including the membrane, that will be functional and not be damaged by sterilization is crucial.
