Expert has 32 years of industrial analytical chemistry experience. For the last 24 years of that period, he headed the analytical R&D organization of International Specialty Products, a $1.7B specialty chemical company (as of 2007). In his time heading that laboratory, his staff produced approximately 1500 new, validated methods relating to company products. Expert has a strong reputation for the quality of the results reported by his staff.

Expert supervised an industrial analytical research laboratory which possessed and successfully effectively deployed a wide variety of analytical technologies including chromatography (GC, GC/MS, HPLC, LC/MS, pyrolysis GC, ion chromatography, CE); spectroscopy (NMR, FT-IR, near-IR, UV-visible, ICP-OES); microscopy (optical, SEM, AFM); polymer characterization (GPC, viscometry, rheology, thermal analysis, physical testing, osmometry, light scattering photometry); and classical methods (titrations, gravimetry, colorimetry, pycnometry). Samples included polymers, surfactants, preservatives, sunscreens, emollients, various low molecular weight organics as well as complex mixtures and formulations.

In 1991, Expert established a process analytical cross-functional team at ISP to improve the consistency of key chemical processes, improve yield, reduce waste and pollution, and reduce in-process laboratory testing (and associated costs). A wide variety of successful projects were completed from 1991 to 2007 involving such technologies as near-IR spectroscopy (for vinylation reactions, polymerization reactions, and moisture in product dryers), viscometry, density meters, and gas chromatography. This effort long predated the PAT initiative enunciated by the FDA in 2004 as well as QbD (quality by design) and allowed ISP to maintain its position as a premier supplier of pharmaceutical excipients.

As chief quality officer for ISP from 2001 to 2006, Expert was responsible for ensuring the adherence to cGMP requirements for both pharmaceutical and cosmetic products. He was responsible for eliminating a major quality problem in an aqueous hair care polymer line, namely microbial contamination, through a radical overhaul of the incoming process water system. In addition, he led the cGMP qualification of new Asian suppliers of key sunscreen products to be resold by ISP into the U.S. and Canada (where sunscreens are considered to be drugs).

Expert's early career as a bench analytical chemist emphasized the analysis of polymeric materials. He is a recognized authority in the area of molecular weight measurement with respect to gel permeation chromatography (also known as size exclusion chromatography). He has a number of peer reviewed publications in this field including two chapters in the Marcel Dekker "Handbook of Size Exclusion Chromatography". Expert has also heavily used colligative property measurements (membrane and vapor phase osmometry) in his work as well as light scattering photometry and thermal analysis (differential scanning calorimetry and thermogravimetric analysis).

As chief quality officer for ISP from 2001 to 2006, Expert was responsible for ensuring the adherence to cGMP requirements for both pharmaceutical and cosmetic products. The standards for manufacturing pharmaceutical excipients at ISP were set to coincide with those at the highest level, namely active pharmaceutical ingredients, APIs, under 21 CFR part 211 and ICH Q7. In his consulting practice, Expert has continued to utilize his knowledge of API cGMP requirements to provide audit services for pharmaceutical firms wishing to monitor the degree of compliance of their suppliers or to qualify new suppliers. In 2007, he earned the American Society for Quality's Certified Quality Auditor credential.

Expert performed an assessment of laboratory and on-line analytical opportunities for increased efficiency and cost savings at a major inorganic chemicals manufacturing site. He uncovered a major opportunity to increase yield and reduce cost at the plant through the use of an on-line Raman spectroscopy monitoring/control system. Additionally, he provided insight to improve, consolidate and streamline QC laboratory operations through the elimination of (manually intensive) antiquated / unreliable tests with modern multitasking instruments. He has performed several supplier cGMP compliance audits for a virtual pharmaceutical company client. In so doing, he uncovered a number of major deficiencies the client was not aware of in the suppliers' operations. The resulting corrective actions prevented an adverse reaction from the FDA which could have potentially interfered with the client's business plan.
