Expert is a microbiologist with expertise in microbiology and biotechnology with 7 years of consulting experience advising large and small industrial clients as well as venture capitalists and investment groups on emerging technologies in areas such as biocides, biofouling, biofilms, harmful algal blooms, microbial monitoring, renewable chemical production, and sustainable manufacturing. Clients are generally concerned with viability of new technologies, intellectual property, and milestones for start- up companies. He has 11 years of industrial experience as a senior research scientist with Hercules Pulp and Paper Group (now Solenis) developing less toxic microbial control and rapid monitoring methods to improve economics and environmental friendliness of paper production. Examples of research activities included tracking and eradication of spore forming bacteria, and control fungal contamination in construction material. An area of emphasis was the application of enzymes as alternatives to traditional chemical application. Xylanases and laccases have potential in pulp bleaching as well as renewable chemical production. Cellulases have applications in pulp and paper production, hydraulic fracturing, and chemicals from cellulosic feedstocks. Prior to his industrial work he worked extensively in characterization of microbial communities degrading organic contaminants. An area of emphasis was exploitation gene probe and DNA fingerprint technology to help optimize activity of key catalytic microbial populations in various matrices. Nucleic acid based technologies allow for diagnosis of community composition which has direct impact on bioreactor performance, product production, pathogen presence, and metabolic potential, in a more rapid and inclusive way than many traditional analysis.

The areas of expertise associated with this summary support the above areas. Genetic and DNA probe technology support monitoring of microbial systems whether for contamination, chemical production, or bioremediation. Fermentation technology is being bolstered by genetic engineering through mechanisms such as directed evolution coupled with high through put screeining. These methods promote the development of unique biological catalysts and are corner stones of start up biotech companies as well as established companies such as Novozymes, DSM, and DuPont. Expert has worked as a research scientist bring new technologies such as biological bleach to the paper industry. These sorts of advances have the potential to improve both profitability and sustainability in a number of industries.

Expert may consult nationally and internationally, and is also local to the following cities: Jacksonville, Florida - Savannah, Georgia - Charleston, South Carolina

Work History

Years Employer Title Department Responsibilities
Years: 2007 to Present Employer: Undisclosed Title: Principal Department: Undisclosed Responsibilities: Work with clients to identify differentiating products, processes and technologies in various industries and specific companies. Anticipate industry trends in areas such as antimicrobial development, contamination control, bioremediation, biofuels, renewable chemicals and sustainable production. Elucidate strengths of various companies involved in biotechnology specifically with an industrial rather than medical focus. Survey patent and scientific literature. Assess economic viability of new companies and technologies relative to current practices or competitive threats
Years: 2008 to 2013 Employer: A respected American University Title: Adjunct Professor Department: Biology Responsibilities: Teaching lecture and Laboratory section of Microbiology.
Years: 1995 to 2006 Employer: Hercules Title: Undisclosed Department: Pulp and Paper Responsibilities: Augmentation of chloramine chemistry for microbial control in paper mill whitewater. Development of non-toxic enhancers to promote the efficacy of traditional biocides. Products were developed for cost effectiveness, differentiation and required to meet EPA and FDA specifications for the pulp and paper industry. Development of novel technology for on-line monitoring of biofouling in the pulp and paper industry. Monitoring of biofouling promotes both cost effective and rational dosing of antimicrobial compounds and provides an advantage over competitors. Monitoring and optimization of a biological process to remove halogenated contaminants from a "wet strength" additive. Resulted in extended production runs and estimated cost savings of 25- 30%. Evaluation of non-chemical methods for the treatment of industrial process water for microbiological control. Applications were not effective for "open" systems (such as most paper mills) but had potential for cost reduction and reduced environmental and safety concerns for "closed" systems such as cooling towers. Development of haloamine chemistries for the control of bacterial populations in the pulp and paper industry. Work lead to the reduced cost (in excess of 50%) of raw materials and decreased used of halogens. Co-investigator for novel mold proofing biocides for the pulp and paper industry. Work lead to expansion of product line to aligned industries such as construction materials. Processes to optimize the production of laccase for biological bleaching of pulp. Involved both batch and continuous culture production of enzymes from both bacteria and yeast. PCR based system for the rapid, on-site, detection of spore forming bacteria in the pulp and paper industry ( project resulted in Hercules 1999 Research Award and field trials and presentation at Stora Enso Research Center Imatra, Finland and International Paper Pine Bluff, Arkansas). Application of PCR based and gene probe diagnostics to the bacterial populations colonizing paper mills. DNA fingerprinting technologies had not been used in the pulp and paper industry prior to this work. Developed use of non-toxic germinants to control spore forming bacteria in the production of food grade paper board. Field trial and presentation to paper mill staff at Millnthorpe, UK. Process control, monitoring, and optimization of a biological process for the removal of chlorinated contaminants from a Hercules product. Turn around time for analysis of microbial populations was reduced from 4 days to less than 8 hours. This allowed operators to assess efficiency of the process and take appropriate action
Years: 1992 to 1995 Employer: University of Cincinnati/ US EPA Title: Undisclosed Department: Dept. Molecular Genetics/ Risk REduction Engineering Laboratory Responsibilities: Optimization of biofilters for the treatment of air-streams containing hazardous wastes. Biodegradation of perchlorate by an anaerobic bacterium. DNA finger printing for rapid analysis of microbial populations. gene probe analysis of catabolic microbial communities
