Dr. Jones has 17 years of microbiology experience in academia and the consulting industry, on projects in the United Kingdom, Belgium, Brazil, Canada, China, France, India, Spain, and the United States. He specializes on microbial risk assessment, microbial contamination of products and processes, microbial aspects of industrial hygiene, microbial degradation of contaminants, microbial regulatory compliance and applications of biotechnology on behalf of public and private sector clients.

Dr. Jones has conducted investigations, characterizations and microbial risk assessments (qualitative and quantitative - QMRA) of microbial contamination of ground water, potable water, process water, recreational water, storm water and other surface waters for a number of specific microbial pathogens or fecal indicator bacteria (FIB). These investigations have used traditional microbiology techniques as well as molecular approaches including bacterial source tracking (BST) and 16s ribosomal RNA analysis. Investigations have included assessing the potential sources of fecal bacteria at a storm water discharge from a landfill in Hawaii and at a coastal power plant in Southern California, assessing municipal sewer integrity, FIB in ground water near a waste water treatment plant for potential releases, assessment of entrainment of a waste water treatment plant discharge into the near shore environment, the cause of fish and bird kills at a golf course lake, cyanobacteria in lead mine tailing ponds, FIB at coastal refineries, and FIB in potable water supplies. Dr. Jones has investigated the causes of microbial contamination in industrial hygiene cases, including Legionella, mold, Hantavirus, and Salmonella. Dr. Jones has also used BST in assessing potential sources of contamination in food, as well as conducting QMRA of food contamination events, traceback analysis of microbial contaminated food, health risk assessments of food contamination and characterization of pharmaceutical contamination. Dr. Jones has conducted investigations of microbial contamination of retail consumer products, systems and industrial processes.

In addition, Dr. Jones has characterized and quantified biodegradation rates of aromatic, straight chain and chlorinated hydrocarbons, metals, PAHs, PCBs, and pesticides, and assessed potential constraints to biodegradation with the use of the biosensor HK44. He has also assessed the impact of in-situ chemical oxidation to remediate trichloroethene (TCE) using functional gene analysis, microbial community fingerprinting with terminal restriction-fragment length polymorphism (TR-FLP), and metagenomics with microarrays. Other microbial projects have included industrial hygiene assessments of microbial growth after water intrusion events, microbial efficacy testing of medical treatment and recycling systems, exit audits of biotechnology facilities, and process treatment efficacy for food production systems.

He has also supported clients with federal regulations including Toxic Substance Control Act (TSCA) Microbial Commercial Activity Notice (MCAN) preparation for ethanol refineries and algal biofuel producers, Food and Drug Administration (FDA) Generally Recognized as Safe (GRAS) notifications, and Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) antimicrobial product registration.

In addition to consulting work, he has lectured at the School of Biomedical Sciences, King’s College London.

Project Experience

Microbial Risk Assessment and Public Health

Retained as an expert witness by Waste Management Inc., defendants in a criminal case involving alleged violations of the Clean Water Act. Tasks included characterization and evaluation of the presence of fecal indicator bacteria (FIB) in storm water discharge, characterization of local sources of sewage sludge and identification of potential sources of FIB upgradient and downgradient of the alleged source.

Conducted an investigation into the source of Salmonella in a food ingredient, testing included reviewing batch analysis data, conducting on site sampling at two facilities and using BST techniques to differentiate potential human and non-human sources of Salmonella.

Developed bacterial source tracking (BST) techniques to assess the potential sources of fecal bacteria impacting the City of Huntington Beach and the adjacent State beach in Southern California. The assessment focused on terrestrial and marine sources of bacteria associated with the AES power plant, and required a continuous three-month sampling program of coastal and freshwater samples with a two-week period of round the clock sampling. Cooling water discharge was modeled using Fluorescein dye and oranges released from the power plant cooling water discharge.

Conducted an investigation into Aeromonas hydrophila as the cause of fish and bird kills at two lakes in Southern California in conjunction with the Veterinary School of Medicine at UC Davis. Developed an Aeromonas monitoring program for the two lakes using 16S ribosomal gene analysis in collaboration with the University of Oregon, and assessed likely occupational health risk and microbial risk.

Conducted a QMRA of Salmonella in dog kibble from both the canine exposure and human exposure routes. Screening-level health risk assessments of microbial contamination of food and beverage products.

Litigation support in a Hantavirus contamination case, and several alleged Legionella exposure cases.

Microbial risk assessment of fungal contamination in a food product.

Assessed the uptake of particulate metals by microorganisms at a lead mine tailing pond in Idaho, tested rates of uptake by the cyanobacteria and developed remedial methods to mitigate off-site dispersal of the cyanobacteria and the particulate lead contained within the cyanobacteria.

Microbial and Biotechnology Regulatory Compliance Prepared a GRAS notification submittal for a Bacillus coagulans probiotic supplement.

Prepared whitepapers on the use of metagenomics for developing bioforensic signatures for Chemical, Biological, Radiological, Nuclear and Explosive (CBRNE) incidents for a confidential client, and on the generation of features of significance in bioforensics from genetic material for the same client.

Assisted a tile-manufacturer in attempting to register a tile product with the United States Environmental Protection Agency (USEPA) FIFRA antimicrobials group. Activities included reviewing existing efficacy studies and developing novel studies to present to the USEPA antimicrobials group.

Prepared microbial characterization of B. coagulans, cyanobacteria and green algae used as components in a beverage in support of a GRAS notification submittals.

Prepared two MCAN exemption submittals associated with the proposed use of genetically engineered yeast strains at two cellulose-based ethanol pilot plant refineries. The submittals required a detailed understanding of the host microbial strain and the donor microorganism, as well as biosafety components for the treatment of any waste containing the genetically modified yeast strains.
Developed microbial assessment protocols in accordance with Good Manufacturing Practices (GMP) at paper mills and paper packaging facilities for food-contact substances. The microbial assessment protocols were developed to reduce the microbial burden associated with the food-contact paper products.

Industrial Hygiene

Litigation support in multiple alleged asbestos exposure cases. Tasks included reviewing files, documenting occupational chronology, and developing occupational exposure to specific sources of asbestos.

Assessed occupational exposure to sodium hydroxide and phosphoric acid during specific cleaning tasks at a food preparation facility. Provided litigation support on the case.

Conducted over 50 tenant exit audits of biotechnology facilities operating in South California, Texas, and Colorado. The audits including reviewing the biological inventory and biosafety level (BSL) in use at each facility to determine if appropriate decontamination procedures had been followed, and a review of radioactive material use to confirm appropriate decontamination of radioactive material and decommissioning of the tenant space.

Mold assessment and abatement at biotechnology research facilities, medical warehouse facilities and private residences.

Developed and implemented microbial efficacy and pharmaceutical removal test methods for two recycling treatment systems of medical red bag waste and sharps containers. The treatment systems were designed to enable the recycling of glass, plastics, and metal contained in sharps waste. The treatment systems were designed to reduce the microbial burden using steam treatment and in one system to concurrently remove pharmaceutical residue.
