As the principal officer of ToxWorks, Dr. Cruzan provides:
- Business unit interactions
- Literature reviews
- Toxicological evaluations
- Analysis of regulatory interactions
- Litigation support
- Study design and monitoring to trade associations and individual companies on a consulting basis
Prior to establishing his own toxicology consultancy, Dr. Cruzan worked for Rohm and Haas and Mobil Oil Company for over 30 years. He is a well-known expert in the toxicity and oncogenicity of styrene, having authored and co-authored numerous research papers on:
- Styrene inhalation
- Toxicity
- Metabolism
- Ecotoxicology
- The pharmacokinetic modeling of styrene and styrene oxide respiratory-tract dosimetry
He has published over 25 such articles in peer-reviewed journals, including the review article “Styrene Metabolism and Toxicokinetics in the SIRC Review” (1994), and, more recently, “Two Generation Reproduction Study of Styrene by Inhalation in Crl-CD Rats”. (Birth Defects Research Part B: Developmental and Reproductive Toxicity, 2005).

Areas of Expertise, Discipline, Relevant Experiences
Experience:
Dr. Leavens has authored and coauthored 12 articles and 20 abstracts in peer-reviewed journals on physiology and pharmacokinetics. This includes articles on the interaction of butadiene and styrene in rats. She is also the author of Pharmacokinetics of 1,3-butadiene for EPA’s Health Assessment of 1,3-butadiene. She received the Level III EPA Scientific and Technology Achievement Award in 2004.
Areas of interest:
Dr. Leavens main research interests center on:
- Kinetic modeling, particularly physiologically based modeling of volatile and nonvolatile compounds
- Controlled clinical studies with humans via oral and dermal exposure
- In vivo metabolism studies with rats and mice with volatile and nonvolatile compounds
Dr. Leavens’ doctoral research involved physiologically based pharmacokinetic modeling of the metabolic interactions of 1,3-butadiene and styrene. It also included the assessment of alterations in genotoxic response of male mice following inhalation exposure to mixtures of both compounds.
She designed a whole-body, dynamic inhalation system to expose individual mice to gases and vapors. She measured changes in uptake of styrene and butadiene and blood concentrations of reactive metabolites in mice exposed to mixtures of both chemicals. She also measured changes in the genotoxicity of butadiene in mice exposed to mixtures of butadiene and styrene compared with mice exposed to butadiene alone.

Areas of Expertise, Discipline, Relevant Experiences
Areas of Expertise:
Dr. Rabovsky is a public health scientist with a strong background in:
- Occupational and environmental health
- Xenobiotic metabolism
- Public health policy.
Experience:
In her 14 years with the California EPA, she participated in development of non-cancer chronic inhalation reference exposure levels (REL). Dr. Rabovsky prepared and contributed to chapters in numerous state documents, such as Public Health Goal, Cancer Hazard Identification, in such topics as:
- Cancer bioassays
- Genotoxicity
- Metabolism and toxicokinetics
- Non-cancer toxicity
She often presented her findings at scientific meetings and in peer reviewed publications. She published numerous articles, including Risk assessment approaches to developing proposed non-cancer chronic ambient inhalation reference exposure levels (RELs) for styrene (STY) and styrene oxide (SO) (The Toxicologist. 30:148 1996).
