Jennifer Sahmel, MPH, CIH, CSP, FAIHA

Founder and Managing Principal Scientist

Jenn is a certified industrial hygienist, a certified safety professional, a Fellow of the American Industrial Hygiene Association (FAIHA), and a Research Fellow of the Exposure Science and Sustainability Institute at the University of Minnesota, with over 20 years of experience in human health risk assessment and workplace health and safety. 

 

She has significant experience in exposure assessment practice and methodologies, exposure reconstruction, health risk decision making, OSHA regulatory issues, and safety management systems.

 

Jenn's  areas of expertise include comprehensive exposure and risk assessment strategies, exposure reconstruction, qualitative and quantitative dermal exposure assessment methods, industrial hygiene state of knowledge, Bayesian decision analysis, U.S. EPA exposure assessment tools, Proposition 65 health risk assessment, product stewardship and sustainability issues, industrial hygiene monitoring and data analysis, safety and occupational health management methods, and safety leadership. 

 

Jenn has been involved in characterizing exposure to a variety of chemicals and products for both occupational and consumer product exposure scenarios in a variety of circumstances including for government, academia, law firms, non-profit associations, and private companies. These substances include asbestos, talc, solvents, benzene, gasoline, flame retardants, wood dust, phthalates, lead, beryllium, silica, vinyl chloride, paints/coatings, boiler water treatments, organic solvents, abrasive blasting agents, mercury, arsenic, carbon monoxide, and others.

Heather Avens, PhD, MS, CIH

Senior Health and Safety Scientist

Dr. Heather Avens is a Health and Safety Scientist with over nine years of experience in human health risk assessment. She is a Certified Industrial Hygienist with a PhD and MS in chemical engineering and a BA in biochemistry and molecular, cellular, and developmental biology.

 

Heather's primary areas of expertise includes industrial hygiene, exposure assessment, quantitative exposure reconstruction, indoor exposure modeling, outdoor air dispersion modeling, dermal exposure modeling, accident analysis, probabilistic techniques, and data analysis. She is also skilled at designing, conducting and analyzing exposure simulation studies.

 

She has estimated exposure and risk associated with a variety of substances including asbestos, solvents, gasoline, benzene, polyaromatic hydrocarbons, asphalt, hydrogen sulfide, styrene, lead, cadmium, and phosphorous.

 

Heather has used her expertise to address a variety of exposure scenarios including occupational exposures, consumer use of products, exposures to bystanders, take-home exposures experienced by household contacts of workers, community exposures, industrial accidents, explosions, and spills.

Amber Banducci, MPH

Senior Health and Safety Scientist

Amber is a health scientist with a Master’s of Public Health degree, and a BA in Integrative Physiology and Ecology and Evolutionary Biology.  Her academic training includes epidemiology, biostatistics, environmental and occupational health, public health policy and law, immunology, human physiology, and endocrinology.

 

Amber has experience in exposure and risk assessment, U.S. health and safety regulatory issues, and data analysis. She also has experience performing exposure and risk assessments for consumer products regarding Proposition 65 and other regulatory compliance.

 

Amber’s work has included evaluating exposures, risks, and/or regulations in occupational and consumer use scenarios for cosmetic talc, asbestos, vinyl chloride, benzene, and heavy metals in various products and settings. Some of her research has included potential exposures associated with historical use of cosmetic talc, heavy metal exposure from the consumption of apple juice, and BTEX exposures associated with hydraulic fracturing and crude oil cleanup operations.
