Christian is a Senior lecturer in Environmental toxicology and director of the Chemical Safety and Applied Toxicology (CSAT) laboratories at the School of Risk and Safety Sciences.
He is the Chairperson of the School OH&S Committee, and heads the School emergency team.

Christian academic interests cover toxicology, environment, safety and management systems. He lectures in:

• Environmental science,
• Environmental management systems,
• Environmental auditing, and
• Safety health and environmental practices.

Christian research interests range from the impact of exposure to UV radiation on humans to the application of in vitro techniques for assessing environmental pollution problems.

Research projects in progress:

• In vitro toxicology methods development for application to products testing (raw materials, cosmetic formulation etc)
• Nanoparticles toxicity on human derived cell cultures and human skin
• The toxicity of welding fumes in vitro and in vivo, occupational exposure context.
• Chemical mixtures, their synergistic interactions and cytotoxicity
• Toxicity assessment of environmental pollutants released into an aquatic environment.
• Investigation of the effect of altered NAD levels on DNA repair and survival in fibroblasts & keratinocytes (skin) cells following oxidative and U.V. damage.

He is also interested in a range of research areas involving toxicology and environmental areas:

• Comparison between quantitative human risk assessment and microbial risk assessments and their application in biological control agents,
• The application of mammalian cells in screening environmental stressors,
• Environmental risk assessment and soil quality,
• The application of environmental management systems to small and medium enterprises in Australia,
• The toxicity of artificial sun tanning chemicals on humans and their genotoxic and immunotoxic potential,
• The toxicity of car exhaust fumes on human lungs- an in vitro approach,
• Toxicity of Volatile Organic Compounds (VOCs) from engine combustion on driver in car cabin using a dynamic in vitro technique,
• Comparative analysis of patient health data mapping to air quality data- an epidemiological study,
• The effects of cumulative car exhausts on cyclists’ respiration. In vitro versus in vivo correlation.
