Mac has over 30 years’ experience in chemistry, biochemistry and toxicology with major companies (ICI, Zeneca and Syngenta) and was an investigative toxicologist at the world-famous Central Toxicology Laboratory (CTL) from 1979 to 2003. He is a recognised expert in the investigation and understanding of the role of metabolism and kinetics in species-specific responses to xenobiotics and has made numerous contributions in this field of regulatory science.

In addition to these key scientific skills, Mac also has significant experience of project management and information systems management. He was responsible for development of appropriate in-house ‘decision-making’ safety information for potential new products, prior to defining and managing the development of safety data packages and science-based registration strategy for new product registration and/or defence. More recently Mac has been involved in REACh technical dossier compilation and project management, particularly for substances with complex toxicology issues.
