2011 Recognition Awards

Kevin Crofton, PhD, and Manfred Liebsch, PhD Win 2011 CAAT Recognition Award

The CAAT Recognition Award honors an organization or individual that has made an outstanding contribution to the field of the 3Rs (reduction, refinement, replacement), the development of alternative methods, or the field of in vitro science. The 2011 recipients of this award are Kevin Crofton, PhD, and Manfred Liebsch, PhD.

Crofton was chosen from a list of international nominees for an exceptional body of work in the field of neurotoxicology, especially in the area of developmental neurotoxicology (DNT).
He is an acting assistant director in the National Health and Environmental Effects Laboratory, U.S. Environmental Protection Agency, Research Triangle Park, North Carolina. Crofton has worked as a toxicologist at EPA since 1986, receiving Scientific and Technological Achievement Awards and a Gold Medal for Commendable Public Service.  

Crofton’s interests and expertise include areas such as developmental neurotoxicity, the cumulative risk of thyroid disruptors and development of alternative testing methods. He served as the leader of the Developmental Neurotoxicity Team for many years, with the goal of fostering the development of alternative models for screening chemicals for developmental neurotoxicity. His current efforts include development of in vitro and alternative methods for detecting thyroid disrupting chemicals.

His professional activities include membership in several scientific societies and participation on many professional review boards. He has presented invited lectures for a variety of government agencies in Europe, Canada and the U.S., and for professional societies and universities. He has authored or coauthored over 125 peer reviewed publications.

Crofton earned his PhD in Toxicology from the University of North Carolina, Chapel Hill. He is currently an adjunct associate professor in the Department of Environmental and Molecular Toxicology at North Carolina State University and the Curriculum in Toxicology at the University of North Carolina at Chapel Hill.  

Manfred Liebsch was selected from a list of international nominees for outstanding expertise in and dedication to the assessment, validation and promotion of alternative methods.
Liebsch is the Scientific Director of Germany’s Federal Institute for Risk Assessment (BfR) and head of the Centre of Alternative Methods to Animal Experiments (ZEBET) at the BfR. He has served as main contractor, co-coordinator, participant or consultant on a variety of successful validation studies of alternative in vitro methods, both at the national and the European level. His work has focused on the fields of topical toxicity (eye- and skin-irritation and corrosion, phototoxicity and skin absorption) and ecotoxicology (acute aquatic toxicity). Liebsch also provides Expert Consultancy in the validation of new toxicological methods for hazard identification in National, European, and International Working Groups, including the ECVAM Scientific Advisory Board, the OECD Test Guidelines Program, and ISO 194. He also played a key role in convening the Working Group M12 for Biological Evaluation of Medical Devices. He has published numerous papers and is a frequent invited speaker at conferences.
Liebsch earned his diploma in biology (zoology, biochemistry, microbiology) and his doctorate at the University of Hamburg, Germany.  He carried out postgraduate research in parasitology at Hamburg and also served as a lecturer in zoology, physiology and parasitology.
