Bernard Gadagbui holds a Ph. D. in Environmental Health and Toxicology, a M. Sc. in Biochemistry from the University of Bergen, Norway, and B. Sc. (Hons.) in Biochemistry with Chemistry from the University of Ghana. Dr. Gadagbui joined the staff at the Toxicology Excellence for Risk Assessment (TERA) in 2004 as a toxicologist after a combined 8-year toxicologist position at the University of Florida and the Bureau of Pesticides of the Florida Department of Agriculture and Consumer Services (FDACS). He has a wealth of research and teaching experience in environmental toxicology, experience in evaluating human health risks posed by chemicals including pesticides and in developing health-related toxicity values for chemicals, and is familiar with state and federal pesticide regulations. Dr. Gadagbui is interested, among others, in the use of mode of action and mechanisms of toxicity of occupational and environmental toxicants and carcinogens in risk assessment.

Dr. Gadagbui is a founding member of ASTS and was the first Publicity Secretary, a position he held for several years. Prior to becoming the Vice President, he has always been active and most often contribute to the smooth running of ASTS from behind the scenes. He was also instrumental in recruiting Dr. Michael Dourson, President of TERA, as one of the advisors of ASTS.

Dr. Gadagbui has also been active in toxicology societies where he has held or currently holds leadership positions. These include: Toxicologists of African Origin (TAO), a Specialty Interest Group of the Society of Toxicology (SOT) (first President, 2008-2009); Ohio Valley SOT (OVSOT) (Councilor), and Ohio Chapter of the Society for Risk Analysis (OSRA) (Secretary).

Dr. Gadagbui has received numerous awards for his work. Most recently, he led a project that received honorable mention in 2010 for the Alice Hamilton award for top risk assessment work at NIOSH. He also led a team of TERA scientists that won the 2010 Risk Reduction Achievement Award from the Alliance for Chemical Safety, a regional professional organization with a mission to promote public understanding and involvement in chemical risk management.

Dr. Gadagbui believes in the noble goal of ASTS to be a leader in promoting the acquisition and utilization of knowledge of toxicological sciences relevant to Africa, transferring this knowledge to the African continent and fellow Africans, and bringing together African and non-African toxicological scientists to dialogue and effectively strategize on how to move toxicological sciences forward on the continent. He pledges to continue the programs instituted and initiatives started by the past Executive Committees, expand membership, vigorously pursue formation of regional or country chapters on the continent, identify and seek solutions to the challenges and needs for our continent, engage scientists, opinion leaders, and stakeholders in environmental and health issues on the continent, and seek necessary funds for all our activities in North America and in Africa. Dr. Gadagbui believes that there is the need to become more visible to the national and international communities and to continue to build a more viable organization. He pledges to work with the Executive Committee to effectively promote the Society.

Past President: Lilian G. Yengi
Yengi Consulting Service
Email: lilianyengi@gmail.com

Lilian Yengi is currently an Associate Director in the Drug Metabolism and Pharmacokinetics (DMPK) department at AstraZeneca Pharmaceuticals, where she heads a group of scientists responsible for conducting in vitro drug metabolism studies to support the discovery and development of anti-cancer and anti-infective drugs. Prior to that, she spent 10 years in the Drug Safety and Metabolism (DSM) department at Wyeth Pharmaceuticals (now part of Pfizer) where she led a team responsible for assay development and conducting in vitro studies to support multiple therapeutic areas. She represented Drug Safety and Metabolism on cross-functional teams, responsible for formulating and implementing DMPK strategies to support clinical development plans through phase 3. She has extensive hands-on experience and expertise in several in DMPK disciplines including drug-drug interactions (induction, inhibition), metabolic stability and reaction phenotyping, as well as pharmacogenomics and toxicogenomics. She has authored several documents for regulatory submissions and preparing responses to regulatory queries.

Lilian obtained a BSc in Biochemistry and Biology from Keele University (UK), a Masters degree in Clinical Biochemistry from Leeds University (UK) and a Ph.D. in Molecular Genetics from Staffordshire University (UK), with Professor RC Strange as adviser. As part of this program, she studied the influence of genetic polymorphisms in cytochrome P450s and GSTs on disease susceptibility, with a particular emphasis on cancer and inflammatory-mediated diseases. She was involved in the identification of novel polymorphisms that, in combination with environmental factors, increased susceptibility to certain cancers such as cervical and skin cancers. She then did a 2-year postgraduate fellowship with Professor Roland Wolf at the Biomedical Research Center, Dundee University (Scotland) where she was involved in setting up pharmacogenomics tools to study individual responses to drug therapy. She has several peer-reviewed publications and is a member of the International Society for the Study of Xenobiotics (ISSX) and the Society of Toxicology.
