The Hamner Institutes for Health
Sciences is an independent, nonprofit
organization that offers an open,
collaborative and cross-disciplinary
approach to translational biomedical
research. Based in Research Triangle
Park, North Carolina, The Hamner strives
to act as a catalyst with global academic
institutions, industries, and government
to support innovative research and
rapid technology development. Novel
technologies used at The Hamner
include genomic and bioinformatic
approaches for improving toxicity
testing, in silico models for predictive
toxicology, in vitro models that utilize
human cells or cell lines to evaluate
perturbations of cellular responses,
and in vivo models to elucidate genes
that play a role in susceptibility to druginduced toxicities.
Over the past 37 years, Hamner
scientists have been recognized worldwide for their research contributions
and training programs in environmental
health sciences and chemical risk
assessment.
