The Center for 21CT develops tools and technologies in the areas of biokinetics and metabolism, biological pathway response and pathway-based toxicology, evidence-based toxicology, and rapid exposure estimation. We integrate these tools and technologies with industry-specific knowledge and expertise, to provide strategies for application of computational and in vitro models to make risk-based decisions that meet the specific needs of the client. Our scientists conduct experimental studies by partnering with laboratories that offer expertise and critical technologies to meet our clients' needs. We work collaboratively with clients and laboratories at CROs, universities, and non-profit organizations to design experimental workflows, custom models, and assays, in addition to providing oversight and management of laboratory work, including evaluation of data quality and data analysis.
