Aaron Fullerton leads the Investigative Toxicology laboratory within Safety Assessment at Genentech which is focused on the use of in-vitro models to support candidate selection and pre-clinical safety evaluation of a wide variety of therapeutic modalities in the Genentech portfolio. CIVM and MPS approaches comprise a major component of these tools leveraged alongside traditional in-vitro models to provide comprehensive understanding of safety liabilities, mechanisms of drug toxicity and translatability of safety findings from in-vivo pre-clinical animal studies.
