My research focuses on optimizing clinical trial design by pre-clinically evaluating pharmacokinetics and CNS drug delivery in an animal model. This information is used to determine ideal route of drug delivery (systemic, intrathecal, intranasal, convection-enhanced delivery) to achieve biologically effective dosing at the tumor site. 

Our animal models have chronically indwelling IV and CSF access, facilitating serial assessment of drug exposures in CSF fluid and the blood compartment simultaneously, allowing for multiple sample collection over time for PK studies. This model has been used to determine CSF and extracellular fluid penetration and toxicities of agents in development for patients with CNS tumors. 

Tumor type: all children's brain tumors; special focus on brainstem glioma.
