Description of Clinical Expertise

As a translational immunologist my interest is in improving the potency and safety of adoptive immunogene therapy via correlative studies and product/process development. My translational interest also lies in streamlining the immunogene manufacturing process while maintaining or improving product potency.

Description of Other Expertise

Immunology of human allogeneic hematopoietic stem cell transplantation.

Description of Research Expertise

My expertise is in human T cell immunology and immunogene therapy, understanding and improving the anti-tumor efficacy of gene-engineered T cells for the treatment of cancers.
