Dr. Hewitt earned his MD at University of Texas Medical School at Houston, and PhD at the University of Texas Graduate School of Biomedical Sciences, completing my thesis in genetics at MD Anderson Cancer Center. He completed my residency in Anatomic Pathlogy in the Laboratory of Pathology, NCI, and is board certified in Anatomic Pathology.  Dr Hewitt led the The Tissue Array Research Program (TARP Lab) from 2000-2014 and the Applied Molecular Pathology Laboratory (AMPL),  a dual division (CCR and DCEG) effort from 2009 till 2014. In 2014, Dr Hewitt initiated the Experimental Pathology Laboratory, within the Laboratory of Pathology.

Dr. Hewitt is a member of the Clinical Laboratory Standards Institute Immunology & Ligand Assay Consensus Committee, and serves as co-chair of the Subcommittee on Immunohistochemical Assays and a consultant to the Hematology and Pathology Devices Panel, Center for Devices and Radiological Health, Food and Drug Administration. Dr Hewitt has co-authored more than 225 articles and servers on the editorial board of four peer-reviewed journals.
