I earned my MD at University of Texas Medical School at Houston, and my PhD at the University of Texas Graduate School of Biomedical Sciences, completing my thesis in genetics at MD Anderson Cancer Center. I completed my residency in Anatomic Pathlogy in the Laboratory of Pathology, NCI.

The Tissue Array Research Program (TARP Lab) was initiated in 2000. The Applied Molecular Pathology Laboratory (AMPL) was initiated as a dual division (CCR and DCEG) effort in 2009.


The Tissue Array Research Program (TARP Lab) specializes in the construction of tissue microarrays (TMAs). We are active in the development of new methodologies and technologies surrounding the use of TMAs.

The Applied Molecular Pathology Laboratory (AMPL) is a collaboration between the CCR and DCEG to facilitate high-throughput tissue pathology based assays for biomarker development and validation.
