Pawel Mroz

Assistant Professor


Dr. Pawel Mroz is a member of the department's Division of Molecular Pathology and Genomics. He is board certified in anatomic and clinical pathology with expertise in hematopathology and molecular genetic pathology and he will provide primary service in the Molecular Diagnostic Laboratory as well as hematopathology.Dr Mroz's early research interests included translational applications of photodynamic therapy for cancer treatment as well as investigating the role of tumor associated antigens and T regulatory cells in anti-tumor immune response. Currently his research interests are focused on two areas: Droplet digital polymerase chain reaction (ddPCR) and next-generation sequencing (NGS) technologies. Droplet digital PCR (ddPCR) is a novel diagnostic platform that provides absolute quantification of amplification targets by partitioning and separately analyzing each PCR reaction. ddPCR is a refinement of conventional and quantitative PCR as it demonstrates robust performance characteristics and may offer improved detection of low-level disease. ddPCR has the potential to become an especially valuable diagnostic and prognostic tool in hematologic malignancies like acute lymphoblastic leukemia or acute myeloid leukemia as it may allow for earlier detection of relapse or persistence of disease.Next-generation DNA sequencing is beginning to be applied in the initial diagnosis and classification of a growing number of malignancies. Dr Mroz has experience in the clinical application of NGS but wants to focus on developing new translational applications for NGS in the research setting that over time can be brought to the clinic. The technical dimension of NGS is fairly well understood but its use in characterizing hematologic malignancies is at an early stage of development. Dr Mroz sees opportunities for adding new NGS applications for better characterization and classification of hematologic malignancies.
