Director, Histocompatibility Laboratory
Technical Director, Molecular Diagnostics Laboratory
Histocompatibility testing for solid organ and bone marrow transplantation, infectious disease monitoring of immunocompromised individuals
I serve as Director of the Histocompatibility section of the Molecular Diagnostics Laboratory at Nebraska Medicine. I am accredited by The American Board of Histocompatibility and Immunogenetics (ABHI) in Solid Organ and Bone Marrow Transplantation, and Histocompatibility Testing for Other Purposes. The laboratory has recently completed the implementation of the first of two key process improvement projects. mTilda, is a computerized lab information system, specifically designed to meet the unique needs of histocompatibility laboratories. This has allowed for generation of concise summary reports available in an easily interpretable format to our transplant teams. Furthermore, mTilda allows the laboratory to store and query original raw data, promoting synergy among clinical, education and research missions at Nebraska Medicine. The second project, currently underway, is validation of NGS technology for high resolution typing of Human Leukocyte Antigen (HLA) genes. This technology represents a major advancement in the field, enabling unambiguous allele assignment from a single run on a single platform, opposed to previous methods requiring maintenance of three separate platforms. This will also streamline HLA typing of both bone marrow and solid organ patients.
I also serve as Technical Director of the Molecular Diagnostics Laboratory. My primary responsibilities as Technical director include the daily supervision of the technical aspects of molecular virology testing in support of the transplant program for Nebraska Medicine. These responsibilities include quality control and assurance, problem solving and compliance for accreditation. I work in collaboration with the Medical Director and associated pathologists to evaluate and validate new testing.
I advocate for the development, improvement and streamlining of technology in order to provide patients with the best possible health care. Outside of my laboratory responsibilities, I serve as an advisory board member for the Nebraska Organ Recovery System and as the Region 8 representative to the UNOS Histocompatibility committee. I am actively involved in both ASCP molecular technologist education initiatives as well as ABHI technologist exam committees.Education and Training
