Dr. Shen earned his PhD in Biological Sciences from the University at Buffalo (UB) in 2003, followed by postdoctoral training at UB’s School of Medicine and Biomedical Sciences. He later joined UB's Department of Medicine as a research assistant professor, where he focused on investigating the early events that lead to the development of autoimmune diseases and lymphomas. In 2015, Dr. Shen transitioned into clinical laboratory work, with a special emphasis on developing novel laboratory-developed tests (LDTs) to meet clinical needs. In 2024, he received his Certificate of Qualification (CQ) as a lab director from the New York State Department of Health, with certifications in Diagnostic Immunology, Genetic Testing, Oncology (Molecular and Cellular Tumor Markers), and Virology.

Dr. Patricia A. Mowery-Rushton, a Diplomat of the American Board of Medical Genetics and Genomics in Clinical Cytogenetics, has more than 30 years of experience in cytogenetics and molecular medical genetics. Dr. Rushton received her PhD and clinical fellowship at the University of Pittsburgh, School of Medicine and Graduate School of Public Health.  Before joining KSL, Dr. Rushton was the director of cytogenetics at Signature Genomics, a division of Perkin Elmer, from 2011 to 2014. She has also held leadership positions in cytogenetics at Genzyme Genetics/Integrated Genetics in Santa Fe, NM and Children’s Hospital of Pittsburgh. In her new role as laboratory director and site leader, Dr. Rushton will provide technical expertise in diagnostics and test development for KSL’s genetic testing services. This includes clinical oversight of the cytogenetic and FISH group, whose primary focus is on hematologic oncology with planned growth into solid tumor and prenatal genetics. In the past, Dr. Rushton’s work has focused on cytogenetics and molecular rearrangements in leukemia, and she will translate that experience into the expansion of the genetics program that KSL is developing. Dr. Rushton has a strong record of research and brings an extraordinary and diverse body of expertise and accomplishments to KSL.  As Dr Rushton states “One of my goals is to bring improved client contact to the genetics division, and to ensure that appropriate understanding of what the testing information can provide the physician.  I believe and strive to establish a partnership with the pathologists and physicians in managing patient care”.

Dr. Shanahan received his doctorate degree in immunology from the Temple University School of Medicine in Philadelphia, PA, and trained as a post-doctoral fellow in clinical laboratory immunology at the McGill University Royal Victoria Hospital in Montreal, PQ. He is certified by the American Board of Medical Laboratory Immunologists. He has directed transplant immunology and HLA laboratories at the Erie County Medical Center, Strong Memorial Hospital, Buffalo General Hospital, Upstate New York Transplant Services, and Immco Diagnostics, and has held faculty appointments with the University of Buffalo and University of Rochester Medical Schools.
