Andy Nguyen received his BS and MS degrees in Mechanical Engineering from the University of Houston. He had been working as a mechanical engineer for 5 years in design/construction industry prior to enrolling in medical school. He obtained his MD degree from the University of Texas Medical Branch-Galveston and received his pathology residency training from the Pathology and Laboratory Medicine Department of the University of Texas Health Sciences Center, Texas Medical Center at Houston. After completing his residency, he stayed on as a faculty member and is currently a Full Professor of Pathology and Laboratory Medicine. He has served as the medical director of Hematology and Coagulation Laboratory at Memorial Hermann-Texas Medical Center (1993-2021). He has clinical and research interests in hematopathology, coagulopathy, and pathology informatics. Dr. Nguyen has published numerous scientific papers, written many invited review articles, and contributed to several textbooks. He has also received multiple teaching awards from the Pathology Department and from the Office of the Dean.

Key clinical and scientific contributions:

-With an extensive background in computer programming, he has developed decision-support software modules covering various aspects in hematology, coagulation, and molecular hematopathology (

-Established a new hemotherapy service at Memorial Hermann Hospital-Texas Medical Center in 2012 to successfully provide transfusion support for heart-transplant and ventricular-assist device patients. He has served as the medical director of Hemotherapy service for advanced heart failure patients at Memorial Hermann-Texas Medical Center (2012-2014)

-Published research findings on significant topics in benign/malignant hematologic disorders, coagulopathy, hematologic mutations, and pathology informatics.

-Currently (2022) chairing the whole slide imaging (WSI) task group in the department of Pathology to select and implement WSI scanners to allow pathologists to sign out pathology cases using digital images.

-His current research interests lie in designing deep learning software (an advanced form of artificial intelligence) for screening and diagnosis of pathologic lesions using whole slide imaging (WSI) from various organ systems including lymphoma (lymphoid system), carcinoma (breast). Of particular interest is his current research to screen for breast cancer metastasis with only a small set of image patches from any sentinel lymph node to detect changes in tumor environment and not the tumor itself. This approach is unique since it provides a very rapid screen rather than an exhaustive search for tumor in all fields of all lymph nodes. His group obtained excellent predictive results for cancer metastasis in this study, which provide a proof of concept for incorporating automated metastatic screen into the digital pathology workflow to augment the pathologists’ productivity. Results from these studies have been presented at various national meetings (United States & Canadian Academy of Pathology annual meeting, March 19 – 24, 2022, Los Angeles, CA; Texas Society of Pathologists Meeting, April 1-3, 2022, Houston, Texas; The 8th Digital Pathology & Artificial Intelligence Congress, June 14-15, 2022, New York, NY). Since Deep Learning model is not specific to any pathology subspecialties, the successful application of this model in breast cancer screening may potentially expand to other subspecialties in pathologies (GI, GU, renal, etc.) with appropriate training and testing cases. He plans to collaborate with colleagues in multiple subspecialties in this direction.

-Ongoing Pathology informatic outreach for underdeveloped countries through online telepathology with WSI, online conferences, and teaching trips.
