As medical director of the clinical laboratories, I consider every patient to be my patient. Laboratory testing is a common and necessary part of health care since tests are pivotal to determining health status and next steps. I want every patient to receive the same level of accurate, timely, high quality laboratory test results that I expect for my own family who also receive care here. I also believe that it is our role as an academic health center laboratory to support complex care that might not otherwise be available in our region, as well as provide the everyday services that keep our community healthy.
Dr. Howell's clinical interests as medical director focus on improving laboratory quality and efficiencies, including the adoption of new leading-edge technologies. As a cytopathologist, Dr. Howell enjoys providing diagnostic service through the evaluation of samples from minimially invasive sampling methods, including fine needle aspiration biopsies, brushings, washings, and fluids.
Dr. Howell's research interests have focused on factors influencing women's careers in biomedical science, and work-life balance. She also has a strong creative interest in health care delivery science and the role of new technologies, including artificial intelligence, and standardized guidelines and practices in improving efficiencies and accuracy in pathology and lab testing.
