Dr. Hanna Jensen is our research support faculty. Dr. Jensen received her medical training in her native Finland, where she also completed her PhD in cardiovascular surgery and a doctorate in medical science. Her postgraduate surgical training took place in Finland and in Denmark. She completed a Post-Doc at one of the largest pediatric cardiac centers in Europe, the Great Ormond Street Hospital for Children in London, United Kingdom. She then worked as a Clinical Research Associate at the Emory Structural Heart and Valve Center in Atlanta prior to her relocation to Arkansas. Before joining UAMS full time, she has worked as a Clinical Assistant Professor in Biomedical Engineering at the University of Arkansas. Dr. Jensen has extensive experience in experimental, translational, and clinical research. Her main goal is to coordinate research projects, and support students, residents, and faculty in their research efforts. She conducts meetings every Friday morning for anyone interested in taking up research projects.

There is an ongoing research collaboration between UAMS radiology and the UARK Computer Science department Computer Vision and Image Understanding (CVIU) Lab. Headed up by department Chair Dr. Arabinda Choudhary and CVIU lab director Dr. Khoa Luu, this collaboration is in its early days, but has already led to a number of grant applications and publication submissions by faculty, graduate, and post-graduate personnel from both institutions. Areas of ongoing research include correction and post-processing of chest radiographs, noise reduction in low-dose CT scans, and annotation tools which will allow faster and more accurate training of future machine learning algorithms. Other AI research at the UAMS radiology department includes collaboration between our Quantitative Imaging lab and the UAMS Myeloma Center, investigating quantitative markers of bone health and their effect on patient outcomes. AI research at UAMS involves personnel of every level, from support staff and medical students up to the department chair, and much of the active work has been led by residents and junior faculty.

Any questions about the information below, any additions or edits? Or simply interested in getting involved? Please email Dr. Hanna Jensen hkjensen@uams.edu. Radiology Research Meeting occurs every Friday 8-9am via Zoom, please email Dr. Jensen for details.
