Research Interests

Dr. Fornwalt directs the Cardiac Imaging Technology Laboratory at Geisinger, which is a group of engineers, researchers and physician scientists within Geisinger’s Department of Imaging Science and Innovation. Our mission is to improve the lives of patients with cardiovascular disease through the development, implementation, and utilization of state-of-the-art imaging and image processing technologies. Our projects span multiple fields, including but not limited to: Biomechanics, Image Processing, Software Development, Machine Learning, Clinical Science and Medicine, Genomics, Physiology, and Biostatistics and Bioinformatics.
Our three primary focuses are currently:

  1.  Leveraging large electronic health record, imaging and genomic databases to generate new knowledge in cardiology
  2.  Quantifying and understanding sub-clinical cardiac dysfunction in the setting of pediatric obesity
  3.  Using cardiac imaging and other electronic health data to better understand and treat patients with genetic mutations linked to heart disease
