Implantable Device for Spinal Cord Injury
The HEPIUS Lab includes team members from the JHU School of Medicine, School of Engineering, Applied Physics Lab, and multiple companies. Together, we are creating a system of interactive devices based on ultrasound technology for continuous and active monitoring of patients with spinal cord injury. My contribution is to enable automated calculation of blood perfusion at the injury site.
Automating Cardiac Image Segmentation
Segmenting the left ventricle myocardium is a critical first step to analyzing heart pathologies. We developed a deep learning segmentation algorithm tailored to clinical application. This work out of the Trayanova Lab at JHU has been published in the Cardiovascular Digital Health Journal and was selected for poster presentation at the 2020 American Heart Association Conference.
