  • Andrew Douglas Lab

    Research in the Andrew Douglas Lab investigates topics within the field of biomedical engineering. Our studies primarily focus on soft biological tissues and organs, such as the heart and tongue. Our current research areas include the nonlinear mechanics of solids, the mechanical response of compliant biological tissues, finite deformation elasticity, and the static and dynamic fracture of ductile materials.

    Research Areas: biomedicine, soft tissues, biomedical engineering, organs

    Medicine

    The Cardiology Bioengineering Laboratory, located in the Johns Hopkins Hospital, focuses on the applications of advanced imaging techniques for arrhythmia management. The primary limitation of current fluoroscopy-guided techniques for ablation of cardiac arrhythmia is the inability to visualize soft tissues and 3-dimensional anatomic relationships.

    Implementation of alternative advanced modalities has the potential to improve complex ablation procedures by guiding catheter placement, visualizing abnormal scar tissue, reducing procedural time devoted to mapping, and eliminating patient and operator exposure to radiation.

    Active projects include
    • Physiological differences between isolated hearts in ventricular fibrillation and pulseless electrical activity
    • Successful ablation sites in ischemic ventricular tachycardia in a porcine model and the correlation to magnetic resonance imaging (MRI)
    • MRI-guided radiofrequency ablation of canine atrial fibrillation, and ...diagnosis and intervention for arrhythmias
    • Physiological and metabolic effects of interruptions in chest compressions during cardiopulmonary resuscitation

    Henry Halperin, MD, is co-director of the Johns Hopkins Imaging Institute of Excellence and a
    professor of medicine, radiology and biomedical engineering. Menekhem M. Zviman, PhD is the laboratory manager.
