BME researchers develop novel approach to defibrillation

Three research labs at Hopkins—the Tung and Trayanova labs in Biomedical Engineering and the Berger lab in Cardiology—have combined forces to investigate the efficacy of high frequency alternating current as an alternative to conventional waveforms used to defibrillate the heart. This research could lead to defibrillator devices that apply a more gentle, less painful current […]

Karchin paper highlighted in editorial

Rachel Karchin, assistant professor of the Department of Biomedical Engineering and the Institute for Computational Medicine, and colleagues have created a computer program to help predict which changes in the DNA code may cause pancreatic cells to become cancerous. Cells in the body accumulate DNA changes over time as a result of the normal aging […]
