Medical Technology of the Future

We are excited to announce the publication of our latest work in Nature Biomedical Engineering. In collaboration with the John Rogers' Lab, we validated their novel electrode design by simultaneously recording while collecting optically mapping images in an in-vitro Langendorff perfused rabbit heart. This device platform overcomes issues associated with chronic implantation of metal oxide electrodes (e.g. intrusion of biofluids into underlying electronics and current leakage).


Yesterday evening was the yearly GWU SEAS R&D Showcase. Students from all of GWU's engineering disciplines prepared posters of their work and were judged by a panel of investigators and volunteers from industry. We would like to congratulate Chris Gloschat for being awarded 3rd Place Best Experimental Poster and Jaclyn Brennan for being awarded a Runner-Up Student Travel Award!

Leducq Foundation funded our transatlantic network of excellence: RHYTHM!

Our transatlantic network consisting of 6 universities received funding from the Leducq Foundation. Our project is titled Repolarization HeterogeneitY imaging for personalised Therapy of Heart arrhythMia (RHYTHM). Project was among only 5 funded proposals selected from 120 submitted.
