Profile Picture

Available: 04/21/17, Expires: 11/30/23

Cardiovascular group in the Massachusetts General Hospital (Harvard Medical School) is seeking multiple qualified and enthusiastic students interested in experimental and computational cardiac electrophysiology.

Projects are student specific, please contact for more details.
Lab Mission: To use experimental and computational approaches to study the mechanisms of cardiac arrhythmias from the myocyte to the whole organ level

Research Area I: The project involves participating in clinical trials currently underway in the Division of Cardiology at Massachusetts General Hospital, with the intent to diagnose, prevent or treat atrial or ventricular arrhythmias. The prospective applicant will also participate in developing and/or employing signal processing tools of electrocardiographic signals.

Research Area II: The prospective applicant will be performing experiments in cardiac myocytes using state-of-the-art methodologies, including whole-cell patch-clamping and fluorescence imaging, aiming in (i) improving our understanding of the patho-physiology of myocytes from failing hearts and (ii) designing novel therapies to slow or inhibit the progression of the disease.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
