Omer Inan, PhD

Visiting Scholar

Department of Electrical Engineering

Starting August 1, 2013, I will be joining the ECE School at Georgia Tech as an Assistant Professor.




Research Interests

I am interested in designing medical devices for clinically-relevant applications, and translating them from the lab to patient care. In my current and previous research, I have invented novel technologies for biomedical sensing, with a strong focus on non-invasive cardiovascular diagnostics at home. For my doctoral work, I modified a home weighing scale with a custom analog front-end and innovative signal processing algorithms to robustly estimate changes in cardiac output and contractility -- these parameters can normally only be measured reliably in the clinic, with expensive tools and a trained medical professional administering the test. This work could help improve the management of heart failure patients at home by providing doctors valuable diagnostic information that could allow them to remotely adjust therapies according to the changing needs of the patient.
