Research Interests

Dr. Manbachi’s research interests include engineering design, development and clinical validation of acoustic probes (ultrasound transducers) and minimally invasive medical devices for clinically inspired diagnoses and treatments.

With a research focus on acoustic probes and ultrasound transducers, the range of applications for these probes vary from imaging and image-guided interventions, to therapeutics (oncology ablations), Piezo-electric cutters, Thermometry, cell-localization and Neuromodulation.

Dr. Manbachi’s teaching activities include mentorship with BME Design Teams (teaching capstone design, innovation and entrepreneurship) as well as close collaboration with clinical experts in Surgery, Radiology and Human factor experts at Johns Hopkins.

His doctoral studies (conducted at the University of Toronto, under the supervision of Dr. Richard S.C. Cobbold) included design and development of ultrasound-guided spine surgery, which resulted in spinning off a startup. Subsequent to that, and prior to joining Johns Hopkins, he was a postdoctoral fellow at Harvard-MIT Division of Health Sciences and Technology (2015-16). He also has industry experience working at Stryker Navigation headquarters in Freiburg I’m Breisgau, Germany (2012).

Dr. Manbachi is an author on 25 peer-reviewed journal articles, 30+ conference proceedings, 10 invention disclosures/patent applications and a book entitled “Towards Ultrasound-guided Spinal Fusion Surgery.” His interdisciplinary research has been recognized by a number of awards, including University of Toronto’s 2015 Inventor of year award, and Ontario Brain Institute 2013 fellowship.

Dr. Manbachi has extensive teaching experience, particularly in the field of medical imaging and entrepreneurship both at Johns Hopkins and Toronto, for which he received the following two awards: University of Toronto’s Teaching Excellence award in 2014, as well as, Johns Hopkins University’s Whiting School of Engineering 2018 Robert B. Pond, Sr. Teaching Excellence Award.
