Dr. Manbachi is an Assistant Professor of Neurosurgery, Biomedical Engineering, Mechanical Engineering, Electrical and Computer Engineering at Johns Hopkins University. His research interests include applications of sound and ultrasound to various neurosurgical procedures. These applications include imaging the spine and brain, detection of foreign body objects, remote ablation of brain tumors, monitoring of blood flow and tissue perfusion, as well as other upcoming interesting applications such as neuromodulation and drug delivery. His pedagogical activities has included teaching engineering design, innovation, translation, and entrepreneurship as well as close collaboration with clinical experts in Surgery and Radiology at Johns Hopkins. 

His doctoral work embodied the development of ultrasound-guided spine surgery. He obtained his PhD from the University of Toronto, under the supervision of Dr. Richard S.C. Cobbold. Prior to joining Johns Hopkins, he was a postdoctoral fellow at Harvard-MIT Division of Health Sciences and Technology (2015-16) and the founder and CEO of Spinesonics Medical (2012–2015), a spinoff from his doctoral studies.

Amir is an author on >30 peer-reviewed journal articles, > 30 conference proceedings, > 10 invention disclosures / patent applications, and a book entitled “Towards Ultrasound-guided Spinal Fusion Surgery.” He has mentored 150+ students, has so far been raised $15M of funding and his interdisciplinary research has been recognized by a number of awards, including the University of Toronto’s 2015 Inventor of Year award, Ontario Brain Institute 2013 fellowship, Maryland Innovation Initiative, and Johns Hopkins Institute for Clinical and Translational Research's Career Development Award.

Dr. Manbachi has extensive teaching experience, particularly in the field of engineering design, medical imaging, and entrepreneurship (both at Hopkins and Toronto), for which he received the University of Toronto’s Teaching Excellence award in 2014, as well as Johns Hopkins University career centre's award nomination for students' "Career Champion" (2018) and finally Johns Hopkins University Whiting School of Engineering's Robert B. Pond Sr. Excellence in Teaching Excellence Award (2018). more

Research Summary

Personal Statement

My long-term goal is to initiate and lead meaningful research projects that can routinely generate clinical translation and commercial enterprises, hence benefiting medicine and society, and I currently do this through nurturing and mentoring the next generation of Biomedical Engineers (164 trainees to date) at Johns Hopkins while collaborating with Hopkins neurosurgeons on their ideas. What keeps me awake in the middle of the night is the anticipation of the next great scientific idea, and the next collaboration with clinicians, leading to a new generation of inventions, prototype developments, industrial partnerships, FDA approvals and market sales, thereby saving patients’ lives on a global caliber, in addition to creating jobs, thereby helping the local community. Biomedical engineers are poised to make unparalleled impact and save lives by inventing devices that can help millions of patients worldwide, and I am committed to fulfilling that role! My interests and expertise are in the following areas: physics of acoustics, as well as design and fabrication of novel image-guided interventions (primarily ultrasound imaging, and most recently therapeutic ultrasound), with a passion for clinical translation and quality assurance for patient safety. My clinical research interests and involvement since my Ph.D. have been primarily on minimally invasive approaches in the areas of neurosurgery, specifically in brain and spine. Having founded a company based on my Ph.D. studies (Spinesonics Medical Inc.), currently leading another entrepreneurial initiative to develop a focused ultrasound device (for which we have already raised over $250K), and closely mentoring close to 40 design projects in affiliation with the Center for Bioengineering Innovation and Design (CBID) and the JHU BME undergraduate design program, our department's remarkable record for clinically driven research and innovation deeply resonate with me. In particular, this department offers exceptional access to medical and engineering resources, and I have fully leveraged that in my collaborations with the Departments of Surgery and Radiology, and the Armstrong Institute for Patient Safety.

Mission Statement

(1) To bring novel medical devices into the neurosurgical world by exploring innovative designs; (2) scholarship through communicating the findings to the world; and (3) training the next generation of biomedical engineers, passionate about changing the paradigm of brain and spinal cord injury treatments.
