Mesut SahinCurrent Position: Assoc. Prof. of Biomedical Engineering at New Jersey Institute of Technology

Mesut Sahin received his B.S. degree in Electrical Engineering from Istanbul Technical University in 1986, and M.S. and Ph.D. degrees in Biomedical Engineering from Case Western Reserve University in 1993 and 1998. He worked with Dr. Durand on a neural prosthesis for obstructive sleep apnea and he shares a patent with him and Dr. Haxhiu on closed loop control of hypoglossal nerve stimulations on demand. After receiving PhD, he continued his training as a postdoctoral research associate in the Neural Engineering Center at CWRU. His research interests moved to the central nervous system during post-doctoral studies and he conceived the idea of using the neural activity of descending tracts in the spinal cord as a form of spinal cord-computer interface. The project was funded by a post-doctoral fellowship from Christopher Reeve Paralysis Foundation in 1999. He joined Louisiana Tech University, Ruston, LA as an Assistant Professor of Biomedical Engineering in 2001, where he received a Whitaker Award to continue this work. In this first academic post, Sahin developed a new concept: "floating light activated micro-electrical stimulators (FLAMES) for wireless activation of the central nervous system." This project continues to be one of the major research interests in Sahin’s laboratory at New Jersey Institute of Technology, Newark, NJ with support from NIH and in collaboration with Optical Characterization and Nanophotonics Laboratory at Boston University. He has been on the faculty of Biomedical Engineering at NJIT since the Fall of 2005 with promotion to Associate Professor in 2009. For the past few years, his research interests have expanded to include recordings of multi-unit activities and local field potentials from the cerebellum using flexible multi-electrode arrays. He has authored more than 50 peer-reviewed publications. Mesut Sahin is an Associate Editor to IEEE Transactions on Biomedical Circuits and Systems and a Senior Member of IEEE/EMBS.

He holds M.S. and Ph.D. degrees both in Biomedical Engineering, and B.S. degrees in both Mathematics and Electrical Engineering.

"Looking back on my time at CWRU - I think the success of our program lies in much of what I learned as a graduate student. While I am not working with Maxwell's equations - I still apply the analytic process and critical thinking that I learned at ANCL to the design of solutions that meet critical health care needs."

 

Megan MoynahanMegan Moynahan

Megan Moynahan is the Network Leader for Cardiac Electrophysiology and Monitoring Devices at the Food and Drug Administration’s Center for Devices and Radiological Health (CDRH). Ms. Moynahan received a B.S. degree in biomedical engineering from Johns Hopkins University in 1986, and a M.S. degree in biomedical engineering from Case Western Reserve University in 1990. Between 1990 and 1996, Ms. Moynahan was a researcher at Shriners Hospital in Philadelphia, developing open loop electrical stimulation systems for children with spinal cord injury and cerebral palsy. She joined the Food and Drug Administration in 1996 as a pre-market reviewer for neurological and cardiovascular devices.

In 2001, Ms. Moynahan became the chief of the Pacing, Defibrillators and Leads branch, overseeing the review teams responsible for approving the first cardiac resynchronization devices, the first over-the-counter automatic external defibrillator, and the expansion of implantable cardioverter defibrillators (ICDs) into the lower risk (“MADIT II”) population. In the wake of the Guidant ICD recalls of 2005-2006, Ms. Moynahan pulled the disparate CDRH groups together to develop a more cohesive approach to regulating pacemakers and defibrillators. The success of that model became the blueprint for a restructuring of the entire Center into a matrix organization in 2008, at which time Ms. Moynahan became the Network Leader for Cardiac Electrophysiology and Monitoring Devices. This role allows her to integrate the perspectives of the total product life cycle of these devices, assuring coordination among the premarket, surveillance, enforcement, research and communication efforts around the Center.

Ms. Moynahan is an internationally recognized advocate for the premarket and postmarket safety of pacemaker and defibrillator devices. She is regularly invited to speak on regulatory and scientific aspects of these devices. In recent years, Ms. Moynahan’s work with the Heart Rhythm Society, American Heart Association, AdvaMed, and other national groups has enabled her to influence public policy outside of the FDA. Working with the National Cardiovascular Data Registry, she was instrumental in influencing the reporting structure that would allow collection of information about implanted ICD leads in the National ICD Registry. In 2008, she organized a public meeting, “FDA Workshop: Best Practices for Pacemaker and ICD Lead Postmarket Surveillance,” bringing together over 100 national and international electrophysiologists, industry representatives, FDA regulators, and press.

Within FDA’s Center for Devices, Ms. Moynahan helps the organization envision and put into practice broad program initiatives, such as the Signal Escalation Business Process. This program allows staff in CDRH to raise awareness of problems they see with regulated medical devices so that action can be taken to mitigate risks to patients. Since it began less than a year ago, the program has processed more than 350 signals, with some resulting in product recalls and safety notifications by FDA.

Ms. Moynahan currently serves as vice chair of CWRU’s Biomedical Engineering Advisory Board.

Cameron McIntyreDr. Cameron McIntyre

I was an undergrad student in ANCL from 95-97 and a grad student from 97-01. My advisor was Warren Grill.

Short Bio: Cameron McIntyre was born in Marietta Ohio and received his B.S. and Ph.D. in Biomedical Engineering from Case Western Reserve University in 1997 and 2001, respectively. His doctoral research focused on the biophysics of the interaction between electric fields and neurons. From 2001 to 2003, Dr. McIntyre performed post-doctoral training at Johns Hopkins University and Emory University where he studied deep brain stimulation (DBS) for the treatment of Parkinson's disease. In 2003 he joined the faculty at the Cleveland Clinic Foundation where he is currently appointed as Associate Staff in the Department of Biomedical Engineering and holds adjunct professorships at Case Western Reserve University. The McIntyre laboratory is internationally recognized for its contributions to the field of DBS in both scientific discovery and the development of novel clinical technology. Current work is focused on characterizing the neurophysiological effects of DBS in human patients with movement or psychiatric disorders, and this work is supported by numerous grants from the National Institutes of Health. The fundamental goal of the research program is to use growing knowledge on the therapeutic mechanisms of DBS to better engineer the next generation of DBS medical devices. In turn, the laboratory generates numerous patents each year, many of which are associated with the Cleveland Clinic spin off company IntElect Medical Inc., which Dr. McIntyre co-founded in 2005.
