CEN’s Introduction to Intraoperative Neurophysiologic Monitoring program

Founded by Dr. T.V. Seshan, a Physical Medicine and Rehabilitation (PM&R) physician and pioneer in the field of IONM, CEN is committed to the training and placement of skilled and insightful surgical neurophysiologists.

CEN faculty advisors are senior clinicians with extensive experience in the most complex brain, spine, vascular and peripheral nerve surgeries. Each advisor is committed to providing students with the knowledge and tools necessary for success as an IONM technologist.


When a patient undergoes surgery, they cannot speak for themselves. No one knew this truth better than pioneering IONM physician, Dr. Thirumoorthi Seshan. Intraoperative Neurophysiologic Monitoring (IONM) was not only his expertise but also his passion. The Center for Electroneurodiagnostics (CEN) began from his vision of a healthier world — a place where people are empowered to speak up for those who cannot speak for themselves.

In the early 1980s, Dr. Seshan began utilizing methods to assist several prominent surgeons with pediatric scoliosis corrections. Recognizing the importance of IONM and its vital role in patient safety, Dr. Seshan saw tremendous value in sharing his knowledge with others. Because of this, he founded an IONM training program that would eventually become known as the Center for Electroneurodiagnostics. The program he birthed empowers individuals to keep patients safe from surgical injury and able to maintain their livelihood.

Dr. Seshan’s ultimate goal was to create a comprehensive educational program that encompassed all of the ideals necessary to create highly skilled surgical neurophysiologists. Today, CEN produces hundreds of qualified and employable clinicians each year. At the time of his passing, Dr. Seshan alone had monitored thousands of cases. Now, because of his vision, CEN graduates will go on to monitor and protect thousands more.

Dr. Christopher Pace, Ph.D., CNIM

Dr. Christopher Pace is chief clinical officer at Neuro Alert. He received his Ph.D. in neuroscience from Albany Medical College in 2001 and his “Certification in Neurophysiologic Intraoperative Monitoring” (CNIM) from the American Board of Registered Electroencephalographic and Evoked Potential Technologists (ABRET) in 2006. He previously served as vice president of clinical service programs for the development of surgical neurophysiologists at several institutions as well as the director of neurophysiology at The Butterfly Foundation, a nonprofit organization that offers spine surgery to patients in developing countries.

Rose Auerbach, B.S., CNIM

Rose Auerbach received her B.S. in neuroscience from Brandeis University. She continued her post-graduate studies in biomedical sciences at the Wadsworth Center at University at Albany, State University of New York. Her extensive knowledge of IONM comes from having monitored nearly 1,000 orthopedic and neurological surgeries — from the routine to the most complex. Rose’s gift for teaching, coupled with her keen understanding of surgical neurophysiology, made her instrumental in expanding the CEN education program. She looks forward to imparting her knowledge and preparing you to become a leader in this quickly growing healthcare field.
