M.D., Ph.D.,MPH, M.S., BCN

Leon is an associate Research Director at the Neuromodulation Center, Spaulding Rehabilitation Hospital which is a Division of Harvard Medical School. Dr. Morales works with non-invasive brain stimulation to promote recovery of function in neurological patients and children with disabilities. He has published numerous articles in professional journals and lectures internationally.

His Interest is to investigate the mechanisms and effects of neuromodulation by means of non-invasive brain stimulation, to promote recovery by facilitating processes of plasticity and learning in patients with neurological conditions. IHis focus is research in the development of rehabilitative protocols using different neuromodulatory techniques, such as Transcranial Direct Current Stimulation (tDCS), Transcranial Magnetic Stimulation (TMS), and Transcranial Pulsed Current Stimulation (tPCS), and Transcranial Alternate Current Stimulation (tACS) in combination with pharmacological interventions to promote and restore cognitive functioning and overcome disability. After finishing my masters in neuropsychology, He spent 5 years working as clinician in neurological rehabilitation, where he evaluated and treated patients with neurological and cognitive disabilities. It was clear for him that these patients lacked any real therapeutic option, for this reason he decided to start at the same time my doctoral degree so I could understand better the mechanisms associated with plasticity in severe brain damage, and how to use and apply different methods in order to reach this premise.

He was trained in clinical research and neuromodulation as research Fellow in the Neuromodulation Laboratory, Spaulding Rehabilitation Hospital where he completed his doctoral research. He also was a Fellow in the Neurobiology Department of Boston Children’s Hospital, where my work focused on translational research in animal models of brain stimulation and post traumatic damage, this fellowship was developed under the mentorship of Dr. Alexander Rotenberg.

Angelika Sadar


Angelika is a psychologist that has been in private practice since 1987. Once introduced to neurofeedback, she found the knowledge of the brain provided a tool to help patients change in a way that had often taken years with psychotherapy alone. As she incorporated neurofeedback into my practice, the desire to learn about this method was insatiable and took her to Switzerland, where she learned of the HBI database. With the research behind this method and the introduction of event related potentials as a means of understanding brains, it seemed that neurofeedback and then biofeedback, were to become integral tools in my work. Since 2006, She has treated thousands of patients and have presented at numerous events to train other clinicians in this method. She has been grateful to learn from leaders in the field including Jay Gunkelman, who has kindly devoted hundreds of hours to teach me.

It has been her pleasure to be the executive director of the Northeast Region Biofeedback Society for the past 5 years and to consult with numerous clinicians who embarked on developing their assessment and neurofeedback skills. Presently, she is interested in utilizing the latest research to make objective assessments to help people improve their lives. In partnering with HBI, she is eager to help other clinicians have access to assessments that are based on quantitative comparisons of measurements of the EEG and ERPs.

Mitchell Sadar


Mitchell is a clinical psychologist who has been practicing neurofeedback since the late nineties. As he integrated neurofeedback into his practice he became aware of the utility of an objective brainwave assessment in addition to a thorough clinical history. At that time, the cost of a qEEG was prohibitive to most of the people seeking help at our clinic, so he developed a version of the Mini-Q based on the work of Paul Swingle, Ph.D. This was used as a part of our evaluation process for several years. Once the cost of qEEGs became more affordable, their use became routine in our clinic and have been used to develop hundreds of protocols for patients of all ages with various presenting complaints ranging from ADHD to autism, anxiety/depression, migraines, TBI, peak performance, etc. Several years ago I was introduced to the value of assessing event related potentials (ERPs) through Andreas Muller, Ph.D., and Yuri Kropotov and added this measure to our clinical evaluation process.

He has sought ongoing training from these individuals as well as Jay Gunkleman, and see ERPs as a key component in the future of our field and acceptance of our field by the medical community. As President of the Board of the Northeast Region Biofeedback Society for the past 4 years he has had the opportunity to interact with a wide range of practitioners. I have learned from them and become aware of what might help them to increase the treatment successes they are already having.

His interest is in disseminating the benefits of qEEG, ERPs, neurofeedback and biofeedback to mental health and health providers, having such people have access to understandable and practical assessment results and recommendations.

Andreas Müller

Andreas Müller


Andreas is an expert in the study of the human brain. For the past 17 years he has been the CEO of the Bündner Brain and Trauma Foundation has been exploring the links between biology and mental disorders – for example in ADHD. Previously the head of the School Psychology Service Graubünden together with the world-famous Russian neurophysiologist Yuri Kropotov, in 2003 he initiated his first research project: recordings of brainwaves of 250 healthy children and adolescents to create a database. As early as 2004, the database was expanded by 540 adults. Together with people from Norway and Russia, the people of Grisons formed the basis of an index database on the human brain. Müller has been CEO of the Brain and Trauma Foundation in Grisons since 2006.

Comparatively new to Müller’s research is that mental illness can be objectively detected by quantitative comparisons of measurements with the so-called EEG. Müller likes to make use of a comparison from another area of ​​medicine: “Psychiatry is today at the point where surgery in the invention of the X-ray apparatus was more than 100 years ago.” Muller and his colleagues have studied the biological causes of Attention-Deficit / Hyperactivity Disorder (ADHD) with particular interest. According to Müller, this research focus has come from everyday practice as a child and adolescent psychologist. “Our research must benefit patients exclusively.” ADHD visible in black on white, Muller has since lectured internationally on this topic in South Korea, United States, Israel, Brazil and more. For the method, among other things, the patients have to analyze images on the PC for 22 minutes and click on the correct sequence with a computer mouse. “Persons affected by ADHD are very hard-eyed anyway,” says Müller. Because the brain waves were measured during the test, the researchers could also objectively detect the disorder – black and white. The method enables a virtually unequivocal diagnosis of ADHD, says Müller. “Thanks to the measurements, we also know what we need to do in therapy.” In addition to detailed instructions for the procedure in non-drug therapies, he mentions the great advantages of prescribing drugs such as Ritalin. “In conventional diagnoses, around two-thirds of patients respond to the medication. The method provides virtually 100% responder quality. This same method has been expanded to understanding chronic pain, anxiety, Parkinson’s disease, and more.
