I am a neurobiologist and clinical researcher specialized in nutrition, nutritional therapy and brain research. Previously I have been affiliated with the National Institute of Clinical Neuroscience, Budapest and the Neurological Department, University of Pécs, Hungary and have been involved in research related to epilepsy and sleep, elecroencephalograpy, vitamin D and brain MRI. Since 2013 I am the CEO of ICMNI - Paleomedicina. We have developed the paleolithic ketogenic diet (PKD) and have been using it in our clinical practice during the last 10 years in the treatment of diabetes, autoimmune diseases and cancer. It is clear that the method we developed is of superior effectivity as compared to standard medicinal therapies. Our patients are not just "treated" but literally cured if the principles of the method are properly applied. Our team is also involved in publishing medical cases and research data in academic journals. We distance ourselves from non-scientific approaches and naturopathy. Our approach conforms major criteria of science: replicability, cognizability and biological plausibility.

SCIENCE METRICS

In international academic journals, I have published 40 research articles with more than 1100 citations.
