Physician. Entrepreneur. Clinical researcher.
For over two decades, Dr. Adam Broncel has been working at the intersection of neurology and biomedical innovation, turning scientific discoveries into solutions that improve patients’ lives.
With a medical degree, a Ph.D. in neuromodulation, and international research experience in the USA and Europe, he has dedicated much of his career to exploring the power of vagus nerve stimulation. His research has been published in leading journals (Brain Research, PLOS, Neuroscience) and presented at major neurological congresses, from Helsinki to Amsterdam.
As an entrepreneur, he co-founded Biomed Innovation and Poland Ventures, building ecosystems that help international startups thrive. He has scaled ventures across borders, secured EU grants, and co-invented patents in neuromodulation. He also advises global initiatives and has represented Poland at MIT and other leading U.S. innovation hubs.
At Cogniguard, Dr. Adam Broncel serves as Chief Medical Officer and board member, leading our Polish branch. He designed and oversaw preclinical studies and the very first proof-of-concept trials of the Vguard method — and is now spearheading upcoming multicenter clinical trials in Europe and the U.S. His role bridges science, clinical development, and investor engagement, all with a single purpose: to bring breakthrough therapies for Alzheimer’s and cognitive decline to patients.
What motivates him most?
“The opportunity to turn scientific innovation into real solutions for devastating conditions like Alzheimer’s. Knowing that our work can change patients’ lives gives me purpose every single day.”
One achievement he’s especially proud of:
Leading the first human trials of the Vguard method, witnessing years of research come to life in patients, and seeing early signs of positive impact on memory and cognition.
Outside the lab and boardroom, Dr. Broncel finds balance through sports. He trains intensively in CrossFit and rides over 3,000 km of MTB trails every year, a challenge that keeps him both physically sharp and mentally energized.
For him, innovation is more than research — it’s about creating healthier, longer, and more fulfilling lives.

🔬With nearly five decades dedicated to neuroscience, Prof. Jan Konopacki has shaped the field of neurobiology and neuropharmacology of brain oscillatory activity. Since earning his Ph.D. in 1981 and full professorship in 1998, he has supervised over 70 MSc theses, 8 PhD theses, and 4 habilitations, authored more than 100 scientific papers (PubMed: Jan Konopacki), and written the widely used academic handbook Physiology of Animals (2016).
For most of his career, Prof. Konopacki has been affiliated with the University of Łódź, where he also served as Head of the Department of Neurobiology. During his years at the University of Calgary in the late 1980s, he developed a pioneering in vitro technique for inducing and recording EEG theta oscillations in hippocampal slices — a breakthrough that fundamentally changed how researchers study brain activity in vitro.
At Cogniguard, Prof. Konopacki designed the project’s preclinical studies on laboratory animals and now serves as a scientific consultant and adviser to Dr. Adam Broncel.
What excites him most is seeing how decades of preclinical neuroscience research can now directly contribute to clinical studies for patients with dementia and Alzheimer’s disease.
His motivation? Curiosity and the belief that science should make a real difference in people’s lives.
Outside of research, Prof. Konopacki is known for his easygoing personality, good sense of humor, and a rather unique hobby: collecting antique padlocks and keys. Today, in retirement, he enjoys life close to nature with his wife, while still sharing his expertise to push forward innovations in neuroscience.
