About Me
As a dedicated neurologist with a specialization in general and vascular neurology, I primarily treat patients suffering from stroke. Due to the preventable nature of stroke, I strive to focus on the stroke etiology. My work includes participation in innovative clinical trials primarily on stroke identification and later rehabilitation, allowing me to bring the latest treatments to my patients. My decision to pursue neurology was driven by a fascination with the intricacies of the human brain and a desire to provide tangible relief to those affected by neurological disorders. Outside of my professional life, I enjoy people and nature photography.

Clinical Focus and Research
My research concentrates on the development of imaging biomarkers for post-stroke vision restoration. I'm actively exploring non-invasive techniques such as transcranial direct current stimulation and other neuromodulation techniques with the goal of enhancing vision recovery post-stroke.
