Oleg Solopchuk

MD, PhD Student

oleg solopchuk 140x180Oleg joined the CoActions lab as a PhD student in July 2014. Having worked on sequence learning and chunking and chunking during his first 2 years in the lab, his current research primarily focuses on the computational mechanisms of mental effort. He is interested in machine learning, neuroimaging and neuromodulation.
