Dr. Yaroslav O. Halchenko

Dr. Yaroslav O. Halchenko is a Research Professor in Dartmouth College’s Department of Psychological and Brain Sciences, where he leads the Center for Open Neuroscience. His work focuses on advancing open software, data, and community-driven standards to accelerate efficiency, reproducibility, and data sharing in neuroscience and beyond. He holds a Master’s in Optoelectronic Engineering (Vinnytsia National Technical University, Ukraine), a Master’s in Computer Science (University of New Mexico), and a Ph.D. in Computer Science (New Jersey Institute of Technology). Dr. Halchenko has led or co-developed several widely used research infrastructure projects, including PyMVPA, NeuroDebian, DataLad, and HeuDiConv/ReproIn. Together with Satrajit Ghosh (MIT), he co-leads the BRAIN Initiative–funded DANDI Archive, which now provides open access to more than 800 TB of neurophysiology data. He also contributes to the development and interoperability of other large-scale data repositories, including OpenNeuro and EMBER, helping ensure that data and tools flow across initiatives rather than remain siloed. A strong advocate for standards as the “common language” for scientists and computers, Dr. Halchenko plays an active role in the development and governance of major neuroscience standards, including BIDS, NWB, and HED.
