Yohan John is a Research Assistant Professor in the Neural Systems Laboratory at Sargent College, Boston University, specializing in computational and systems neuroscience. He holds a PhD from Boston University’s Department of Cognitive and Neural Systems, where he studied under Profs. Dan Bullock and Frank Guenther, focusing on reinforcement learning and timing in the basal ganglia. His postdoctoral work with Prof. Helen Barbas explored cognitive-emotional interactions using computational modeling. Yohan’s research centers on dynamical systems theory as a unifying framework for understanding brain dynamics and psychiatric disorders, particularly how disruptions in neural networks manifest as symptoms.

- BSc in Physics, St Stephen's College, Delhi (2004)
- MSc in Physics, Indian Institute of Technology Bombay (2006)
- PhD in Cognitive and Neural Systems, Boston University (2011)
His research interests span dynamical systems theory, computational neuroscience, cognitive-emotional interactions, and psychiatric disorder modeling. He is particularly interested in how brain networks generate stable cognitive and behavioral states (attractors) and how their pathology leads to mental illness. He also investigates broader philosophical and epistemological questions in science, especially the role of metaphor, naming, and boundaries in cognition.
Yohan’s recent publications and essays reflect a strong interdisciplinary approach, bridging neuroscience, philosophy, AI, and science communication. His work on semiotic ghosts in LLMs, the power of naming, and visual metaphors in science demonstrates his interest in the intersection of cognition, language, and computation. These writings reveal a consistent theme: understanding complex systems through dynamic, emergent, and metaphorical lenses.

Yohan is actively involved in science outreach, writing for the public on Quora (where he is a top writer in neuroscience) and co-organizing the NeuroLogos YouTube channel, which discusses recent developments in cognitive neuroscience. He has also led discussion groups on dynamical systems, neural representations, and computational theories of mind. While no formal students or grants are listed, his advisory or mentoring roles may exist informally through these educational initiatives.
