Aravinthan Samuel

Aravinthan Samuel is a Professor of Physics at Harvard University leading the Samuel Lab, where he investigates neural circuit mechanisms underlying behavior in model organisms like C. elegans and Drosophila larvae. His research integrates biophysics, neuroscience, and computational approaches to decode how sensory inputs transform into behavioral outputs through quantifiable neural algorithms.

His work centers on neural circuits, sensory processing, and behavioral plasticity using advanced microscopy and connectomics. The lab employs C. elegans and fruit fly larvae to map entire neural circuits at synaptic resolution, focusing on chemotaxis and thermotaxis behaviors. Recent innovations include machine learning applications for neuron tracking (e.g., Membrain, SmartEM) and novel microscopy techniques for recording neural activity in freely moving animals, revealing how neural ensembles encode sensory information and generate behavioral motifs.

Publications from 2023-2025 demonstrate a strong trend toward machine learning-driven neuroscience, with emphasis on automated connectome segmentation, behavioral plasticity mechanisms, and multi-neuronal imaging. Key themes include combinatorial odor coding, context-dependent mating behaviors, and hardware/software co-design for microscopy, spanning biophysics, computational neuroscience, and optical engineering disciplines.
