Hello There, I am John
👋 Welcome! I’m a dynamic researcher 🧠, inventive game developer 🎮, and a passionate pianist 🎹 with an unwavering love for Chopin 🎼.
Checkout my projects🔬, publications📝, and music🎵.
I completed a double major in Computer Science and Electrical & Computer Engineering (Mechanical Engineering minor) at Worcester Polytechnic Institute, where I was supervised by Prof. Erin Solovey and Prof. Kaveh Pahlavan. I earned my Master’s degree in Computer Science at Columbia University under the guidance of Prof. Steven K. Feiner, Prof. Paul Sajda, and Prof. Kaveri Thakoor. My research focuses on multi-modal sensor fusion and Clinical AI.
I specialized in developing multimodal sensor fusion systems for virtual and augmented reality (VR/AR), integrating physiological data to study decision-making and navigation in real-world scenarios. My vision includes helping those with neurodegenerative disorders by designing BCIs that improve daily life, combining technology with a commitment to enhancing well-being. Currently, I am a Research Assistant at the Martinos Center for Biomedical Imaging, Harvard Medical School, where I am working on closed-loop neuro-stimulation.
Research Interests: Sensor Fusion, Embodied AI, Computer Vision, Wireless Sensing, Virtual Reality (VR), Augmented Reality (AR), Neuroimaging (EEG, fNIRS, fMRI), Brain Stimulation (TMS, tDCS), Signal Processing, Deep Learning, Machine Learning,
Other Interests: Piano, Soccer, Chess
