  • 2020 - 2022

  • R&D engineer collaborating with healthcare partners for medical device translation with therapeutic aim to central nervous system disorders (epilepsy, aphasia). Maintained quality systems to meet FDA regulations. • Investigate macro and micro scale electrodes for medical device development. Design and fabricate micro and macro sensors for electrophysiology data collection (128 channels) in-vivo. Verify the prototype by electrochemistry (Autolab).• Creative solutions and product design in Fusion 360, rapid prototyping (3D printing) to assist hardware automation.• Automated a system to synchronize mechanical stimulation with high speed imaging. Perform image processing to observe 0.5% change in brain hemodynamic physiology and detect blood vessels before device implantation. • Assemble mechanical stimulation setup and low noise (~5uV RMS) Intan data acquisition system, collect neural data (LFP, ECoG).• Perform signal processing to extract fundamental frequency bands from LFP. Use the extracted bands as feature and implement machine learning algorithms to train and test classification models, predicting a mechanical stimulation with 89% accuracy. • Innovate techniques toward device manufacturing, currently being prepared for intellectual property (patent) submission.• Lead surgeon for preclinical testing ( rodent neurosurgery). Execute histology (Cytochrome oxidase) to identify barrel locations in rat brain tissue sections.
