I joined this lab with no background in analog electronics. I now conduct event-camera research using dynamic vision sensors (DVS/EVS) to capture asynchronous visual data for high-speed computer vision experiments. I built and wired precision analog hardware — a constant-current infrared LED driver circuit (op-amp/MOSFET-based), photodiode-based optical feedback for closed-loop validation, Raspberry Pi GPIO control, PT4115 constant-current LED drivers, and synchronized camera trigger signals. I developed Python tools for programmable LED pulse generation with adjustable pulse width, frequency, and duty cycle, plus data-processing pipelines for trigger-window extraction, pulse-level event analysis, and quality filtering of noisy recordings. I built diagnostic visualizations — cumulative event curves, event-rate plots, and reconstructed event images — to validate recording quality and system behavior, learning analog circuit design and validation methodology in the process. I collaborate with a research team on neuromorphic vision, event-based sensing, and high-temporal-resolution visual data analysis.
