Behind the Paper: Uncertainties and Differentiable Imaging
After completing my BS in computer science, I transitioned to optical engineering for graduate school—but my body seemed to rebel against the very environment I'd chosen. Every time I entered the lab, waves of nausea, headaches, and dizziness would overwhelm me. After months of this mysterious suffering, I reached a dramatic conclusion: I must be allergic to lasers. -
