I'm a second-year Ph.D. student at Columbia University. I am advised by Shree Nayar, and my work is generously funded by the NDSEG fellowship. Before my Ph.D., I worked with Aswin Sankaranarayanan at CMU.

Research

My research is in computational imaging. I am interested in vision systems that use an extremely small number of pixels. Previously, I have worked on structured light systems for 3D scanning and measuring fruit freshness.
Cricket: A Self-Powered Chirping Pixel
Shree K. Nayar, Jeremy Klotz, Nikhil Nanda, and Mikhail Fridberg
ACM Transactions on Graphics (SIGGRAPH), 2024
paper, supplemental, code

Cricket is a novel light sensor that can measure light without the use of a power supply or a battery.

Computational 3D Imaging with Position Sensors
Jeremy Klotz, Mohit Gupta, and Aswin C. Sankaranarayanan
ICCV, 2023 (Oral Presentation)
paper, supplemental, video, code

We introduce a low-bandwidth method for 3D scanning with position sensing diodes that is robust to global illumination.

Fine-Grain Prediction of Strawberry Freshness Using Subsurface Scattering
Jeremy Klotz, Vijay Rengarajan, and Aswin C. Sankaranarayanan
ICCV Workshop on Large-Scale Fine-Grained Food AnalysIs (LargeFineFoodAI), 2021
paper, video, code

We show subsurface scattering measurements are useful for predicting fruit freshness.
