I turn raw imagery into decisions. I build deep-learning and computer-vision systems for terabyte-scale sensor data — from foundation-model segmentation to multimodal and temporal modeling — scaling experiments on HPC and turning them into reproducible pipelines. I’m looking for roles where real-world data, computer vision, and ambitious model building meet.

01 — About

I’m a Ph.D. candidate at the University of Florida, graduating in December 2026, building applied AI and computer-vision systems for large-scale, real-world sensor data — terabytes of aerial imagery, imperfect labels, shifting seasons, and models that have to hold up outside the lab.

I've worked hands-on with the whole sensing stack: RGB, multispectral, thermal, and hyperspectral cameras, flown on UAV platforms from DJI to Freefly and Inspired Flight — owning everything from sensor integration and flight operations to data processing, model training, and validated predictions people act on.

I use foundation models such as SAM and Depth Anything, object detection, multimodal fusion, and temporal models — wrapped in automated, reproducible pipelines and trained on UF’s HiPerGator HPC (SLURM).

I’m most energized by messy-data problems that demand both research judgment and engineering discipline. That opens the door to applied ML, computer vision, research engineering, multimodal AI, and foundation-model teams — including opportunities to grow toward larger-scale and world-model research.

Multimodal, Explainable Framework for Crop Nutrient Prediction

A multimodal ML framework that combines UAV imagery, phenotypic traits, management records, and environmental time series to predict plant nutrient status. I built and evaluated models spanning classical ML, deep image fusion, and temporal sequence learning, then tested the final pipeline on a fully independent growing season. The work revealed where the strongest predictive signal actually comes from and how well the system holds up across seasons.
