6-month research internship on contrastive learning for images. Here, my work has focused on using foundation models (like SAM) to select better views for contrastive learning (which is usually done randomly). Accepted at NeurIPS 2023 workshop [1]. I also invented a method for batch image annotation (pending patent) [2].

Research project on 3D reconstruction with Neural Radiance Fields (NeRFs), which we extended to be able to generate any wavelength (not just RGB). This enables all new use cases in biology and recycling, where different plants or materials exhibit different properties depending on the wavelength they are viewed from. Under review at 3DV 2025[4].

Developed a solution fusing camera, LiDAR and IMU for projecting landmarks from 2D maps to the vehicle’s camera frame, enabling to get high-quality-pseudo labeled training data for object detection models.

The method was accepted at IEEE IV 2023 [5], the most prestigious conference on intelligent vehicles.

6 months research internship on Deep Unsupervised Anomaly Detection. Goal: Improve defect detection on industrial parts.

• Co-authored a heuristic to remove defective parts in a fully unlabelled dataset with 90+ AUC.
• Fine-tuned pre-trained networks with synthetic defects to improve defect detection AUC from 91.6 to 96.1 points.
