About Me

I am a PhD student at the Visual Recognition Group, Czech Technical University, advised by Lukas Neumann.

My research focuses on Weakly-Supervised 3D Detection for autonomous driving. I aim to reduce the reliance on expensive 3D annotations by leveraging temporal consistency and 2D cues from off-the-shelf vision models.

Previously, I completed my MSc with honours, receiving the Dean's Award for my thesis on 3D object detection.
