What I'm looking for

I seek research-oriented roles applying deep learning to physics or materials science, with opportunities for dataset creation, model development, and collaboration in academic or industry labs.

I am a research-focused machine learning engineer who develops deep learning models—especially convolutional and graph neural networks—to solve problems in physics, materials science and fusion diagnostics. My work includes automating tip-enhanced Raman spectroscopy, building custom datasets and fine-tuning detection and tracking models such as YOLO to improve PSNR and SSIM on experimental video data.

I hold an Erasmus Mundus master’s degree in Photonics for Security, Reliability and Safety and advanced AI coursework at Aalto University, and I have contributed to research at EPFL, Montanuniversität Leoben and the University of Cassino. I bring hands-on experience in data preprocessing, self-supervised learning, generative models, reinforcement learning simulations, and scientific computing with Python, PyTorch, CUDA and MPI.
