Background

About Me

I am a Senior AI Scientist at AstraZeneca (since 2022), where I apply cutting-edge machine learning to pharmaceutical research and development. Previously, I completed my postdoctoral research at KTH Royal Institute of Technology and earned my PhD in Computer Science with a Machine Learning specialization under the supervision of Prof. Montresor.

My expertise spans Graph Machine Learning, Deep Learning, MLOps, and Large Language Models . I'm particularly focused on bridging advanced ML research with real-world applications in drug discovery and healthcare.

Currently, my work focuses on productionizing AI systems at scale, combining deep learning innovations with robust MLOps practices to accelerate pharmaceutical innovation.
