“It takes all kinds of people to make the world beautiful. You can do it too.”

— Sadhguru

Hi, I’m Klea Ziu, a final-year PhD student in machine learning at MBZUAI, advised by Martin Takac. I develop reliable and data-efficient ML methods for scientific discovery, with a focus on chemistry, catalysis, and sustainable technologies.

My work sits at the intersection of machine learning and the chemical sciences. I am especially interested in models that respect scientific structure and remain useful when experimental data are limited, noisy, or expensive. Recent directions include Neural ODEs for reaction kinetics, graph neural networks for catalyst design, and ML prediction of density of states (DOS).
