Hello! I’m Ivi, a 1st year PhD candidate at the Max Planck Institute for Software Systems, under the supervision of Dr. Manuel Gomez-Rodriguez. My research interests lie broadly in the area of Human-Centered Machine Learning. Currently, I am investigating how to evaluate and compare large language models based on human alignment.

Before joining MPI-SWS, I received my MEng in Electrical and Computer Engineering from the National Technical University of Athens, where I did my diploma thesis with Prof. Symeon Papavassiliou. During my undergraduate studies, I was fortunate to do a research internship at ETH under Dr. Fanny Yang, where I worked on high-dimensional active learning. I also interned at the National Observatory of Athens and contributed to the development of the Flash Detection Software.
