Aditya Gulati
Postdoctoral Researcher · ELLIS Alicante

I study human-AI interaction — specifically, how people form trust, calibrate reliance, and apply cognitive heuristics when working with AI systems. My work sits at the intersection of AI, cognitive science, experimental psychology, and human-computer interaction.

My PhD at ELLIS Alicante, advised by Nuria Oliver, Bruno Lepri, and Miguel Ángel Lozano, examined how congnitive biases, particularly the attractiveness halo effect, shape human judgment and propagate into AI systems. I combine large-scale crowdsourced experiments (N = 2,700+) with computational AI evaluation to produce evidence that is both statistically rigorous and ecologically valid.

Previously, I was a visiting researcher at Fondazione Bruno Kessler (Trento) and a research intern at the Dynamic Decision Making Lab at Carnegie Mellon University.
