Emre Onur Kahya

Professor of Physics · Istanbul Technical University

I study quantum fields, gravitation and cosmology — and, increasingly, what learning machines compute on the inside.

IIFields & the early universe

Quantum fields on a curved, expanding stage

How does a quantum field behave when spacetime itself is dynamical? I compute quantum — including quantum-gravitational — corrections to fields during inflation, and work on observational tests that can tell gravitational theories apart.

IIILearning from physical data

When measurements become representations

Machine learning helps physics when the data, the baseline and the evaluation reflect the scientific question — from classifying multiband light curves to identifying electrons in ATLAS data and forecasting satellite conjunction risk.

IVInside the model

From what a model predicts to how it computes

My current research direction is mechanistic interpretability: which internal representations a model forms, and which of them it actually uses. Interventions such as ablation and activation patching turn pictures into testable causal hypotheses — when baselines and controls are taken seriously.

Schematic illustration — no real model is analysed here. This is an ongoing research direction, not an established result.

VPhysics, out loud

Waves that reach people

Since 2021 I have talked about physics, the history of science and artificial intelligence on Teke Tek Bilim — in long conversations with Fatih Altaylı, Emrah Safa Gürkan and fellow scientists, and in my own series, Bilim Ekstra.

About

A physicist, a teacher, a communicator

I study quantum fields, gravitation and cosmology, and develop machine-learning approaches to physical data. My current research direction asks how the internal mechanisms of learned models can be understood and tested. I also talk about physics and artificial intelligence for a broad Turkish-speaking audience.

Recognitions include the Turkish Academy of Sciences Outstanding Young Scientist Award (GEBİP, 2015), the TÜBİTAK Science Incentive Award (2016) and the Mustafa Parlar Research Incentive Award (2017).
