Hello, I am Georgios, welcome to my personal website!

I am an [Eric and Wendy Schmidt AI in Science Postdoctoral Fellow](https://aiscience.uchicago.edu/fellows/) in the [Department of Astronomy and Astrophysics](https://astrophysics.uchicago.edu/people/profile/georgios-valogiannis/) and the [Kavli Institute for Cosmological Physics](https://kavlicosmo.uchicago.edu/people/profile/georgios-valogiannis/) at the University of Chicago. Previously I was a postdoctoral research fellow in the [Department of Physics](https://www.physics.harvard.edu/%20) at Harvard University, working with Prof. [Cora Dvorkin](http://dvorkin.physics.harvard.edu/Home.html), and I received my PhD in [Astronomy](https://astro.cornell.edu/) from Cornell University, under the supervision of Prof. [Rachel Bean](https://blogs.cornell.edu/rachelbean/).

I am a **cosmologist** broadly interested in testing **fundamental physics with the large-scale structure (LSS) of the Universe**, focusing on the nature of **dark energy, dark matter, and gravity**. My research combines **analytical modeling, high-performance simulations, and machine learning–based inference** to extract the full cosmological information from Stage-IV cosmic surveys.

I currently serve as **co-lead of the Modeling and Combined Probes (MCP) working group** within the [**LSST Dark Energy Science Collaboration**](https://lsstdesc.org/) **(DESC)** and **co-lead of the Alternative Clustering Methods topical group** in [**DESI**](https://www.desi.lbl.gov/the-desi-survey/). I am also a member of the [**NSF–Simons AI Institute for the Sky (SkAI)**](https://skai-institute.org/), where I work on applying AI-driven field-level inference to cosmological data.

If you would like to find out more about my research, please check the relevant section of this page, as well as my most recent CV attached below.

You can find my full publication record in the [ArXiv](https://arxiv.org/search/?query=Valogiannis&searchtype=all&abstracts=show&order=-announced_date_first&size=50), [Inspire-HEP](https://inspirehep.net/authors/1890484?ui-citation-summary=true) and [ADS](https://ui.adsabs.harvard.edu/search/p_=0&q=author:%22Valogiannis,%20Georgios%22&sort=date%20desc,%20bibcode%20desc) databases.
