Data, network and computational social scientist, but mainly ultra-cyclist wannabe.

Alessandro Galeazzi

Tenure-Track Assistant Professor, Department of Mathematics, University of Padova

I study how the interactions between people, content and algorithmic systems shape collective outcomes in digital societies. I read society through the digital traces it leaves behind: online debates, news, and cultural products such as music and images.

My approach is computational and quantitative, with a social science perspective. I turn digital traces into datasets and analyse them with network analysis, natural language processing, machine learning and statistical inference, to measure how opinions fragment, how algorithms change what we see, and how culture evolves.

My research, as a network

Every node is a paper, coloured by theme. Drag the nodes around, or pick a theme to highlight it.

Node size ∝ citations · hollow nodes are preprints · solid lines join papers of the same theme by shared co-authors · dashed lines join themes

Teaching

I teach programming and computer systems, from Python for biologists to operating systems and computer architecture, and data science for the social world at master's and Ph.D. level.

Public engagement

Talks for the public at Science4All and DataBeers, research covered by the BBC, Science News, ANSA and Nature Italy, and studies that reached the G7 and Ofcom.

Off the desk

I ride almost every day. The bike is my favourite way to get to work in Padova, how I train, and, when the distance makes sense, how I get to conferences. I love long days in the saddle: mountain passes in the Dolomites, ultra-distance events and multi-day trips across Europe. But sometimes I take the car too.

The cycling page maps every ride I have recorded since 2021 and estimates the CO₂ saved by commuting and riding to conferences instead of driving, flying or taking the train.

Collaborate

Working on online polarization, platform algorithms, or cultural evolution?

I am always happy to hear about research ideas, data and projects in computational social science. Write to me with a few lines on what you have in mind.

Ride

Fancy a ride around Venice, Padova or in the Dolomites?

Long days in the saddle, a climb against the clock or a ride to the next conference: if you are around and want company, send me an email.
