About Me

I’m a computational social scientist, currently working as an Assistant Professor at University of Novi Sad, Faculty of Philosophy. I completed my sociology PhD in 2019 and my main research interests are centered around applying and developing statistical and computational methods.
I’m also as a member of Serbian European Social Survey team.
My Erdős number is 4 (A. Tomašević – M. Mitrović Danuklov – G. Caldarelli – B. Bollobás – P. Erdős).
Fulbright grant
In the Fall semester of 2023, I will be a Fulbright Visiting Scholar at the University of Virginia. During my visit, I will be working closely with Hudson Golino in the Department of Psychology.
I’m also looking forward to meeting, collaborating, and discussing ideas about computational social science, network science, or complex systems with people from across disciplines. I will have plenty of time, so feel free to write an email and let’s arrange a meeting :)

Understanding how different factors influence their sustainability is of crucial importance. We explore the role of the social network structure and social trust in their sustainability. We analyze the early evolution of social networks in four pairs of active and closed Stack Exchange communities on topics of physics, astronomy, economics, and literature and use a dynamical reputation model to quantify the evolution of social trust in them. In addition, we study the evolution of two active communities on mathematics topics and two closed communities about startups and compare them with our main results. Active communities have higher local cohesiveness and develop stable, better-connected, trustworthy cores. The early emergence of a stable and trustworthy core may be crucial for sustainable knowledge-sharing communities.}, copyright = {2023 The Author(s)} }

Software
I’m a Linux 🐧 geek, so naturally I support FOSS in everything I do.
I enjoy coding in R, Python and Julia. I don’t enjoy JavaScript.
Whenever possible I prefer plain text (txt
, md
, tex
) to alternatives. I like to own my files and don’t depend on proprietary software to read them in 5, 10 years or more. I’m also a fan of single text file productivty, you can check out my VSCode extension Working Memory for more details.

Consultancy
Over the years I’ve consulted with a number of companies and organizations. Most of it is survey design, research and data analysis. Contact me if you’re interested in my services.
Past clients:
At the start of COVID-19 pandemic I was happy to volunteer for Data Versus Corona in attempt to use R
and Shiny
to visualize the pandemic.
