I'm a Researcher at the Institute of Physics Belgrade, Scientific Computing Laboratory.
I am interested in applying computational methods to social science through AI/ML, network science, and open-source tools development.

Software
transforEmotion
R packagetransforEmotion is an R package for multimodal sentiment and emotion analysis using transformer models. It supports text, image, and video emotion recognition, and includes tools for dynamic exploratory graph analysis of emotion time series.
- Text, image, and video emotion recognition
- Zero-shot classification with transformer models
- Dynamic network analysis of emotion dynamics
- Open-source, cross-platform
YClient-Reddit
Python app
YClient-Reddit is a fork of the YSocial client application, modified to better support Reddit-like LLM agent social simulations.
YSocial is a client-server application that implements a digital twin of an online social media platform using Large Language Models (LLMs).
Key Modifications for Reddit-Like Simulation
- Adapted agent prompts and interaction logic to mimic Reddit-style posting, commenting, and voting
- Modified data structures and simulation parameters to reflect Reddit's community and thread-based organization
- Adjusted recommender systems and feed generation to better align with Reddit's content discovery mechanisms
- Additional configuration options and scripts for Reddit-specific experiments
YSocial-Reddit-Explorer
Flask appDashboard for inspecting YSocial agent-based simulations and performing interventions (content/user moderation, what-if scenarios) with a lightweight Flask backend.
- Browse threads, users, votes, and interactions
- Apply moderation and observe downstream effects
- Export subsets for analysis
