Published in 17th National Conference of Astronomers of Serbia, 2017
The topic is the participation of contestants from Serbia in international contests in astronomy: 6th IOAA in Brazil 2012, 7th IOAA in Greece 2013 and the Saint-Petersburg Olympiad in 2013. Also, organisation and preparations of contestants, volunteer work of trainers and financial problems. Contribution of Mathematical Gymnasium in Belgrade. A presentation of contests within Serbia, which serve for the purpose of selecting contestants for international contests. Organisation and events during international contests, as well as the success of Serbian contestants.

Published in Winter Simulation Conference 2021, 2021
Simulation on directed graphs is an important method for understanding the dynamics in the systems where connectivity graphs contain cycles. Discrete Stochastic Heterogeneous Simulator (DiSH) is one of the simulation tools with wide application, which uses regulator values to calculate state updates of regulated elements. Here we present a new simulation approach DiSH-trend which also takes into account the trends in regulating elements. We demonstrate the features of trend-based regulation, as well as hybrid regulation, which is a combination of the trend- and level-based approaches. The modeling capabilities are demonstrated on a small toy model, showcasing different functionalities. Real-world capabilities are demonstrated on a larger network model of food insecurity in the Ethiopian region Oromia. Adding trend-based regulation to models results in increased modeling flexibility, and hybrid regulation improves qualitative dynamic behavior prediction. With appropriate data, DiSH-trend becomes a powerful tool for exploring intervention strategies.

Graduate course, University of Pittsburgh, Computational and Systems Biology Department, 2020
This course introduces students to the theory and practice of modeling biological systems from the molecular to the population level with an emphasis on intracellular processes. Topics covered include kinetic and equilibrium descriptions of biological processes, systematic approaches to model building and parameter estimation, analysis of biochemical circuits modeled as differential equations, modeling the effects of noise using stochastic methods. A range of biological models and applications are considered including gene regulatory networks cell signaling, molecular motors, and developmental biology.
