I review some aspects of development of the astroinformatics in Serbia. Special attention is paid to the funding and educational challenges. As we recently joined the LSST project, we expect huge impact on Serbian science especially in the Big Data areas. Among others, our contribution will be in building simulator of alerts for the astronomical community and prototype of the CEP engine for analyzing data generated by the survey. 1. OVERVIEW OF ASTRONOMY IN SERBIA There are two main institutions with significant number of astronomers in Serbia: Astronomical Observatory in Belgrade (AOB) and Department of Astronomy, Fac- ulty of Mathematics, Belgrade University (DAFM). AOB employs about twenty re- searchers with PhD at different stages of their career and about fifteen PhD students. DAFM has about ten tenured/tenure track professors and about 15 Phd students. There are few astronomers at other institutions such as Institute of Physics Belgrade, Institute of Nuclear Sciences Vinˇca, Department of Physics University of Kragujevac, Department of Physics University of Niˇs, Department of Physics University of Novi Sad. Funding of Astronomy (and generally science) in Serbia is grant based. Serbian Government currently funds the following eight projects with significant astronomical component: ◦ Astrophysical Spectroscopy of Extragalactic Objects (led by Luka Popovi´c) ◦ Gravitation and the large scale structure of the Universe (Predrag Jovanovi´c) ◦ Emission nebulae: structure and evolution (Dejan Uroevi´c) ◦ Influence of collisions on astrophysical plasma spectra (Milan Dimitrijevi´c, Zo- ran Simi´c) ◦ Stellar physics (Gojko Djuraˇsevi´c) ◦ Visible and Invisible Matter in Nearby Galaxies: Theory and Observations (Srdjan Samurovi´c) ◦ Dynamics and kinematics of celestial bodies and systems (Zoran Kneˇzevi´c, Rade Pavlovi´c) ◦ Astroinformatics: application of IT in astronomy and close fields (Darko Jevre- movi´c). 7 D. JEVREMOVIC´ 1. 1. INTERNATIONAL COLLABORATION Astronomers from Serbia were and are involved in many internationally funded projects. The first European project we were involved was Virtual Atomic and Molecular Data Center VAMDC (Dubernet et al. 2010, Jevremovi´c et al. 2009). More details in section 2.1.3. Project BELISSIMA (BELgrade Initiative for Space Science, Instrumentation and Modeling in Astrophysics) started in 2010. It is funded by European Comission under the FP7 REGPOT schema. The BELISSIMA will be concluded in June 2015. Main goals are: ◦ Reinforcement of the scientific potential of AOB (and, therefore, Serbian as- tronomical and space sciences) through increase of both width and depth of its overall research activities, observational and theoretical, as a consequence of ”brain gain”. This will be operational on several levels, in both theoretical and observational aspects of envisioned future research activity. ◦ Purchase, installation and testing of new observing equipement (telescope ”Mi- lankovi´c” with1.5 m-class mirror, to be installed on Astronomical Station Vi- dojevica ◦ Human potential, training and public outreach. Exchange of know-how and experience between EU research institutes and AOB. Training of AOB re- searchers in observational astronomy techniques and work towards establishing collaboration with other observatories in Europe and worldwide ◦ Popularization of Astronomy and Science Stardust, the Asteroid and Space Debris Network, is an Advanced research net- work we participate in. One PhD student from Greece started his PhD thesis work at AOB in the September of the last year. Astromundus is a master program in astrophysics. Five universities are involved - namelly Insbruck, Goettingen, Padova, Rome and Belgrade. Typically, 4-6 students attend classes in Belgrade during the fall semester of the second year of their course. Also, few students are doing their master thesis research in the final semester in Bel- grade (either under our supervision or under joint supervision between two partners). We actively participate in the following COST actions: ◦ MP0905 - Black Holes in a Violent Universe 24 March 2010 - 01 June 2014 ◦
