Marko KrstićData Scientist & IT Professional

IT Professional at RATEL

About Me

I received bachelor, master and PhD degrees in Electrical and Computer Engineering from School of Electrical Engineering (ETF), University of Belgrade. Although my interests during bachelor studies were closely related to the telecommunication networks, my research on master and PhD studies is mainly focused on recommender systems and machine learning techniques.

Since August 2013 I started working at Regulatory Agency for Electronic Communications and Postal Services (RATEL), firstly as Advisor in IT department and then as Senior Cyber Security Advisor at Serbian National Computer Emergency Team.

I actively participate in the working group 1 of COST CA17124 action Digital forensics: evidence analysis via intelligent systems and practices and in CASPER (Children Agents for Secure and Privacy Enhanced Reaction Cascading) project funded by H2020 Next Generation Internet Trust 2019001. Recently, I become Member Committee Substitute for COST CA18115 action Transnational Collaboration on Bullying, Migration and Integration at School Level.

Beside application of artificial intelligence in the area of cyber security and digital forensics, my current research interests are related to evidence based policy. I am holder of certificate provided by IDB10-1x: Data for Effective Policy Making course, created by Inter-American Development Bank.

Research interests



Recommender systems are software agents that help users choose objects of interest in the environments in which the number of available objects exceeds user’s ability to examine each of them individually. The main focus of my research are context-aware systems and systems that can work in resource limited environments.



Machine learning is a core subarea of artificial intelligence that provides systems the ability to automatically learn and improve from experience without being explicitly programmed.  The main focus of my research are neural networks, deep learning and algorithms that can provide real-time learning in resource limited environments.



Edge computing is a method of optimizing cloud computing systems by performing data processing at the edge of the network, near the source of the data. This reduces the communications bandwidth needed between consumer devices and the central data centre by performing analytics and knowledge generation at or near the source of the data. The main focus of my research are machine learning algorithms that can work under these conditions.



Information Security refers to the processes and methodologies which are designed and implemented to protect print, electronic, or any other form of confidential, private and sensitive information or data from unauthorized access, use, misuse, disclosure, destruction, modification, or disruption. The main focus of my research is protection of users’ privacy.

Marko is probably my best graduate and PhD student.

I have known him for last 7 years; during that time he worked on developing ELM models for
movie recommender systems.

Marko proved to be a hard working, creative, and reliable team member. I enjoyed working with him and hope to continue the collaboration in the future.

I collaborate with Mr. Marko Krstic on several research and engineering projects. Therefore, I can confirm that Marko has very strong maths, algorithms and engineering background. He will have my full support whenever he asks.
