Биографија

РС:

Рођен 1975. године у Зајечару. Дипломирао на Универзитету у Новом Саду 2006. године. Докторску дисертацију одбранио 2013. године на Универзитету Сингидунум у Београду, на студијском програму напредни системи заштите. Тренутно је запослен као виши предавач на Одсеку ВИШЕР у Београду, као редовни професор на Факултету друштвених наука и Факултету за информационе технологије, као консултант за информациону сигурност у компанији SECIT Security Consulting и као члан лабораторије Joint Training Simulation & Analysis Center (BAS). Радио је хонорарно на Факултету за компјутерске науке и Факултету за инжењерски менаџмент. Научно-истраживачки рад обухвата примену машинског учења, препознавања облика и обраде природних језика у информационој сигурности, као и биометријске системе, криптологију и теоријско-информациони приступ развоју заштитних механизама.
