Тренутно је запослен као виши предавач на АТУСС ВИШЕР у Београду, као редовни професор на Факултету за друштвене науке, УПАНС и као консултант за информациону сигурност у компанији SECIT Security Consulting. Радио је хонорарно на Факултету за компјутерске науке и Факултету за инжењерски менаџмент. Објавио је неколико књига и научних библиографских јединица (в. попис одабраних у делу референце). Рецензент у високо-категорисаним часописима, на међународним конференцијама и релевантним поглављима у књигама. Уредник секције за рачунарске науке часописа Journal of Computer and Forensic Sciences, постављен одлуком ректора КПУ. Гостујући уредник специјалног издања Recent Advances in Numerical Algorithms for Machine Learning часописа Axioms (М22). Научно-истраживачки рад обухвата примену машинског учења, препознавања облика и обраде природних језика у информационој сигурности, као и биометријске и крипто-биометријске системе, криптологију и теоријско-информациони приступ развоју заштитних механизама.
