Research interests

Optimization problems, in particular related to compressed sensing and sparse coding, machine learning, applications with biomedical signals.


Dr. Nicolae CLEJU [PhD.'12, MSc.'09, BSc.'07] obtained his Ph.D. summa cum laude in 2012 from the Technical University "Gheorghe Asachi" of Iaşi, and has since joined the Faculty of Electronics, Telecommunications and Information Technology, where he now holds a position of associate professor. Dr. Cleju teaches and has taught multiple classes in signal processing, information theory, C programming and related disciplines.

Between 2014-2022 dr. Cleju has worked with Continental Automotive Romania, developing signal processing solutions for the automotive industry and, more recently, working on AI solutions for smart traffic infrastructure.
