I am a senior researcher at Tiberiu Popoviciu Institute of Numerical Analysis, Romanian Academy, Cluj-Napoca, Romania. I completed my Master's degree in Numerical Analysis from Babeş-Bolyai University, Cluj-Napoca, Romania, in 1997, and obtained a PhD in Mathematical Analysis from the same university in 2005. My research interests include: numerical analysis, time series theory, automatic trend estimation, quantitative finance, approximation of functions by means of linear and positive operators, and umbral calculus.
