Agnieszka Jach

I am an Associate Professor (Subject Statistics) at the Department of Finance and Economics. I joined Hanken in 2013. Prior to that, I worked as an Assistant Professor (positive tenure evaluation) in the Department of Statistics at Universidad Carlos III de Madrid, Spain. I completed my PhD in Statistics in 2006 at Utah State University, USA, and between 1996-2001 I studied Mathematics at the University of Science and Technology in Wroclaw, Poland.

In my research, I pursue topics related to time series analysis with applications to finance and other fields.

Research key-words: co-movement, thick-pen transform, wavelet transform, multi-scale phenomena, high frequency, self-normalization, subsampling, parameter-dependent convergence rates, heavy tails, long memory, frequency and wavelet domains, semi- and non-parametric methods.

I teach mathematics, statistics and quantitative finance at undergraduate and graduate levels, and supervise MS students in Finance.
