Biography

I am a Professor of Statistics in the Department of Statistics at University of Al Qadisiyah. My current methodological research interests focus on Bayesian variable selection in quantile regression models. I am also interested in cosmology and gravitational lensing. Specifically, I am interested in understanding how small fluctuations in the early universe grew to form the large-scale structure observed today (see , Gravitational lensing by f(R,T) gravity).
