Brief Statement of Research Interest

My main research interest lies in the area of survey sampling. I wrote my Ph.D. thesis on this topic. Specifically, I am interested in the use of Randomized Response Technique (RRT) Models in estimating prevalence of sensitive behaviors in society. RRT models have been used extensively in real-life situations in many countries, and I would like to replicate that effort to estimate some such sensitive behaviors among students in Lahore so that proper interventions can be considered. This is an important issue because we usually concentrate more on theory and less on real applications of that theory.
Going forward, I would like to involve my students more and more in my research by way of supervision of BS Projects and MS/M.Phil. theses, and potentially PhD theses. I will also continue to collaborate with other researchers in my field of research, such as my former Supervisor/Co-Supervisor and other co-authors.
