• Professor of Social Statistics & Demography
• Advisory Board member of the Cathie Marsh Institute
• Associate Editor of Demographic Research

I hold a PhD in Economics from the Warsaw School of Economics, Poland. I joined the Social Statistics Department as a Lecturer in August 2015.  Between 2022 and 2025, I served as Head of Department. Before that, I was the Department Postgraduate Director (2020/21) and the Department Undergraduate Teaching Director (2017–2019). I also led the Statistical Modelling Research Group at the Cathie Marsh Institute from 2019 to 2023.

Earlier in my career, I worked as a Research Fellow at the ESRC Centre for Population Change and the Southampton Statistical Sciences Research Institute (University of Southampton). I was also a Researcher at the Central European Forum for Migration and Population Research (Polish Academy of Sciences and the International Organisation for Migration), and a Teaching and Research Assistant at the Department of Applied Econometrics at the Warsaw School of Economics.

I work on developing statistical methods for modelling and forecasting complex social processes, with a particular focus on migration and mobility, and integrating traditional and new forms of data. I also have a general interest in time series analysis and forecasting, hierarchical models, Bayesian computational methods, survey methods, opinion polls and ageing.
