Tehreem is a doctoral candidate at the Bartlett School of Construction and Project Management, UCL. Her research interests lie in infrastructure financing, particularly railways in the first era of globalisation. During this era, railways had an eminent role and were claimed as the principal single determinant of the levels of investment, national income and employment of local and international governments. Her dissertation work explores themes of foreign direct investment and sovereign debt in the railway industry during this period. She is also exploring the impact of these factors on the changing structure of the industry at the turn of the century with many railway companies witnessing consolidation through either mergers or nationalisation. She writes for the business pages of The Express Tribune and for The Property Chronicle.
