I have extensive expertise in quantitative and qualitative health policy and systems research. The overarching focus of my research is on improving the quality of healthcare and governance of the health sector.

My main research areas are: conflicts of interest affecting health policies; governance of the private healthcare sector; One Health and Global Health Security; gender differences in health; antimicrobial resistance; and tuberculosis (TB) control.

I been the lead investigator of several studies including (currently) an intervention trial in Pakistan to address pharmaceutical incentive-driven prescribing, policy research on informal and invisible healthcare providers in Cambodia, and investigating conflicts on interest hindering antimicrobial resistance control. In my earlier work I have conducted a randomised trial of simple patient instructions to improve TB diagnosis in women and a multi-country implementation research project funded by the STOP TB Partnership to test a new system to involve low-cost private diagnostic laboratories in diagnosing and treating TB. Over the years, I have collaborated closely with the Pakistan National TB Control Programme, leading an important operational research study to assess the effectiveness of local versus international drugs for treating multi-drug resistant TB.

I am also active in research and advocacy to address inequitable hierarchies in global health. For example, examining who is present and absent in research funding allocation decisions, increasing national ownership of health policies and illuminating gender and ethnic disparities in senior positions in global public health institutions.

I believe in '360 degree' capacity building in which all members of the team, including collaborators, identify expertise they can share and would like to gain.
