Mary is presently the Principal Investigator of the Bill and Melinda Gates Programme: Setting the Post-Elimination Agenda for Kala-azar in India (see https://speakindia.org.in/). The focus of the operational research is to work towards sustained elimination of visceral leishmaniasis in the Indian Sub-continent. The work comprises four synergistic pillars: surveillance, mathematical modelling, disease transmission and health systems. The consortium consists of the following partners: with Indian Council of Medical Research, National Centre for Vector-Borne Disease Control Programme, Banaras Hindu University, Institute of Tropical Medicine Antwerp, Rajendra Memorial Research Institute of Medical Sciences RMRIMS, Institute of Public Health, PATH, UNION, CARE India, International Centre for Diarrhoeal Disease Research, Bangladesh.

In addition, Mary is the LSHTM PI on a collaborative project led by Royal Danish Academy of Fine Arts Schools of Architecture Design & Conservation with the Ifakara Health Institute, Tanzania funded by the NoVo Foundation. The project will generate a risk-assessment of vector-borne diseases in urban Dar-es-Salaam based on deep learning and remote sensing.

Mary is also on the steering committee of a collaborative project with Wolf-Peter Schmidt (PI) and the Christian Medical College Vellore, India funded by the MRC to understand the epidemiology of scrub typhus and rickettsial infections in a highly endemic rural setting in south India.

Furthermore, Mary is the primary supervisor of Freddy Sarathchandra who is undertaking a PhD, LIDo DPT-funded, defining wing-beat patterns of mosquitoes for automated detection.
