Since 2011, Mr Kollie has established and headed the Liberian Integrated NTDs Prevention and Control Programme and is based within the Ministry of Health and Social Welfare. He developed the NTD country master plan which forms the operational national guide for the next 5 years.

Under his leadership the Liberian programme is making excellent progress in MDA control of Lymphatic Filariasis, Onchocerciasis, Schistosomiasis, Soil-transmitted Helminthiasis (STH) where treatment coverage has not gone below 75%, respectively. Alongside this, he is making significant progress in the development and application of new monitoring and evaluation criteria tailoring activities effectively with difficult on-the-ground terrain.

For example, in order to evaluate the impact on health, disease intensity and disease transmission, using parasitological indicators for STH and schistosomiasis, 38 sentinel sites have been used to monitor the large-scale distribution of Praziquantel (PZQ). 

He has Master’s degrees from the James P. Grants School of Public Health, BRAC University, Bangladesh and Cuttington University Graduate School Liberia.
