Mark Osa Akrong is a Senior Research Scientist with the Environmental Biology and Health Division (Microbiology Section) of the Council for Scientific and Industrial Research - Water Research Institute (CSIR-WRI). He is a microbiologist with ten years of experience. He obtained his Bachelor’s degree in Biological Science at the Kwame Nkrumah University of Science and Technology in 2003, MPhil degree in Environmental Science at University of Ghana in 2009 and currently working on marine algae, hydrocolloid extraction and bacterial diversity on marine algae for his PHD under the Project “Sea Biorefinery Research project (SeaBioGha)” at the Kwame Nkrumah University of Science and Technology. He also worked as a Research Assistant at the International Water Management Institute. His area of research and development include: environmental microbiology, assessment and monitoring of water quality from different water resources: drinking water, boreholes, wastewater, freshwater and marine environment as well as packaged water. He has supervised undergraduate students, trained professionals and supervised many students on internship as well as national service personnel in the microbiology laboratory. He has more than 10 peer- reviewed articles in international journals.

Research Interest

Sanitation, Environmental microbiology, Marine ecology and, Urban agriculture

 The research activities comprise of field work and laboratory analysis. Research and development activities carried out involve water quality monitoring of surface and ground waters, wastewater, irrigation water, marine waters, etc; Water quality monitoring of major mining companies in Ghana, rivers, dams, lakes, municipal water supply. Microbiological quality of bottled water stored under different temperature conditions; Isolation and Small-scale production of Bacillus Sphaericus as Biological Control on Mosquito Larvae.

Current Project

  1. Sanitation and health status of low-income community in Accra (Funded by GCRF)
  2. Bacteria diversity in marine waters and seaweeds of economic importance, Seasonal variation of seaweed biomass and hydrocolloid yield in Ghana (Under Sea Biorefinery Research project).
