Sickle Cell Disease Genomics Network of Africa

Kumasi is the capital city of the Ashanti Region of Ghana, and hosts the Kwame Nkrumah University of Science and Technology (KNUST) and the Komfo Anokye Teaching Hospital (KATH), which are the two collaborating institutions for SickleGenAfrica in Kumasi. KNUST is the second largest public university in Ghana, with six main colleges for teaching and research while KATH is the largest tertiary hospital in the northern sector of Ghana. KATH has been running the Newborn Screening for Sickle Cell Disease Programme since 1995 and has a comprehensive Sickle Cell Clinic, the Kumasi Centre for Sickle Cell Disease. The Kumasi site has been the site for the Organ Damage in Sickle Cell Disease Study (ORDISS) which longitudinally followed about 1,000 SCD patients for organ damage. ORDISS is the pilot study for SickleGenAfrica. These factors make KATH the best place for our study in Kumasi.



Ezekiel Bonwin Ackah

Ezekiel is the Biomedical Scientist of at the Kumasi site. He ensures that samples are taken, processed and stored according to study designed standard protocols. Further, he is responsible for DNA extraction, certain investigations and shipment of all samples from Kumasi to the hub.


He earned his degree in Medical Laboratory Technology at KNUST. He has a 4-year working experience: 1 year in training at KATH and the remaining as a research laboratory scientist on ORDISS at KCCR. Joining this study is a strong force to enhance his understanding of the genetics and genomics of sickle cell disease, while keeping up-to-date with advancements in the management of the disease, and to help translate these into patient care.


Outside of work, he loves to listen to music, watch movies, read or go on a hike.



Caleb Sarfo Osei-Wusu

Caleb is the Data Manager at the Kumasi site. His responsibilities include planning and implementing efficient and secure procedures for data collection, handling and analysis. Also, he will assist with reports and data extraction when needed, troubleshoot and provide guidance on the maintenance or modification of data related issues.

He holds an undergraduate degree and postgraduate degree in public health (MPH) from KNUST. He has worked as a Research Assistant and Data Clerk/Analyst on several projects at KCCR. These include Research on Diabetes among African Migrants (RODAM), Cohort of Hypertension and Diabetes (CHAD) and Severe Typhoid in Africa (SETA) studies.

His hobbies are reading and listening to music.


Joseph Sarfo Antwi

Joseph is the Community Liaison Officer. His role is to use focus group discussions to assess the network’s impact on local communities within and nearby Kumasi. This role is connected to the community engagement working group.


His first degree was from University of Ghana, Accra, with an MPhil in Reproductive Physiology in view, from KNUST.


Being part of the SickleGenAfrica team is paramount to increasing his understanding in sickle cell genomics, as well as improving the quality of care he gives to patients and their families.


Joseph has been with the center for Newborn Screening Project since 2000, and a part of the team for the Education and Counselling Component of the Project since 2002. Mr. Sarfo is one of 14 certified genetic counselors in Ghana.


Outside of work, he enjoys music and sports.
