Research interest

The key focus of my research over the years is the search for markers or molecules and their mechanisms in the pathogenesis of malaria and other diseases. Thus in the area of basic immunology research, I have  demonstrated record of successful and productive research projects in an area of high relevance in investigating molecules that are possibly involved in the pathogenesis of severe malaria.  I demonstrated for the first time that monocytes are important phenotype of cells that elicit nitric oxide in the killing or inhibition of growth of Plasmodium falciparum (Gyan et al Parasite Immunology. 1994). This finding provided valuable insight into the role of non-antibody mediation during immune response to malaria. Further to this I have carried out studies on the role of haptoglobin(Gyan et al ActaTropica, 2002), an acute phase protein, CD 163 (Kusi et al. Vaccine Immun. 2008) and endothelial progenitor cells(Gyan et al. Am J Trop Med Hyg. 2009) and their interaction or modulation of immune factors during an infection such as malaria.

 In addition I am involved as investigator in malaria vaccine trials. I was a co-investigator in the Phase Ib trial of the EBA-175 RII-NG vaccine in Ghana. Currently, I serve as a investigator/expert of a team of scientists investigatingimmune correlates of protection against malaria after vaccination with RTS,S/AS01E in the ongoing comprehensive Phase III double-blind, randomized, controlled multi-center trial.In recent years extended my research activities to other diseases including schistosomiasis, tuberculosis, diabetes, leishmaniasis and sickle cell disease

 I have a strong passion in train next generation of scientists in Africa through support in graduate students thesis work. I am currently involved in the  development of internship programs in global health for international students


Research Projects completed (within the past 5 years):

Phase 1, Double-Blinded, Placebo-Controlled Dosage-Escalation Study of the Safety and Immunogenicity of EBA-175 RII-NG Malaria Vaccine Administered Intramuscularly in Semi-immune Adults.The goal of this study was to assess the safety and reactogenicity (tolerability) of ascending dosages of EBA-175 RII-NG vaccine among healthy semi immune adult subjects given in 3 doses at 0, 1 and 6 months by IM injection.

Role: Co-Investigator


Multiplexed Detection of food and waterborne pathogens

The aim of the study was to identify multiple food and water-borne bacteria, protozoa and viruses simultaneously from a single sample.

Role: Collaborator

Role: Co-investigator

 Study immune correlates of protection against malaria after vaccination with RTS,S/AS01E: of a comprehensive immunological arm of a Phase III double-blind, randomized, controlled multi-center trial

The goal of this study was to investigate mechanisms of vaccine-induced protection against malaria Identify a correlate of vaccine-induced protection

Role: Co-Principal Investigator

cell immune responses

To define the initial protective immune responses targeting CSP upon vaccination with RTS,S/AS01E and to explain duration of protection by defining RTS,S/AS01E modulation of naturally acquired

humoral and cellular immunity to asexual BS parasites.

Role: Co-Investigator

 NIH Funded 1 R01AI099623-01       2012-2017
