Isaac Darko Otchere (PhD) is a biomedical research scientist who began his professional research work at Noguchi Memorial Institute for Medical Research (NMIMR) in 2011 as Research Assistant (Contract Staff) after his Master degree. He acquired his Doctor of Philosophy degree (PhD) in Biochemistry from the University of Ghana with a PhD in 2017. Prior to his PhD degree, He received practical training in Bioinformatics and Pathogen Genomics from the Swiss Tropical and Public Health Institute (Swiss TPH), University of Basel, Switzerland and the Wellcome Trust Sanger Institute, Cambridge University, United Kingdom respectively. His PhD thesis was titled “Comparative Genomics Analysis of Mycobacterium tuberculosis Complex Strains from Ghana”. He discovered from this work that the Tuberculosis causing bacteria called M. africanum which is restricted to West Africa is made up of genomically two distinct lineages whose diversity have potential implications on existing and future TB control tools. He also discovered potential TB bacilli lineage-specific epistatic interaction of drug resistance conferring and compensatory mutations among the dominant circulating TB bacilli in Ghana. In addition to his PhD training, he also received training on sample preparation and the use of the Matrix Assisted Laser Desorption Time of Flight (MALDI-TOF) mass spectrometry (MS) for rapid identification of bacteria and filamentous fungi at the NMIMR. As a PhD candidate, Isaac had the opportunity to assist the teaching and supervision of both undergraduate and post-graduate students of the University of Ghana to contribute to the capacity building of new generation scientists. Subjects assisted include Pathogen Genomics and Molecular Epidemiology at the Department of Biochemistry, Cell and Molecular Biology as well as Pharmaceutical Microbiology at the Department of Microbiology, School of Pharmacy, University of Ghana. He was encouraged by the response received from these supporting activities and hence motivated to remain in academia. His future aspirations are to use the invaluable applications of bioinformatics and biostatistics 1) to explore mycobacterial pathogenesis and disease control and to transfer the skills acquired while working on tuberculosis to other bacterial diseases

Research interests

Isaac Darko Otchere (PhD) is interested in the use of high throughput technologies to study the basis of bacterial evolution, pathogenesis and emergence of drug resistance. He is fascinated with bioinformatics discovery of biomarkers for monitoring treatment, development of vaccines, diagnostics as well as targets for drug development. He is also interested in the screening of plant extracts and synthetic compounds for anti-microbial activity towards drug discovery.
