Fajar specialises in computational systems biology, with a focus on metabolic modelling and host–pathogen model integration.
Fajar is a Master of Bioinformatics student researcher at The University of Queensland with a focus on genome-scale metabolic modelling. His work centres on the reconstruction, curation, and analysis of bacterial metabolic models, particularly Haemophilus influenzae, using constraint-based modelling frameworks such as COBRApy. He studies genotype–phenotype relationships through flux balance analysis, gene essentiality analysis, and model refinement. His broader research aims to integrate microbial models with host environments to better understand metabolic interactions in complex biological systems. He is also developing an interest in predicting metabolic pathways from defined input and output compounds using machine learning and graph-based approaches.
