Profile Summary

Dr Dada (fondly called Chris) is an environmental health microbiologist, specializing in the fate, transport, detection, and control of pathogens in environmental media. He completed a Masters degree in Water Science, Policy and Management at Oxford University’s Center for the Environment which equipped him to provide high-level advisory support to decision makers within the water sector. His PhD research focused on the molecular characterization of faecal indicator bacteria and antibiotic-resistant pathogens in aquatic recreational environments. In addition to his microbiology skills, Chris completed a Postgraduate Certificate programme in Data Analytics. Chris extensively applies sophisticated programming tools such as Python, SAS Enterprise Guide and SAS Enterprise Miner for big-data analysis and visualization. At QMRA Data Experts, Chris provides specialist expertise in microbiology, quantitative microbial risk assessment (QMRA), predictive modelling and big data analysis to a range of projects.
