Karthikeyan  Bagavathy Shanmugam

Karthikeyan Bagavathy Shanmugam, PhD, serves as a Senior Biostatistician specializing in Computational Exposomics within the Gangarosa Department of Environmental Health at Emory Rollins School of Public Health. Before joining Emory University, Karthikeyan held a Researcher position at the School of Science and Technology at Örebro University, Sweden. He specializes in Exposomics and Metabolomics research, focusing on investigating the links between exposures to environmental chemicals and the pathogenesis of metabolic and non-communicable diseases. Karthikeyan is primarily responsible for conducting metabolomics studies in exposome research projects, operating at the interface of complex chemical mixtures of known and unknown chemicals, data processing, metabolite identification, and data analysis. He utilizes various methodologies including data integration and mining, pathway analysis, correlation network analysis, as well as multivariate and univariate statistical and Machine Learning methods to establish connections between environmental exposures and disease phenotypes.

After completing his Ph.D., he gained significant work experience at Computational Biology Group, The Institute of Mathematical Sciences (IMSc) in Chennai, India. He was extensively involved in a project titled 'Computational Systems Toxicology: Application of Network Biology towards Health Risk Assessment of Environmental Chemicals'. His contributions encompassed the advancement of computational models, workflow development, and the establishment of 5 knowledgebases dedicated to the fields of Toxicology and Environmental Health. For more information, please refer to his Publications.

In 2017, he earned his Ph.D. in Bioinformatics from Bharathidasan University, Tiruchirappalli, India, receiving a 'Highly Commended' recognition. His doctoral thesis, titled 'Studies on species differences and species selectivity of xenobiotic degrading Cytochrome P450 enzymes of human, mouse, and rat using Systems Biology approach' showcases his expertise in the field.

Furthermore, he actively contributes as a regular reviewer for esteemed journals including Environmental Science & Technology Letters, PLoS ONE, Heliyon, PeerJ, and Frontiers in Public Health.
