Clinical Data Engagement


Our team specializes in utilizing cutting-edge technology to study human variation, with a focus on developing molecular insights into disease risk prediction, surveillance, and intervention. By combining integrated omics and clinical data science, we are able to target complex diseases like obesity and mental illness that affect millions globally. Our research covers chronic diseases across the entire lifespan - from pediatric to elderly populations - with a special emphasis on the underrepresented Asian population. Our collaborations with renowned Singaporean cohorts, health clusters, and public sector entities like MOH and HPB, as well as national platforms such as the National Precision Medicine SG10K-Health study and PREPARE, enhance the translational potential of our findings. Additionally, we have formed strategic partnerships with top nutrition and probiotics companies to advance the development of innovative solutions for disease prevention and intervention.

We also leverage our expertise in omics and clinical data science to develop mobile applications that provide a comprehensive and personalized healthcare experience. Our approach integrates next-generation diagnostic tests from precision medicine research and electronic health records to provide up-to-date and actionable insights into an individual's health journey. By empowering clinicians and increasing scientific literacy, our apps facilitate informed decision-making for better health outcomes. In addition to developing health apps, our expertise in multi-omics data analytics has led us to create open-source analytics tools such as GEM, cell type reference panels for infant epigenetic studies, and omics databases such as iMOM-db and iDAD-db. These resources cover molecular phenotypes of ethnic variation and diet-exposure, including complex molecular traits (eg. eQTLs and meQTLs) and contribute to advancing our understanding of personalized medicine.

Combining our learnings from omics and clinical data science, we have been using the multi-dimensional data to develop mobile applications that can enhance personalized healthcare experience. These apps can be powered by next generation diagnostic tests developed through precision medicine research and electronic health records to provide a holistic and an up-to-date assessment of an individual’s health journey. These tools can not only provide an actionable intervention roadmap for clinicians but can also increase the scientific literacy of individuals to make better health choices. Beyond health apps, our experience in multi-omics data analytics has led to development of open-source analytics tools (eg. Gene Environment Methylation tool - GEM), cell type reference panels for infant epigenetic studies, and omics databases such as iMOM-db and iDAD_db that cover molecular phenotypes of ethnic variation (eQTLs and meQTLs) and diet-exposure (sperm sncRNA).
