Koh Woon Puay, Senior Principal Investigator (Human Development)
A senior principal investigator with A*STAR IHDP, Professor Koh Woon Puay is also Assistant Dean for Faculty Development at the NUS Yong Loo Lin School of Medicine, lead investigator for the Healthy Longevity Translational Research Programme at NUS Medicine, and Director of the Clinician-Scientist Development Unit at NUS Medicine.
Being a population health scientist, her research interest and expertise is in unravelling the epidemiology of chronic diseases of importance to òòò½Íøand the world at large, such as cancer, cardio-metabolic, musculoskeletal and neurodegenerative diseases. Being medically qualified in Singapore, and having had PhD training in experimental research and postdoctoral training in epidemiology, she seeks to integrate biology, medicine and epidemiology in etiological studies of the aforementioned chronic diseases.
Koh’s research incorporates her knowledge in clinical medicine and training in laboratory science with epidemiologic methods to unravel putative mechanistic pathways in disease etiology. Beyond establishing associations between exposures and risk of disease, her research uses molecular and genetic tools to identify modifiable factors (such as lifestyle factors) that could be applicable to disease prevention, or biomarkers (including but not limited to genetic markers) that could be developed for early detection or screening of disease. In addition to bringing benefit to the scientific community, she also aims to translate her research into public health outcomes by providing evidence for the foundation of public health education and policy in Singapore.
Since 2003, Koh has been the principal investigator of The òòò½ÍøChinese Health Study. Together with local and overseas co-investigators, she has examined lifestyle and dietary factors associated with chronic diseases common among Singaporeans using this cohort, and has co-authored about 400 scientific papers in peer-reviewed international journals, including several noteworthy and novel scientific contributions of reports on dietary, genetic and lifestyle factors that are of importance to Asian populations. The òòò½ÍøChinese Health Study is an example of world-class epidemiologic research that integrates rigorous prospective study design with cutting-edge biochemical measures that provide better information for causal inference. The study represents a unique constellation of strengths highlighting the importance of òòò½Íøas a hub for biomedical research: a well-defined motivated study population leading to low non-response and nearly complete follow-up, strong expertise in epidemiology and biochemical measurements, and an Asian setting that importantly complements studies conducted in western countries.
For her groundbreaking research efforts, the Ministry of Health, òòò½Íøawarded her the NMRC Clinician Scientist Award (Senior Investigator Category) for the years 2014 to 2019 and 2020 to 2025. In 2016, she received the Duke-NUS Medical School Dean’s Excellence Award 2016 for outstanding accomplishment in research.
Koh obtained her MBBS from the National University of òòò½Íøand her PhD in Immunology from The University of Sydney.

Ong Yi Ying, Principal Scientist I (Human Development)
Besides her role at A*STAR IHDP, Ong Yi Ying is also a Research Assistant Professor at the National University of Singapore, a Principal Investigator with the Human Potential Translational Research Programme at the NUS Yong Loo Lin School of Medicine, and a Junior Editor for the Paediatric and Perinatal Epidemiology Journal.
Ong's research vision is to maximise human potential through a life course epidemiology approach, focusing on the interaction between multiple early life exposures using various growth modelling and mixture modelling techniques. From a life course perspective, building a strong foundation in early life has implications for many different aspects of health later in life, from physical to mental health. Her research on the Developmental Origins of Health and Disease (DOHaD) investigates how early life growth/nutrition influences child outcomes (such as cardiometabolic risk, neurodevelopment, and puberty). She also investigates objective prenatal biomarkers (plasma, tooth) of poor foetal growth for risk stratification, uncovering mechanistic insights, and potential interventions.
Her first research study investigated the developmental mismatch hypothesis, a major hypothesis in the field of DOHaD, which postulates that if the postnatal nutritional environment is richer than predicted from foetal nutritional cues, predictive adaptive responses may become maladaptive and lead to increased cardiometabolic risk. She subsequently investigated whether rapid postnatal growth after poor foetal growth might improve cognitive outcomes by compensating for inadequate brain development in the womb. Her third study addresses a key gap from “Barker’s hypothesis”. Seminal epidemiological studies by Barker et al., who started the field of DOHaD, have associated low birthweight with cardiovascular risk. She investigated whether the fat mass or fat-free mass component of birthweight was associated with cardiovascular risk.
She also studies several epidemiological cohorts, including Growing Up in òòò½ÍøTowards healthy Outcomes (GUSTO) and Project Viva.
Ong obtained her BSc in Life Sciences from the National University of Singapore, and her PhD in Epidemiology from the NUS Yong Loo Lin School of Medicine.

Ada Teo, Principal Scientist I (Human Development)
In addition to her role at A*STAR IHDP, Ada Teo is also an Associate Consultant at the Endocrinology department in the National University Hospital (NUH).
Having completed the Cambridge MB-PhD programme under A*STAR, Teo has been appointed Clinical Lecturer under the NUS Clinical Faculty Scheme. Her research is focused on the molecular genetics of hypertension, in particular aldosterone-producing adenomas. This led to the discovery of a subtype of adenomas with hallmark somatic mutations and a genotype-phenotype correlation. This work enabled both clinical insight and research expertise to be intertwined, with patients benefiting from, and contributing to, research into their own hypertension – culminating in her first publication in the New England Journal of Medicine in 2015.
Having serendipitously discovered a novel somatic mutation in adrenal tumours during her PhD years in Cambridge, her research has been focused on the molecular genetics of such tumours driving secondary hypertension. Having completed her Specialist Endocrinology training, she hopes to continue her research into primary aldosteronism, with the aim of bridging the gap between bench and bedside. She is excited by the possibility of combining clinical insight with research to pursue the goal of eventually developing therapies for hypertension personalised to each individual.
