BIOSTATISTICS AND BIOINFORMATICS
Dennis Wang, Senior Principal Scientist I
Dennis Wang helms A*STAR IHDP’s Bioinformatics platform, which integrates expertise in computer science with biology and mathematics to support analytics with large and/or multi-dimensional data. Additionally, he holds the Academy of Medical Sciences Professorship (Chair in Data Science) at Imperial College London.
Wang’s research focuses on translating patterns in the human genome into actionable information that accelerates the development of treatments for complex diseases. Specialising in big data analysis, drug development (small molecules and biologics), algorithmic development, software design, web service development, genomic profiling, and statistical inference, his experience includes applying machine learning and statistical approaches to identify patterns from large genomic data sets and providing clinically actionable biomarkers to drug development teams.
Having worked in both academia and industry, Wang enjoys mentoring junior bioinformaticians and clinicians wanting to apply genomics to patient care and marrying research and teaching to promote data driven approaches for personalising medicines. Among his most significant projects are a crowd-sourcing machine learning challenge to predict drug combinations involving partners from pharma and technology industries; improving whole genome sequencing methods for the diagnosis of complex diseases, such as dementia, motor neurone disease and COVID-19; and developing computational methods for integrating omics data from patients to advance precision medicine for treating lung cancer and pulmonary hypertension.
He has received numerous awards, including the EPSRC Healthcare Technologies grant in 2021, the Rosetrees Seedcorn Award and Academy of Medical Sciences Springboard Award in 2019, the MRC Proximity to Discovery Award in 2017, and the AstraZeneca Innovative Medicines Award in 2016.
Wang obtained his Bachelor of Science in Computer Science, Microbiology and Immunology from The University of British Columbia, and both his Master of Philosophy in Computational Biology and PhD in Biostatistics from the University of Cambridge.

Andrea Cremaschi, Senior Scientist I
Andrea Cremaschi’s field of expertise is in statistical modelling for biomedical applications, developing methodologies in the field of Bayesian Statistics (often including nonparametric aspects), graphical models, and analysis of datasets involving variables of diverse nature.
His research interests include both the methodological and applied aspects of statistics – particularly within the Bayesian framework, Bayesian nonparametrics, the use of flexible mixture models for inference in scenarios where the data present peculiar features, concern model-based cluster analysis, and the use of graphical models for inference in dataset characterised by a sparse dependency. Besides analysing data from GUSTO in the neuroscience and metabolic fields, he also works on manuscripts with collaborators to develop novel methodologies in the field of Bayesian nonparametric statistics with applications. He received an honourable mention for the Lindley Prize by the International Society for Bayesian Analysis (ISBA) in 2019.
Cremaschi obtained his Bachelor and Master’s degrees in Mathematical Engineering from the Polytechnic University of Milan, and his PhD in Statistics from the University of Kent in the U.K. He did his postdoctoral fellowship in at the Yale-NUS College.

Huang Jian, Senior Scientist I
Huang’s research interests lie in molecular epidemiology focusing on cardiometabolic health, neurodevelopment, and neurodegeneration. He has a wealth of experience in multi-omic data analysis and causal analysis using causal effect decomposition (based on the counterfactual framework) and Mendelian randomisation. Specifically, Huang investigates the causal relationship of maternal and early-life risk factors with child cardiometabolic and neurodevelopmental health, and the molecular mechanisms underlying this relationship (genomics, epigenomics, metabolomics, and proteomics).
He was granted the Singapore National Medical Research Council, Open Fund - Young Individual Research Grant (NMRC OF-YIRG) in 2022 for a three-year project to study the relationship between early-life metabolic risk and suboptimal neurodevelopment.
Huang obtained a Bachelor of Science in Pharmacy from Jinan University, and his Master of Public Health and PhD in Epidemiology and Biostatistics from The University of Hong Kong. He did his postdoctoral fellowship at Imperial College London investigating the causal relationship of lifestyle factors and molecular biomarkers with risk of Alzheimer's disease.

Evelyn Lau, Senior Scientist I
A significant research study she worked on involved investigating the early and long-term impact of the expression of oncogenic PIK3CA mutation to gain insights into genetic and epigenetic events that arise at early stages leading up to tumour formation, where these signatures could potentially be exploited therapeutically. She was also involved in several other studies to understand how genetic variants affect regulation of genes involved in immune diseases, in a cell-type specific manner, using functional genomic approaches.
Lau obtained her Master of Research in Tissue Engineering for Regenerative Medicine from the University of Manchester, and PhD in Cancer Cell and Molecular Biology from University College London.
