Dr Eirini Marouli


Lecturer in Computational Biology




Dr Eirini Marouli is an Assistant Professor in Computational Biology at the William Harvey Research Institute, Queen Mary University of London.

She graduated with a BSc in Biology and a MSc in Clinical Biochemistry from the University of Athens, Greece. Dr Marouli was awarded a PhD in Genetics from the University of Athens studying the genetic overlap between type 2 diabetes and psychiatric disease. Eirini joined the William Harvey Research Institute in July 2014, as a Greek State Scholarships Foundation Fellow, where she acquired analytical skills in statistical genetics. She completed her postdoctoral training with Professor Panos Deloukas. During this period, she had a leading role in the GIANT (Genetic Investigation of Anthropometric Traits) consortium, investigating the role of rare and low-frequency coding variants in human adult height (Marouli et al., Nature 2017).

Dr Marouli’s research interests lie at the interface of genetics, bioinformatics and statistics, in order to achieve a better understanding of human biology and disease prediction with the use of “Big Data”. Her work focuses on using human genetics to identify genes that influence common diseases and quantitative traits, including height and adiposity. Dr Marouli implements novel computational methods, including machine learning, to gain biological insights from human genetic and phenotypic data.

She has a leading role in the large international consortium (GIANT) that has discovered almost all of the genetic variants that are known to influence human height and obesity related traits. Dr Marouli has also leading work and contributions in global consortia (GLGC, CHARGE CARDIoGRAMplusC4D) for complex traits and diseases.

In addition to gene discovery efforts, Dr Marouli is also interested in genetic-epigenetic approaches to complex phenotypes. Dr Marouli also specialises on the genetics of thyroid function and disease. Her recent work integrates the use of genetic data and a battery of state of the art approaches, for causal inference and mendelian randomisation and machine learning to elucidate the genetic interplay between risk factors and disease.
