Evelina Charidemou

Background

I began my scientific journey studying Biochemistry at Imperial College London, where I graduated with first-class honours. My early research experiences sparked my interest in metabolism and its intricate regulatory mechanisms, leading me to pursue a PhD in Professor Julian Griffin’s group at the University of Cambridge. During my PhD, I explored how specific amino acids influence insulin resistance via de novo lipogenesis, mastering advanced metabolomic, lipidomic, and bioinformatic techniques. While I always knew I wanted to stay in science, it was during my final year of PhD research that I became particularly fascinated by the interplay between metabolism and epigenetics. At the time, the field of metabolism was rapidly evolving, with growing recognition of its connection to epigenetic regulation.

This inspired me to take on a new challenge, and in 2019, I was awarded a prestigious Marie Curie Individual Fellowship to integrate metabolomic and epigenomic approaches at the University of Cyprus. Since then, I have continued to explore how metabolic pathways influence gene regulation by developing interdisciplinary methods that integrate molecular biology, biochemistry, analytical chemistry, and computational tools, and I now pursue this research as an Assistant Professor at the University of Nicosia, focusing on the intricate connections between metabolism and epigenetics.

Research

My research focuses on the intricate relationship between metabolism and epigenetics, exploring how these two fundamental processes influence human health and disease. By integrating cutting-edge metabolomics, epigenomics, and proteomics approaches, my team investigates how epigenetic modifications regulate metabolic pathways and contribute to disease progression, particularly in metabolic disorders and cancer. A key focus of my work is the epigenetic control of metabolism in the liver, where I study how hyperacetylated histones drive lipid synthesis and metabolic dysregulation in conditions like insulin resistance, fatty liver disease, and hepatocellular carcinoma. Using cell culture techniques and patient biopsy samples and advanced mass spectrometry techniques, we aim to identify novel epigenetic biomarkers with potential clinical applications.

Another major research area is the epigenetic regulation of metabolic memory in the eye, particularly in diabetic retinopathy (DR). My group investigates how persistent epigenetic changes contribute to DR progression even after glycemic control is restored. Through cell culture and diabetic mouse models, we seek to uncover early epigenetic biomarkers and develop strategies to improve patient outcomes.
