Charalampos (Babis) Rallis completed his PhD studies on Developmental Biology and Genetics at the National Institute for Medical Research (London, UK) under the supervision of Prof Malcolm Logan working on Vertebrate Limb Development and associated congenital syndromes. He then worked as a Postdoctoral Fellow with Prof David Ish-Horowicz, FRS at the Cancer Research UK (London, UK), studying vertebrate somite formation, axial stem cells and single-cell expression profiling. In 2009, Babis joined University College London as a research associate working with Prof Jurg Bahler towards a global perspective of cellular aging using pharmacological and genetic interventions and genome-wide approaches. Babis utilizes Synthetic and Systems Biology approaches as well as Genetic and Pharmacological interventions to study gene and protein networks that affect cellular and organismal growth, stress and lifespan. He runs a number of interdisciplinary projects from revealing the genetic basis of drug resistance to identifying pro-ageing and and anti-ageing genetic, epigenetic and environmental factors. His research outputs impact on the field of nutrition, growth regulation and cancer, bioprocessing and ageing.
Ageing is associated with the gradual decline of physiological functions both at the cellular and organismal levels and is the major risk factor for multiple diseases, including cancer, diabetes, neurodegeneration and cardiovascular problems. The study of specific disease processes has long been a major focus of research. However, fundamental aspects of the ageing process are an essential part of the problem. A range of interventions that increase lifespan have an analogous effect on healthspan and importantly can ameliorate age-related pathologies. Exploring ways to slow or reverse ageing will impact, therefore, on multiple disease occurrences in the population and reduce the severity of disease symptoms. Such interventions target signalling pathways such as the target of rapamycin-TOR that affects lifespan from yeast to humans.

We focus on highly conserved nutrient-responsive pathways and transcription factors and utilise the fission yeast S.pombe as well as human and mouse tissue culture systems. We aim to uncover the workings of genetic and non-genetic factors in cellular ageing and disease that will enhance our knowledge for developing pharmacological biogerontology interventions. Such approaches will ultimately protect or delay from age-related pathologies and contribute to a healthier ageing population. We are particularly interested in the relationships between cellular growth and bioenergetics, macromolecular quality control mechanisms and stress as well as organelle communication systems during normal and pathological conditions.
