Overview
With a background in molecular biology, genetics and biostatistics/bioinformatics, Dr Dobril Ivanov joined the UK DRI at Cardiff with a Sêr Cymru Rising Star fellowship by the ERDF through the Welsh Government.
Dobril did an MSc in molecular biology followed by a wet-lab scholarship to study neurodevelopmental disorders at the MRC Centre in Cardiff. This project was one of the earliest to accurately estimate the frequency of VCFS deletions in patients with psychosis (https://doi.org/10.1192/bjp.183.5.409).
Dr Ivanov obtained his PhD in bioinformatics from Cardiff University in 2010, with one of the first studies to fully explore the similarities and differences of germline/somatic mutations in human tumour suppressor genes in a variety of cancers (https://doi.org/10.1002/humu.21483). During his first postdoc (MRC CNGG Cardiff University) he developed a novel computational approach that led to the observation that rare CNVs substantially increase one's susceptibility to developing schizophrenia (https://doi.org/10.1038/mp.2011.154).
Dr Ivanov completed his postdoctoral training at the European Bioinformatics Institute in Cambridge in Prof. Janet Thornton's group investigating neurodegenerative disorders and signalling mechanisms and biochemical processes by which insulin/IGF-1 signalling modulates lifespan in model organisms (https://doi.org/10.1016/j.celrep.2016.03.041 ). As a UK DRI Emerging Leader, Dr Ivanov leads research to link gene-expression profiles to a wide-range of Alzheimer-related phenotypes in humans, animal and iPSC models.
