Dr Alexey Larionov


I was graduated as a medical doctor in Russia in 1992 (I.P.Pavlov State Medical University, St.Petersburg).  For several years I combined clinical work in emergency medicine and in medical oncology.  In 1998 I completed PhD in experimental oncology (N.N.Petrov Institute of Oncology, St.Petersburg, Russia).  My PhD project focused on extra-gonadal aromatase activity in breast cancer patients.  Supported by the Royal Society I did my postdoctoral fellowship in Edinburgh University.   Shortly after this I switched my clinical career in Russia to a research career in the UK.  During more than 10 years I continued research in Edinburgh University on endocrine aspects of breast cancer (see selected publications below, or the longer list at ).  Citation metrics in Sep 2015: h-index 15, average citation per paper 25 (calculated by ). 

Working with data-rich methods (qPCR & microarrays) I became interested in data analysis.  After a period of self-education in bioinformatics (mainly R-scripting for microarray projects) I completed MSc in bioinformatics (Cranfield University, 2012). In my MSc project I developed approaches for classification of endocrine resistant breast cancers from transcriptomic datasets using published multi-gene signatures (see summary at ).  My current work includes bioinformatics support for exome sequencing projects in heritable breast cancer (Marc Tischkowitz group, Academic Laboratory of Medical Genetics, School of Clinical Medicine, University of Cambridge). 

My career so far has been heavily biased toward research. However, I always enjoyed teaching when the opportunities arose. I supervised MSc project in Molecular Medicine in Cranfield University; I run a Clinical Pharmacology seminar for undergrads in Edinburgh University; I completed PgCert in University Teaching/ Academic Practices; and I am a Fellow of The Higher Education Academy (UK).
