MND Association Senior Non-Clinical Fellow
My group aims to provide insights into molecular underpinnings of RNP granule biology and their connection to human disease. Our overarching goals are:
- to establish how altered composition and metabolism of the two types of RNP granules, stress granules and paraspeckles, contribute to the pathogenesis of ALS and frontotemporal dementia (FTD);
- to discover and validate druggable targets for these devastating and currently incurable conditions;
- to identify novel chemical probes for modulation of RNAs and RNP complexes.
- Regulation of RNP granules paraspeckles and stress granules under acute and chronic stress and in disease states (cellular models) - currently funded by the MND Association and BBSRC.
- The role of RNA-binding proteins FUS and TDP-43 in ALS and FTD (cellular and mouse models; analysis in human post-mortem tissue).
- Therapeutic targeting of RNA and RNA-protein complexes (assay development and screening activities).

After graduating with an MSc degree in Genetics in 2008, I pursued a PhD in Biochemistry (both while in Russian Federation) which I completed in 2012. During my PhD training, supported by an EMBO fellowship, I contributed to the generation and characterisation of a unique mouse model of a fatal neurodegenerative disease, amyotrophic lateral sclerosis (ALS); report on this mouse model published in J Biol Chem was selected as Paper of the Year. I continued to develop this stream of research during my postdoctoral training at Cardiff University (Prof Buchman’s lab), where I spearheaded a number of projects focussing on (dys)metabolism of ribonucleoprotein (RNP) granules in ALS. In 2015, these studies were supported by a 3-year fellowship from the Medical Research Foundation. In 2018, I was awarded a 4-year senior non-clinical fellowship from the MND Association to start my own group at the Medicines Discovery Institute, a newly established Cardiff University’s translational unit. Since then, my research was also supported by the AMS Springboard award, the ISSF Translational Kick-Start award, a Welsh Government drug discovery grant and more recently, a research grant from the BBSRC. In September 2021, I moved to SITraN, University of Sheffield, to continue studies into the molecular pathogenesis of ALS and related disorders within a world-leading centre for neurodegenerative disease research.
