Trosolwg

My lab focuses on understanding and treating neurodegenerative diseases, particularly Parkinson’s and Huntington’s diseases. We are interested in understanding the manifestation of motor and non-motor (cognitive, neuropsychiatric) dysfunctions in degenerative diseases using lesion, viral vector and genetically modified rodent models. We are also investigating the ability of novel cell (hESC- and hiPSC-derived) and gene therapies to alleviate these impairments and optimising these treatments for clinical application.

I am the Associate Theme Lead for Mind, Brain and Neurosciences.

Bywgraffiad

My PhD (2005-2010, Prof M Good) investigated neural network dysfunction using mathematical modelling in a mouse model of Alzheimer's disease, with a particular focus on amyloid-induced amydala and hippocampal dysfunction.

My post-doctoral research (2010-2015, Prof S Dunnett) aimed to understand basal ganglia dysfunction in Parkinson's and Huntington's disease and to explore the use of human fetal and novel stem cell derived therapies to alleviate the behavioural impairments.

I was then awarded a Senior Research Fellowship from Parkinson's UK (2015-2018) to investigate the ability of human stem cell derived cell therapy products to ameliorate cognitive impairments in rodent models of Parkinson's disease.

I have recently commenced a Senior Lectureship in the neuroscience department and my lab is exploring several new avenues. We are seeking to understand the mechanisms of neural dysfunction using novel DREADDs manipulations, undertaking PET/MR imaging and using newly created models of disease. We are also studying the impact of novel cell therapy approaches and newly optimised gene therapies on cellular and behavioural function.

Addysgu

I am currently the Assessment Lead on 3rd year module Neurobiology of Brain Disorders and I teach on the Cellular and Molecular Biology module at Master's level. I run practicals to teach histological and immunohistochemical assays and microscopy skills using rodent brain tissues.

I am a personal tutor for Neuroscience and Biomedical undergraduate students.

My lab focuses on understanding and treating neurodegenerative diseases, particularly Parkinson’s and Huntington’s diseases. We are interested in understanding the manifestation of motor and non-motor (cognitive, neuropsychiatric) dysfunctions in degenerative diseases using lesion, viral vector and genetically modified rodent models. We are also investigating the ability of novel cell (hESC- and hiPSC-derived) and gene therapies to alleviate these impairments and optimising these treatments for clinical application.

Some current research questions that are being addressed include: 

Can hPSC-derived dopamine grafts alleviate non-motor dysfunctions in Parkinson's disease?

Is Pax6 a useful biomarker of transplant maturation and efficacy?

Does neuroinflammation play a role in hPSC-derived dopmine graft-induced dyskinesias?

What is the impact of dopamine production from AAV vectors on striatal-dependent cognitive function?

Can we modulate gene expression to improve neurite outgrowth and synapse formation from hPSC-derived dopamine grafts?

Can hPSC-derived medium spiny neuron transplants form synaptic connections and alleviate non-motor dysfunctions in models of Huntingtons' disease?
