Following graduation from Neuroscience at Trinity College Dublin with First Class Honours and a University Gold Medal, Dr Roisin McMackin undertook a PhD in Clinical Medicine from 2016-2021 at Trinity College Dublin investigating electrophysiological biomarkers of ALS, supported by an IRC Postgraduate Award. Having been awarded her Doctorate with no corrections, Dr McMackin subsequently continued her research postdoctorally as recipient of a prestigious MNDA Non-Clinical Fellowship (2021-2022). Dr McMackin began her role as Assistant Professor in the Discipline of Physiology in October 2022, and now leads a team of research students who use electrophysiology based measures to understand brain function in health and disease. She has since been awarded a number of highly competitive project grants, including an ALS Finding A Cure Early Diagnostics Initiative Award and funding from the Galen Hilary Weston Foundation under the Characterisation of Novel Biomarkers for Neurodegenerative Diseases of Ageing program. Dr McMackin was awarded the ENCALS 2025 Young Investigator Award in recognition of outstanding contribution to the field of ALS research, as well as the Neuroscience Ireland Early Career Researcher Award for her contribution to the field of neuroscience research. Dr McMackin's research is supported by the Motor Neurone Disease Association UK, the ALS Association, The Galen Hilary Weston Foundation, the Irish Health Research Board and Research Motor Neurone, in addition to previous support from the Irish Research Council. Dr McMackin teaches across across a number of undergraduate and postgraduate courses, including Neuroscience, Human Health and Disease, Physiology, Medicine, Clinical Neuropsychology, Biomedical Engineering, Biochemistry and Medical Device Design, in addition to providing international training courses on electrophysiological methods. Dr McMackin is the Associate Director of Equality, Diversity and Inclusion for the School of Medicine. She is also the Education Officer and Trinity College representative for Neuroscience Ireland, as well as a member of the Women In Research Ireland Committee. Dr McMackin is also an Associate Editor of Brain Communications, the Q1 open access sister journal of Brain.

Project Title
 Electromarkers of ALS: Detecting abnormal brain network function before ALS symptoms emerge in C9orf72 mutation-prevalent families.
From
2023
To
2027
Summary
It is well established that a long period of degeneration occurs in amyotrophic lateral sclerosis (ALS) before the symptoms begin. However, diagnosis of ALS currently depends on muscle weakness emerging. As ALS cannot be diagnosed until symptoms are apparent, potential drug treatments cannot be offered until the nervous system has already been extensively damaged. This dramatically limits the chances of the treatment halting or reversing the effects of ALS. A measurement that can detect ALS at an earlier stage, before clinically discernible signs emerge, is urgently needed. Those carrying long hexanucleotide repeat expansions in the C9orf72 gene are at greater risk of developing ALS and/or frontotemporal dementia (FTD). We and others have demonstrated that measurements of nervous system function, recorded with electroencephalography (EEG) and transcranial magnetic stimulation (TMS), can directly detect ALS/FTD-related changes in brain function prior to symptoms being detected. We now aim to perform a larger, more extensive study in individuals carrying the ALS/FTD-associated C9orf72 mutation, to determine the most informative brain function changes that are predictive of if/how the disease will emerge.

My research includes the use of electrophysiology, including electroencephalography (EEG) and transcranial magnetic stimulation (TMS), to investigate neural network function in health and neurodegenerative diseases. My research aims are (i) to improve understanding of the cellular, neurochemical and and network physiology captured by electrophysiological measurements and (ii) to use electrophysiological measurements to progress understanding of neurodegenerative disease mechanisms, to identify diagnostic and prognostic biomarkers and to improve the outcome measures used to test potential therapies in neurological clinical trials. I have a particular interest in amyotrophic lateral sclerosis (ALS), the most common form of Motor Neurone Disease, and Huntington's Disease. I am also actively involved in preclinical drug development, in collaboration with Dr Julie Kelly, Associate Professor of Neurology in TCD, in addition to consulting on the application of electrophysiology in international clinical trials for The Science Behind Ltd. I am also passionate about equality, diversity and inclusion in medical academia and research. Within this I have several developing research projects: 1. Development and assessment of a taught laboratory practical to educate students on the importance of recognising and accounting for diversity in physiological research, working in collaboration with Prof. Sean Roe and Prof. Mary McGahon of Queen's University Belfast. 2. Development of an international working group to establish recommendations for the training of early career researchers who work with individuals with MND in a research context. 3. Investigation of gender-related differences in physiological systems
