Dr Maria Yanez Lopez (Postdoctoral Research Associate)

Maria is a Research Associate in the Centre for the Developing Brain, King’s College London. Her research interests focus on the development of molecular magnetic resonance imaging (MRI) to investigate the biochemistry of neurological and psychiatric disorders, with a view to characterising disease onset, improving early diagnosis and assessment of therapy effectiveness. Her background includes research in traumatic brain injury and Alzheimer’s Disease, with techniques such as magnetic resonance spectroscopy (MRS) and chemical exchange saturation transfer (CEST), both at clinical fields (3T) and high fields (9.4T preclinical).

Her current work is focused on studying the balance between excitatory (glutamate) and inhibitory (Gamma Amino-Butyric Acid (GABA)) neurotransmitter levels in newborn infants who have a high familial risk of developing neurodevelopmental disorders, using edited 1H MRS methods. An abstract presenting this work was recently recognised by a Magnum Cum Laude award as one of the top 15% of abstracts at the ISMRM annual meeting 2020.

Dr Slava Karolis (Postdoctoral Research Associate)

Slava completed his PhD in the Institute of Cognitive Neuroscience (University College London) where he studied the topic of number representations in the human brain. His first postdoc was in the Institute of Psychiatry (King’s College London) where, as a member of the Neurodevelopment and Mental Health Group, he was working on the characterisation of anatomical and behavioural consequences of very preterm birth from adolescence into adulthood. He then spent several months in France (Institut du Cerveau et de la Moelle épinière, Hôpital de la Salpêtrière, Sorbonne) working on the atlas of brain regions that show functional hemispheric specialisation and characterising their structural connectivity. In 2018 Slava joined the developing Human Connectome Project as a member of the Analysis Group in FMRIB, Oxford, where he undertook studying signal properties of the in-utero functional MRI and developing an analytical pipeline for these data. He now continues this work as a PFIGist in the Centre for Developing Brain. His main research interest is fetal brain fMRI.

Sian Wilson (MRC CND PhD student)

Siân is an MRC-Sackler PhD student at the Centre for Neurodevelopmental Disorders, Kings College London co-supervised with Dr Jonathan O’Muircheartaigh and Professor David Edwards. She obtained a BSc Biochemistry at the University of York in 2018. During her undergraduate studies she spent a year at the Centre for Genomic Regulation, Barcelona in the lab of Prof. Mara Dierssen working on gene-environment interactions in a mouse model of Down’s Syndrome. Siân then completed an MSc Neuroscience at University College London, where she worked with Prof. Michael Hausser, characterising hippocampal neural ensembles using calcium imaging and optogenetics.

Siân joined the Centre for the Developing Brain at King’s College London in 2019, where she began her PhD working on fetal diffusion MRI, characterising the in-utero development of white matter tracts. Siân’s PhD work will aim to better understand how factors in the in utero and ex utero environment can perturb a healthy developing trajectory, which she is investigating by comparing structural brain MRI data of fetuses and neonates in India, the UK and the USA.

Ryan Stanyard (MRC CDT PhD student)

Ryan is an MRC PhD student at the Centre for the Developing Brain and Department of Forensic and Neurodevelopmental Sciences, King’s College London, co-supervised with Dr Dafnis Batalle and Professor Grainne McAlonan. Ryan obtained a BSc in Neuroscience and Psychology from Keele University in 2018, and then completed an MSc in Neuroimaging at King’s College London, where he worked with Professor Robert Leech and Dr James Cole, exploring the potential for near-real time active acquisition and processing of ASL data.

Ryan joined the Centre for the Developing Brain at King’s College London in 2019, completing an MRes in Biotranslational Medicine, where he began his PhD working on exploring computation models of whole brain connectivity using neonatal diffusion and functional MRI. Ryan’s PhD work will aim to better understand how the coupling of structure and function in the brain changes across the lifespan, primarily in neonates of differing degrees of prematurity. This work will leverage biophysical models of emergent brain activity and empirical EEG, diffusion and functional MRI data.

Dr Sara Neumane (Bettencourt Foundation fellow)

Sara has a double background and is qualified in France as an MD in Paediatrics (focusing on Neuropaediatrics and rehabilitation) but also has a PhD in Neuroscience (focusing on functional somatotopy, motor system and compensatory mechanisms in a pathological context).

Her research interests include studying structural & functional brain networks in typical and atypical development, sensorimotor system development and post-injury neuroplasticity, and functional outcomes following early acquired brain injuries.

Alumnus: Anna Lukens (Neonatal physiotherapist)

Anna worked with the team as a highly specialist neonatal physiotherapist on the neonatal unit at the Evelina London Children’s Hospital from 2017-2021. During this time she completed her MSc in Advanced Paediatric Physiotherapy at University College London and did a research project investigating the predictive validity of the Lacey Assessment for Preterm Infants which is used on the neonatal unit to identify infants at high risk of neurodevelopmental difficulties. From 2019-2021 she worked specifically on the EPSRC funded MAVEHA project to explore methods for quantification of spontaneous motor behaviour in neonates. She is now leading the neonatal physiotherapy service at King’s College Hospital.

Alumnus: Dr Sofia Dall’Orso (PhD student 2016-2019)

Sofia completed her PhD at Imperial College London in 2019, and is currently a postdoctoral research associate at Chalmers University Sweden and a visiting researcher at King’s College, London. She obtained her Physics BSc at the University of Bologna and the Neurotechnology MRes at Imperial College London as part of the EPSRC CDT (centre for doctoral training) programme. During her PhD, she combined engineering and imaging techniques with robotic tools to perform task-based fMRI on newborn babies. Her research on brain development focuses in particular on the sensory system, comprising investigating somatotopic mapping in the preterm brain and the study of associate learning between different sensory modalities. She aims to better understand how the somatosensory system develops and how it can be influenced by environmental exposure and early sensory experiences.

Alumnus: Dr Judit Ciarrusta (PhD student 2015-2019)

Judit gained her PhD with us at King’s College London in 2019 as part of Brainview, a Marie Curie Early Career Initiative investigating early autism risk markers. The focus of her PhD was on typical and atypical functional activity development using fMRI data from subjects with family history of autism (high risk) and without family history of psychiatric (low risk) to discern typical from atypical maturation mechanisms. The final goal was to understand the characteristics of typical brain development in order to discern MRI markers that can enable early identification of atypical development before behavioural symptoms emerge. Judit is now a postdoctoral researcher working on the EU-AIMS project at King’s College London.
