Student and Postdoc SIG


The OHBM Student and Postdoc SIG provides a community of shared interests for OHBM trainees. We provide opportunities for professional, personal and career development and represent the needs of trainees to the OHBM Council and the wider organisation. We also promote the achievements of trainees within the organisation and to the wider neuroimaging community. The SIG organises the Monday Night Social and career development events at the annual meeting as well as running the online, international mentoring programme.

OHBM Student and Postdoc SIG Executive Group

Hajer Nakua
- Chair

BSc Psychology, Neuroscience and Behaviour (McMaster University, Canada); PhD Candidate, Institute of Medical Science -Collaborative Program in Neuroscience (University of Toronto, Canada).

Hajer Nakua is a 3rd year PhD student at the University of Toronto. She is interested in using advanced statistical, mathematical and computational techniques to investigate brain-behaviour relationships related to psychiatric disorders. Hajer's lab is in the Center for Addiction and Mental Health and her research focuses on using multi-modal brain imaging (structural MRI, functional MRI and diffusion weighted imaging) to find associations between behavioural constructs and brain network properties linked to emotional regulation in children. More broadly, Hajer is interested in using advanced statistical, mathematical and computational techniques to investigate brain-behaviour relationships related to psychiatric disorders. Hajer is also passionate about science communication and uses social media as an avenue to disseminate neuroscience research in both English and Arabic (instagram: @itshajernakua).

Megan Campbell
- Secretary

Postdoctoral Research Fellow in Systems Neuroscience, Hunter Medical Research Institute Imaging Centre & School of Psychology, The University of Newcastle, Australia.
PhD, The Queensland Brain Institute, The University of Queensland, Australia.
MSci (Neuroscience), The Queensland Brain Institute, The University of Queensland, Australia.
BPsychHons (first class), James Cook University, Australia.

Dr Megan Campbell is a postdoctoral research fellow at the Hunter Medical Research Institute Imaging Centre and the School of Psychology in the University of Newcastle, Australia. Megan obtained her PhD in the field of cognitive-behavioural neuroscience, and has recently taken up her first postdoctoral position in the Systems Neuroscience Group lead by Professor Michael Breakspear.
Her previous work investigated the overlapping sensorimotor processes underlying interpersonal interactions, within healthy adult cohorts. By using Bayesian models to explain behavioural and neural datasets Megan described mechanisms for the context-dependent modulation of automatic imitation responses, a feature of how humans prepare responses during interactions with others. Now Megan is applying her experience in functional neuroimaging, behavioural paradigms and computational approaches to new projects focusing on clinical populations. In particular, modelling dynamic brain networks and cognitive-emotional processes in order to understand, differentiate and improve diagnoses for psychiatric illnesses such as bipolar disorder and schizophrenia.; @MegaEJ_Campbell


Linden Parkes
- Treasurer

BSc (Hons.) Psychology and Psychophysiology, Swinburne University of Technology, Melbourne, Australia; PhD Neuroscience, Turner Institute for Brain and Mental Health, Monash University, Melbourne, Australia; Postdoctoral Research Fellow, Department of Bioengineering, University of Pennsylvania, Philadelphia, USA.

Dr. Linden Parkes is a postdoctoral research fellow in the Complex Systems Group in the Department of Bioengineering at the University of Pennsylvania. He received his Ph.D. in Neuroscience at Monash University, Melbourne, Australia. His research focuses on the link between individual differences in psychopathology and the brain, with a particular focus on the role of dimensional psychopathology phenotypes that cut across traditional diagnostic categories. Working with longitudinal data, he applies a combination of Magnetic Resonance Imaging (MRI), machine learning, bifactor modeling, and network control theory to examine whether neuroimaging predicts the emergence of psychopathology throughout childhood and adolescence.

Elvisha Dhamala

- Social Coordinator

BSc Neuroscience, McGill University, Montréal, Canada; PhD Candidate, Department of Radiology, Weill Cornell Medicine, New York, USA

Elvisha Dhamala is a Neuroscience PhD candidate at Weill Cornell Medicine in the CoCo Lab. How white matter pathway integrity and neuronal co-activation patterns in the brain vary between the sexes and relate to complex cognitive functions remains a mystery in neuroscience. Elvisha's research integrates neuroimaging, connectomics, and machine learning approaches to explore multimodal brain connectivity patterns underlying sex and cognition. She is particularly interested in developing sex-dependent machine learning models to elucidate neurobiological underpinnings of different behavioural, cognitive, and disease phenotypes in order to reduce sex biases in neuroscience and medicine.

Elvisha is also passionate about education outreach and community engagement. She teaches an undergraduate-level neuroscience course at local correctional facilities and works with different organisations to help primary and secondary school students in diverse settings learn about careers in STEM. In her free time, Elvisha enjoys travelling, hiking, kayaking, and reading.

Kevin Sitek
- Social Media and Communications Manager

BA, Linguistics, Cognitive Science (UC Berkeley); PhD, Speech and Hearing Bioscience and Technology (Harvard University)

Kevin Sitek is a postdoctoral associate in the Neuroscience department at Baylor College of Medicine. He studies human subcortical sensory processing using functional, anatomical, and diffusion-weighted MRI. Currently, he's working with collaborators at the Max Planck Institute for Biological Cybernetics in Tübingen, Germany to investigate multisensory processing in the superior colliculus with ultra-high field fMRI. During his PhD, Kevin worked at MIT with Dr. Satra Ghosh on mapping the human subcortical auditory system.

Jennifer Ferris
- Career Development and Mentoring Manager

BA (w. hons) Psychology - University of British Columbia; M.S.c in Neuroscience – University of British Columbia

Jennifer Ferris is a PhD Candidate at the University of British Columbia in Vancouver, Canada. Jenn uses structural neuroimaging techniques to research stroke and cerebral small vessel disease. Jenn is especially interested in how comorbid cardiovascular and metabolic diseases impact the brain. Outside of the lab Jenn enjoys spending time in the beautiful B.C. mountains- she is an avid trail runner.
