Dr Lucinda McRobb
Professional Overview
Dr McRobb joined the Neurosurgery group at the Faculty of Medicine and Health Science lead by Professor Marcus Stoodley in January 2014. She is a scientist with over 20 years of research experience in microbiology, biochemistry, cell biology and vascular biology. She received her PhD from the University of Sydney in 2008 and has held postdoctoral positions at The Heart Research Institute in Sydney and the Centre for Vascular Research (University of NSW).
Areas Of Research Interest
Dr McRobb is interested in understanding the pathogenesis of vascular disease and vascular abnormalities and developing methods to treat them. Her previous studies have investigated the role of androgens (male hormones) in driving atherosclerosis and vascular calcification and the development of small molecule inhibitors for the treatment of vascular restenosis after angioplasty and vascular stent placement. Dr McRobb’s current research studies in the Neurosurgery group aim to develop vascular targeting agents for the treatment of brain arteriovenous malformations (AVMs). This first involves identifying novel and specific molecular targets in gamma-radiated AVMs. Pre-clinical models and proteomic analysis will be used to identify up-regulated proteins expressed on the surface of cells lining the vascular wall after gamma knife surgery.
Dr Sarah Hemley
Professional Overview
Dr Hemley completed her PhD thesis in 2011 and was awarded her PhD in April 2012, receiving the Macquarie University Dean’s Award for Excellence in Graduate Studies. The same year she joined the Macquarie Neurosurgery Team as a Postdoctoral Research Fellow. She has developed a keen interest in neuroscience research, specifically investigating spinal cord cyst formation (syringomyelia) and fluid circulation in the spinal cord. She has contributed to numerous publications related to the pathophysiology of syringomyelia and presented at internationally recognised conferences on the topic.
Dr Carlo Russo
Professional Overview
Dr Carlo Russo is Senior Data Scientist at the Joint Research Centre in Ispra, VA (Italy) and Honorary Senior Lecturer at the Computational NeuroSurgery (CNS) Lab at Macquarie University, Sydney. He works on application and development of algorithms for image analysis in the neurosciences using non-linear geometry, including fractal analysis, and deep learning.
He has previously worked as Research Associate at the CNS Lab and for more than 15 years at Humanitas Research Hospital in Rozzano, Milan (Italy), where he developed innovative software and hardware aimed to introduce computer aided automatic diagnosis tools both in research and in clinical workflows. His studies include the application of fractal geometry and artificial intelligence to histopathology and radiology images. He is author and co-author of 31 peer-reviewed articles (h-index 13) and 5 patents.
Dr Sunil Unnikrishnan
Professional Overview
Sunil has a PhD in Biomedical Engineering from the University of Virginia, USA. Before joining Macquarie Neurosurgery, he was a post-doctoral researcher in radiology at the Children’s Hospital of Philadelphia. His primary research experience is in preclinical and clinical ultrasound imaging in the context of tumour and cardiovascular imaging. He has also undertaken research in computational and experimental fluid mechanics as applied to physiologic flows.
At MQN, he is working on a variety of projects involving the biomechanics of spinal fusion surgeries, machine learning, and magnetoencephalography in neuromodulation. He is also currently researching the clinical outcomes of neurosurgical procedures such as revision Chiari decompression, bypass for intracranial lesions, lumbar microdiscectomy, and gamma knife radiosurgery for large arteriovenous malformations.
Dr Joel Berliner
Professional Overview
Dr Berliner joined the Neurosurgery Research group lead by Professor Stoodley in January 2016. That year, he completed a Master of Research in Clinical Medicine at the Faculty of Medicine, Health and Human Sciences, Macquarie University. He continued to a PhD in 2017 where he investigated the pathological processes leading to syringomyelia after spinal cord injury. Dr Berliner submitted his PhD in 2021 and was awarded the doctoral degree in 2022. Since then, he has been working as a Postdoctoral Research Fellow. He is currently working in clinical research with people who live with Chiari 1 malformation and syringomyelia. He hopes to increase our understanding of these two conditions and improve outcomes for people in the future.
Dr Berliner also works in laboratory research, where he is investigating the affect physiological variables have on the development and progression of syringomyelia.
