Subash Raj Susai

Subash Raj Susai is a Lecturer at the Royal College of Surgeons in Ireland (RCSI) School of Dentistry, with a background spanning dentistry, neuroscience, and psychiatry. Previously, he served as a Research Lecturer in Psychiatry and Physiology at RCSI (May 2024-May 2025) and as a Lecturer at Sinhgad Dental College and Hospital in Pune, India (2013-2015). His academic journey includes a PhD from RCSI (2019-2022), an MSc in Neuroscience from Trinity College Dublin (2017-2018), and an MSc from Saveetha Medical University, Chennai (2010-2013).

Dr. Susai's educational background reflects his interdisciplinary career path:

• PhD, Royal College of Surgeons in Ireland (2019-2022)
• MSc in Neuroscience, Trinity College Dublin (2017-2018)
• MSc, Saveetha Medical University, Chennai (2010-2013)
• Bachelor in Dental Surgery, Tamil Nadu Dr. M.G.R. Medical University (2004-2009)

Dr. Susai's research focuses on the intersection of neuroscience, proteomics, immunology, and psychiatry, with particular emphasis on investigating immune biomarkers in neuropsychiatric disorders. His work employs advanced proteomic quantification methods, especially mass spectrometry and multiplex assays, to explore the relationship between inflammatory markers and mental health conditions. He has made significant contributions to understanding how childhood trauma, cannabis use, and omega-3 fatty acids influence inflammatory processes that may contribute to psychiatric disorders.

His publication record demonstrates a clear trajectory of research exploring the inflammatory basis of psychiatric conditions. Recent work has focused on soluble urokinase plasminogen activator receptor (suPAR) as a marker of chronic inflammation in psychiatric disorders, the role of complement and coagulation pathway proteins in predicting treatment response, and the relationship between polyunsaturated fatty acids and psychosis-spectrum outcomes. His research often employs longitudinal approaches and large cohort studies like the Avon Longitudinal Study of Parents and Children (ALSPAC).

Dr. Susai has been actively involved in multiple research collaborations, contributing to studies examining the proteomic predictors of psychosis transition in clinical high-risk populations and the inflammatory subgroups across psychiatric disorders. His work has been published in high-impact journals including Schizophrenia Bulletin, Biological Psychiatry, and Translational Psychiatry, demonstrating the significance of his contributions to the field.
