2015: Joel Castro (Kraftchenko) Head of the Endometriosis Research Group (SAHMRI)Adjunct Associate Professor, University of Adelaide
A/Prof. Joel Castro Kraftchenko (known as Joel Castro on its publication records) is a principal investigator and Head of the Endometriosis Research Unit at the Visceral Pain Research Group, located at the South Australian Health and Medical Research Institute (SAHMRI). He is an expert in the field of visceral nociception and pain and his research focuses on understanding the causes, and developing treatments, for chronic visceral pain associated with endometriosis. A/Prof. Castro’s research has contributed 62 peer-reviewed manuscripts in top ranked journals including Nature (x3), Cell, Nature Communication, Gastroenterology, Gut, PNAS, Pain, and JCI insight. Together these outputs have been cited over 5380times (Google Scholar July 2025) with and h-index of 38.
A/Prof Castro’s research focuses on studying the sensory afferents innervating visceral organs, to understand how pain is detected from these sites. He investigates the ion channels/receptors expressed within these afferents (which govern their function); how these afferents are altered in animal models of endometriosis, and what changes in ion channel/receptor expression occur, to trigger these alterations and cause chronic visceral pain.
Throughout his career A/Prof. Castro has contributed to the establishment and characterisation of two clinically relevant animal models of endometriosis. He has developed several techniques crucial to identify functional, structural, and molecular characteristics of sensory fibres innervating visceral organs in health and disease states. He has used this knowledge to propose novel non-invasive, non-addictive approaches to reduce chronic pelvic pain in these disorders.
