About
Joanna S. Semrau’s research lies at the critical intersection of nephrology, cardiac surgery, and neuropsychology, where she investigates how systemic medical events—such as acute kidney injury (AKI) and coronary artery bypass grafting (CABG)—impact brain function. Her landmark 2021 study, cited 12 times, provided the first quantitative evidence that AKI survivors suffer from subtle but measurable neurocognitive impairments, challenging the assumption that renal recovery equates to full neurological health. Semrau further advanced the field by developing novel, quantified metrics to assess pre-operative neurological dysfunction, demonstrating in her 2019 work that these baseline deficits strongly predict adverse outcomes after CABG. Her protocol study and feasibility trial on cerebral oximetry (rSO₂) have pioneered a non-invasive approach to monitoring brain oxygen levels during cardiac surgery, offering a potential tool to prevent postoperative cognitive decline. By rigorously quantifying what was once considered vague “post-surgical confusion,” Semrau has given clinicians objective benchmarks to predict, detect, and ultimately mitigate neurological injury in high-risk surgical and critically ill patients. Her work is essential reading for researchers in neurocritical care, perioperative medicine, and nephrology.
