Mark A Johnson

Mark A Johnson is a Clinical Associate Professor in the Department of Clinical Sciences at the University of Illinois. His work focuses on improving patient safety and healthcare outcomes in intensive care units (ICUs), particularly through research on medication safety, electronic health record (EHR) implementation challenges, and innovative diagnostic methods for infectious diseases like SARS-CoV-2. He has contributed to studies on reducing medication errors, optimizing EHR systems, and developing ultrasensitive viral detection techniques. Johnson collaborates widely across disciplines, including engineering and public health, to address complex healthcare challenges. His recent work includes a high-impact study on mitigating SARS-CoV-2 transmission at a large university, demonstrating leadership in pandemic response strategies.
