Rate My Professor Sarah Johnson

Sarah Johnson's research centers on digital information and digital signals processing, particularly error correction codes that ensure secure and reliable data transmission across technologies like mobile phones, the Internet, and digital television. Her pioneering work on low-density parity-check codes has influenced communications reliability and implementation. She collaborates with industry, notably Quintessence Laboratories, on quantum key distribution for ultra-secure systems. In biomedical engineering, she develops technologies using digital signal processing to monitor patient recovery post-injury or disease. Key publications include her book, Iterative Error Correction: Turbo, Low-Density Parity-Check and Repeat-Accumulate Codes (Cambridge University Press, 2010), and recent papers such as "Belief Propagation Decoding of Primitive Rateless Codes" (IEEE Communications Letters, 2026) and "Shear Stress Targeted Delivery of Nitroglycerin to Brain Collaterals Improves Ischaemic Stroke Outcome" (Advanced Science, 2025). With over 5,800 citations on Google Scholar, her contributions have significant academic impact. Awards include the NSW Premier’s Prize for Excellence in Engineering & Communications Technologies (2017), Pro Vice-Chancellor’s Award for Research Excellence (2007), ARC Future Fellowship, ARC Postgraduate Research Fellowship, and CSIRO postgraduate scholarship. She co-founded HunterWISE to support women in STEM and serves as Series Editor for Internet of Things in IEEE Communications Magazine.
