**About the Editors**

**Sara Lal** holds a BSc from Sydney University and M App Sc, PhD and Graduate Certificate in Higher Education (GCHE) from the University of Technology Sydney (UTS) and DipLaw from Legal Profession Admission Board, NSW, Australia. She held a National Medical and Health Research Council (NHMRC) Clinical Research Training Fellowship from 2001, and was appointed as an academic at UTS in 2004. Presently, she leads the Neuroscience Research Unit and is Deputy Leader of the Medical Science Discipline in the School of Life Sciences. Her main areas of research are in neurosciences, cognitive sciences, medical physiology, cardiovascular and diabetes research, psychophysiology, fatigue/sleepiness, worker safety and performance, including areas of digital and wearable medical/health technologies. She has attracted national and international competitive research grants and research consultation. She has published/presented over 200 varied types of scientific works including journal papers, refereed conference papers, books, chapters, reports, and abstracts.

**Thomas Penzel** graduated from physics (1986), human biology (1991), and physiology (1995) at the University Marburg, Germany. In 2006, he moved to Berlin where he is the Director of research of the Interdisciplinary Sleep Medicine Center at the Charite´ – Universitatsmedizin ¨ Berlin (Germany). In 2001, he received the Bial award for Clinical Medicine in Portugal, in 2008, the Bill Gruen Award for Innovations in Sleep Research by the American Sleep Research Society, and in 2014, the distinguished research award by the Chinese Sleep Research Society. He is secretary of the German Sleep Society and Adcom member of IEEE EMBS. He was IEEE EMBC 2019 conference chair, and co-chair of earlier conferences of EMBC, and World Sleep Society in 2005 in Berlin, and national conferences on sleep and biotelemetry. He is Editor-in-Chief of the journal Sleep and Breathing. He has published more than 300 journal papers (Pubmed), about 80 book chapters, and edited several books. His interests are sleep medicine, biomedical signals, and the cardiovascular and neural system related to sleep–wake regulation.

**Ann M Simpson** has a BSc (Hons) and a PhD (Veterinary Science) from the University of Sydney. Professor Simpson joined the staff at the University of Technology Sydney (UTS) in 1994 and since 2002 has held the position of Professor of Biochemistry. She is Director of the UTS Research Centre for Health Technologies. Her areas of expertise are biochemistry, molecular biology, and cell biology. Her main research interest is the gene therapy of diabetes mellitus. She was the first to show a liver cell can store insulin in granules and she has engineered two liver cell lines to store and secrete insulin to a glucose stimulus. One of these cell lines has reversed diabetes in an animal model. In particular, her work now focuses on novel strategies to deliver the insulin gene directly to the liver of diabetic animals, so far reversing diabetes with normal glucose tolerance in chemically diabetic rats, spontaneously diabetic mice, humanised mice, and a diabetic pig model by direct delivery of the insulin gene to the animal's livers using a viral vector.
