Danielle Bruns, PhD is an Assistant Professor in the Division of Kinesiology & Health at the University of Wyoming. She received her PhD in Human Bioenergetics from Colorado State University and completed her postdoctoral training in the Division of Cardiology at the University of Colorado-Denver. Dr. Bruns’ research focuses on the molecular mechanisms underlying cardiac disease, with a specific focus on the impact of age and biological sex on heart failure pathogenesis and therapeutic outcomes. Recently, Dr. Bruns has become interested in nocturia, an age-related condition that affects an enormous number of older adults. Nocturia is a condition associated with abnormalities in water handling with poor therapeutic options. Her collaborative team is interested in understanding the mechanisms that underlie nocturnal polyuria and whether exercise can ameliorate this highly significant condition.

Associate Professor Sofia Enhörning is a scientist at the department of Clinical Sciences at Lund University and a medical doctor at the Department of Internal Medicine at Skane University Hospital in Malmö, Sweden. She graduated from medical school at Lund University and obtained her Ph.D degree in Internal Medicine at Lund University. Her research has focused on genetical and epidemiological studies of the vasopressin system and its links to metabolic and cardiovascular disease. She is currently focusing on experimental intervention studies, investigating the role of hydration on the vasopressin system and glucose regulation, and on epidemiological studies, investigating the links between the vasopressin marker copeptin and cardiometabolic disease. Dr. Enhörning has received the Scandinavian Society for the Study of Diabetes (SSSD) Young Investigation Award and the ”best clinical diabetes thesis of the year” award in 2012 from the Swedish Society for Diabetology. In 2016, she was awarded with the Hydration and Kidney Health Grant.

Professor John Fawell has worked in the field of drinking water quality for over 40 years, first at the UK Water Research Centre and later as an independent consultant. He has been involved in research on and risk assessment of a wide range of drinking water contaminants and constituents. He has been a member of the team working on the WHO Guidelines for drinking water quality since 1986 and is an author on many WHO advisory and supporting documents. He remains a member of the WHO expert committee on the Guidelines and works closely with WHO regional offices, particularly European Office through which he was one of the main authors of the advisory document for the European Commission on the revision of the European drinking water directive. Professor Fawell is a visiting professor at Cranfield University Institute for Water Science and has provided advice to governments in many parts of the world.

Nate Willis is a 4th year Ph.D. candidate in the Division of Nutritional Sciences at the University of Illinois Urbana-Champaign. As a research assistant in the Neurocognitive Health Behaviors Laboratory under the tutelage of Dr. Naiman Khan, he is investigating the impact of nutritional intake on cognitive functioning with a specific focus on water intake and hydration status. His research on the relationships between hydration markers, gut microbiota and inflammation won the ECRA in 2022 and he is currently collecting data for his dissertation project investigating the impact of a water intake intervention on the gut microbiota, markers of gastrointestinal inflammation, and cognitive functioning in adults. Nate hopes to continue working in hydration science after his expected graduation in the Spring of 2023.

Professor Evan Johnson did not start off as a hydrationist but his passion has grown throughout his career. Coming from a background on the physical activity side of the health equation, Professor Johnson found his interest veering toward hydration and its impact on thermoregulation while researching athletes such as football players and soldiers during training operations.

Completing his PhD at the University of Connecticut in 2014 and continuing his training as a post-doctoral associate at the University of Arkansas, Professor Johnson’s research has centered on water intake and type 2 diabetes. On July 1, 2015, during the H4H Annual Scientific Conference, Professor Johnson presented his current research which investigated the impact of low water intake on blood glucose regulation. His current research focuses on the relationship between water intake, physical activity, and nocturia in older adults.
