Recipients of the R.W. “Bill” Hamilton Medical Research Grant

In 2016, Divers Alert Network established a $10,000 research grant in honor of Dr. R.W. “Bill” Hamilton, who conducted research on dive physiology and the treatment of injured divers. Dr. Hamilton authored numerous papers, reports and workshop proceedings, and was instrumental in the early development and emergence of technical diving. Here are the first four recipients.

Jens-Christian Meiners, University of Michigan

Mechanics of Gas Bubble Formation and Dissolution in Spinal Cord Tissue

The 2019 DAN/R. W. “Bill” Hamilton Grant was awarded to Jens-Christian Meiners, Ph.D., of the University of Michigan. His project focuses on exploring spinal cord decompression sickness (SC-DCS) and the dynamics of gas bubble formation. This study will involve compressing and rapidly decompressing spinal cord tissue to induce bubble formation inside magnetic resonance imaging (MRI) scanners to identify any tissue damage that may arise.


Daniel Popa, University of California San Diego Medical Center/Universidad Marista de Mérida

Hypoxia Signatures in Closed Circuit Rebreather Divers

The 2018 DAN/R. W. “Bill” Hamilton Grant was awarded to Daniel Popa, M.D., Ph.D., an emergency medicine physician at the University of California San Diego Medical Center and an adjunct professor of clinical epidemiology and research methods at the Universidad Marista de Mérida. His study focused on the incidence of hypoxia in rebreather divers. Hypoxia, or insufficient oxygen to sustain bodily functions, is a hazard that closed-circuit rebreathers (CCRs) can experience when failures occur with their equipment.


Virginie Papadopoulou, Ph.D. University of North Carolina

Improving Decompression Science: Redefining Decompression Modeling

The 2017 DAN/R. W. “Bill” Hamilton Grant was awarded to Dr. Papadopoulou, who has a background in physics and bioengineering. She is a postdoctoral research associate in the Dayton Lab at the University of North Carolina at Chapel Hill, where her primary research addresses ultrasound imaging and cancer therapy using special formulations of microbubble contrast agents. Since receiving the Hamilton grant to support her research on improving decompression science by redefining decompression modeling to limit decompression stress, Dr. Papadopoulou has become a valued collaborator for DAN. She has advanced this initial grant into a multiyear research project, which is now also funded by the Office of Naval Research (ONR).

Ingrid Eftedal, Ph.D. Norwegian University of Science and Technology

Occupational Saturation Divers on the Norwegian Continental Shelf

The 2016 DAN/R. W. “Bill” Hamilton Grant Recipient was awarded to
Dr. Eftedal, who is an experienced dive medicine researcher with a background in biophysics and molecular biology. She is currently the principal investigator for a project titled Fitness to Dive – A Translational Approach To Physiological Challenges In The Hyperbaric Working Environment. The aim of Dr. Eftedal’s current research is to achieve an improved understanding of the immune system’s role in reactions and acclimatization to diving. Dr. Eftedal used the Hamilton grant to support a study on occupational saturation divers on the Norwegian continental shelf. The results of her study will provide information that may be applied to prepare divers and protect them from injury, which closely aligns with DAN’s mission to advance diving science and promote dive safety.

We are excited to announce a partnership between Global Underwater Explorers (GUE) and Scuba.Digital, the #1 Online Dive Show.

Scuba.Digital is hosted on one of the world’s best online event platforms and aims to become the World’s #1 Online Dive Show. With more than 200 exhibitors including Aggressor Adventures, WWDS, Blue O Two, Fourth Element, Divesoft, and many more, Scuba.Digital will bring divers and dive businesses from around the globe together. A program of speakers on the main stage and in our breakout sessions, a networking area and the expo booths, there is something for every diver, free diver or snorkeller.

Jason from Scuba.Digital said: “I feel that GUE are a good fit with Scuba.Digital. They are a non-profit organization that really cares about our oceans and helps people to explore the oceans with the right training in order to conserve what we have.”

Together GUE and Scuba.Digital will be able to bring more speakers with more information not only about diving, freediving or snorkelling but also about the current situation regarding COVID-19, it’s impact on how we partake in these water sports safely and also how we travel to get to the wonderful places we want to go. When will it be safe? What protections are there? Is my money safe? Together we can help the world of divers, free divers and snorkellers get back their confidence to return to the water.

Jason said: “We believe that the partnership between Scuba.Digital and GUE will bring benefits to both our organizations but most importantly to the scuba and free-diving communities themselves. In these times, an online event means that we can get the information we need direct from the owners of the dive resorts, liveaboards or manufacturers.”

Purchase your GUE ticket to the show for just $10.

We would like to Scuba.Digital for including us in their event!
