She received a bachelor of science degree in sport and physiological science at the University of Leeds in England, which developed her interest in extreme environmental physiology and sports biomechanics. She stayed at Leeds for a master\u2019s degree in nutrition, with her research project focusing on the interaction of nutrition and exercise.&nbsp;<\/p>\n\n\n\n<p>Her interest in the effects of extreme environments on the human body, combined with a love for diving, led her to move to Perth to pursue a PhD in health science, focusing on decompression bubbles in recreational scuba divers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-beth-what-is-your-phd-about\"><strong>Beth, what is your PhD about?<\/strong><\/h3>\n\n\n\n<p>My PhD focuses on venous gas emboli (VGE), which are bubbles that can form in the blood after diving. These bubbles often go unnoticed and are considered an indicator of decompression stress.&nbsp;<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"450\" height=\"600\" src=\"https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_124_Researcher-450x600-1.webp\" alt=\"Jones monitors bubbles in recreational divers.\" class=\"wp-image-30343\" srcset=\"https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_124_Researcher-450x600-1.webp 450w, https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_124_Researcher-450x600-1-270x360.webp 270w, https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_124_Researcher-450x600-1-9x12.webp 9w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><figcaption class=\"wp-element-caption\">Jones monitors bubbles in recreational divers. \u00a9 courtesy Beth Jones<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p>While not directly related, higher bubble loads have been linked to an increased risk of decompression sickness (DCS). In certain individuals, such as those with a patent&nbsp;foramen ovale (PFO), these formed bubbles can move from the venous circulatory system, where the lungs normally filter them out,&nbsp;to the arterial bloodstream, resulting in bubbles heading to the peripheral tissues.<\/p>\n\n\n\n<p>My research aims to develop a predictive model using real-world recreational dives to estimate bubble load based on nitrogen tissue uptake. My goal is to improve recreational dive safety by informing divers of their potential risk of high bubble loads after a dive.&nbsp;<\/p>\n\n\n\n<p>I\u2019m currently collecting dive profile data and monitoring for VGE using ultrasound to image the heart after recreational dives. Perth has an incredible dive community, which has made recruiting participants one of the easiest parts of my PhD. It has been great to interact with local dive groups and see how my research can help the dive community.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\" id=\"h-aren-leishman\">AREN LEISHMAN<\/h2>\n\n\n\n<p>Leishman has been a passionate scuba diver since he was 16 years old. He became a technical diver while completing his bachelor of advanced science degree in physics at Curtin University. His professional background in software development and embedded electronics along with his passion for developing electronics for diving caught Buzzacott\u2019s attention.&nbsp;<\/p>\n\n\n\n<p>Leishman completed an honors project using the modeling and mathematical background from his physics degree to analyze the impacts of high altitude on existing decompression models. He updated the R scuba package \u2014 a tool for performing theoretical calculations related to scuba diving \u2014 with the capabilities to model rebreather diving and altitude diving. He is now working on a PhD in health science, focusing on the cardiac impacts of diving.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"450\" height=\"300\" src=\"https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_126_Researcher-450x300-1.webp\" alt=\"Leishman perches in the entrance to Tommy Grahams Cave\" class=\"wp-image-30345\" srcset=\"https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_126_Researcher-450x300-1.webp 450w, https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_126_Researcher-450x300-1-360x240.webp 360w, https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_126_Researcher-450x300-1-18x12.webp 18w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><figcaption class=\"wp-element-caption\">Leishman perches in the entrance to Tommy Grahams Cave in Western Australia.\n \u00a9 Courtesy Neal Antoncich<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-aren-what-is-your-phd-about\"><strong>Aren, what is your PhD about?<\/strong><\/h3>\n\n\n\n<p>My PhD is focused on answering the questions that statistics in several DAN annual dive reports have raised, such as why so many divers die due to cardiac events. Cardiac events are a major contributor to fatalities, and fundamental research on exactly how the strains of diving affect the heart is rare.<\/p>\n\n\n\n<p>I plan to answer this question by exercising recreational divers at a controlled rate in a pool and in a hyperbaric chamber. Placing divers in an environment that closely represents real diving \u2014 including immersion, pressure, breathing mix, and workload \u2014 we have a unique opportunity to investigate physiological changes as they happen.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"450\" height=\"300\" src=\"https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_127_Researcher-450x300-1.webp\" alt=\"Leishman encounters a octopus\" class=\"wp-image-30346\" srcset=\"https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_127_Researcher-450x300-1.webp 450w, https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_127_Researcher-450x300-1-360x240.webp 360w, https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_127_Researcher-450x300-1-18x12.webp 18w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><figcaption class=\"wp-element-caption\">Leishman encounters a curious octopus at Rye Pier in Melbourne, Australia. \u00a9 Courtesy Bianca Fristad<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"450\" height=\"300\" src=\"https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_128_Researcher-450x300-1.webp\" alt=\"Jones presents at Oztek 2025.\" class=\"wp-image-30347\" srcset=\"https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_128_Researcher-450x300-1.webp 450w, https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_128_Researcher-450x300-1-360x240.webp 360w, https:\/\/world.dan.org\/wp-content\/uploads\/2025\/05\/Q2_128_Researcher-450x300-1-18x12.webp 18w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><figcaption class=\"wp-element-caption\">Jones presents at Oztek 2025. \u00a9 courtesy Beth Jones<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-both-of-you-are-working-with-an-interdisciplinary-network-in-perth-who-else-is-involved-in-this-work-and-how-does-it-impact-your-projects\"><strong>Both of you are working with an interdisciplinary network in Perth.

His background in the field allowed him to identify the skills needed when piecing together this highly diverse and interdisciplinary team.&nbsp;<\/p>\n\n\n\n<p>Luke Haseler, PhD, is a professor at Curtin University who focuses on cardiac and muscle imaging and how exercise impacts the heart\u2019s ability to function. His expertise enables us to use the cutting edge of cardiac measurement to get the most data out of every session in the hyperbaric chamber.<\/p>\n\n\n\n<p>Kagan Ducker, PhD, an associate professor at Curtin, is a sport, exercise, and health physiologist whose focus is enhancing athletic performance and studying exercise and physical activity in extreme environments. His knowledge of the physiological changes that can occur during extreme environmental exposures and of collecting data in these types of environments make him a valuable asset to this research group.&nbsp;<\/p>\n\n\n\n<p>Anna Scheer, PhD, is a physiotherapist and researcher who has worked with Luke on the impacts of immersion on cardiac function, focusing on how it can be used as a treatment for cardiovascular disease. Her experience in cardiac health has helped with the challenges associated with working with study participants while immersed in water.&nbsp;<\/p>\n\n\n\n<p>The work would not be possible without the generous support from Dr. Neil Banham, Dr. Ian Gawthrope, and the incredible team at the Fiona Stanley Hyperbaric Medicine Unit. They have always been willing to do whatever they can to support our research, enable opportunities for data collection, and address any questions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-do-you-hope-to-get-from-the-experiments-and-how-could-they-benefit-the-dive-community\"><strong>What do you hope to get from the experiments, and how could they benefit the dive community?<\/strong><\/h2>\n\n\n\n<p>Through cardiac research, we hope to better understand how diving affects the heart and what risk factors could explain the large number of cardiac fatalities in diving. The aim is to develop more specific predive screening recommendations and identify who may be more at risk so they can take appropriate precautions.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\" id=\"h-beth-you-were-an-intern-at-dan-in-2022-how-has-the-dan-internship-helped-you\"><strong>Beth, you were an intern at DAN in 2022.

The workshops on dive safety, data collection methods, ultrasound techniques, ongoing dive research, and dive equipment maintenance deepened my understanding of the field. The opportunity to visit other research institutes, hyperbaric chambers, and dive companies was also a fantastic experience.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-your-favorite-dive-or-site\"><strong>What is your favorite dive or site?<\/strong><\/h2>\n\n\n\n<p><strong>Leishman: <\/strong>My favorite dive is Busselton Jetty, south of Perth. It\u2019s a fantastic dive filled with marine life and underwater sculptures. It\u2019s in a wonderful spot for weather and visibility. You can see everything from stingrays to wobbegong sharks, nudibranchs, cuttlefish, and octopuses. I love going there and just floating, watching the world go by.<\/p>\n\n\n\n<p><strong>Jones: <\/strong>My favorite dives are often the ones with my family or when something unexpected happens (in a good way). One dive that stands out was off the eastern coast of Bali during the offseason. With no crowds around, it was just me and a local divemaster heading out on a small boat to a reef about 3.1 miles (5 kilometers) offshore. I had no expectations other than a relaxing dive filled with marine life.&nbsp;<\/p>\n\n\n\n<p>We descended into crystal-clear waters, where a long, sloping reef appeared, full of beautiful corals and an incredible diversity of fish. We saw bamboo sharks, sea snakes, octopuses, and a lot more.&nbsp;<\/p>\n\n\n\n<p>About 30 minutes into the dive I heard my divemaster laughing and shouting through his regulator and pointing at something. I turned and saw one of the ugliest and most graceful creatures I have ever seen. It was a <em>Mola<\/em> <em>mola<\/em> (ocean sunfish), and my very happy divemaster said they are a rare sight, especially at that time of year.&nbsp;<\/p>\n\n\n\n<p>That\u2019s what I love about diving: always seeing something new and never knowing what the ocean will show you.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-text-color has-dan-light-gray-color has-alpha-channel-opacity has-dan-light-gray-background-color has-background is-style-wide\"\/>\n\n\n\n<p class=\"has-small-font-size\">\u00a9&nbsp;<em>Alert Diver<\/em>&nbsp;\u2013 Q2 2025<\/p>\n\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>In 2021 Peter Buzzacott, PhD, of\u00a0 Curtin University in Perth, Australia, received DAN\u2019s Alfred Bove Research Grant for Cardiac Health in Scuba Diving.
