Looking Into the Lungs

During medical school Peter Lindholm joined a laboratory researching aviation, space and underwater physiology, where he developed a passion for breath-hold dive physiology, about which he wrote his doctoral thesis. As one of the physicians for the Swedish Sports Diving Federation (SSDF), he was involved in developing breath-hold dive protocols and training the first instructors of competitive breath-hold diving. After clinical training as a radiologist, Lindholm moved to San Diego, California, where he leads a research group focused on dive physiology and dive medicine.

Michael Lombardi: Immersed in Science

FISHING AND BEING ON THE WATER with family while growing up influenced Michael Lombardi to study marine biology. He and a friend got certified to dive during his junior year of high school, thinking it would be a useful tool for his desired field. Lombardi had no idea what professional diving meant or where it would take him.
