Biography

    Joy S. Reidenberg, Ph.D. is a Professor at the Icahn School of Medicine at Mount Sinai in New York City. Dr. Reidenberg received a B.A. in 1983 from Cornell University's College of Arts and Sciences. She earned her M.Phil. in 1985 and her Ph.D. in 1988 in Anatomy from Mount Sinai’s Graduate Program in Biomedical Sciences in New York. Dr. Reidenberg has also held appointments as a Guest Investigator at the Woods Hole Oceanographic Institution, and as an Associate Scientist at the National Museum of Natural History of the Smithsonian Institution. Dr. Reidenberg is a biomedical research scientist who studies comparative anatomy. She has examined a large variety of animals ranging from insects to humans, but her particular fascination is with aquatic animals. Much of Dr. Reidenberg’s recent work is focused on how animals adapt to environmental extremes. Current research is focused on the anatomy of whales, dolphins and porpoises, especially in understanding how they produce sounds and withstand the pressures of diving. Her anatomical research focuses on these animals as "natural experiments" from which we can learn about basic biomechanical relationships that affect all animals, including humans. Dr. Reidenberg is interested how these animals have evolved adaptations to solve problems we consider a survival challenge in humans. She hopes to learn from nature and develop protective/preventive technologies or new medical treatments for injuries and diseases based upon mimicking these adaptations. Dr. Reidenberg work has been federally funded by: Office of Naval Research, Department of Defense, National Oceanic Partnership Program, and National Oceanic and Atmospheric Administration. Her research and scientific expertise has been featured in many science and educational television documentaries that have aired both nationally and internationally on PBS (USA), BBC (worldwide), National Geographic (worldwide, including Israel), NatGeo Wild (USA), Discovery Channel (USA & Canada), Channel 4 (UK), SBS (Australia), etc. Dr. Reidenberg’s most recent involvement is as the comparative anatomist for 18 episodes of the natural history documentary series Inside Nature’s Giants that examines the anatomy, function, and evolution of large animals. It has aired world-wide on National Geographic International, and in the US on NatGeo Wild and PBS. Inside Nature’s Giants has been recognized with many awards, including: British Academy of Film and Television Arts Award (the BAFTA is the UK equivalent of an Emmy Award), World Gold Medal Television and Film Award, Thompson Reuters Zoological Record Award for Communicating Zoology, Broadcast Award, and Royal Television Society Award. Dr. Reidenberg just completed a new 4-part documentary series that aired on PBS (USA) called Sex in the Wild, and on Channel 4 (UK) under the title Born in the Wild. Dr. Reidenberg has been featured twice in the British journal Nature: “Truly Gross Anatomy” (3 April 2008) whichdiscussed how she dives into whale carcasses to study their anatomy, and “Q&A: Prime Time dissection with Joy Reidenberg” (24 June 2010) which focused on her outreach teaching of anatomy through television. She was also interviewed in O, the Oprah Magazine in a full page spread on her unusual career in anatomy called “Inside the World of Anatomist Joy Reidenberg” (April 2011) and in the New York Times - Science Times, “From Inside Lions and Leviathans, Anatomist Builds a Following” (February 2012). Teaching is a passion for Dr. Reidenberg. Courses she has taught to medical and graduate students include: Structures, Human Gross Anatomy, Histology, Anatomic Radiology, and electives in Comparative Anatomy and Creative Visions, and she participates in several anatomy courses for surgeons, allied health professionals, and fitness instructors. Her energies in this regard have earned her teaching awards both within her institution and nationwide. She was awarded the highest national prize in her field (The Basmajian Award) by the American Association of Anatomists for her excellence in both teaching and research.

Research

Comparative anatomy of the upper respiratory tract in a wide range of mammals

Research in this laboratory examines the comparative anatomy, development, and evolution of the mammalian upper respiratory tract, particularly factors that may affect breathing, swallowing, and vocalizing abilities, or clinical disorders.

Our research focuses on upper respiratory tract anatomy in a wide range of mammals, with particular emphasis on cetaceans (whales, dolphins, and porpoises). Cetaceans are studied as a "natural experiment" to understand the evolutionary forces selecting for a highly modified upper respiratory tract adapted for an aquatic existence. Our current project is developing an atlas of mysticete (baleen whale) anatomy. As an extension of this interest, investigations are in progress to examine the controversial role of the cetacean larynx in sound production for communication or echolocation. Techniques include comparative dissection (including fieldwork at site of beach-stranded whale), histology, and imaging by CT or MRI. Our important findings in comparative anatomy include:

  • discovery of a vocal fold homolog in whales previously thought to lack this,
  • identification of the lack of posterior protection of the human larynx compared with other mammals and resulting exposure of the airway to incursions from the digestive tract,
  • use of MRI and CT scans to appreciate hyo-laryngeal positional asymmetries in toothed whales that correlate with functional and behavioral asymmetries,
  • impact of slow vs. sudden pressure changes on tissues of the respiratory tract in diving mammals.
  • New insights into the origin of human clinico-pathologies related to the upper respiratory tract include defining the lack of posterior laryngeal protection from gastric juices as the major anatomical cause of respiratory tract insult secondary to Gastro-Esophageal Reflux Disease (GERD).

    Future directions we would like to take our research program include:

  • Comparative Anatomy: Investigate and compare respiratory tissue response to pressure change from natural (diving) and artificial (explosion) causes. Determine how diving marine mammals mitigate for decompression sickness. Understand how marine mammal lungs can vary compliance. Explore sound production/transfer mechanisms by aquatic mammals in air vs. water.
  • Development: Elucidate temporal/spatial relationships of branchial arches and normal and pathological development of skull/soft tissue relationships.
  • Human Clinico-Pathologies: Examine animals exhibiting posterior laryngeal protection (e.g., ruminants), create a similar artificial barrier (surgical or prosthesis), and develop an animal model of Gastro-Esophageal Reflux Disease (GERD) in which to test this barrier. If model is successful, further develop in collaboration with surgeons for human patients with GERD.
  • Evolution: Reconstruct evolutionary trajectories of aerodigestive tract.
