Fellow, California Academy of Sciences

 

Dr. Lewin is an internationally recognized expert in the practice of emergency medicine and wilderness medicine. He has served as doctor on major scientific expeditions sponsored by the American Museum of Natural History, the Field Museum, Kellogg Foundation and National Geographic funded scientific expeditions. He is the author of several book chapters in leading texts on wilderness medicine and is a regular contributor to major, peer-reviewed publications such as Annals of Emergency Medicine, Lancet, Journal of Emergency Medicine and Wilderness and Environmental Medicine, among others. He is a life-member of the Wilderness Medicine Society and in 2010 became a Fellow of the American College of Emergency Physicians in recognition of his academic accomplishments in the field. He was director of Emergency Medicine Research at UCSF from 2003 until 2009. He is Associate Editor of Updates in Emergency Medicine. He is a popular invited speaker on his research and clinical interests in wilderness and pre-hospital medicine worldwide having lecturing on a regular basis at national and international meetings in Europe and Asia. Since 2008, he has been the California Academy of Sciences emergency medicine liaison to UCSF. He has played an active role in developing and testing protocols for the safe handling and first aid of Academy and Aquarium employees potentially exposed to venomous animals housed on Academy grounds and on display to the public. His current research is focused on the global expansion of treatments for snakebite and other neurotoxins that disable or kill by paralysis.

 

Stephen Paul Samuel MBBS, MSc, PhD
Nanomedicine and Molecular Imaging Group
Department of Clinical Medicine
Trinity College Dublin

Dr. Stephen Paul Samuel is a key collaborator with the Center for Exploration and Travel Health in research dedicated to combating death and disability from neurotoxic snakebite. He received his MBBS at P.S.G Institute of Medical Sciences and Research, Coimbatore, Tamil Nadu, India. He worked in various clinical specialities including Accident and Emergency, General Surgery, Internal Medicine and General Practice. He then went on to do his Masters (Molecular Medicine) and subsequently completed his PhD (Clinical Medicine); both from Trinity College Dublin, Ireland. He has been working in Nanomedicine and Molecular Imaging group, Department of Clinical Medicine since 2012. His research interest has been focussed on the interactions of engineered nanoparticles including quantum dots with components of human microvasculature: plasma, platelets and endothelial cells.

 

Toby O. Salz, MD

Board Certified in Emergency Medicine

 

Dr. Toby Salz is a Board Certified Emergency physician with expertise in general emergency medicine, travel, expedition and disaster medicine. He is a graduate of Chicago Medical School and the Alameda County Medical Center, Highland General Hospital emergency medicine residency program affiliated with the University of California San Francisco School of Medicine. He has worked in a diversity of challenging environments such as Chiapas, Mexico, Ecuador and the U.A.E.'s regional Rashid Trauma Center located in Dubai. Most recently, he served as Medical Director of the Emergency Department and ICU of Hôpital de L'Universite D'Etat D'Haïti during two medical missions to post-Earthquake Haiti. Dr salz remains committed to the well-being of Haitians and to supporting quality healthcare in Haiti.

CETH Snakebite Project

Snakebite is arguably the most neglected of neglected tropical diseases, with an estimated 5,000,000 bites per year and mortality approaching that of AIDS in some countries. Teaming up with colleagues from UCSF and India, we are taking a completely new approach to the treatment of bites by snakes that disable and kill by paralysis (e.g. Cobra, sea snake, taipan). We are reformulating heat-stable, inexpensive drugs suspected to be effective against venoms that paralyse by interrupting transmission between muscle and nerve. Preliminary data from a human study suggest this approach will be effective and we are initiating collaborations to bring these potentially life-saving drugs where they are needed most.
