Research Chemist
Viral and Rickettsial Diseases Department Infectious Diseases Directorate
Naval Medical Research Center
U.S. Department of Defense (DoD)
(Regular Government Employee)

 

Dr. Chao has had more than 15 years of experience in studying rickettsiae and rickettsial diseases with extensive experience in developing and evaluating O. tsutsugamushi vaccine candidates, diagnostics, genomics, proteomics, metabolomics, and biology in Leptrombidium mites, and murine models of scrub typhus, and surveillance studies of tick-borne rickettsiae in Asia, Central America and Africa. He began his career as a Biochemist to understand free radical-dependent cellular damages in cancer and aging. His career took a turn in 2002 when he joined the Rickettsial Diseases Department of the Naval Medical Research Center. Since 2002, he has been involved in research on rickettsial epidemiology, pathogenesis, and immunology as well as in the development and evaluation of rickettsial diagnostic assays and vaccine candidates. He has been a steering committee member of the DoD Rickettsial Diseases Research Program since 2007. Dr. Chao also served as a Deputy Research Coordinator of the Diagnostic Systems of Military Infectious Diseases Research Program from 2007 – 2018, focusing on the development of Food and Drug Administration approved field-deployable diagnostic assays for vector-borne diseases.

In His Own Words: “To provide a solution to the ever-expanding tick-borne diseases takes dedication, innovation, open-mindedness, and cross-discipline collaborations of scientists. The goal of such effort is to improve the prevention, diagnosis and treatment of tick-borne diseases. Studies designed to better understand the interactions among host-pathogen-vector as well as the impact of unprecedented shifts in both environmental conditions and the movement of humans will provide us tools to successfully impede disease transfers at the pathogen, vector and ecology level.”

Captain Scott J. Cooper, MMSc, PA-C

Senior Technical Advisor and Lead Officer for Medicare Hospital Health and Safety Regulations
Centers for Medicare and Medicaid Services (CMS)
U.S. Department of Health and Human Services
(Regular Government Employee)

 

Captain Cooper is a physician assistant (PA) officer in the United States Public Health Service (USPHS). Since 2003, he has been assigned to the CMS, where he is the senior technical advisor and the lead officer responsible for the Medicare health and safety regulations for the nation’s nearly 5,000 hospitals. During this time, he has been responsible for the publication of numerous national hospital rules aimed at improving patient safety and care, but which still allow hospitals the flexibility to employ evidence-based “best practices” in their efforts to provide higher quality patient care at a reasonable cost.

In 2013, Captain Cooper completed a long-term special assignment to the Commonwealth of the Northern Mariana Islands where he served as the first compliance officer and special advisor for the Commonwealth’s only hospital, which was struggling to address significant patient safety and quality of care issues. Additionally, Captain Cooper has over a decade of experience responding to various public health emergencies throughout the nation; most recently, he was part of the USPHS response to Hurricane Harvey in Texas and prior to that he served as the mission chief for a team that responded to a suicide epidemic on an Indian reservation in South Dakota in 2015.

In addition to being stationed with the Federal Bureau of Prisons early in his public health career, Captain Cooper also has extensive clinical experience working with patients in private sector hospitals, primarily in the specialty of cardiac surgery, with over 20 years of experience as a PA. He graduated from the Emory University School of Medicine Physician Assistant Program in 1996 with a Master of Medical Science degree.

In His Own Words: “Through my work at CMS, I have had the opportunity to become involved in many issues surrounding infection prevention and control. Part of that work has been looking at the potential use of antimicrobial stewardship programs to combat antimicrobial resistance and its dangers to public health. My participation in the federal steering committees for both the HHS Action Plan to Prevent Health Care-Associated Infections and the National Action Plan for Combating Antibiotic-Resistant Bacteria has made me keenly aware of the need for medical science and government to address emerging and growing infectious disease threats, including those where organisms have developed resistance to drugs that were once effective against them.

I believe that a coordinated and evidence-based approach to tick-borne disease (TBD) will be an important part of these larger efforts. I am encouraged by the fact that the Tick-Borne Disease Working Group has been established and believe that it is needed to address this specific area of infectious disease and public health. Since there appear to be areas of disagreement over tick-borne disease research, prevention, diagnosis, treatment, sequelae, etc., a working group focused on tick-borne disease is a crucial first step toward finding ways to effectively and safely care for patients living with TBD now and to eliminate the threat of living with TBD for those in the future.”
