A Tennessee native, Dr. Partain was born in Memphis and later graduated from high school in Clarksville. He then received his BS in nuclear engineering from the University of Tennessee, his MS and PhD in nuclear engineering from Purdue University and his MD from Washington University. He completed his residency training in diagnostic radiology and nuclear medicine at the University of North Carolina. Dr. Partain was clinically trained and certified in diagnostic radiology and nuclear radiology by the American Board of Radiology (ABR) and the American Board of Nuclear Medicine. Throughout his career, Dr. Partain contributed to the growth of Vanderbilt Radiology and received many academic and research accolades across the specialty through various associations. During his time leading the department, clinical studies increased from 180,000 to 260,000 cases per year, emerging technological imaging equipment expanded the department’s capabilities, and units for angiography and fluoroscopy were added to the tool kit. The department also expanded its footprint with outpatient imaging in Nashville, Bedford County and more. Research continued to expand with continued growth in scientific findings and millions in grant funding for radiopharmaceuticals, functional MRI, nuclear medicine, X-ray, ultrasound and more. Dr. Partain is celebrated for being instrumental in bringing the first MRI and PET/CT machines to the Medical Center. His efforts helped build Vanderbilt Radiology’s prestige in the world of academics and research both nationally and internationally. His society affiliations included the American College of Radiology, the American College of Nuclear Medicine, and the International Society of Magnetic Resonance in Medicine (ISMRM). He served as president of the Radiological Research Alliance of the Association of Academic Radiologists and has held executive roles as a member of many radiological society boards. Dr. Partain was editor-in-chief of the Journal of Magnetic Resonance Imaging from 2000 to 2013 and a member of the editorial boards of Magnetic Resonance in Medicine, Magnetic Resonance Imaging, the American Journal of Roentgenology, Academic Radiology, the Journal of Nuclear Medicine and Investigative Radiology. He has authored/co-authored/edited six textbooks, including one of the first comprehensive textbooks on MRI, “Nuclear Magnetic Resonance (NMR) Imaging.” Dr. Partain has also authored/co-authored/edited approximately 100-plus book chapters and 200-plus journal articles. In 2000, Dr. Partain received the Distinguished Service Award from the ABR. In 2014, he received the Distinguished Service Award from the ISMRM.

Closing health workforce gaps for emergency response: the Western Pacific steps up
Over 100 health emergency experts from 56 institutions across 21 countries in the World Health Organization (WHO) Western Pacific Region who are part of the Global Outbreak Alert and Response Network (GOARN) concluded their annual regional partners’ meeting with a commitment to bridge gaps in emergency workforce capacities and advance regional emergency readiness and resilience.Co-hosted by WHO and the Korea Disease Control and Prevention Agency in the Republic of Korea, the two-day event aimed to strengthen the Region’s collective ability to detect, prepare for and respond to health emergencies.Partners mapped capacities and priority technical gaps across the Region — including cybersecurity and critical infrastructure resilience; water, sanitation and hygiene (WASH) and environmental health; biological emergencies, nuclear emergencies, and nuclear and radiological security.The result: a renewed commitment to close these gaps by working together through shared expertise and coordinated action. Advancing the Global Health Emergency CorpsReflective of regional solidarity and partnerships in action, GOARN – which is coordinated globally by WHO - enables a stronger, better-connected emergency health workforce that is ready to surge wherever and whenever requested by WHO Member States.This year alone, GOARN partners across the Western Pacific have supported nine experts on six missions - from measles outbreaks in Viet Nam to HIV outbreak response in Fiji - providing surge support in epidemiology, surveillance and clinical case management.Photo: Participants at the Global Alert and Response Network (GOARN) Partners Meeting 2026. Credit: KDCA/Shin Dong Myoung“GOARN partners across the Western Pacific and globally have repeatedly demonstrated the power of what we can do collectively, when we join forces, share expertise and build on each other’s strengths,” noted Dr Gina Samaan, WHO Regional Emergency Director for the Western Pacific, in her opening remarks at the gathering. “Let us continue to forge long-term partnerships grounded in mutual respect that will protect the Region for generations to come. We are smarter, faster and infinitely stronger when we work together,” she added.Reiterating Dr Samaan's call, Dr Seung-kwan Lim, Commissioner of the Korea Disease Control and Prevention Agency, emphasized the value of GOARN: “The Republic of Korea is pleased to stand alongside our regional partners in building an emergency workforce that is ready and resilient. GOARN turns national expertise into regional readiness - catalysing national strengths into collective resilience.”GOARN advances the Global Health Security Action Framework (GHEC) initiative by “convening, connecting and capacitating” regional leaders and surge workforce – “the three Cs”. Years of GOARN leadership and outbreak response training programmes have cultivated a deep bench of fit-for-purpose, seasoned outbreak response experts and forged an alumni network of emergency leaders worldwide. The Western Pacific network alone has now grown to 94 partner institutions across 19 countries. Photo: Participants at the Global Alert and Response Network (GOARN) Partners Meeting 2026. Credit: KDCA/Shin Dong Myoung Putting partnerships into practiceDuring the Regional Partners’ Meeting, health experts identified and catalogued the technical expertise currently available across the Western Pacific Region, so that the right skills could be better matched quickly to needs wherever emergencies occur.Three priority areas emerged for further strengthening:Cybersecurity and critical infrastructure resilience - protecting essential systems, including healthcare networks, from digital disruptions.Water, sanitation and hygiene (WASH) and environmental health - reflecting the ongoing nexus between climate change and health.Biological emergencies, nuclear emergencies, and nuclear and radiological security - requiring specialized technical capability that remains limited across many national response systems.Meeting participants reaffirmed their commitment to strengthening workforce capacities in the Region, with a particular focus on these three areas, and to working collectively to better prepare the Western Pacific for the next health emergency.Photo: Dr Gina Samaan, WHO Regional Emergency Director for the Western Pacific, delivers opening remarks at the Global Alert and Response Network (GOARN) Partners Meeting 2026. Credit: KDCA/Shin Dong Myoung“GOARN is truly turning preparedness into action - giving our Region the surge capacity it needs for fast, coordinated response when it matters most - and building more resilient health systems along the way,” said Dr Samaan. “As health emergencies mount in this age of permacrisis, emergency preparedness and response must be woven into the fabric of health. This is not an option, but an imperative as we seek to achieve health for all.”____ About GOARNThe Global Outbreak Alert and Response Network (GOARN), coordinated by the World Health Organization since 2000, strengthens global health security by advancing preparedness for and response to public health emergencies. The network brings together more than 390 institutions, including national public health agencies, technical organizations and nongovernmental partners, to support coordinated international action during outbreaks and other health emergencies. There are 94 GOARN partners in the Western Pacific Region (as of August 2026), accounting for approximately 25% of global partners.
