LCDR Xinzhi Zhang

2022_Xinzhi.jpgLCDR Xinzhi Zhang, MD, PhD, FACE, is the Chief of Health Inequities and Global Health Branch at the Center for Translation Research and Implementation Science at the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health (NIH). He has broad research interests that include clinical epidemiology, health services research, data science, health informatics, and their applications to promote health equity nationally and globally.

Before joining NHLBI, LCDR Zhang was a program director in the National Center for Advancing Translational Sciences (NCATS) Division of Clinical Innovation, where he managed a portfolio of Clinical and Translational Science Awards (CTSA), including overseeing the CTSA National Center for Data to Health (CD2H). During the COVID-19 pandemic, CD2H initiated National COVID Cohort Collaborative (N3C), the first-ever nationally centralized electronic medical record data openly accessible for the clinical and research community to use for studying COVID-19 and for identifying potential treatments. LCDR Zhang was the NCATS lead on rural health and health equity and Co-Chaired the NIH Rural Health Interest Group. He was also the lead for the diversity and re-entry research supplements program.

LCDR Zhang joined NIH in 2012 as a program director in the National Institute on Minority Health and Health Disparities’ Division of Extramural Scientific Programs where he provided leadership for scientific program development and project management on minority health and health disparities research. He spearheaded the development of research initiatives including Multilevel Chronic Disease Prevention, Simulation Modeling and System Science, Enhancing Diversity in Biomedical Data Science, and Social Determinants of Health Collection using the PhenX Toolkit.

Prior to that, LCDR Zhang had joined the National Center for Infectious Diseases’ Office of Surveillance at the Centers for Disease Control and Prevention (CDC) in 2003 as a Steven M. Teutsch Prevention Effectiveness Fellow. His pandemic preparedness tool, FluSurge, is widely recommended (e.g. by WHO/PAHO, Johns Hopkins University) and used (e.g., by STAT, countries like Spain) to estimate surges in demand for hospital-based services during the COVID-19 pandemic. From 2005 to 2012, he was an epidemiologist in CDC’s National Center for Chronic Disease Prevention and Health Promotion’s Division of Diabetes Translation and was instrumental in establishing the vision and eye health program at CDC.

LCDR Zhang has authored 4 papers for inclusion in CDC’s Morbidity and Mortality Weekly Report, 3 book chapters, and 70 articles published in peer-reviewed journals, including the Journal of the American Medical Association, the American Journal of Public Health, and the American Journal of Preventive Medicine. He is one of the editors of the 2021 textbook on The Science of Health Disparities Research. He also served as the interim Editor-in-Chief of journal Health Equity.

Throughout his career, LCDR Zhang has received many honors and awards from NIH, CDC, AHRQ, American Public Health Association, and Commissioned Corps of the U.S. Public Health Service, including 2 Presidential Unit Citations and 2 Outstanding Service Medals. LCDR Zhang received his M.D. from Peking Union Medical College in 1998 and his Ph.D. in health services administration from the University of Alabama at Birmingham in 2003. 


CDR Tegan Boehmer

2022_Boehmer.jpgCDR Tegan Boehmer, PhD, MPH, is a senior health scientist at the U.S. Centers for Disease Control and Prevention.  She earned a Ph.D. in Public Health Studies and M.P.H. in Epidemiology from Saint Louis University School of Public Health.  CDR Boehmer began her career at CDC in 2006 with the Epidemic Intelligence Service (EIS) program investigating infectious and occupational disease outbreaks at the Tri-County Health Department in Colorado.  After completing EIS, she held various scientific, response, and leadership positions within CDC’s National Center for Environmental Health (NCEH) from 2008 to 2020.  She advised the World Health Organization, Health Canada, and U.S. Environmental Protection Agency on the state of the science and guidelines for protecting people from harmful effects of air pollution and advanced federal partnerships with U.S. Department of Transportation and the National Park Service that resulted in resources to guide evidence-based decision making around transportation and trails and green space. As Chief of the Health Studies Branch, NCEH, she oversaw groundbreaking work to minimize the impact of environmental health disasters and emerging hazards. Notably, she secured $10M in 2017 hurricane recovery funding that resulted in several innovative programs to enhance disaster epidemiology and preparedness in affected jurisdictions. In 2020, CDR Boehmer transitioned to CDC’s Center for Surveillance, Epidemiology, and Laboratory Services where she serves as a Senior Health Scientist in the Public Health Informatics Office.

CDR Boehmer is a graduate of CDC’s Incident Manager Training and Development Program. She has held high-level leadership roles in CDC emergency responses for hurricanes (2017, 2018), lung injury associated with vaping (2019), and COVID-19 pandemic (2020–2022) and deployed with USPHS to support the Unaccompanied Children Mission (2021). CDR Boehmer has been on a near-continual deployment to CDC’S COVID-19 Response since March 2020 during which time she oversaw national laboratory and emergency department surveillance; development of CDC’s “big data” computing infrastructure; and evaluation, procurement, and analysis of novel healthcare data sources. In two years, CDR Boehmer co-authored 23 high-impact scientific publications (11 as a lead or senior author) that advanced COVID-19 epidemiology and informed U.S. and international guidelines for vaccine prioritization and national policy decisions related to vaccine adverse events.

CDR Boehmer has contributed substantially to SciPAC and Atlanta COA. During two terms as a SciPAC voting member, CDR Boehmer served as COF Liaison, Secretary, Website Subcommittee Chair, and Category Day Subcommittee Chair. After her second term ended in 2015, she continued to serve the USPHS and Scientist category by reviewing officer CVs and recruitment applications, serving on the SciPAC Rules and Membership Subcommittee, mentoring junior officers, and recruiting, supervising, and mentoring USPHS officers in the EIS program. CDR Boehmer currently serves on the Atlanta COA Executive Committee as the Events Planning Co-chair and previously coordinated multiple community service events. In addition to numerous USPHS awards, she has been honored with multiple agency awards including a 2021 individual honor award for Excellence in Surveillance and Health Monitoring for her exemplary leadership and scientific impact during the COVID-19 pandemic.
