CAPT Rodgers is currently Chair of the Scientist Professional Advisory Committee, which provides professional guidance to the Corps’  more than 300 doctoral-level officers.

Vice Chair: LCDR Jason Wilken


LCDR Jason Wilken commissioned into the Corps in 2012 as a CDC Epidemic Intelligence Service Officer, after which he joined CDC's Career Epidemiology Field Officer (CEFO) program in CDC's Center for Preparedness and Response. Assigned as a CEFO to the California Department of Public Health (CDPH), LCDR Wilken builds capacity for disease surveillance and epidemiology, particularly in the fields of emergency preparedness, disaster response, and environmental and occupational epidemiology. LCDR Wilken has deployed for CDC responses to the Ebola virus disease outbreak in Liberia and Zika virus disease outbreak in American Samoa. He holds a Ph.D. in Biochemistry and Molecular Biology from the University of Nebraska Medical Center, an MPH in Epidemiology from Emory University, and is credentialed as an Emergency Operations Center Director by the state of California.

LCDR Wilken has previously served as the Chair of the Website Subcommittee and as the SciPAC COF Liaison, and has served on the PHS Regional Incident Support Team 9 since 2014.

Immediate Past Chairperson: CAPT Jennifer Thomas


CAPT Jennifer (Jennie) Thomas is the Lead of the Biological Rapid Response and Advanced Technology Laboratory in the Laboratory Preparedness and Response Branch of the Division of Preparedness and Emerging Infections in the National Center for Emerging and Zoonotic Infectious Diseases at CDC. Prior to joining the BRRAT Laboratory, CAPT Thomas was a Microbiologist in the CDC Meningitis Laboratory (2007-2016). While there, she developed and led validation of real-time PCR assays for detection of Neisseria meningitidis species and 6 Haemophilus influenzae serotypes. She worked closely with WHO-AFRO and ministries of health to transfer these technologies and to help establish real-time PCR based bacterial meningitis surveillance networks in the least developed countries in West and Central Africa. She continued to support introduction and evaluation of a new, epidemic-ending meningitis vaccine in the “African Meningitis Belt” through her laboratory leadership in the Surveillance in Central Africa (SURVAC) and MenAfriNet Projects. CAPT Thomas’s public health emergency response work includes deployment for CDC to its Influenza Diagnostics Team for the H1N1 Pandemic Response (2009); to Mali for Ebola response (2014); to Niger and Oregon for meningitis outbreaks (2015-2016); and as an agency-level leader in the Zika response (2016).  CAPT Thomas has extensive laboratory and public health emergency response leadership and is passionate about laboratory capacity building via development of cutting-edge pathogen detection capabilities, mentoring, and preparedness through strong public health partnerships.

CAPT Thomas completed her B.A. in French at Agnes Scott College in Decatur, Georgia (1995).  She earned her Ph.D. in microbiology and molecular genetics and completed her dissertation on the “Genetic Basis for Nongroupable Neisseria meningitidis” at Emory University in Atlanta, Georgia (1997-2002). After graduation, she completed a postdoctoral fellowship at Emory University where she studied genetic regulation of virulence in enteropathogenic E. coli (2002-2004). She was an Adjunct Professor at Edison College and a Visiting Instructor at Florida Gulf Coast University in Fort Myers, Florida, where she was also a Research Associate investigating inhibition of influenza virus binding to mammalian cells (2004-2006).  In 2006, CAPT Thomas joined CDC as a Microbiologist in the Poxvirus Laboratory to study monkeypox virus virulence factor regulation. She commissioned into the United States Public Health Service in 2007. She served on PHS Rapid Deployment Force 3 for seven years, deploying for Operation Foothold (2011), Hurricane Irene (2011), and Major Flooding Louisiana (2016). CAPT Thomas has been actively involved in SciPAC, including as a Recruitment, Readiness, and Retention Subcommittee member (2014-2015), the Science Subcommittee Co-chair (2012-2014), and as Category Day Subcommittee Social Team Lead (2014-2015). She became a SciPAC Voting Member in 2015 and served as Co-Chair of the Mentoring Subcommittee (2015-2016) and Chair of the Policy (2016-2017) and the Rules and Membership (2017-2018) Subcommittees. She is the first laboratory scientist to serve as SciPAC Chair in over a decade.
