Chris Batich


Chris Batich obtained a Ph.D. in chemistry from Rutgers University, did a post-doc in at the University of Basel in Switzerland, and then spent seven years at the DuPont Central Research Department before coming to UF in 1980.  He has been involved in research for applications of materials to biomedical devices in numerous collaborative projects with the UF Health Center.  From 1997 until 2002 he was the founding director of the graduate Biomedical Engineering Program.  From 2008 until 2010 he was founding associate director and chief operating officer of the new Clinical and Translational Science Institute (CTSI) at UF.  Batich is a joint member of the UF BME Department as well as a professor in the Materials Science and Engineering Department. 

He has published about 160 peer-reviewed papers and is an inventor or co-inventor on 70 issued patents which were developed while at UF.  The most commercially significant technology is an advanced wound dressing called “Bioguard” which kills bacteria on contact with no active release agent.  It is now the standard dressing in the UF Burn Unit.  While at DuPont and UF, Batich has worked with surface modification and analysis of polymeric materials as well as drug delivery and preventing neurodegeneration. 

In 2020, Batich was elected to the Florida Inventors Hall of Fame. In 2023 he retired from the university and was given Emeritus Professor status.

Dr. Bremner moved to Emory from Yale in November of 2000 where he spent the first 12 years of his career.

Dr. Bremner’s research has used neuroimaging and neurobiology measures to study the neural correlates and neurobiology of posttraumatic stress disorder (PTSD) related to combat and childhood abuse, as well as the related area of depression. His more recent work is expanding to look at the relationship between brain, behavior, and physical health including studies of heart disease and the brain.


Dr. Bremner has worked continuously throughout his career as a physician scientist, with the support of funding from two successive VA Career Development Awards, VA Merit Review, NIH, DOD, and various private sources. His research included studies of the neurobiology and assessment of PTSD, hippocampus and memory in PTSD and depression, neural correlates of declarative memory and traumatic remembrance in PTSD, PET measurement of neuroreceptor binding in mood and anxiety disorders, neural correlates of myocardial ischemia, and the effects of treatments on the  brain including psychotropic medication, mindfulness training, and Vagal Nerve Stimulation (VNS).

Scientific Advisor 

Marcus Elliott has over a decade of experience in process engineering and quality control, primarily for Saint-Gobain, a fortune 500 company and global leader in innovative material manufacturing. Elliott was one of Evren's first employees, joining the team in August of 2019 as a Quality and Project Manager. Elliott's role quickly expanded as he demonstrated a deep understanding of taVNS as a PTSD treatment, clinical trials, and grant proposals. He has since designed and constructed multiple prototype devices, was co-PI for our pilot trial and supported multiple NIH and DoD grant proposals, resulting in nearly $500K awarded to date. Elliott previously served as VP of Research & Development and will continue to work with Evren in an advisory role. 

Elliott holds a BS in Engineering from Alfred University and a Green Belt certification in Saint-Gobain's World Class Manufacturing (WCM) system. This award-winning WCM system is a blend of Six Sigma, Toyota TPM, Lean, and 5S.
