Timothy B. Meier

Dr. Timothy B. Meier is a Professor at the Medical College of Wisconsin, holding dual appointments in the Departments of Neurosurgery and Biomedical Engineering. He is a core member of the Neuroscience Research Center, Brain Injury Research Program, and Wisconsin Institute of NeuroScience (WINS). With a PhD in Neuroscience from the University of Wisconsin-Madison, he specializes in neuroimaging, biomarker discovery, and neurochemical pathways related to traumatic brain injury (TBI) and concussion.

• Education
  • B.S. Psychology, University of Illinois at Urbana-Champaign
  • Ph.D. Neuroscience Training Program, University of Wisconsin-Madison

Dr. Meier's research focuses on:

• Neuroimaging (fMRI, DTI, susceptibility mapping) to characterize structural and functional brain changes post-concussion
• Biomarker development for TBI diagnosis and recovery tracking, including blood-based and kynurenine pathway markers
• Long-term effects of repetitive head impacts in athletes across developmental stages
• Neuroinflammatory mechanisms in TBI and their psychiatric comorbidities
• Machine learning applications for concussion assessment and outcome prediction

His recent publications demonstrate expertise in:

• Multimodal neuroimaging of pediatric and sports-related TBI
• Linking cerebrovascular dysfunction to chronic TBI outcomes
• Advancing standardized diagnostic protocols for concussion
• Exploring sex-based hormonal influences on recovery
• Developing objective gait and balance assessments for return-to-play decisions
• Investigating kynurenine pathway metabolites in TBI and depression

Scientific Awards:

• Graduation with Distinction in Psychology (University of Illinois)
• National Research Service Award T32-GM007507
• UW Vilas Conference Presentation Funding

Dr. Meier serves as a Co-Investigator in major grants including the NCAA-DoD CARE Consortium ($4.99M) and GE Healthcare/NFL concussion imaging studies. His work bridges clinical neurosurgery, basic neuroscience, and data science to advance TBI diagnostics and recovery protocols.
