Hayes's research appeared in a variety of scientific journals, most frequently in the Journal of Neurotrauma. Other important venues for their work included:

  • Journal of Neurotrauma
  • bioRxiv (Cold Spring Harbor Laboratory)
  • Annals of Neurology
  • Scientific Reports
  • Frontiers in Neurology

Their recent publications reflected studies on brain injury biomarkers, including investigations into sport-related concussion and brain injury in COVID-19 patients:

  • A Prospective Study of Acute Blood-Based Biomarkers for Sport-Related Concussion, 2020, Annals of Neurology
  • Blood Biomarkers for Detection of Brain Injury in COVID-19 Patients, 2020, Journal of Neurotrauma
  • Circulating GFAP and Iba-1 levels are associated with pathophysiological sequelae in the thalamus in a pig model of mild TBI, 2020, Scientific Reports
  • Acute Effects of Sport-Related Concussion on Serum Glial Fibrillary Acidic Protein, Ubiquitin C-Terminal Hydrolase L1, Total Tau, and Neurofilament Light Measured by a Multiplex Assay, 2020, Journal of Neurotrauma
  • Glibenclamide Treatment in Traumatic Brain Injury: Operation Brain Trauma Therapy, 2020, Journal of Neurotrauma

Their frequent collaborators included several researchers with whom they published multiple times, such as Kevin Wang, Patrick M. Kochanek, Darci R. Smith, Amy Y. Vittor, and Stefania Mondello.

In addition to journal articles, Hayes contributed to book literature, notably publishing with Elsevier BV. Their book titled Biomarkers for Traumatic Brain Injury was released in 2020 and gained citations within the field.
