Dr. Ko is a Research Scientist in the Resuscitation Science Center (RSC) where she leads development and application of non-invasive, optical neuromonitoring technologies to detect and help mitigate neurological injury in preclinical and clinical studies of resuscitation and extracorporeal life support. She also leads implementation of preclinical data architecture and data standardization within the RSC to facilitate predictive model development with an emphasis on prediction of resuscitation success and of neurological injury.

Research focuses include:

  • Diffuse optical techniques for non-invasive measurement of tissue oxygen saturation, blood volume, blood flow, oxygen metabolism and mitochondrial health.
  • Examining the relationship of cerebral and systemic physiologic response to clinical interventions.
  • Developing brain-directed management strategies to improve neurological outcomes following cardiopulmonary resuscitation and extracorporeal life support (e.g., cardiopulmonary bypass, ECMO).
  • Preclinical large animal bioinformatics and machine learning for prediction of neurological injury.
