Collaboration With UCLA Brain Injury Research Center and Children's Hospital
Image

Our lab has begun a collaborative effort with UCLA Medical Center to develop a new breath analysis technique to monitor the state of ketosis of a patient during treatment for traumatic brain injury. It is known that a ketogenic diet can help mitigate epileptic seizures after brain injury, but children on a keto diet regiment can also become too ketotic and enter a dangerous state of keto-acidosis. The current standard for clinical ketone monitoring requires a blood sample. This collaborative project with the Ketogenic Diet Program of the Adolescent Epilepsy Center at UCLA aims to create a less-invasive device that enables more regular ketone monitoring.

Students Present at U.S. National Combustion Meeting - March
