## Abstract

Project Summary/Abstract
 I am a physician/scientist focusing on the development of optical neuroimaging techniques to improve
bedside detection of neurologic injury in critically-ill children. The goal of my mentored career development award
is to acquire training in mouse models of hypoxia as well as in advanced statistical methods for the analysis of
resting-state brain activity. This training will launch an independent research career with the aim to bring imaging
biomarkers from bench to bedside.
 Many pediatric diseases that were once universally fatal (e.g., complex congenital heart disease and extreme
prematurity) now have relatively good survival rates. However, neurodevelopmental outcomes have improved
only marginally. With timely intervention, it is possible to minimize hypoxic injury, but current bedside tools are
insensitive and inadequate for this purpose. Furthermore, the heterogeneity of clinical populations limits clinical
studies. Each patient has a unique injury and treatment, and neuroimaging is performed at varying times after
injury; thus, it can be difficult to rigorously analyze such data to determine the best, most generalizable
biomarkers.
 The present work aims to solve these problems by using mouse models of hypoxemic neurologic injury,
robust statistical methods, optical functional neuroimaging techniques, and resting-state hemodynamic
assessment (e.g., functional connectivity). The optical methods are similar to functional magnetic resonance
imaging but have much lower cost, higher portability, and higher through-put. My proposal will test the hypothesis
that resting-state hemodynamic metrics can serve as neuroimaging biomarkers of injury after acute and chronic
hypoxia. Aim 1 will develop statistical methods adapted to optical neuroimaging to permit more robust noise
filtering, brain segmentation, atlasing, and image analysis. Aim 2 will use resting-state hemodynamics in the
hyperacute phase of ischemic stroke to identify the penumbra. Aim 3 will study the longitudinal development of
functional connectivity networks across mouse development and the disruptive effects of chronic hypoxemia.
 This research will be conducted under the mentorship of Arjun Yodh, PhD, with co-mentorship by Daniel
Licht, MD; both faculty are recognized leaders in the development of optical neuromonitoring techniques. In
addition, I have assembled an interdisciplinary group of collaborators with expertise in mouse models of
hypoxemia, neuroimaging statistics, and advanced network analysis methods. I will benefit from this excellent
mentorship and research environment, and my unique optical neuroimaging methods offer a path to
independence. I am a board-certified pediatric cardiologist, and my long-term career goals are to combine
neuroimaging with a tenure-track position at a pediatric research hospital. The exceptional research environment
at CHOP/Penn will enable future translational studies in the intensive care unit, as well as further a...
