Ingrid Murillo is a second-year PhD student in the Neuroscience and Behavior program at Northern Illinois University (NIU), where she also earned her BS in Psychology. Her research explores how the endocannabinoid system modulates circadian and ultradian rhythms, with implications for understanding circadian disruption in Alzheimer's disease (AD). Using prairie voles as a model well-suited for studying sleep fragmentation, one of AD's earliest symptoms. She applies pharmacological compounds to ex vivo suprachiasmatic nucleus (SCN) slices via 3D-printed brain-on-chip microfluidic devices. Calcium imaging of the live tissue then reveals how these compounds affect SCN activity, advancing the search for therapeutic targets for AD-related circadian dysfunction.
