Nicole Aponte Santiago
Adjunct Professor
Biography
Dr. Aponte Santiago studies the calcium signaling pathway, crucial for proper development and linked to human developmental diseases. During her Ph.D. at the Littleton lab at MIT, she investigated two subclasses of motoneurons with different responses to calcium activity and developed a system to study synaptic competition. However, studying calcium signaling in the whole embryo is challenging due to the complex processes involved and the unique responses of different cell types to calcium signals. To address these challenges, Dr. Aponte Santiago joined Dr. Dan Wagner’s lab at UCSF as a postdoctoral researcher. She combines classic molecular biology techniques with novel whole-embryo transcriptomic analysis to study these processes. Her research uses zebrafish as a model organism to identify critical cell types and molecular components involved in early development. This work could lead to new therapeutic strategies for developmental disorders related to calcium signaling abnormalities, offering hope for future treatments.
