Caleb Doll A native Kansan, Caleb spent fifteen years in Nashville cultivating a love for developmental neurobiology and diverse styles of music. At CU Anschutz, his group uses a zebrafish model of Fragile X syndrome to explore locomotive circuit formation. Outside of lab, his family enjoys (short) hikes and cycling through Denver. Once avid concertgoers, they now attend one show a year and insist on being home before midnight.
