Dose, scan, repeat: Tracking the neurological effects of oral contraceptives

We know little about how the brain responds to oral contraceptives, despite their widespread use. I am committed to changing that: I scanned my brain 75 times over the course of a year and plan to make my data openly available.

Cracking the code of the extracellular matrix

Despite evidence for a role in plasticity and other crucial functions, many neuroscientists still view these proteins as “brain goop.” The field needs technical advances and a shift in scientific thinking to move beyond this outdated perspective.
