Description Of Graduate Research:

I am looking into the astrocytic response to sensory stimulation and the involvement of astrocytes in sensory system plasticity at the mesoscopic level. To accomplish this in the lab, we use an in vivo preparation combined with confocal and two-photon microscopy to monitor calcium levels in astrocytes via a genetically encoded calcium indicator. This method provides us with data of astrocytic responses over a landscape that can later be analyzed using graph theoretical models. This study will detail astrocyte involvement in cortical representations and plasticity.

Why Did You Choose MN?

I chose the U of MN because of all of the great research groups, strong collaborative feel, and state of the art equipment and facilities.

Student Mentor and the Best Advice They Gave.

Nathalia Torres Jimenez: She provided me with a general idea of the academic landscape within the University to better select rotations, what places to look for apartments when I moved into the Twin Cities, and any and all questions about classes and grad school life.
