Ph.D. 2022

 

Thesis Title:

Mechanisms and consequences of HSF1 degradation in Huntington's disease

Current Position:

Senior Biosystems Application Manager, Nikon Instruments

Previous Position(s):

Postdoctoral Researcher
University of Minnesota

Undergraduate Institution and Major:

University of Texas, B.S. in Neuroscience, 2017

Graduate Advisor:

Rocio Gomez-Pastor, Ph.D., Department of Neuroscience

Description of Graduate Research:

My research is focused on the role of Heat Shock Factor 1 (HSF1) in the context of Huntington's disease (HD). I am particularly interested in uncovering mechanisms for neuronal dysfunction and synapse loss in HD and how HSF1 could be mediating this hallmark of the disease.

Undergraduate or Post-Bac Research

My work as an undergraduate focused on the genetic mechanisms of behavior and how they contributed to neurological disorders. The main project I worked on used C. elegans to characterize a novel regulatory apoptotic pathway. 

What Got You Interested In Research?

I was required to take a research methods course during my freshman year as an undergraduate. Most of the students in the class were only there to get the credit and leave. However, I found myself enthralled by everything research had to offer. My instructor for the course was an incredible mentor and encouraged me to delve deeper into research during my time as an undergraduate. The lab I worked in for the rest of college not only increased my passion for neuroscience but established my desire to make an impact in the scientific community.

Why Did You Choose MN?

I was initially drawn by the neurodegenerative disease research. However, the highly collaborative spirit between faculty, cohesiveness of current students, and Itasca were the key selling points! 

Student Mentor and the Best Advice They Gave:

Austin Ferro: Email/talk to people who have rotated in labs you’re interested in, as they can offer the best insights.  Also that Itasca is a time to relax and bond with your classmates.

Favorite Itasca Memory:

Without a doubt karaoke night at Lobo’s is my favorite memory. We danced, sang our hearts out, teamed up with a bachelorette party, and got everyone in the bar to join a conga line. The cherry on top, though, was Armani serenading us with Britney Spears.
