Spinocerebellar ataxia type 1 (SCA1) is a dominant, fully penetrant, neurodegenerative disease characterized by progressive motor dysfunction and premature death. SCA1 pathology in the brainstem, underlying lethal aspects of the condition, is poorly understood. My research uses genetic, molecular, and computational approaches to elucidate molecular mechanisms of SCA1 in the brainstem.

Undergraduate or Post-Bac Research:
Neuroscience, University of Minnesota – Harry Orr
I did my master’s thesis in Harry Orr’s lab. I determined the efficacy of using antisense oligonucleotides for prevention of the synthesis and aggregation of mutant ataxin1 protein in mouse models of Spinocerebellar Ataxia Type 1. I used a variety of molecular approaches as well as imaging.
Molecular Genetic Pathology, University of Minnesota – Matthew Bower
While I was a genetic counseling student, I worked with Matt Bower to assess the yield of exome sequencing in determining a genetic cause of disorders of sexual development for patients without a known molecular diagnosis. I used computational tools to analyze raw Next Generation sequencing data for diagnostic purposes.
Developmental Neurobiology, University of California, Los Angeles – Bennett Novitch
I spent a summer using molecular and genetic approaches as well as imaging techniques to explore the function of FOXP1, FOXP2, and FOXP4 proteins in the regulation of neural development through characterization of their expression in the developing mouse brain.
Molecular and Cellular Biology, University of Puget Sound – Mark Martin
As an undergraduate I used molecular and behavioral approaches to determine the relationship between cloacal microbial communities and phenotype, specifically reproductive success, of the striped plateau lizard.
What Got You Interested In Research?
When I was in 5th grade I had an incredibly supportive and influential science teacher. He encouraged me to embrace my scientific curiosity and went above and beyond to cultivate my research skills. I ended up dissecting a cow brain in his class and running a series of explorative experiments on the tissue from my parents’ kitchen while learning to keep my first laboratory notebook.
Why Did You Choose MN?
I love the breadth of research in the Graduate Program of Neuroscience, the collaborative nature of the research community, and the enthusiasm the faculty have for the work that they do. I also absolutely love summers in northern Minnesota, and I felt that any program that begins by sending its students to live in cabins in the north woods while learning neuroscience techniques and promoting outdoor exploration was a perfect fit for me. Additionally, I found the city of Minneapolis to be an ideal scholastic, social, and cultural fit.
Student Mentor and The Best Advice They Gave:
Amy Nippert – The best advice she has given me so far has been to remain open to rotations and learning opportunities outside my comfort zone
Favorite Itasca Memory:
My favorite Itasca memory was participating in a class yoga session one morning while looking out over Lake Itasca.
