Daniela C. Zarnescu

Professor, Principal Investigator

Daniela studied Physics at University of Bucharest then received a PhD in Biochemistry and Molecular Biology at Penn State (2000) where she researched the role of spectrins in epithelial morphogenesis. Following postdoctoral training in molecular genetics at Emory University, in 2006, she joined the Molecular and Cellular Biology Department at University of Arizona where she continues to use Drosophila to study RNA based mechanisms in aging and neurodegenerative diseases. While Daniela does not have much free time she enjoys art, the theatre and watching murder mysteries.

Undergraduate Researcher

I am currently studying Neuroscience with an emphasis in cognition at the University of Arizona. My project on the RNA binding team is to study the interactions between TDP wild type and mutant flies with specific translation initiation factors through a larval turning assay. I hope to continue collecting data for this project to determine how ALS affects motor function through its interaction with protein synthesis.

Nicolai Peña

Undergraduate Researcher

Hi my name is Nic and I am studying neuroscience and biochemistry. A common molecular phenotype found in ALS models and patient samples is impaired RNA metabolism. I am specifically looking at how protein synthesis may be dysregulated in ALS motor neurons. By learning which proteins and signal pathways disrupt translation in ALS, we can begin to discover common disease mechanisms and potential therapeutic targets.
