Arpiar “Arpy” Saunders earned his B.A. in Biology and Linguistics from Swarthmore College in 2006.


He researched wild-flower genomes at the University of Montana before moving to Harvard Medical School for doctoral and postdoctoral training. At Harvard, Saunders earned his Ph.D. in Neuroscience in the lab of Bernardo Sabatini, studying the synaptic organization of the mouse brain. As a Helen Hay Whitney Fellow in Steve McCarroll’s lab, he used single-cell genomics to describe molecular diversity of brain cells.


Saunders joined the Vollum Institute as an Assistant Scientist in 2020.



Graduate Students


You perhaps? Apply through the following OHSU PhD programs: NGP, BME or PBMS



Dr. Lamya Ben Ameur

PhD Molecular and Cellular Biology
Ecole Normale Supérieure (Lyon, France)

Lamya earned her PhD in Molecular and Cellular Biology from the University Claude Bernard Lyon 1 (France). During her PhD, she  studied the interplay between chronic NF-kB activation induced by HTLV-1 oncoprotein Tax and alternative splicing. She is fascinated by the molecular mechanisms through which cells adapt to their environment, especially after pathogen infection.

Research Staff


Zach Goode

M.S. Bioinformatics,

University of Oregon

Zach attended Oregon State University where he completed a B.S. in Biochemistry & Biophysics (2017). He then transitioned from wet lab techniques to computational analyses, and obtained his M.S. in Bioinformatics & Genomics from University of Oregon (2018). Zach contributed as the bioinformatician in the lab of Joan and Ron Conaway at Stowers Institute in Kansas City, MO for three years before joining Saunders Lab at the Vollum Institute in 2021.

Emily earned her B.S. in Biochemistry and Molecular Biology in 2020 at Linfield College in McMinnville, Oregon. Her undergraduate research includes organic synthesis of small molecule inhibitors of the Arp2/3 protein complex as a cancer therapeutic. Additionally, she has experience in genome annotation of insulin signaling pathway genes across the Drosophila genus to elucidate the evolution of regulatory regions of genes to gain a better understanding of the evolution and function of biological pathways. 


Emily Tiedemann

B.S. Biochemistry & Molecular Biology 

Linfield College


Karl Young

B.S. Biology,

Reed College

Karl is from a small town called Socorro in south central New Mexico. He majored in biology at Reed College in Portland OR, studying the neural circuitry of frog vocalizations, and started in the Saunders lab following his graduation in 2020. He especially enjoys the computational and mathematical challenges involved in working with single-cell data, and in his free time likes reading (s/o Discworld by T.Pratchett), bubble tea, and goofy command line tools. His favorite food is green chile.
