Jonathan Elliott - Co-chair

Elliott, Jonathan

Department of Neurology
VA Portland Health Care System

My research background is in applied human physiology predominantly in the areas of exercise, environmental, and sleep. I completed my PhD at the University of Oregon and a two-year postdoctoral fellowship at the Mayo Clinic before moving to OHSU. I've been at OHSU since July 2016. I joined the OPDA because postdocs are a crucial component of the research-academic enterprise, and I wanted to be in a position to advocate for and support aspiring postdocs here at OHSU. You can normally find me in my lab throughout the workday, but I'm definitely at my most awake in the afternoon! 

Thierno Madjou Bah - Co-chair

Madjou Bah

Anesthesiology & Perioperative Medicine
Mackenzie Hall

I am originally from Guinea (Conakry, West Africa) and received my Ph.D. degree in 2011 from the University of Montreal in Biomedical Sciences. My research interest  at OHSU is investigating how sleep disruption after traumatic brain injury may impair glymphatic function and promote neurodegeneration. I have been at OHSU since April 2016. In my spare time, I like to shop and spend time with my family. My favorite book is Le monde de Sophie.


Cristina Espinosa - Communications Co-Officer

Espinosa, Cris

Cell, Developmental and Cancer Biology
Richard Jones Hall

I arrived to OHSU almost two years ago. I come from Spain where I did my Ph.D. in antioxidant responses in cardiovascular diseases. At OHSU, I am playing with microRNAs in tumor angiogenesis (aka tumor microenvironment). My day begins after the third coffee, so I am an evening person. I joined OPDA because I love to be involved and I wanted to do more for international postdocs like me. I love to do qPCR. When I plate it, it is just relaxing and it is like having a perfect music concert in my head. My favorite place around here is Powell´s. Books and coffee, what else do you need? I love traveling - that is how I discover the amazing Northwest.

Cristina also serves as the International Employee Resource Group Liaison for the OPDA.
