Mason Handford- University of California- Santa Cruz, B.S. Chemistry
M. Riscoe Lab

After transferring from a community college in the California Sierra Nevada region, I earned a Bachelor of Science in Chemistry from the University of California, Santa Cruz in 2018. During my time at UCSC, I conducted research in Dr. Scott Lokey's lab, delving into the intricate interplay between lipophilicity and hydrophilicity in hexameric macrocyclic peptides, with a specific focus on their solubility and passive permeability. Following my undergraduate studies, I embarked on practical experiences, including an internship at Genentech in South San Francisco, followed by a research assistant role in Prof. Carsten Schultz's lab at Oregon Health & Science University. In 2019, I was admitted into the Program for Molecular and Cellular Bioscience graduate program. Joining Dr. Michael Riscoe's research group, my focus has been on the discovery and development of novel 4-aminoquinolines for combating multidrug-resistant malaria. During my time at OHSU, I have had the wonderful opportunity to teach chemistry at the local liberal arts college – Lewis and Clark College, for the last three years. While not in the lab, I enjoy partaking in summer bike rides, baking, cooking, playing board games, and spending time with my enchanting wife, Alexandra, and beautiful son, Theodore.

A. Janowsky Lab

My name is Julia Huey, but mostly folks call me Juli. I spent my formative years in Georgia, which can be blamed for my excessive use of the word "y'all" and firm belief that fried okra is the best vegetable. At Georgia Tech, I worked in the M.G. Finn lab in support of projects to characterize and modify virus-like particles for in vivo applications. After college, I worked as an industrial process engineer in various chemical plants and manufacturing facilities. I found my heart was still in the lab, so I decided to pursue a graduate education. At OHSU, I discovered my interest in central nervous system pharmacology and joined the lab of Aaron Janowsky. Here, I am studying the G-protein coupled receptor trace amine-associated receptor 1 (TAAR1). I am fascinated by the molecular mechanisms underpinning psychiatric disorders including addiction, and hope to better understand how chronic methamphetamine use affects TAAR1 signaling and trafficking. When I'm not in the lab, I can be found hiking the glorious Northwest with my husband Ike and our dog Cashew, or cozied up on the couch with a good podcast, our cats Blini and George, and a knitting project.

Kaya Keutler

Kaya Keutler- Albert-Ludwigs-Universität Freiburg, MS in Biochemistry and Biophysics
C. Schultz Lab

Χαίρετε (chaírete, greek for hello),

My name is Kaya Keutler and I was born in the north-west of Germany. However, my parents have left the country for many years to live abroad and therefore I grew up on a small island in Greece, where I spent a great childhood and still feel deeply connected to the sea and the sunshine. However, as a curious nature and after my diagnosis as a diabetic, I early decided to become a scientist - in later stages this idea shaped up and I decided to study biochemistry. My studies took me back to Germany, where I finished my bachelors in the small city of Tübingen, working on the purification and functional characterization of an anti-apoptotic protein in the Garcia-Saéz Lab. However, I realized that even though I enjoyed any research field, I had the desire to focus on diabetic research. That brought me to Freiburg, where I started my master studies in biochemistry and biophysics. Through the university of Freiburg I had the chance to perform an internship followed by my master thesis in the lab of Carsten Schultz in Heidelberg. There I worked on Insulin secretion and the signaling factors regulating that process. After a rather short journey I finally arrived in the research field I was aiming for. During my PhD here at the OHSU Schultz lab, I will continue working on insulin secretion trying to unravel the influence of autocrine signaling and the importance of a particular class of signaling factors called "trace amines".

Alix Thomas- Paris 7 Diderot University, MS in Biochemistry
C. Schultz Lab

I received my BA in chemistry from Paris 5 Descartes University in 2015 and then started a master in Biochemistry with a focus on the structural biology of proteins. During this master I worked on developing a protein-protein interaction assay based on UAAs incorporation and small chemical probes in the lab of Terrence Strick at the Jacques Monod Institute. I then did my master thesis in the lab of Mario Pende in the Necker Institute where I was mentored by Ganna Panasyuk. There I worked on biliary atresia, focusing on the molecular mechanisms driving autophagy. I then joined the lab of Carsten Schultz in Heidelberg for a small internship followed by a PhD here at the OHSU Schultz Lab. I am currently working on developing a FRET biosensor-based imaging platform to study the effect of combinatorial drugs on the signaling network in human cell.

S. Shyng Lab 

I am currently a PhD candidate in the department of Chemical Physiology & Biochemistry at Show-Ling Shyng lab. Originally from Egypt, I earned my medical degree from Tanta University's School of Medicine, followed by a master's degree in medical biochemistry from the same institution. My journey in science led me to the United States in 2019, where I embarked on an enriching career path within the Show-Ling Shyng lab, delving into the intricate cell signaling pathways associated with insulin secretion. Transitioning into the PBMS PhD program in 2020, I've honed my focus on exploring novel therapeutic avenues for patients with congenital hyperinsulinism.  

Beyond the lab, I find joy in various hobbies such as reading books, listening to songs, and the art of cooking. I cherish moments spent socializing, making new connections, and, most importantly, relishing quality time with my two beloved children.
