Current Lab Members

Josh Bonkowsky

Principal Investigator

Bio: Josh is a pediatric neurologist specializing in clinical care and research.  He is a professor of Pediatrics at the University of Utah School of Medicine, and Primary Children’s Hospital.

After graduating from Harvard College, he spent one year on a Fulbright Fellowship in Vienna, Austria.  He received his MD and PhD degrees from the University of California, San Diego, and completed residency training at the University of Utah (pediatrics), Children’s Hospital of Boston and University of Utah (pediatric neurology). 

In his “spare” time he enjoys camping with his daughter, building a quasi-functional radio telescope with his sons, and trail running.

Tammy Stevenson

Lab Manager

Research: In addition to being the lab “mom”, Tammy is currently testing potential gene therapies for Zellweger Spectrum Disorder and also functions as the lab’s “closer”, working to do final experiments needed to get publications out the door.

Bio: Tammy grew up in Wisconsin and Pennsylvania, graduated summa cum laude from UC San Diego with a major in molecular biology, and also did a piano performance major at California State University Stanislaus. When she’s not pipetting things, she enjoys racewalking, trail running, playing chamber music, and reading. 

Quentin Raas

Post Doc

Research: Quentin’s research focuses on the group of leukodystrophies with defects in proteins of the peroxisome such as X-linked Adrenoleukodystrophy. Using zebrafish as a model organism, the goal is to better understand these pathologies and their phenotypic variability and find treatments.

Bio: Quentin did his PhD working with cellular models of peroxisomal leukodystrophies in the lab of S. Savary, at the University of Burgundy in France. When he is not in the lab, he enjoys playing music, traveling and visiting Utah or doing some outdoor activities with his family.

Sam Zoucha

Neonatology Fellow

Pi-Kai Chang

Post-Doc

Research: Pi-Kai studies the cause of eIF2B5 R191H mutations in vanishing white matter disease, and is also testing a gene therapy in eIF2B5 R191H mutant mice.

Bio:  Pi-Kai is a super-tall cat-loving Taiwanese post-doc with a Ph.D. in Pharmacology and Physiology, specializing in rodent behaviors. He also has research experience in everything from deep brain stimulation to parasitology. His interests include cooking, music, and working out.

Monika Baker

MD/PhD Student

Research: Monika studies how to use machine learning to better understand treatment resistance in pediatric epilepsy and to inform better treatment practices.

Bio: Monika is a Utah native from Provo. She went to Utah Valley University and obtained a bachelor’s degree in biology, after which she taught microbiology lab. Her scientific interests are blood, microbiology, genetics, oncology, probability, and machine learning. She has a borderline pathological love of cats, but also enjoys cycling with her husband, reading Science fiction, and playing metroidvania games.

Sarv Raafati

Undergrad

Research: Sarv contributes to the lab’s continued study of Vanishing White Matter disease. She is currently establishing a zebrafish line to study the disease in relation to astrocytes. When not working on her own project she is picking up tasks around the lab to help other people’s work.

Bio:  Sarv is Utah born and raised. She is currently completing a degree in Biomedical Engineering and Persian Language minor through the University of Utah. Her first love of science started with astronomy. Outside of the lab, she enjoys breaking her yearly reading goal, skiing, and rollerblading, if not planning her next big trip.

Dana Schiwal

Undergrad

Research: Dana’s research focuses include helping to establish a suitable zebrafish model for X-linked adrenoleukodystrophy, as well as more recently working with vanishing white matter model mouse brains, furthering the lab’s projects on VWM. In her extra time, she picks up extra tasks and mini-projects around the lab.

Bio: Dana is from Layton, Utah, and is currently pursuing a degree in biology, along with a minor in ceramics at the University of Utah. Some of her hobbies are pottery, reading, and keeping up to date with NASA’s latest discoveries. She also enjoys hiking in southern Utah and exploring the National Parks.  

Julia Wentz

Lab Technician

Research: Julia is a lab technician who received her LAT (Laboratory Animal Technician) certification from the American Association for Laboratory Animal Science.  Her experience in research began at the University of Utah, working for the Office of Comparative Medicine 13 years ago.  

Bio: Julia loves all sorts of ethnic foods and enjoys watching a movie or two on the weekend, but her favorite love of all time is watching her children grow into kind and caring human beings — they are the future.
