People - Utz Lab


Graduate Students


Paul J. (PJ) Utz, M.D., Ph.D.
Associate Professor
Department of Immunology and Rheumatology

Dr. Utz graduated from King's College (Wilkes-Barre, PA), completed his MD at Stanford and his medicine and rheumatology training at Brigham & Women's (Boston, MA). He is an expert in multiplexed assay development, particularly protein and peptide array methods.


Rohit Gupta
Lab Manager

Rohit has been working at Stanford University since 2005. His research career began in Multiple Sclerosis under the guidance of Dr. Lawrence Steinman. Following this, he went on to work for the Stanford Prevention Research Center studying Osteoporosis. Rohit then took a year off, before returning to the lab of Dr. PJ Utz, as lab manager, and became responsible for the Stanford Immunology Registry. With the support of the Division of Immunology, Rohit expanded the services offered by the registry to the School of Medicine, and now, in conjunction with the Human Immune Monitoring Core is running the blood processing center at 1070 Arastradero. He is planning to attend graduate school to receive his MBA in the near future. In his spare time, Rohit loves spending time exploring with his wife and dog, as well as working as a freelance web designer & developer.


Justin Jarrell
Research Assistant

Justin is a California-native, born and raised in the Bay Area. He currently lives in the 'garlic capital of the world,' where he treats himself to a scoop of garlic ice cream each year at the annual Gilroy Garlic Festival. Justin completed his undergraduate studies at Santa Clara University where he majored in biology and minored in chemistry and biotechnology. Justin has been a life science research assistant in the Utz Lab since August 2009. A "jack-of-all-trades," Justin currently works on multiple projects, which include developing novel array-based methods to measure antibody response to influenza vaccination, characterizing antigen-specific T cell responses in SLE using novel tetramer reagents, and discovering prognostic biomarkers in systemic sclerosis. During the off chance Justin isn't probing arrays, he can usually be found either trail running, mountain biking, wakeboarding, or if it's hockey season, rooting for his San Jose Sharks!


Jordan Price
Graduate Student

Hailing from Madison, Wisconsin, Jordan majored in biology and cello performance at Oberlin and spent time teaching in Ecuador before joining Stanford's immunology graduate program. He currently works on array-based methods to identify new biomarkers in systemic lupus erythematosus and other autoimmune diseases, and measuring antibody response to influenza vaccination. Jordan enjoys teaching and mentoring and has served as a TA in several classes, including a class he co-developed, "Brain and the Immune System", which examines the field of neuroimmunology from many angles. He has also served as a TA and mentor for the SIMR program. When he is not processing arrays or shaping the minds of future scientists, Jordan enjoys advocating for marriage equality, playing cello in chamber music groups and with the Bay Area Rainbow Symphony (BARS), reading the memoirs of iconoclast historical figures, and his weekly hardcore nerd sci-fi watching club.


Regina Cheung
Graduate Student

Regina is a New Jersey-bred California girl: after getting her BS (in engineering) at Caltech, she spent 5 years in Boston (getting an MS in mechanical engineering at MIT in the process) before returning to CA to work on a Ph.D. in Immunology at Stanford, where she hopes to integrate her engineering degrees with technology and lupus research. Her thesis aims to elucidate dendritic cell signaling in SLE. As such, she is a member of both the Utz and Nolan labs. When she's not at school or taking care of her son Julian (born Sept 2008), she enjoys playing video games with her husband Robin, hiking, cooking, and photography (which is usually mixed up with all her other hobbies).


Jake Rosenberg
M.D./Ph.D. Student

Jake is interested in studying the relationship between infection and autoimmunity.


Gloria Yiu
M.D./Ph.D. Student

She grew up in Saratoga, California and earned her bachelors at Pomona College (CHIRP!) where she studied molecular biology and contemporary Chinese literature. She is currently interested in the roles of type I and type II interferons in systemic lupus erythematosus pathogenesis and antigen specific T cell populations in autoimmunity. Outside of lab, Gloria promotes medical and graduate student wellness and serves on a variety of Stanford Medical School committees dedicated to developing programming for student happiness and advocacy. Additionally, she is an avid practitioner of Bikram Yoga and enjoys jamming (vocals, piano, guitar), creating culinary feasts, antiquing and figure art using a variety of media. As the lab social coordinator, she also facilitates merriment through consumption of food and spirits.


Jamie Haddon, Ph.D.
Postdoctoral Fellow

Jamie grew up in the Great White North and received his bachelor's degree in biology from the University of Victoria. He went on to earn a Ph.D. in medical genetics in Dr. Kelly McNagny's lab at the University of British Columbia. Jamie has been a postdoctoral fellow in the Utz Lab since December 2010. He is interested in developing and using new technologies to learn about the mechanisms underlying autoimmune disease. Currently he is investigating the role of autoreactive T helper cells in the pathogenesis of sytemic lupus erythematosus. Away from work, Jamie likes to spend time with his family, travel, mountain bike, play soccer and read.
