Assistant Project Scientists
Kelsey Jarrett, PhD

she/her/hers
I joined the lab in December 2018, after completing a Ph.D. in Integrative Molecular and Biomedical Sciences at Baylor College of Medicine in Houston, TX. My projects use liver-directed genome editing to broaden our understanding of genes involved in bile acid synthesis and lipid metabolism. I am currently using these studies to pursue my interests in male-female differences in cholesterol and cardiovascular disease. When I'm not working on something science-related, I can be found reading, baking far too many treats, or going for walks or runs to explore the city.
Madelaine (Maddy) Brearley-Sholto, PhD

she/her/hers
I joined the Tarling-Vallim lab in November 2019, after carrying out my BSc and PhD at the University of Nottingham. My current research involves investigating novel regulatory targets of bile acid and lipid metabolism by utilizing omics technology and bioinformatics analysis. In my free time I really enjoy going on hikes, as well as finding new foody and craft beer places to try.
Postdoctoral Scholars
Elinor Lee, MD, PhD

she/her/hers
Before joining the lab in 2016, I completed my BA at Amherst College and MD at University of Cincinnati, College of Medicine. I completed my residency training at Baylor College of Medicine in 2015, my fellowship training in Pulmonary and Critical Care Medicine at UCLA in 2018, and my PhD in Molecular, Cellular, and Integrative Physiology as part of the STAR program at UCLA in December 2020. I am currently an Assistant Clinical Professor and postdoc in the lab. My research focuses on understanding the role of lipid metabolism in lung homeostasis and disease with the goal of translating bench work to the clinical setting.
Heidi Schmidt, PhD

she/her/hers
Before joining the Tarling-Vallim lab in February 2022, I completed my BSE. in Biomedical Engineering at Case Western Reserve University and my PhD in Molecular Pharmacology at the University of Pittsburgh in the lab of Dr. Adam Straub. In the Tarling-Vallim lab I am combining my previous research experiences in obesity and vascular biology to study the post-transcriptional regulation of metabolic genes in the liver by the ZFP36 family of RNA binding proteins. In my free time, I love exploring LA, going for hikes, and trying new foods!
PhD Graduate Students
Alvin Chan, MD

he/him/his
As a pediatric gastroenterologist, I am interested in the regulatory role of bile acids in health and disease. My work leverages in vivo and molecular approaches to understand how changes in bile acid homeostasis shape intestinal lipid absorption and systemic metabolism. Prior to joining the lab in 2020, I earned my B.S. from the University of California, Berkeley; M.P.H. from the Harvard T.H. Chan School of Public Health; and M.D. from the University of California, Irvine, where I was inducted into the Gold Humanism Honor Society. I then completed my pediatric residency and gastroenterology fellowship at UCLA. With support from the UCLA Specialty Training and Advanced Research (STAR) Program, I pursued a Ph.D. in the Department of Molecular, Cellular and Integrative Physiology during fellowship, investigating the selectivity of bile acids in driving fatty acid absorption. Outside of work, I enjoy running and spending time with my wife (also a pediatrician and runner) and our two kids.
Emily Smith (Peluso), PhD

she/her/hers
Emily graduated from the University of North Carolina Chapel Hill in 2017 with a degree in Biology. As an undergraduate researcher, she studied small molecule signaling in the bacterial pathogen, Clostridium difficile. She then went on to complete a two year fellowship at the National Institutes of Health in Bethesda, MD. There she studied the kinetics of spore formation in the model organism, Bacillus subtilis (Peluso et al., PNAS. 2019). She began graduate school at the University of California Los Angeles in 2020. In the Tarling-Vallim lab, Emily’s thesis work focuses on understanding how cells within the liver adapt and respond during healthy and diseased states. Specifically, Emily’s work has provided novel insights into how peroxisomes, an important organelle in lipid metabolism, maintain biogenesis and control protein import. Following graduation, Emily aims to work in Biotechnology to continue moving science forward in a meaningful way. In her free time, Emily enjoys spending time with her daughter, husband, and dog. Some of her favorite things to do are running through the mountains, reading a good book by the pool, and sharing a meal with family and friends.
Gabriella Rubert

she/her/hers
I am a Southern California native and graduated from Boston College in 2020 with a BS in Biochemistry before joining the Molecular Biology Interdepartmental Doctoral Program here at UCLA. I officially joined the Tarling-Vallim lab for my thesis work in July 2021 and am interested in the epigenetic factors regulating lipid metabolism in the liver. As a Latina woman, I am very passionate about improving the accessibility and inclusivity of higher academia for underrepresented groups to address the disparities we see in STEM fields. Outside the lab, I enjoy spending time with family and friends, exploring Los Angeles, lifting weights, and snuggling up with a good book beside my pets.
Isaiah Little

he/him/his
After receiving my B.S. in Microbiology, Immunology, and Molecular Genetics and working as a staff research associate for two years at UCLA (Go Bruins!), I joined the lab in the summer of 2024 as a PhD student in the Molecular Biology Interdepartmental Program (MBIDP) under Dr. Elizabeth Tarling. Broadly, I am interested in how lipid dysregulation modulates pulmonary immunology and fibrosis with a special interest in alveolar macrophages. Though a long-time serial hobbyist, I love to run, climb, cook, and homebrew mead and hard cider in my free time.
Rochelle Lai, RD

she/her/hers
I am a registered dietitian (RD) by training, but am fascinated by nutrition & metabolism basic science. I received my undergraduate degree at UC Berkeley in 2017 and completed my master’s degree & dietetic internship at USC in 2019. Then, I worked at Stanford Medicine Lucile Packard Children’s Hospital as a clinical RD, specializing in liver & intestine transplant. In 2022, I started the Molecular, Cellular and Integrative Physiology PhD program at UCLA and joined the ETV lab in April 2023. In my spare time, I like to try new recipes and explore new places to eat.

Angela Cheng

she/her/hers
I was born and raised in Suriname, a country in South America. I came to the US to further my education and graduated from UC Berkeley in 2014. I joined the ETV lab that same year, and I have been at UCLA since then.
Michelle Steel

she/her/hers
I joined the Tarling-Vallim Lab in March 2020 after closing out the Arispe Lab at UCLA. I’m a registered veterinary technician by trade and have fewer letters behind my name than the rest of the lab, but what I lack in letters I makeup with experience. I started my career at UCLA in 2001 in DLAM as an animal health technician and know lots of tricks, but I am best known for my mouse skills and navigating through all of the compliance activities. When I’m not wrangling mice or tackling a protocol, you can find me spending time with my family, tending my garden, or playing with my horses.
