Julie Dilollo

Research Scientist and Head, Translational Science Section

As the Head of Translational Science, Julie spends her time coordinating, designing, and performing human immunological studies. Julie's primary focus in the lab is developing diagnostic assays for disease management of EoE, while making basic science discoveries along the way. She loves to collect new skillsets, and has experience with mammalian cell culture, flow cytometry, sequencing of all kinds, and lentiviral transduction. When out of the lab, Julie spends her time playing video games, visiting friends, and going to the beach as much as possible.

Olivia Harding, PhD

Postdoctoral Fellow

Liv is a postdoctoral fellow with a PhD in Cell and Molecular Biology from Penn where she studied with Dr. Erika Holzbaur. She is originally from southwest Virginia and attended the College of William & Mary before completing a post-baccalaureate fellowship with Dr. Roberto Weigert at the NIH. Liv is interested in how homeostatic mechanisms of lung immune cells are impaired in obesity, and how these effects may predispose further human pathology. Outside of work, she enjoys training for marathons and other long-distance races, reading fiction, and cooking (especially pasta).

Julia Chini

IGG MD/PhD Student

Julia is an Immunology Graduate Group MD/PhD student. She is originally from Minnesota and attended the University of Wisconsin-Madison before coming to Philly. She is studying how metabolic organs communicate with each other during obesity, and how this process can influence obesity-associated inflammation. In her free time, she enjoys exploring Philadelphia, going on hikes with her dog, and traveling.

Natasha Puzon

IGG PhD Student

Natasha was born and raised in Washington State. She is a PhD student in the Immunology Graduate Group at Penn. Natasha is interested in understanding the effects of specific dietary components on diseases of type 2 inflammation. Outside of lab, she enjoys distance running, hiking, and relaxing with her cat.

Emily Hughes

VMD Student

Emily, originally from Scranton, PA, moved to Philadelphia to attend Drexel University for her undergraduate studies and stayed to pursue her VMD at PennVet. Emily is interested in the regulation of adipose tissue function on metabolic health. In her free time, she enjoys lifting, rock climbing, and running. She also loves reading and cooking at home with her twin kittens, Marcello and Nala.

Alondra Betancourt

Undergraduate Student

Alondra is originally from Orlando, Florida, though her family is from Puerto Rico. She is currently a Penn undergraduate student in the College of Arts & Sciences majoring in Biology and minoring in Environmental Management. Alondra is a FERBS scholar and is studying the effects of diet on lung inflammation. Outside of the lab, she enjoys traveling to new places, spending time outdoors, and trying foods from all cultures.
