Lab Team

Nicole DeMarco

Laboratory Manager and Head, Basic Science Section

Nicole is interested in all avenues of research, but has particular experience in genetics, developmental biology, and mouse disease models. She joined the Hill Lab after working as a research technician for 4.5 years and completing a Master's Degree in Bioinnovation at Temple University. In her free time, Nicole likes to play with her dogs, read, and watch horror movies.

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.

Stanislaw Gabryszewski, MD, PhD

Fellow Physician

Stan is a clinical fellow in Allergy and Immunology. His research is focused on better understanding the epidemiologic and immunologic relationships between systemic and gastrointestinal food allergies. His current projects include modeling of pediatric allergy patterns using electronic health record data and elucidating mechanisms underlying oral immunotherapy-induced eosinophilic esophagitis. Stan's hobbies outside of the lab include running, cooking, and playing the violin.

Liv 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).

Samuel McCright

Graduate Student

Sam (he/him/his) is an MD-PhD student in the Penn Immunology Graduate Group. Originally from Ohio, he attended Oberlin College before moving to Philly. In lab, Sam is interested in how metabolic disease causes dysfunction of the innate immune system, particularly in the context of respiratory diseases such as asthma. Outside of lab, he enjoys wandering around the city, cooking, and caring for an ever-expanding collection of houseplants.

Eric Rodriguez-Lopez

Graduate Student

Eric (he/him/his), born and raised in Ponce, Puerto Rico, is a PhD candidate in the Immunology Graduate Group at Penn. He is interested in understanding the mechanisms of allergic inflammation, specifically how unconventional immune responses play a role in these. When Eric is not in lab, he is most likely singing! He is a part of Penn Collegium Musicum and the Mendelssohn Chorus of Philadelphia. In addition, he is training to become an opera singer. Eric also enjoys finding great food in the Philadelphia area.

Rachel Clement

Graduate Student

Rachel (she/her/hers), born and raised in the Berkshires, is a PhD student in the Immunology Graduate Group at Penn. She is interested in understanding the functions of regulatory lymphocytes in allergic inflammation. When Rachel is not in lab, she spends time with friends, enjoying the many bars/restaurants Philly has to offer. She also likes to go for hikes and spend time in nature.

Julia Chini

Graduate Student

Julia (she/her/hers) 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.

Cleandre Guerrier

Research Technician

Cleo is a research scientist in the lab. She has expertise in human flow cytometry and metabolic investigations of human innate immune cells.

Briana Williams

Research Technician

Briana is very optimistic and outgoing, but a bit on the shy and quiet side. She was born in San Juan, Puerto Rico but raised in Houston, Texas. She moved to Philadelphia in 2015 at the age of 24 to start her career path. She has several hobbies: She loves dancing, singing, modeling, skateboarding, guitar, etc. She is a supermom of a 5-year-old girl who is her world. She loves being a mom. Horror movies are her favorite; She is super obsessed with The Nightmare on Elm Street Saga. In most of her spare time she likes to play make believe with her baby girl and her dad. She is bi-lingual but prefers English outside her home. If you wanted to call her Scientist Barbie that would be just fine. Yes, she am obsessed with Barbie as well. Science is her passion and helping people is what she loves to do.

Jesse Dudley, MS

Information Analyst, DBHi

Jesse is the lab's bioinformatician. She performs clinical investigations of EMR-based disease cohorts and studies of transcriptional and other 'omic data sets.
