Rebecca Yelton

Rebecca joined the lab in the Fall of 2019 as a research administrative assistant. Before joining the Penn team, Rebecca worked at Hahneman University Hospital as an administrative assistant for the Hematology & Oncology outpatient clinic. Rebecca graduated from Temple University with a BA in Linguistics. When Rebecca is not supplying administrative support to the lab, she enjoys crochet, researching dialects, and listening to horror podcasts. 

Patrizia Porazzi, PhD

Patrizia joined the lab in October 2021. She is a passionate cancer biology scientist, and she loves, even more, mentoring the next generation of scientists. Patrizia obtained her PhD in Medical Biotechnologies and Translational Medicine from the University of Milan (Italy). She moved to the United States for her post-doctoral training at Thomas Jefferson University (Philadelphia). During that time, she studied the role of chromatin structure and epigenetic modification in response to chemotherapy in acute myeloid and lymphoid leukemias. As a senior scientist in Ruella’s lab, Patrizia is studying how the epigenetic landscape of lymphomas may affect the efficacy of CAR T cells or cause resistance. In addition, Patrizia is working collaboratively with the personnel in the laboratory in the execution of experiments, and she works with the Principal Investigator on scientific projects development. Out of the lab, she loves running and hiking with her dog and organizing cultural and social events relevant to her Italian heritage.

Guido Ghilardi, MD

After graduating from the University of Eastern Piedmont in Novara, Italy in 2015, Guido went on to complete a residency program in Hematology at the Oncology Institute of Southern Switzerland, a world-recognized center for the treatment of lymphoid malignancies.

During his training, Guido had the opportunity to enrich his knowledge through the very useful collaboration in basic, clinical, and translational research projects that sparked an in immense curiosity and interest to further deepen his knowledge in each and every field of hematology research. In particular, Guido has developed a crescent interest in adoptive cell-therapy and the contribution that this treatment might provide in the management of lymphoproliferative disease.

To further improve his knowledge on this topic Guido has joined the Ruella Lab in order to study the biology mechanisms of relapse after chimeric antigen receptor (CAR) T-cells treatment and new strategies to improve the efficacy of this promising therapy.

Ivan Cohen, PhD

Ivan is a post-doctoral research assistant who joined the lab in January 2021. He received his PhD from Memorial Sloan Kettering Cancer Center, where he studied the links between glucose metabolism and immune suppression in solid tumors. During his PhD and post-doctoral training, Ivan has been interested in understanding various mechanisms of immune evasion to improve the efficacy of immunotherapy. In the Ruella lab, he hopes to develop novel ways of treating various hematologic malignancies. In his spare time, Ivan likes to watch and play soccer.

Alberto Carturan, MD

I’m Alberto Carturan, and I graduated from University of Ferrara, Italy in 2017. Currently I’m in a residency program in Hematology at the AOU – Ospedali Riuniti di Ancona, in Italy. Recently, the onco-hematological world has begun to fascinate me and I have developed a particular interest in everything related to immunotherapy. During my training, knowing the stories and illnesses of many people has cemented my desire to continue in this area and to learn everything possible in order to be useful in treating hematological diseases. Thanks to clinical studies and the research projects and carried out in Italy, I have developed a growing interest in adoptive cell-therapy and in its enormous potential in the therapy of lymphoproliferative diseases. This led me to join the Ruella Lab, in order to study the mechanisms of relapse after therapy with chimeric antigen receptor (CAR) T-cells and with the certainty of being able to exponentially increase my scientific knowledge in Immunotherapy. In my spare time, I like to watch TV-series, workout and spend time with my family.

Mathew Angelos, MD, PhD

Mat is a Hematology/Oncology fellow in the Physician Scientist Pathway (PSP) at the University of Pennsylvania. He received both his MD and PhD (Microbiology, Immunology, and Cancer Biology) at the University of Minnesota and completed his residency in Internal Medicine at the Hospital of the University of Pennsylvania. His doctoral research investigated the molecular mechanisms underlying human hemato-endothelial cell differentiation. He joined the Ruella Lab in July 2021. Mat is interested in expanding adoptive cellular therapies (CAR-T and CAR-NK) against hematological malignancies, specifically myeloid and T-cell leukemia. In his free time, Mat enjoys NY Islanders hockey, Duke basketball, and landscape photography

Christopher "Tor" Sauter, MD

I am a second-year Hematology/Oncology fellow at the University of Pennsylvania. My academic interests are in lymphoid neoplasms and adoptive cellular therapies. My research specific focus is understanding and augmenting the cytotoxic potential of CAR T-cells, which I pursue within the lab of Marco Ruella. I attended Emory Medical School, during which time I spent a year working in the lab of Terry Fry at the NCI. Following this, I returned to my home of Philadelphia where I completed my internal medicine training and continue now as a Hematology/Oncology fellow. In my spare time I enjoy helping my two-year-old explore the wonders of the world through hiking, camping, canoeing, stargazing, and, of course, spending lots of time on the playground. Additionally, I enjoy bicycling, cooking, and reading biographies, history, and science fiction.
