David is an Associate Professor and Vice Chair in the Department of Cancer Biology at the University of Pennsylvania. He is an Associate Investigator and Director of Education in the Abramson Family Cancer Research Institute, and Chair of the Cancer Biology Program in the Cell and Molecular Biology graduate group. David started the Feldser Laboratory in 2013 with the goal of understanding the causal effects of oncogene and tumor suppressor gene mutations in cancer.

Amy is a Project Manager and principal scientist in the Feldser Laboratory. Amy graduated from the Penn Genetics and Epigenetics Graduate Program in 2025 having completed her thesis work in the Feldser Laboratory. Her pioneering discoveries have led to a new program of research that she oversees which is aimed at determining the biological effects and therapeutic potential of histone variant expression in lung cancer.

Katie is a student in the Cancer Biology Program at Penn. She graduated from the University of Rochester in 2016 and worked at the Rockefeller University for three years prior to coming to Penn. Katie’s work focuses on understanding synthetic lethal gene interactions in lung cancer. She is funded by an F31 fellowship from the NCI.

Valerie is a student in the Cancer Biology Program the University of Pennsylvania and graduate of the University of Puerto Rico - Mayagüez. She joined the Feldser Lab in March of 2024. Her work aims to determine the consequences of epigenetic deregulation in lung adenocarcinoma.

Akino obtained her Ph.D. from Bharathidasan University, Trichy, India. She moved to the Feldser lab in July 2024 where she works on signaling pathways active in lung adenocarcinoma development.

Dain is a student in the Cancer Biology Program at Penn. He joined the Feldser Lab in 2025 and is currently exploring projects related to the overlapping biologies of key tumor suppressor genes in lung adenocarcinoma.

Sydney is a student in the Cancer Biology Program at Penn. She joined the Feldser Lab in 2025 and is developing tools to interrogate mechanisms of oncogene induced cell lethality in cell culture and in the mouse.

Tony is a Masters student in the Biotechnology Program at Penn SEAS. Tony is a graduate of the University California, Davis with degrees in Music Composition and Molecular and Medical Microbiology. Upon joining the lab in the Fall of 2025, Tony became interested in understanding the biology of p53-mediated tumor suppression.
