Postdoctoral researcher in neurodegenerative disease and cancer

Postdoctoral researcher in neurodegenerative disease and cancer

Location:
University of Pennsylvania - Perelman School of Medicine
Open Date:
Mar 14, 2026
Description:
The laboratory of Professor Xiaolu Yang at the Perelman School of Medicine, University of Pennsylvania, is seeking a highly motivated postdoctoral researcher to join our dynamic and interdisciplinary team. Our work investigates the fundamental mechanisms that drive neurodegenerative disease and cancer, with current projects centered around two major research areas:

 

1. Protein quality control, aging, and neurodegenerative diseases

Our laboratory has discovered two previously unrecognized protein quality control (PQC) systems involving tripartite motif (TRIM) proteins and poly-Asp/Glu (polyD/E) proteins. These pathways function independently of ATP and exhibit distinct evolutionary conservation—TRIM in animals and polyD/E across eukaryotes—setting them apart from established PQC mechanisms. Ongoing work aims to define their molecular mechanisms, elucidate their contributions to aging and neurodegenerative diseases (Alzheimer’s, Parkinson’s, ALS), and explore their potential for therapeutic intervention.

 

2. Tumor suppression, metabolism, and autophagy

We examine the regulatory mechanisms and functional roles of the tumor suppressor p53, with emphasis on its control of metabolic pathways essential for biosynthesis and redox balance. Our studies explore how p53 integrates metabolic cues by acting as both a sensor and regulator of cellular metabolism. In parallel, we are identifying metabolic changes that promote tumor initiation and progression. This work has recently expanded to include investigations into how metabolism and autophagy influence the biology of embryonic and cancer stem cells.
