Research Focus:

Our research involves epigenetics, proteomics and protein homeostasis. In particular, we are focused on the role of histone modifications in amyotrophic lateral sclerosis (ALS). ALS is a progressive and fatal neurodegenerative disease. Both familial and sporadic ALS produce similar symptoms; familial ALS represents 5-10% of cases. Familial ALS has been linked to a multitude of genes. How can so many genes produce the same symptomatology? We hypothesize that epigenetic mechanisms—namely histone modifications—play a pivotal role in ALS. Interestingly, a growing body of epidemiologic data suggests that neurodegenerative diseases occur less frequently in cancer survivors, and vice versa. We will study how disruptions in protein homeostasis could lead to cancer processes, and explore the overlapping aspects of neurodegenerative disease and cancer to develop strategies that could prevent both diseases.
