Abbey Perl, PhD

abbey-perl-headshot-160-240.jpgDr. Perl received her Ph.D. at Case Western Reserve University in the lab of Dr. Goutham Narla. Her graduate work revealed a new function of the tumor suppressor Protein Phosphatase 2A (PP2A) in the surveillance of DNA replication and the activation of the intra-S phase checkpoint in normal cell function. During her graduate career, Dr. Perl was awarded multiple awards, including an NRSA F31 Predoctoral Fellowship, and a Teaching Certificate through the ExTEND program at Case Western.

Dr. Perl joined the Green lab for her postdoctoral work to study how phosphatase activity across the differentiated layers of the skin regulates desmosome function and proper skin barrier formation using biologically relevant model systems including primary keratinocyte and 3D organotypic cultures. Her goal is to utilize the insights gained from studying normal skin models to understand how phosphatase dysregulation may contribute to disease states, specifically focused on diseases associated with impaired desmosome function that result in skin fragility and cardio-cutaneous co-morbidities that result in arrhythmogenic cardiomyopathies.
