RESEARCH INTEREST

My research focuses on understanding how DNA repair processes—particularly those involving mitochondrial DNA (mtDNA)—contribute to physiological function and disease. I am especially interested in the role of mitochondrial genome maintenance in aging, cancer, and neurodegeneration. Loss of mtDNA integrity compromises mitochondrial function, disrupts cellular energetics, and promotes genomic instability—hallmarks of many pathological conditions.

A central focus of my work is the base excision repair (BER) pathway and the role of key enzymes such as APE1 in sustaining mitochondrial homeostasis after genotoxic stress. I also examine how environmental factors impact mtDNA repair and mitochondrial signaling.

In addition, I am continuing the cardiovascular research program initiated by my late colleague, Dr. Sabzali Javadov, with a focus on the role of mitochondria in cardiac injury, particularly during ischemia-reperfusion (IR). Our studies investigate the interplay between regulated cell death pathways—including ferroptosis, apoptosis, necroptosis, and autophagy—and mitochondrial dysfunction, with the aim of identifying therapeutic targets for cardioprotection.

To address these questions, my laboratory utilizes Saccharomyces cerevisiae to investigate the core mechanisms of genome stability, which we then translate to mammalian systems, including human cell lines and mouse models. We utilize a range of experimental tools, including bioenergetics profiling (Seahorse XF), live-cell imaging, and,  in vitro, in vivo, and ex vivo models of human diseases, to elucidate the intersection of DNA repair and mitochondrial function in health and disease.
