My research experience spans diverse fields, e.g. cell and molecular biology, biophysics, physiology, and molecular toxicology. The fundamental aspects of the pathophysiology of diseases have motivated my research. I completed my training in veterinary medicine, but subsequently discovered my interests in public health. I received my doctoral degree in environmental and occupational health.

Training in Environmental Health: My research over the past 14 years has focused on nanotoxicology, a new field of molecular toxicology that includes projects addressing the safety and toxicological assessments of nanomaterials, the emerging environmental contaminants. I have been one of the leading contributors to several pioneering discoveries in this field. As my doctoral training progressed, I became more convinced of the need for new methods and tools for nanomaterial safety assessment.

My interest to develop novel models and technologies to study the health effects of the next generation engineered materials that require screening methodologies typically unavailable, along with endpoints not previously evaluated using current guidelines, led me to the Harvard School of Public Health, where I pursued my postdoctoral training.

At UTHSCT, I have been interested in developing high-throughput screening assays for evaluating the carcinogenic and fibrogenic potential of nanomaterials. We are in the process of developing a more extensive database of corona composition of a diverse nanoparticle library to help predict the effects and biokinetics of inhaled nanoparticulates

Research Interests

Despite overwhelming scientific evidence on the health effects of environmental pollutants, there are significant gaps in our knowledge of how to monitor exposures to complex toxic mixtures and their integrated effects. Further, currently, there is only a limited understanding of the underlying biology that governs toxic mixture-induced lung diseases.

Catching the pathological events early occurring under a stealth mode after exposures to hazardous agents is the biggest untapped opportunity to have a major impact on early detection and treatment of lung diseases. Our research focuses on exosomes, 30-140 nm extracellular vesicles (EVs) actively secreted by cells, to gain insight into these knowledge gaps.

Our group is interested in examining the composition of the EVs and their predictive power to identify toxic mixtures of public health concern and to provide a snapshot of the health status of lungs.
