Board Certifications



Dr. Vaishnav received her Bachelors in Zoology in 1996 and Masters in Biochemistry in 1998 from the Maharaja Sayajirao University in Vadodara, India. She received further training in Molecular Biology at Loyola, completing a Masters' thesis under the guidance of Dr. Lucio Miele in 2002. She worked at the Oregon Health Sciences University prior to pursuing doctoral studies at the University of Kentucky. During her dissertation studies under the mentorship of Dr. Thomas Getchell, she combined contemporary proteomics and genomics with cellular and 'tissue-level analyses to obtain a comprehensive "systems level" understanding of olfactory degeneration. She then received an NIH National Research Service Award to pursue her postdoctoral training in therapeutic mechanisms of acute spinal cord injury in Dr. Edward Hall's lab. She joined the faculty at the University of Louisville School of Medicine in 2010.

In addition to her interest in research, Dr. Vaishnav enjoys teaching. She has mentored undergraduate and graduate students and taught various courses at the University of Kentucky, University of Louisville and the Kentucky Community and Technical College System.

Research Interests

Neurodegeneration has been associated with certain molecular and cellular processes that include elevated oxidative stress and associated DNA damage, protein oxidation, and lipid peroxidation; mitochondrial metabolic decline; increased apoptosis; and increased inflammation. Research has revealed that while neuronal loss by apoptosis seems to playa major role in neurodegenerative disorders, it is unlikely to be a predominant factor in normally aging brain. Rather, subtle molecular changes, such as oxidative stress-induced damage and mitochondrial impairments, appear to have a significant impact on neuronal functional decline in aging brain, predisposing aging brain to further insults and leading to the dysfunction and apoptosis that is characteristic of neurodegenerative disorders. Dr. Vaishnav's overall interests are in identifying basic molecular alterations associated with normal aging and neurodegenerative conditions in order to gain mechanistic insights and identify therapeutic targets.
