Year of graduation: 

I joined the Human Toxicology Program at the University of Iowa in 2007

I’ve probably always been interested in Science in one form or another, and in particular I’ve been drawn to Biology. I did my Veterinary Medicine followed up with masters in Pharmacology and Toxicology. As an aspirant of Molecular Toxicology, I have an intriguing desire inside me to comprehend the molecular basics of complex toxicological mechanisms taking place at the cellular level that leads to cancer. An extremely distinguished faculty, a milieu replete with academic activity, and a graduate program which blends high quality course work and research facilities at the cutting edge of every sub-field are the factors which have motivated me to choose The University of Iowa for PhD program in Human Toxicology. I feel that doctoral study at this University will be the most logical extension of my academic pursuits and a major step towards achieving my objectives.

Previous education:

Doctorate in Veterinary Medicine
Tamil Nadu Veterinary and Animal Sciences University, India, 2003
M.V.Sc, Pharmacology and Toxicology
Kerala Agricultural University, India, 2005
Current research description: 

I am interested in studying the role of polychlorinated biphenlys (PCBs) on DNA damage, cell cycle disturbance along with the regulation of telomerase activity in the development of lung cancer.


Thesis title: 

Telomerase and telomere dysregulation in polychlorinated biphenyl (PCB) exposed human skin keratinocytes
