Dr. Nikhil Tyagi is working at University of South Alabama Mitchell Cancer Institute (USAMCI). He received his Ph.D. degree in 2011 from Delhi University, India. During his Ph.D., he worked in the area of nanotechnology with specific focus on targeted drug delivery to cancer cells. Currently, he is working on the various aspects of cancer biology that includes understanding the molecular mechanism of progression and metastasis of pancreatic, prostate, breast and skin cancer, development of novel delivery systems for target specific drug delivery and application of silver nanoparticles for prevention of skin cancer.
