CAP profile

Director - Advanced Drug Delivery and Regerative Biomaterials Laboratory (ADDReB) of Cardiovascular Institute (CVI)
Stanford University School of Medicine

Assistant Professor, Pulmonary, Allergy and Critical Care Medicine, Stanford University School of Medicine

Adjunct Professor
Department of Bioengineering and Therapeutic Sciences
University of California San Francusco (UCSF) School of Pharmacy

Dr. Rajadas is currently working on the molecular mechanism of neurodegenerative disorders caused by aggregated tau and abeta proteins-proteins that are synergically involved in Alzheimer’s disease development. He uses various biophysical approaches such as AFM, fluorescence, and NMR to understand the structural details of neurotoxic oligomeric forms of these two proteins.

Dr. Rajadas is also directing the Advanced Drug Delivery and Regenerative Biomaterials Laboratory at Stanford University. This center has been involved in transforming biophysical ideas into biomaterial and drug delivery technologies. These technologies include microencapsulation of drugs, vascular grafts, bio-implants, development of small molecule and protein-based drugs, regeneration of nerve and cardiovascular tissues, and wound healing applications.

Before moving to Stanford, he served as the founding chair of the Bio-organic and Neurochemistry Division at one of India’s national laboratories, Central Leather Research Institute Chennai, India, where he was responsible for both the organization and management of the division.
