Kripa Nand, Ph.D.

Research Associate

Dr. Kripa Nand is a biotechnologist with hands on experience in mammalian cell culture, animal studies (rodents and sub-human primates), bioreactors, and cancer research. He earned his PhD in Biotechnology from Jamia Hamdard, New Delhi, India, in 2017. Kripa’s work has successfully brought a recombinant anti-hCG vaccine from the lab to clinical trials, developed recombinant immunotherapeutics to treat advanced-stage cancers, established standard operating procedures for large-scale recombinant vaccine production, and transferred technology to the industry. Kripa joined Rensselaer Polytechnic Institute as a Research Associate in 2018, where he led a virus-like particle-based vaccine project in the Department of Biological Sciences until August 2024. Since 2024, Kripa has been working in the Zha lab on developing a new platform to modify cell surfaces and enhance the functionality of silk-based materials in biomedical applications.
