Akansha Singh

akansha singh

Akansha Singh is a research fellow. She received her Ph.D. in biomedical engineering focused on tissue engineering and regenerative medicine from the National Institute of Immunology, India.

Her research interests focus on the identification of novel immunomodulatory therapies for enhanced tumor suppression. My research projects specialized in utilizing different High-Intensity Focused Ultrasound (HIFU) parameters and combining them with anti-tumor drugs and immunotherapies for improved and targeted anti-tumor outcomes.

She is also working on devising multi-functional micro/nano polymeric particles that attune tumor microenvironment for augmented immune cells activities against tumor cells in pre-clinical models.
