Postdoctoral Fellow, NanoBiomedical Engineering, The Methodist Hospital Research Institute




Dr. Ananta joined The Methodist Hospital Research Institute in January, 2011. For his      graduate thesis, he worked on the development of carbon-based nanomaterials as contrast agents for MRI. His research experience includes functionalization and characterization of nanomaterials for biomedical applications. In TMHRI, he is working on developing multifunctional “Theragnostic agents” using nanomaterials.

Description of Research

  • Development of novel imaging contrast agents (optical, MRI, SPECT & PET) and study of their in vitro and in vivo characterization and biodistribution.
  • Imaging and targeted delivery of drugs to arteriosclerosis, breast cancer metastasis and ovarian cancer.
  • Specific sub cellular localization of magnetic nanoparticles.

Major Areas of Research

Magnetic Resonance Imaging, Multimodal Imaging, Cell and Molecular Imaging, Nuclear Imaging.
