Nanotechnology & Drug Delivery Systems

Dr. Cocucci studies basic mechanisms of membrane trafficking and is interested in how these processes deviate during cancer development when compared to normal cells. His research adopts multiple techniques, including traditional biochemistry, cell biology, and high resolution fluorescent live cell microscopy. Dr. Cocucci’s goal is to define novel targets for cancer therapy and to improve drug delivery, studying the internalization pathways and the mechanisms of endosomal escape adopted by artificial and biological nanovectors.

Dr. Guo works on both basic research and its subsequent practical applications, focusing on understanding the mechanisms and assembly of viral DNA packaging motor, and using components of the biomotor for various applications. By applying interdisciplinary approaches including chemistry, biophysics, biochemistry, nanotechnology, bioengineering, molecular biology, cell biology, computer modeling, and pharmaceutical sciences, Dr. Guo studies RNA, DNA and proteins and their interaction.

Dr. Guo’s current project areas are:

RNA nanotechnology and its application for the delivery of siRNA/miRNA/drug for the treatment of cancers, viral infection, and genetic diseases
Nanobiotechnology, including structure, function and mechanism of Phi29 DNA-packaging nanomotor
Single molecule imaging and optical instrumentation to study the interaction of RNA, DNA, and protein
Single pore technology for DNA sequencing, macromolecule detection, and disease diagnosis, using channels of variety of viral DNA packaging motors

The Hoo (Hu) research group focuses on the functional and mechanistic exploration of immune cell-derived extracellular vesicles (EVs) and EV-DNA in the context of diseases such as cancer and chronic inflammatory disorders. The ultimate goal is to inform the rationale design of non-viral gene therapies and diagnostic/prognostic tools. Specific research interests include functional and mechanistic exploration of immune cell-derived EVs and EV-DNA in disease settings such as cancer and auto-immune disorders, engineering core-shell lipid nanoparticles (LNPs) for the targeted delivery of nucleic acids, proteins, peptides, and small molecules to support therapeutic development for cancer, chronic inflammatory diseases, and autoimmune disorder and diagnostic/prognostic biomarker development based on circulating EVs and EV-DNA.
