Antimicrobial and cell penetrating peptide design and self-assembly
Nanomaterials for drug and gene delivery
Hydrogel biomaterials and tissue engineering
Our research program lies at the interface of chemistry, materials science and biology with an emphasis on molecular self-assembly and supramolecular chemistry of soft matter nanomaterials. Current research is primarily focused on the supramolecular assemblies based on peptides, proteins and polymers. The goal is to fundamentally understand specific molecular interactions involved in natural proteins and utilize the knowledge acquired to guide the synthesis and assembly of manmade materials as protein mimics. These materials exhibited well-defined hierarchical structures and various built-in biological functions to suit a wide range of applications in drug and gene delivery, antimicrobial therapy and tissue engineering. While our research emphasis is on soft matter assembly, we also seek to integrate the study of inorganic colloidal nanoparticles into our program to broaden the utility of these hybrid materials.
He Dong jointed UT Arlington in Jan 2018 as an Associate Professor. Prior to this position, she was as an Assistant Professor in the Department of Chemistry and Biomolecular Science at Clarkson University (2012-2017). He Dong obtained a PhD degree in organic chemistry at Rice University in 2008 where she focused on the self-assembly of nanostructured peptides into 3-D scaffolds for tissue regeneration. From 2008-2009, she was a postdoctoral researcher in Prof. Elliot Chaikof lab at Emory University focusing on anti-inflammatory peptide drug development. She continued her postdoctoral research from 2009 to 2012 in Prof. Ting Xu group at the University of California, Berkeley where she developed self-assembled hybrid peptide-polymer conjugates as long-circulating nanocarriers for cancer therapy.
He Dong’s research spans from chemistry, materials science to biomedical sciences. Currently her primary research interests lie in the construction of biomaterials based on the self-assembly of peptides/proteins and block-copolymers for a wide range of biomedical applications including drug delivery, gene/siRNA delivery, vaccine delivery and antimicrobial therapy development. He Dong has been actively involved in various educational and outreach activities by mentoring local high school students and providing opportunities for summer internship to local high school teachers. She is also an active participant to disseminate research discovery and knowledge to local community people through public lectures and discussions. He Dong recently received a NSF Faculty Early Career Award and is currently a member of the American Chemical Society, American Physical Society, Materials Research Society and biomedical Science Society.
