Xiaojuan obtained her Ph.D. in biomedical engineering from Boston University, where she developed novel peptide-based coatings for rapid modification of biomaterial surfaces for orthopedic implant applications. She then moved to MIT to pursue her postdoctoral research under the supervision of Dr. Daniel Kohane and Dr. Robert Langer. There, she was involved in the development of antibiotic-releasing hydrogels for the trans-tympanic treatment of middle ear infections.

Xiaojuan’s research background spans the areas of surface engineering and biomaterial development. Her research utilizes numerous surface analytical methods such as atomic force microscopy (AFM) and quartz crystal microbalance (QCM-D) to study the physical, biochemical, and assembly properties of thin polymer-based films and coatings, and the nature of their interactions with biological molecules and cells.

Xiaojuan is keenly passionate about educational outreach. As an NSF GK-12 Fellow, Xiaojuan taught biology at Fenway High School , and developed a series of laboratory activities and science fair modules to support the existing curriculum. She co-designed the BIOBUGS Outbreak! module, which aims to bring scenario-based learning in microbiology and infectious disease control to schools in the Greater Boston area. Xiaojuan was closely involved in the development of Concept Vignettes at MIT’s Teaching and Learning Laboratory (TLL) for use at SUTD. Concept Vignettes are short educational videos designed to help students to learn a key concept in Science or Engineering.
