Clinical Interests/Research Interests

To date, Dr. Moalli’s research has mainly focused on 1) the development of novel biomaterials for use in pelvic reconstructive surgeries; 2) defining and reducing maternal birth injury; and 3) vaginal biofabrication.  A current project in the lab titled, “Defining the host response to local stress variations induced by polypropylene prolapse mesh:  The critical next step toward obviating biomaterial complications” seeks to define the delicate interplay between a biomaterial derived from polypropylene, the extracellular matrix, and vaginal fibroblasts.  Based on the data obtained, the Moalli group will design a “smart” material with properties that promote a constructive healing response.   A second project  titled, “Development of novel elastomeric auxetic devices for use in reconstructive pelvic surgeries” aims to develop a biomaterial for use in surgery that is soft and elastic with material properties and behavior similar to that of the vagina but with sufficient mechanical integrity to respond to transient increases in intra-abdominal pressure.  Her group has explored the use of bioscaffolds and living tissues generated in culture from vaginal fibroblasts for use in reconstructing pelvic ligaments.  Finally, faced with individuals that have lost a significant portion of functional vagina due to extirpative surgeries for pelvic cancers or chemotherapy and transgender patients needing a neovagina, the Moalli group is using a synthetic biology approach to vaginal biofabrication.  To do this, not only are they isolating and characterizing vaginal stem cell populations across the entire organ, but also developing interactive mechanical niches based on the structure and function of vaginal extracellular matrix.
