Research Summary

The primary focus of Dr. Moalli’s research has been on prolapse meshes – first defining their impact on the vagina and then transitioning to mechanisms of complications. Based on this knowledge, her group is developing novel elastomeric meshes whose properties more closely match those of the vagina. Recently, she has explored regenerative techniques to rebuild compromised vaginal supportive tissues. The strength of her research group is that it is highly interdisciplinary with expertise in biochemistry, biomechanics, computational analyses, and biomaterials. The expertise gained from this work has benefitted both the Urinary Incontinence Treatment Network and the Pelvic Floor Disorders Network. Currently, she is leading a national multicenter trial defining mechanisms of anterior vaginal wall failure following a native tissue versus a mesh-augmented repair of uterovaginal prolapse.
