Giammaria Giuliani Immunohistology Laboratory

The HSS Research Institute Histopathology Service provides efficient, high-quality, and cost-effective histological and immunohistochemical services to the HSS research community to outside investigators. Our primary purpose is to facilitate the use of histological and immunohistochemical techniques as reliable research tools for the investigation of autoimmune, inflammatory and orthopedic diseases that fall under the mission and expertise of the Hospital for Special Surgery. 

The facility includes shared equipment that is available exclusively to trained HSS staff. Both HSS and outside investigators are welcome to request services. Work is done in a fee-for-service basis with a graded fee structure. Priority use and reduced fees are given to HSS affiliated investigators.


Co-Directors: Miguel Otero, PhD (OteroM@hss.edu) and Kyung-Hyun Park-Min, PhD (ParkminK@hss.edu)
