Research Interests

The ultimate goal of my research is to develop novel strategies to diagnose, treat and prevent surgical site infection following orthopedic surgery.


Initially, I am using synovial fluid and tissue samples collected from canine clinical patients with bone and joint infection in order to characterise the bacterial contamination and then identify sensitive and specific markers for the diagnostic purpose.


On the other hand I’m testing the bacterial resistance, mechanical and osseointegrative properties of novel surface-engineered orthopaedic implants via a combination of in-vitro and in-vivo studies.


The in vitro evaluative assays are based on bacterial-implant biomaterial and osteoblasts-implant biomaterial interactions. While the in vivo study is based on using a rabbit animal model and the evaluation is going to be performed via Micro CT, histomorphometry, destructive mechanical testing and quantitative bacterial burden count after implant sonication. 


Eventually, by developing an orthopaedic implant material that is able to resist the postoperative infection while at the same time support osseointegration and bone apposition, will  make surgeries safer and more cost effective which in turn is going to increase the spectrum of the healthcare users with almost the same settled budget.
