Bioengineering

REsearch Profile

I am a mechanical engineer enthusiastic about biomechanics. My investigation on biomechanics focuses on the effects that the surgical procedures have on joint kinematics. 

My research has been developed by implementing clinical cadaveric experiments and using Finite Element modelling of human joints. I have studied almost all the human joints including Shoulder, Elbow, Wrist, Spine, Hip and Knee. Other research areas of interest to me include medical devices, prosthetics design, and additive biomanufacturing.

Current Projects


Kinematic Analysis of the Knee with an injured PCL

Clinical study on changes of biomechanical changes of a knee with intact, full tear and reconstructed PCL ligament.

Scapholunate Ligament Reconstruction

Assessment of SL ligament reconstruction using CT-scan based Finite Element models to reproduce carpal kinematics

Carpal kinematics

The wrist can be classified into two types regarding the lunate bone shape. The effect of the bone geometry on the mechanics of the wrist is not wide explored. However, recent investigations have shown that carpal bones move differently during ulnar deviation in each type of wrist because of the interaction of the lunate with the adjacent bones.
