About
About me.
I am a final-year Biomedical Engineering student with an interest in medical-device development, testing and research.
My main strengths are analysing technical data, checking whether a design meets its requirements and explaining what the results do and do not show.
The OpenSim project shows my biomechanics and MATLAB experience. The shaft project shows mechanical calculations and ANSYS. The hydrogel dressing update shows how I would apply design controls, risk management and regulation to a medical device.
Skills
Tools and methods
Technical skills.
Methods I have applied through biomechanics, mechanical design and medical-device development work.
MATLAB and data analysis
Imported, cropped, normalised, averaged and plotted nine trials so the three walking conditions could be compared consistently.
MATLABData processingVisualisation
Project evidence →Mechanical design and FEA
Used hand calculations, material selection and ANSYS static structural analysis to assess a cross-trainer shaft.
ANSYSCADMeshingStress analysis
Project evidence →Medical-device development
Applied user needs, House of Quality, FMEA, verification planning and the Australian regulatory pathway to a proposed wound-dressing update.

Selected case studies
Selected projects.
Work across human movement, mechanical validation and medical-device development. Each case study covers the process, findings and what I would improve.

Restricted-knee gait analysis
We used a knee brace, motion capture and force plates to examine how restricted knee flexion changed lower-limb movement and loading. I processed nine trials through OpenSim and MATLAB.
Key findingPeak right-knee flexion reduced by about 10°, with demand redistributed across the hips and opposite limb.
My contribution: equal contribution across design, data collection, processing, interpretation and reporting.

Cross-trainer shaft validation
I sized and specified a stepped steel shaft, then used static structural FEA to assess stress and deformation under the stated operating load.
Key findingMaximum stress was 51.85 MPa and predicted deformation was 23.8 μm.
My contribution: shaft sizing, feature specification, material selection and ANSYS analysis.

Responsive hydrogel dressing update
I developed a hypothetical update to an existing sterile hydrogel dressing by adding a fibre-reinforced responsive layer and planning the design, risk and regulatory pathway.
Project outcomeA defined device concept with a staged evidence plan and clear safety boundaries.
Status: concept proposal based on an ARTG-included sterile hydrogel dressing; it has not been built or clinically tested.

Beyond the case studies
Experience and development.
Research, teamwork and practical work have shaped how I approach technical problems.
Experimental research
Developing and testing a moisture-responsive hydrogel-fibre actuator has improved my planning, record keeping and ability to separate preliminary results from supported conclusions.
Linked skills → experimental work, materials and technical reportingTeamwork and technical communication
The OpenSim and shaft projects required shared responsibilities, review of other members' work and consistent reporting across different technical sections.
Linked skills → teamwork, peer review and accountabilityWorking under pressure
Progressing from bartender to pizza chef at The Fraternity Club has developed my ability to prioritise tasks, follow safety procedures and communicate clearly during busy service.
