Profile / 01

An engineer who connects physics, evidence and implementation.

My work spans the full engineering loop: define the question, build or instrument the model, test sensitivity, compare with evidence, quantify the remaining error, and communicate the decision without hiding uncertainty.

That approach links my current MSc projects in Denmark with earlier marine work in Bangladesh, where I supported construction inspection, commissioning and acceptance testing across major dredger programmes.

LES and RANS hub-height velocity-deficit contours for a six-turbine wind-farm layout01

Individual project - Wind energy

Wind-farm wake modelling, validated against LES

Built three six-turbine actuator-disk cases in OpenFOAM and quantified where steady RANS is reliable - and where it becomes non-conservative for dense aligned arrays.

Engineering outcome

The staggered layout reached a row-power RMSE of 0.037, while the 5D aligned layout rose to 0.083 because RANS recovered the wake too quickly.

Four post-test steel surfaces comparing acceptable and material-removal conditions02

Team of 2 - Industry-linked R&D

Food-grade grease benchmarking for robot gears

Planned and executed 23 ball-on-disc trials on a Bruker UMT TriboLab, then built one consistent Python workflow for run-in removal, friction statistics and stability screening.

Engineering outcome

The strongest food-grade case reached mean COF 0.0946 at 2.0% CV. Surface evidence still prevented a premature replacement approval based on friction alone.

Bar charts comparing storage revenue, annualised cost and levelised cost of storage03

Team of 3 - Energy systems

European power-system storage analysis

Evaluated 13 PyPSA scenarios across battery, hydrogen and combined storage under a common nuclear cap and progressively tighter carbon limits.

Engineering outcome

Hydrogen cut annual system cost by EUR 14.44 billion, reduced curtailment from 109.15 to 0.03 TWh/year and eliminated load shedding in the reference setting.

Finite-element mesh and von Mises stress contour for a hanger bracket04

Team project - Computational mechanics

Reliability-oriented structural analysis

Automated a parameterised ANSYS model through pyMAPDL, generated a 15-point central composite design and fitted a quadratic surrogate for reliability assessment.

Engineering outcome

Monte Carlo evaluation found no samples above the 50 MPa yield criterion within the investigated geometry and loading range.

COMSOL stress distributions for long and short sandwich-composite beam specimens05

Team project - Test-to-model correlation

Reverse engineering a sandwich composite

Combined microscopy, two-span three-point bending, inverse sandwich theory and COMSOL solid/shell models to identify effective material properties.

Engineering outcome

Estimated a 66.39 GPa face modulus and 146 MPa core shear modulus; the long-span shell model matched the measured force within -0.08%.

German day-ahead electricity price series used in an hourly Power-to-X dispatch model06

Individual project - Sector coupling

Power-to-X waste heat for district heating

Modelled a 100 MW electrolyser, methanation unit and heat pump over 1,440 winter hours using German day-ahead electricity prices.

Engineering outcome

A climate-first strategy delivered 89,561 MWh of heat and avoided 17,733 t CO2; a EUR 39.3/MWh break-even rule instead produced a EUR 0.55 million operating profit.

MSc thesis in progress

Tribological evaluation of food-grade grease for industrial robot reduction gears

The thesis builds on an industry-linked 23-test screening campaign. The next research step is to move from friction stability alone toward repeatability, quantitative wear and application-relevant validation.

Research questions
  • When does a stable friction trace conceal unacceptable surface damage?
  • How should short laboratory tests be translated into a defensible gear-lubricant decision?
  • Which wear measurements and repeat tests are necessary before substitution?

Research interests
  • Tribology and application-led lubricant validation
  • CFD, wake modelling and model-form uncertainty
  • Experimental mechanics and test-to-model correlation
  • Reliability, uncertainty and data-driven engineering
