In a world where data is more valuable than oil
, how can we use data to mitigate uncertainty when modelling complex physical systems? In my research, I tackle the problem of approximating high-dimensional models
with many input parameters. Through methods such as model-centric dimension reduction
and polynomial chaos expansions
, I investigate the application and synthesis of novel algorithms for turbomachinery design and manufacture
. We envision a day where systems as complex as an entire jet engine can be designed and monitored in real time with a digital twin
, powered not only by engineering knowledge but also constant learning through a data stream through a network of sensors.

Software Development Work
I am a software developer at Effective Quadratures
, an open-source Python
package for rapid computational studies including machine learning, uncertainty quantification and dimension reduction
(among many other features). I specialise in sparse regression, compressed sensing and dimension reduction. Visit our Discourse
