Statistical Machine Learning (SML) is the process of gaining understanding by constructing models of observed data with the intention to use them for prediction. SML plays a key role in many areas of science, finance and industry. In this project, we will use SML to design drug delivery particles of right size and low cytotoxicity. Size and drug loading are key factors that significantly influence the stability, effectiveness and cytotoxicity of drug delivery particles. However, the formulation and manufacturing of particles of right size and drug loading for drug delivery, as with other complex processes, often fail to be fully modelled by classical statistical techniques due to the non-linear relationships existing between components and/or processing conditions.
This project aims to construct fast and robust generative models for learning the relationship between drug loading (encapsulation efficiency), particle size (and its distribution), processing conditions (temperature, flow rate, drying), reactant type as well as components and properties (surface tension, viscosity and density) and different particle generation systems manufactured by Loughborough spinout company Micropore Technology Ltd. https://microporetech.com/.
Uncertainty Analysis (UA) implies how likely the particle size and drug loading is when the information of some other manufacturing factors are unknown. UA also provides practitioners the useful information of model transferability and generalisability when using the models for new data. This PhD will aim to also apply UA to understand and reduce the uncertainty in the proposed models by combining the data on drug loading efficiency and particle size to predict best methods of manufacturing to manufacture the particles of low cytotoxicity.
The student will gain experience and skills in a range of SML methods include Bayesian Predictive models, Neural Network, Robust Statistics for data with outliers, variable selection and model assessment methods. The student will also have opportunity to learn image analysis methods and tools to extract the information about the particle size and their uniformity from image data collected using various imaging modalities (optical and SEM microscopy for micron sized particles and TEM microscopy for nanosized particles).
The successful candidate will have at least a 2:1 BSc (Hons) in a relevant mathematical/statistical or computer science discipline.
