I am a Lecturer of Machine Learning and Data Science at 麻豆传媒, UK. My area of research is Responsible Artificial Intelligence (RAI), with a focus on algorithmic fairness and transparency. I have developed interpretable preprocessing methods to ensure distributive fairness in datasets, as well as a hybrid method to ensure fairness and data anonymisation. Currently I'm researching how to metricise and visualise procedural fairness. I am interested in interdisciplinary collaborations, particularly with people from the healthcare sector, but I'm open to collaborations in other research areas as well.

Most of my research has been on fairness, privacy and transparency for ML, nowadays referred to as Responsible AI (RAI). Specifically, I have designed algorithms that optimise group fairness for classification tasks through data preprocessing.

Some of my most relevant papers are:

I have lectured since 2012, teaching the following subjects:

• Computing: Introductory Programming, Python Fundamentals, and Python for Research and Education
• Data Science: Data Analysis, Data Visualisation, and Machine Learning
• Mathematics: Calculus, Linear Algebra, Graph Theory, Logic, Statistics, and Operations Research

Next semester, I will be teaching Machine Learning for the Computer Science undergraduate program, as well as for the Degree Aprenticeship in Data Science program.
