Stef Garasto

Dr Stef Garasto BSc, MSc, PhD

Senior Lecturer in Data Science (AI and Ethics)

Stef Garasto is a Senior Lecturer in Data Science at the University of Greenwich, with a focus on machine learning, participatory approaches to data science, and the ethics of algorithmic systems.

Prior to joining Greenwich, Stef worked a researcher at Imperial College London and at Nesta. As a Principal Researcher in Data Science at Nesta, they used novel sources of data and machine learning algorithms with a view to building a more resilient and inclusive labour market. This included developing measures of jobs accessibility and skill demand using a variety of datasets.

Stef obtained a PhD in Computational Neuroscience from Imperial College London. Their PhD research focused on stimulus reconstruction methods to investigate how the brain processes sensory information (specifically vision) and population coding principles.

Research / Scholarly interests

My research falls under the umbrella of applied data science, primarily using machine learning and participatory approaches. I use computational techniques to derive insights about systems - whether societal, biological or algorithmic - while seeking to make use of data and algorithms in a way that centres the communities most affected by them.
