About

I actually did my PhD in fraud detection through the lens of machine learning and data science. It was like being a detective in a world of data, with each anomaly and pattern a potential clue.

Post-PhD, I've been keen to apply my knowledge in fresh and exciting ways. Currently, I'm engrossed in the world of change point detection algorithms. It's all about finding that precise moment when the routine becomes the unusual - a concept that echoes my fraud detection roots.

On top of this, I've been delving into the fascinating domain of AI-based test selection. It involves leveraging AI to analyze historical data and code changes, thereby selecting the most relevant tests likely to uncover potential issues. This allows teams to focus their testing efforts where they are likely to have the most impact, saving time and resources while still maintaining high software quality.
