Data Science in 2025: Beyond the LLM Hype
In this episode, we chat about the current landscape of data science in 2025, looking beyond the headlines dominated by large language models. We see that while advances in the past five years in deep learning have led to new work in natural language processing and computer vision, tabular data analysis and classic machine learning remain a key part of the field. We also discuss the increasingly specialised roles within the data science ecosystem, talk about the evolving toolset that practitioners are using, and see which challenges face modern data science projects.
Our guest is Dr. Jodie Burchell is the Developer Advocate in Data Science at JetBrains. Jodie was previously a Lead Data Scientist at Verve Group Europe. She completed a PhD in clinical psychology and a postdoc in biostatistics, before leaving academia for a data science career. She has worked for 9 years as a data scientist in both Australia and Germany, developing a range of products including recommendation systems, analysis platforms, search engine improvements and audience profiling. She has held a broad range of responsibilities in her career, doing everything from data analytics to maintaining machine learning solutions in production.
