Welcome to Sample Space where the department of Statistical Science engages with the public to explore the subject and people of statistics.
Sample Space is a place where statisticians and everyone else can sample the world of statistics. Join us as we regularly share with you stories, insights and the tools to separate the signal from the noise. We do this in two formats:
- Magazine
- Podcast
Magazine
The Sample Space magazine in a newsletter that aims to keep our community of past and present students and staff in touch with what’s happening in Statistical Science at UCL.
Podcast
Hosted by members of the UCL Statistical Science department, the Sample Space podcast is a place where statisticians explore this fascinating subject.
Some episodes will take the form of interviews of members of the department, external speakers or students.
Other episodes will be more expository around particular projects, statistical ideas or talking points.
The podcast will showcase the amazing work in the department and in statistics generally to make the world a better place.

Statistical Developments in the Calculation of Value of Information
In this contributed interview from the Department of Statistical Science at UCL, we speak with a former member of the department, Dr Anna Heath. Dr Heath is currently a bio-statistician at SickKids hospital in Toronto within the Child Health Evaluative Sciences (CHES) program, and an assistant professor at the University of Toronto in the Dalla Lana School of Public Health.
We discussed with Anna about the application of health economic ideas to the conception, design and analysis of clinical trials, and in particular the concept of the Value of Information whereby we can quantify the economic value of obtaining information through research.

Bayesian predictive inference
In this contributed interview from the Department of Statistical Science at UCL, we speak with Professor Chris Holmes. Chris is Professor of Biostatistics at the departments of Statistics and the Nuffield Department of Medicine at the University of Oxford. He is also the Director for the Health Programme at the Alan Turing Institute. We discussed a recent presentation given at the department on Bayesian predictive inference and his involvement with statistical modelling to support the UK government’s COVID response.

Controlled backfill in oncology dose-finding trials
In this podcast we speak with Dr Hakim-Moulay Dehbi, who is currently Head of Statistics at the Comprehensive Clinical Trials Unit at UCL, about his last paper on controlled backfill in oncology dose-finding trials. He tells us about the motivation for this work, and more importantly how the interests of patients with cancer need to taken into account in dose-finding designs.

All of Machine Learning is now probabilistic
In a conversation with Kevin Murphy, the distinguished researcher at Google DeepMind, we explored his multifaceted career spanning academia and industry. Born in Ireland and educated at prestigious institutions in the UK and the US, Kevin's academic journey led him to become an associate professor in Canada, before transitioning to manage a research team at Google DeepMind in California.
We dived into the inspiration behind his acclaimed three books on "Probabilistic Machine Learning" and discussed some of the practical applications of his research. Kevin also offered valuable advice to early career researchers and Ph.D. students in Machine Learning.
