Thomas Nichols

Thomas Nichols

Thomas Nichols is a Wellcome Trust Senior Research Fellow in Basic Biomedical Science and the Professor of Neuroimaging Statistics at the Oxford Big Data Institute. He previously was a Professor in the Warwick Department of Statistics and WMG, and before that the Director of Modelling & Genetics at the GlaxoSmithKline Clinical Imaging Centre at Hammersmith Hospital in London, where he worked on statistical methods for fMRI in the context of clinical trials, and integrating genetic data into brain image analyses. Before coming to the UK he was an Associate Professor of Biostatistics at the University of Michigan, and in 2001 received his Ph.D. in statistics from Carnegie Mellon University where he also trained in cognitive neuroscience. He has been active in the field of functional neuroimaging since 1992, when he worked at the University of Pittsburgh’s PET Center as a programmer and statistician. Dr. Nichols’ research focuses on modelling and inference of neuroimaging data, including PET, fMRI & M/EEG. [CV]


Soroosh Afyouni

Soroosh Afyouni

Soroosh Afyouni is a postdoctoral research fellow at the University of Oxford. He is currently developing methods for threshold-free cluster enhancement (TFCE) method and multiple testing methods for neuroimaging data-sets. He has joined Oxford after undertaking an early career fellowship at the Warwick Institute of Advanced Study. In 2016, Soroosh received his PhD in Engineering from the University of Warwick where he developed methods for serial-correlation and Stochastic Block Modelling in functional connectivity of the human brain. In 2012, he received his Master of Engineering in Electronic Engineering from University of Birmingham where he worked on simulating the Spin-Echo sequences in Magnetic Resonance Imaging. Soroosh’s primary research interest is in functional connectivity and population connectomics.

Graduate Students

Marco Palma

Marco Palma

Marco Palma is a PhD student in Statistics at the University of Warwick on the OxWaSP CDT program, supervised by Thomas Nichols, Shahin Tavakoli and Julia Brettschneider. He is interested in developing high dimensional inferential methods for neuroimaging and is currently working on brain age estimation from structural imaging. He earned a Master’s degree in Statistical Sciences from the University of Bologna, with the final thesis written at LMU - Munich about regression models for multivariate functional data with application to brain images. In addition, as a student admitted to the Collegio Superiore in Bologna he had the opportunity to apply statistical methods in an interdisciplinary environment, working on several topics ranging from pain medicine to translation studies.

Tom Maullin

Tom Maullin

Tom Maullin is a DPhil student in the Big Data Institute at the University of Oxford. His research interests include distributed machine learning, developing data sharing techniques and random field theory. Previously, he has developed software packages for the displaying standardised neuroimaging results and the identifying of sources of bias and heterogeneity within an image based meta-analysis, as well as made additions to and maintained pre-existing software packages such as the SwE-toolbox.

Petya Kindalova

Petya Kindalova

Petya comes from Bulgaria where she attended the National High School of Mathematics and Natural Sciences. In 2011, Petya moved to Scotland to study at the University of Glasgow and in 2016 she successfully graduated Integrated Masters programme in Statistics with a year in industry. Working as an information analyst for a year in the National Health Service Scotland inspired her to do a DPhil in Statistics with application in public health. In particular, Petya is interested in Bayesian statistics and Genetics which led to her dissertation being focussed on identifying an appropriate model for correlated data suitable for data generated from experiments to study DNA methylation.

Sam Davenport

Sam Davenport

Sam Davenport is a PhD student at the University of Oxford on the OxWaSP Program, supervised by Thomas Nichols and Chris Holmes. Sam is currently working on Selective Inference methods to correct for bias in fMRI that arising due to the Winner’s Curse. He is also looking at methods for dealing with Missing Data. He did his undergraduate in Mathematics at Cambridge before going on to do the Part III mathematics masters course there specialising in Statistics. His masters dissertation was entitled “Statistical Analysis in Neuroimaging Structural Breaks” which involved identifying changes in the brain using bootstrapping techniques and looking at multiple hypothesis testing in tree structures.

Alex Bowring

Alex Bowring

Alex Bowring is a DPhil in Population Health student based in the Big Data Institute at the University of Oxford. His research is centred on functional MRI, with a particular focus on statistical methodology for neuroimaging analyses and developing open science practices. He is currently applying newly developed statistical methods to obtain precise confidence statements about where activation occurs in the brain for population neuroimaging studies, where thousands of subjects have been scanned. As well as this, he is also working on a software comparison project to understand the differences between the main neuroimaging software packages used for fMRI analyses.

Zhangdaihong (Jessie) Liu

Zhangdaihong (Jessie) Liu

Zhangdaihong (Jessie) Liu is a third year PhD student at the CDT of Mathematics for Real-world Systems at University of Warwick, and is currently a enrichment student working at the Alan Turing Institute. She is jointly supervised by Prof. Thomas Nichols and Prof. Jianfeng Feng. Jessie is currently working on linking brain connectivity, demographics and behaviour using HCP data. She completed the MathSys MSc in 2015. Before University of Warwick, she obtained a MSc in Mathematical Finance at Loughborough University and a BSc in Mathematics at Shandong University, China.


Simon Schwab

Simon Schwab is a Research Associate in the Department of Biostatistics with Prof. Leonhard Held at the Epidemiology, Biostatistics and Prevention Institute in Switzerland.
