Current Ph.D. students (main supervisor):
- Luke Smallman (Oct 2015 – Mar 2019): Luke began working with me in the summer of 2014 as the recipient of a London Mathematical Society Undergraduate Research Bursary (LMS URB). His work on reweighted algorithms of SVM to treat the imbalance of slices in the SDR framework was published in Communications in Statistics – Theory and Methods. Following this, when funding became available (through funding given to us kindly by Prof. Paul Harper) to study his Ph.D. on topics related to dimension reduction for text data he started his Ph.D. on Oct 2015. Initially in his supervisory team was Dr. Jennifer Morgan (currently with NHS Delivery Unit in Bridgend) and after her departure Prof. Paul Harper joined the supervisory team. During his Ph.D. he has focused on sparse exponential family PCA algorithms (with a focus in the Poisson distribution due to its direct application to the analysis of text data). On this topic he has published one paper (Pattern Recognition 2018) and one was accepted in Computational Statistics (May 2019). In his final part of his Ph.D. Luke workes on a unified framework for the development of exponential family PCA algorithms and another one on the asymptotic properties of estimating estimations relating to PCA. Luke submitted in Sept 2019 and he had his viva in Dec 2019 (Examiners: Dr. Ioannis Kosmidis (Warwick) and Dr. Jonathan Gillard (Cardiff)). He is currently working on the changes with a deadline in March 2020. We are currently working on a submitting a few of the last ideas in his Ph.D. work. Since Aug 2019 he works as a Data Analyst in Admiral.
- Hayley Randall (Oct 2016 – Mar 2020): Hayley is funded by EPSRC funding to the School and she applied to do a Ph.D. in my group after taking a 3rd year module on Multivariate Statistics. Her second supervisor is Dr. Jonathan Gillard. She is interested in Dimension Reduction for high-dimensional problems (large p and either large n (n>p) or small n (p>n)). We submitted our first paper in May 2019 (a collaboration with Dr. Xingye Qiao at Binhampton University) and she started working currently on her second paper.
- Benjamin Jones (Oct 2016 – Mar 2020): Ben is funded by EPSRC fundig to the School and he applied to do a Ph.D. in my group. His background was in Pure Maths and therefore we decided to take advantage of his knowledge in that area and do some work with functional and kernel Principal Component Analysis (FPCA and KPCA). His second supervisor is Prof. Karl-Michael Schmidt. He has published one paper on the predicting potential of FPCA in a regression setting (Annals of the Institute of Statistical Mathematics – 2018 (online)) and one on the predictive potential of KPCA (Electronic Journal of Statistics – 2020). He is currently working on methodological work for dimension reduction methods on the presence of categorical predictors.
- Alya Alzahrani (July 2019 – Dec 2022): Alya joined the school and she is self funded. She is interested to work in envelope models and she is currently reading the literature on envelope models.
Current Ph.D. students (co-supervisor):
- Paul Robinson (Biosciences – Oct 2017 – part time): Paul asked me to co-supervise his Ph.D. in Biosciences. He is interested in modelling bird species in Sierra Leone forests and he is currently at the sampling stage.
- Ross Burton (Medical School – Oct 2018 – Mar 2022): Ross is working on applications of Machine Learning techniques to analyze and classify sepsis patients. He is the first Ph.D. student in my collaboration with Prof. Matthias Eberl in the Medical School.
- Oliwia Michalak (Medical School – Oct 2018 Mar 2022): Oliwia was the recipient of GW4 funding to support her research which also includes a CASE conversion. She is the second Ph.D. student in my collaboration with Prof. Matthias Eberl and her primary supervisor is Dr. Tom Pembroke. She is working on applying machine learning techniques on patients with liver diseases.
In addition to these, I am a member of the supervisory team of Mr. Kimon Ntotsis, a Ph.D. candidate at the Department of Mathematics, University of Aegean. Kimon started his Ph.D. in January 2019 and we are working on robust dimension reduction methodology.
