Modern Statistics for Interdisciplinary Omics and Big Data

The end of the IMforFUTURE project was celebrated with a final workshop focused on mathematical and statistical methodologies applied to omics research. This workshop was held online, from the 28th to the 30th of June 2021.

The workshop was a joint event of the IMforFUTURE network meeting and the Leeds Annual Statistical Research  (LASR) Workshop. There was also be a celebration of Kanti Mardia's 85th birthday.

We were pleased to have the following keynote speakers: Cornelia van Duijn, Hongzhe Li, and Janice Scealy.

The workshop also included a short course on omics integration in R and a mindfulness session on Zoom Fatigue.

Congratulations to Ruheyan Nuermaimaiti for winning the poster prize!

Hongzhe Li is a Professor in biostatistics, epidemiology, and informatics at the Perelman School of Medicine, University of Pennsylvania. He is the head of the Statistical Genetics and Genomics Laboratory. His research is mostly motivated by problems in statistical genetics and genomics, including methods for family-based genetic linkage and association analysis, methods for admixture mapping, methods for genome-wide association analysis, methods for analysis of microarray time course gene expression data, high dimensional regression analysis for genomic data, methods for copy number variation analysis, and methods for analysis of next generation sequence data. He has extensively published in both statistical methodological research in top statistics/biostatistics journals (JASA, AOS, AOAS, Biometrika, Biometrics, Biostatistics etc) and in top genetics journals (AJHG, Plos Genetics, etc) and collaborative research in top scientific journals (Science, NEJM, Nature, Nature Genetics, PNAS, Developmental Cell etc).

 

Janice Scealy is a senior lecturer of statistics at the Australian National University and a 2018 Australian Research Council Discovery Early Career Researcher Award Fellow. She was awarded a prominent research recognition - the Moran Medal in 2021 by the Australian Academy of Science for her substantial contributions to statistical science. Her research interests include: compositional data analysis; directional statistics, shape analysis and statistics for manifold valued data; robust statistics; model selection in linear mixed models; analysis of sample survey data; geostatistics; and analysis of spatial data.  Her work has been funded by multiple Australian Research Council programs. She has published in leading academic journals including Journal of the American Statistical Association, Journal of the Royal Statistical Society Series B, Australian and New Zealand Journal of Statistics, Statistics and Computing, and Statistical Science. She is currently a chief investigator on the Australian Research Council Discovery Project entitled A New Generation of Palaeomagnetic Statistics.

 

van duijnCornelia van Duijn is a Professor of epidemiology at Nuffield Department of Population Health and a Fellow of St Cross College, Oxford. Her research within the Oxford Big Data Institute focuses on large-scale –omics studies of neurodegenerative disorders. She also studies systemic vascular, endocrine and gastrointestinal pathology that is relevant for brain and ocular function. Her current research portfolio includes cross-omics research integrating (epi)genetic, transcriptomic, proteomic, metabolomic and microbiome data of epidemiological cohorts with state of the art brain imaging and cellular model systems. Over the  years,  she has been a leading figure in  several  international consortia  including  ENGAGE, CHARGE ,  IGAP,  ADSP  and  IGGC . At present, she is the leader of two major consortia: the Horizon2020 CoSTREAM consortium aiming to understand the link between stroke and Alzheimer disease and the MEMORABEL Gut-Brain consortium aiming to unravel the role of the gut microbiome in Alzheimer disease and brain pathology. She further leads the human proteomics and metabolomics discovery research in the Innovative Medicine Initiative (IMI) ADAPTED program, which aims to identify new Alzheimer medicines through understanding the function of the APOE gene.

R course on omics integration

This three-hour short course is aimed at researchers who want to learn how to jointly analyse two omics datasets and interpret the results. We will be using the “OmicsPLS” R package with real data examples.

The course consists of two parts. The first two-hour session is a mix of theory and practice. You will be introduced to the basics of data integration approaches and their sparse variants. We will also discuss how to incorporate external biological knowledge. You will practice with these approaches using OmicsPLS and try out different visualisation tools to interpret the results.

The second one-hour breakout session will be hands-on where you apply what you’ve learned to two omics datasets.

There will be a brief rejoinder at the end of the session.

By the end of this course, you should be able to:

  • Have a deeper understanding of data integration methods (PLS, O2PLS, GO2PLS)
  • Understand how feature selection works
  • Know how to incorporate external biological information
  • Implement O2PLS/GO2PLS on your own data with “OmicsPLS” R package
  • Interpret and visualise O2PLS/GO2PLS results
