Probabilistic Modeling in Genomics 2016

12 Sep - 14 Sep 16

Organisers: Jonathan Marchini, University of Oxford, UK; Simon Myers, University of Oxford, UK; Jotun Hein, University of Oxford, UK; Peter Ralph, University of South California, USA

The 2nd Probabilistic Modeling in Genomics Conference (ProbGen16), was held at the Department of Statistics, University of Oxford, UK.

The conference covered probabilistic models, algorithms, and statistical methods across a broad range of applications in genetics and genomics. We invited abstract submissions on a range of topics including Population Genetics, Functional Genomics, Systems and Structural Biology, Methods for Genome-wide Association Studies, Causal inference in genetic studies, Assembly and Variant identification, Phylogenetics, Natural Selection and Quantitative Genetics.

Alongside invited speakers, oral presentations were selected from submitted abstracts. We particularly encouraged abstract submissions for oral and/or poster presentations from junior investigators, including postdoctoral fellows and graduate students.

This is an annual meeting, held at Cold Spring Harbor in 2015, and which evolved from the success of previous similarly-themed workshops held at the HHMI Janelia Farm Research Campus (2013) and Merton College, Oxford (2014).

The conference talks were held in the new Department of Statistics building in central Oxford, with conference accommodation across the road at Somerville College.

Keynote Speaker: Simon Tavare, Cancer Research UK Cambridge Institute, UK

Invited session chairs: Chiara Sabatti, Stanford, USA; Lior Pachter, Berkeley, USA; Maria De Iorio, UCL, UK; John Marioni, EMBL-EBI, Hinxton, UK; Ida Moltke, Copenhagen, Denmark.
