21 Mar 2013 Our paper describing the genetic variation of short insertions and deletions using sequencing data from the 1000 Genomes Project has been published by Genome Research

S. Montgomery, D. Goode, E. Kvikstad, C. Albers, Z. Zhang, X. Mu, G. Ananda, B. Howie, K. Karczewski, K. Smith, V. Anaya, R. Richardson, J. Davis, D. MacArthur, A. Sidow, L. Duret, M. Gerstein, K. Markova, J. Marchini, G. McVean and G. Lunter (2013) The origin, evolution and functional impact of short insertion-deletion variants identified in 179 human genomes. Genome Research doi: 10.1101/gr.148718.112

29 Dec 2012
Our paper describing the SHAPEIT (v2) method is now available from the Nature Methods website

O. Delaneau, J-F. Zagury and J. Marchini (2012) Improved whole chromosome phasing for disease and population genetic studies. Nature Methods 10, 5-6. + [Supplementary Material]

This paper presents a significantly new algorithm for haplotype estimation that combines together the best ideas from IMPUTE2 and SHAPEIT1. The new method clearly outperforms other existing methods in terms of phasing performance and is very competitive computationally.

6 Dec 2012 We have just released a new version of MULTIMIX (v1.1.0). This new version allows for missing data.

4 Dec 2012
We have just released a new versions of SHAPEIT (v2). The paper on this new version has now been accepted in Nature Methods and will appear soon.

10 Nov 2012
Olivier Delaneau has won a Charles Epstein Post-Doctoral Award (worth $2,000) at the ASHG conference in San Francisco for his work on SHAPEIT2. Well done Olivier! Androniki Menelaou made the final of the Pre-Doctoral competition (worth $1,000) but did not win a prize.


7 Nov 2012 Claire Churchhouse's paper has been published in Genetic Epidemiology

C. Churchhouse and J. Marchini (2012) Multiway Admixture Deconvolution Using Phased or Unphased Ancestral Panels. Genetic Epidemiology.

In this paper we develop a method for carrying out admixture deconvolution with more than two source ancestral populations. The method can handle both phased or unphased data from the source and/or sample populations. The method was used to analyze data from Phase 1 of the 1000 Genomes Project which was recently published in Nature. The MULTIMIX software implementing this approach will appear here soon.

1 November 2012
Jonathan Marchini has been awarded a Philip Leverhulme Prize

1 November 2012
The latest 1000 Genomes Project paper has been published in Nature today.

The 1000 Genomes Project Consortium (2012) An integrated map of genetic variation from 1,092 human genomes. Nature 491, 56-65.

This is a big international collaboration that has sort to sequence a large number of individuals from around the world with the aim of mapping the majority of the genetic variation with frequency above 1%. Members of our group that contributed to the analysis were Olivier Delaneau, Claire Churchhouse, Jason Liu and myself. The project has been reported in the mainstream press.

1 November 2012 The company Affymetrix has launched a new genotyping chip that was designed using our software IMPUTE2. They have issued a press release here giving the details.  http://phx.corporate-ir.net/phoenix.zhtml?c=116408&p=irol-newsArticle&ID=1752709

23 October 2012 Androniki Menelaou's paper
has been published in Bioinformatics.

A. Menelaou and J. Marchini (2012) Genotype calling and phasing using next-generation sequencing reads and a haplotype scaffold. Bioinformatics.

In this paper we show that combining low-coverage sequence data with microarray genotyping on the same subjects can lead to high quality haplotype reference sets that produce a notable boost in downstream imputation accuracy. The MVNcall software implementing this approach will appear here soon.

2 October 2012
Jared O'Connell won the poster prize at the recent Genomics of Common Diseases conference in Potomac, MD, USA.

27 August 2012
We have done very well this year with accepted talks at the American Society of Human Genetics meeting. Olivier Delaneau and Androniki Menelaou have made the final of the post-doctoral and pre-doctoral Charles J. Epstein Trainee Awards

24 August 2012
Claire Churchouse has succesfully passed her viva. Her thesis entitled 'Bayesian Methods for Estimating Human Ancestry Using Whole Genome SNP Data' was examined be Dr Lachlan Coin and Dr Simon Myers. Claire is now off to start a postdoc with David Althuler at the Broad Institute of Harvard and MIT. Good luck Claire!

22 July 2012
Our new paper (with Bryan Howie as co-lead author) on pre-phasing based imputation has now appeared in Nature Genetics.

Research

The main focus of my research is the development of statistical methods for the localization, detection and characterization of the genes that underly human disease. Some of the areas we are currently working on include
I am also interested in statistical image analysis and pattern recognition and have collaborated with the The Oxford Centre for Functional Magnetic Resonance Imaging of the Brain (FMRIB).

I currently hold an MRC New Investigator award.

VSO

Between September 1995 and September 1998 I worked as a VSO volunteer in Tanzania, teaching A-level Mathematics in a rural government run school near Iringa (map).

VSO enables men and women to work alongside people in poorer countries in order to share skills, build capabilities and promote international understanding and action, in the pursuit of a more equitable world.


If you are at all interested in applying to VSO and want to know more check out the webpage

are some pictures which I hope give you an idea of the time I spent in Tanzania.
