Amidst the COVID-19 pandemic, Sohini feels incredibly lucky to lead and have support from her amazing lab members, and is excited to see what scientific work and new lab members the future holds!

Cheng et al. is out in PLoS Genetics!    Jun 15, 2020

Graduate student Wei Cheng is first author on a paper out in PLoS Genetics, which is coadvised by our collaborator and CCMB colleague Lorin Crawford. This study entitled Estimation of non-null SNP effect size distributions enables the detection of enriched genes underlying complex traits releases our gene-level association test, gene-epsilon (pronounced “genie”), a new approach for identifying statistical associations between sets of variants and quantitative traits. Congratulations to all the authors!

McGuirl, Smith et al. is out in Genetics!    Jun 1, 2020

Graduate student Sam Smith is joint first author on a paper out in Genetics, which is a collaboration with Bjorn Sandstede’s group from the Division of Applied Mathematics at Brown University. This study entitled Hierarchical clustering of gene-level association statistics reveals shared and differential genetic architecture among traits in the UK Biobank releases WINGS, a method for clustering and prioritizing phenotypes based on shared genetic architecture revealed by gene-level association statistics. Congratulations to all the authors!

Introducing Dr. Shahamatdar!    Apr 1, 2020

This is no April Fool’s joke: Sahar defended her amazing dissertation entitled “Integrative Computational Approaches in Cancer Genomics” today! She is transitioning back to clinical rotations for her other doctorate (an MD from the Warren Alpert Medical School), and will be greatly missed. We were able to gather for a socially distant party to celebrate our latest lab graduate.

Shahamatdar et al. 2020 is out in Cell Reports!    Mar 3, 2020

MD/PhD student Sahar Shahamatdar’s first paper is out in Cell Reports, resulting from a collaboration with the Van Allen Lab at Dana-Farber Cancer Institute. In this study entitled Germline features associated with immune infiltration in solid tumors we identify germline variants, genes, & pathways associated with immune infiltration phenotypes in cancer. Congratulations to all the authors!

Palacios et al. 2019 is out in Genetics!    Nov 1, 2019

Have you ever thought “If only I could superexponentially reduce the state space of gene genealogies I’m dealing with when I infer changes in Ne over time!” ? Then this paper, releasing the method BESTT, is for you! Led by the incredible Julia Palacios, former lab postdoc, and building off of theoretical results from her 2015 Genetics paper. Currently for independent loci, but SMC-based inference is up next!

Musharoff et al. 2019 is out in PLoS Genetics!    Oct 25, 2019

We have a new paper out led by lab friend Shaila Musharoff in PLoS Genetics, entitled The inference of sex-biased human demography from whole-genome data. The paper releases a new method that uses comparisons of X-chromosomal versus autosomal genetic variation to infer sex-specific demographic parameters (see also Congratulations to all the authors, including collaborators Suyash Shringarpure and Carlos D. Bustamante!

Nakka et al. 2019 is out in AJHG!    Oct 10, 2019

The last chapter of Priyanka Nakka’s dissertation is now published in American Journal of Human Genetics, entitled Characterization of Prevalence and Health Consequences of Uniparental Disomy in Four Million Individuals from the General Population. Priya led this collaboration as an intern at 23andMe, Inc. The paper focuses on estimating, for the first time, the per-chromosome rates of uniparental disomy (inheriting both copies of a chromosome from just one biological parent) in samples from 23andMe and the UK Biobank. Our paper was also covered in The Atlantic by Sarah Zhang. This study underscores that recombination is simultaneously constrained but also variable and errors can sometimes be corrected. Most surprising, and exciting, for the lab was realizing that some people have incredibly long runs of homozygosity with no clear deleterious effect, an avenue we plan to continue pursuing.

Congratulations to all the authors, especially Dr. Nakka!

Coverage of SWIF(r) in Nature News!    Nov 1, 2018

SWIF(r) is discussed among other machine learning approaches to detect selection in genomes in this Nature News piece by Amy Maxmen!

New collaborative project with the Henn Lab is out in Cell!    Aug 2, 2018

A new paper the Ramachandran Lab collaborated on (Sohini and Julia Palacios are coauthors) is out in Cell, led by collaborators Elizabeth Atkinson and Brenna Henn! The paper is entitled “No Evidence for Recent Selection at FOXP2 among Diverse Human Populations”, and also involved Brown University colleagues Ashley Webb and postdoc Amanda Audesse. The work uses sequence data and diverse human samples to reanalyze so-called “language gene” FOXP2, previously thought to have undergone a selective sweep in the modern human lineage. We show that there is not evidence for this, revising the history of how humans acquired language. This work was funded by Sohini’s NIH R01 GM118652, on which Brenna is a co-investigator.

Other coverage of the paper can be found at Nature News and in Cell’s press release.

Congratulations to all the authors!

Kate Brunson joins the lab!    Jul 1, 2018

SMBE Satellite Meeting on aDNA begins!    Apr 4, 2018

Sohini and Emilia Huerta-Sanchez, who will be joining the Brown University faculty in Ecology and Evolutionary Biology and CCMB in July 2018, are the co-organizers of the Society of Molecular Biology and Evolution (SMBE) Satellite Meeting on Modern Methods for Study of Ancient DNA (4/4-4/7/2018) in Providence, RI. 60 participants from seven countries will arrive in Providence for an exciting lineup of talks and posters.

The main goal of the meeting is to bring together early career scientists (junior faculty, postdocs and graduate students) interested in discussing state-of-the-art methods and the challenges of studying population-genetic processes across time using ancient and extant DNA. As with most areas in genomics, this is one where there is an urgent need for new quantitative tools for analysis; we look forward to discussing the technical and methodological challenges facing population genetic researchers studying ancient DNA, as well as the ethics of data generation and of direct-to-consumer testing.

Two new papers out from the lab in Nature Communications and Philosophical Transactions of the Royal Society B!    Feb 19, 2018

Two new papers are out from the lab! Lauren’s amazing efforts led to SWIF(r)’s publication in Nature Communications; see news coverage at Brown for more details. This paper represents major progress on the research funded by our R01, furthers our collaboration with Brenna Henn (now at UC Davis) and recognizes contributions from former lab members Annie Fischer ‘17 and Stephen Rong. We are looking forward to seeing SWIF(r) - the sweep inference framework (controlling for correlation) - applied to classify adaptive mutations by our lab and others.

The second paper reviews the history of studies mapping genotypes to heritable phenotypes, by Marc Feldman and Sohini, out in Philosophical Transactions of the Royal Society B as part of a special issue entitle ‘Bridging cultural gaps: interdisciplinary studies in human cultural evolution’. The title of the paper is “Missing compared to what? Revisiting heritability, genes and culture”.

Congratulations to all the authors!

Priya's paper on gene networks underlying acute lymphoblastic leukemia is out in CEBP!    Oct 5, 2017

Priya’s second first-author paper is out in Cancer Epidemiology, Biology & Prevention. This paper furthers our collaboration with St. Jude Children’s Research Hospital, and begins our collaboration with Texas Children’s Hospital. The gene and network analyses presented uncover loci associated with acute lymphoblastic leukemia (ALL) that are missed by GWA studies. The paper also reports that ALL-associated loci do not appear to interact directly with each other to influence ALL risk, and instead appear to influence leukemogenesis through multiple, complex pathways.

Congratulations to all the authors!
