CMG_Data GSP_All Fwd: Announcement of the 2018 Conference of the Program in Quantitative Genomics: “B iobanks: Study Design and Data Analysis”

The GSP Analysis Centers co-organized the 2018 Harvard Program in Quantitative Genomics Conference on Biobanks: Study Design and Data Analysis. See https://www.hsph.harvard.edu/2018-pqg-conference/. Below is the conference announcement. The GSP investigators are welcome to attend it if interested.

Biobanks: Study Design and Data Analysis

November 1-2, 2018
Harvard Medical School Conference Center | Boston, MA

The impetus for the 2018 Conference of the Program in Quantitative Genomics of Harvard T.H. Chan School of Public Health comes from the proliferation of large scale biobanks worldwide. Biobanks are composed of massive genetic and genomic data, epidemiological data, Electronic Medical Records, wearable devices and imaging data. Examples of large biobanks include UK Biobank, China Kadoorie Biobank, eMERGE, Finland Biobank, Million Veteran Program, and MyCode Project of the Geisinger Health System, among others. The use of biobanks is becoming an essential and potentially revolutionary approach to biomedical research, with the capacity to improve the prevention, diagnosis, and treatment of a wide range of illnesses, and to advance personalized health. To take full advantage of the enormous opportunities presented in biobanks, there is an urgent need for discussing important quantitative issues, leveraging interdisciplinary expertise, and designing studies with increased scale and power. This conference aims at discussing several key quantitative challenges in biobank studies, including designing biobanks to meet a wide array of needs, developing strategies for improving phenotyping accuracy, harmonizing data across biobanks, and developing analytic methods for biobank data.

The conference will be centered on the following three topics:

SESSION 1: Types of Biobanks
SESSION 2: Biobank Data Analysis
SESSION 3: Phenotyping and Harmonization Across Biobanks

Keynote Speakers:
Tianxi Cai Harvard T.H. Chan School of Public Health
Gil McVean Oxford University
Catherine Sudlow UK Biobank, University of Edinburgh

Distinguished Speakers:
Zhengming Chen China Kadoorie Biobank, Oxford University
Kelly Cho Brigham and Women’s Hospital, Harvard Medical School Joshua Denny Vanderbilt University
David Ledbettter Geisinger Health System
Seunggeun Shawn Lee University of Michigan
Shawn Murphy Massachusetts General Hospital, Harvard Medical School Benjamin Neale Massachusetts General Hospital, Harvard Medical School Samuli Ripatti University of Helsinki, Institute for Molecular Medicine Finland (FIMM)
Manuel Rivas Stanford University

The conference program includes time for scientific presentations and a poster session and reception for submitted abstracts. Please visit the conference website for more details.

Registration + travel awards will be provided to support junior researchers who submit abstracts.
*Three abstracts will be selected to be presented as 10-minute platform talks

Statseminars Stat & Data Science Seminar, Speaker Carl Zimmer 4/27 @ 11am-1pm

Title: The Library of Babel: On Trying to Read My Genome

Information and Abstract:

Applied Data Science Seminar. Not long ago, information about our DNA was virtually impossible to gain. Now, thanks to the falling cost of DNA sequencing and the growing power of bioinformatics, genetic information is undergoing a Gutenberg-scale explosion of popularity. Millions of people are paying for DNA tests from companies like 23andMe and Ancestry.com, and they are getting unprecedented amounts of information about their ancestry and hereditary diseases. For my latest book, “She Has Her Mother’s Laugh,” I got my genome sequenced and enlisted scientists at Yale and elsewhere to help me interpret it. In my talk, I’ll discuss the results of that exploration–at once enlightening and baffling

Title: “Learning and Geometry for Stochastic Dynamical Systems in high dimensions”


We discuss geometry-based statistical learning techniques for performing model reduction and modeling of certain classes of stochastic high-dimensional dynamical systems. We consider two complementary settings. In the first one, we are given long
trajectories of a system, e.g. from molecular dynamics, and we estimate, in a robust fashion, an effective number of degrees of freedom of the system, which may vary in the state space of then system, and a local scale where the dynamics is well-approximated by a reduced dynamics with a small number of degrees of freedom. We then use these ideas to produce an approximation to the generator of the system and obtain, via eigenfunctions of an empirical Fokker-Planck equation (constructed from data), reaction coordinates for the system that capture the large time behavior of the dynamics. We present various examples from molecular dynamics illustrating these ideas.

In the second setting we only have access to a (large number of expensive) simulators that can return short paths of the stochastic system, and introduce a statistical learning framework for estimating local approximations to the system, that can be (automatically) pieced together to form a fast global reduced model for the system, called ATLAS. ATLAS is guaranteed to be accurate (in the sense of producing stochastic paths whose distribution is close to that of paths generated by the original system) not only at small time scales, but also at large time scales, under suitable assumptions on the dynamics. We discuss applications to homogenization of rough diffusions in low and high dimensions, as well as relatively simple systems with separations of time scales, and deterministic chaotic systems in high-dimensions, that are well-approximated by stochastic
diffusion-like equations.

Title: On Spectral Graph Clustering

Abstract: Clustering is a many-splendored thing. As the ill-defined cousin of classification, in which the observation to be classified X comes with a true but unobserved class label Y, clustering is concerned with coherently grouping observations without any explicit concept of true groupings. Spectral graph clustering — clustering the vertices of a graph based on their spectral embedding — is all the rage, and recent theoretical results provide new understanding of the problem and solutions. In particular, we reset the field of spectral graph clustering, demonstrating that spectral graph clustering should not be thought of as kmeans clustering composed with Laplacian spectral embedding, but rather Gaussian mixture model (GMM) clustering composed with either Laplacian or Adjacency spectral embedding (LSE or ASE); in the context of the stochastic blockmodel (SBM), we use eigenvector CLTs & Chernoff analysis to show that (1) GMM dominates kmeans and (2) neither LSE nor ASE dominates, and we present an LSE vs ASE characterization in terms of affinity vs core-periphery SBMs. Along the way, we describe our recent asymptotic efficiency results, as well as an interesting twist on the eigenvector CLT when the block connectivity probability matrix is not positive semidefinite. (And, time permitting, we will touch on essential results using the matrix two-to-infinity norm.) We conclude with a ‘Two Truths’ LSE vs ASE spectral graph clustering result — necessarily including model selection for both embedding dimension & number of clusters — convincingly illustrated via an exciting new diffusion MRI connectome data set: different embedding methods yield different clustering results, with one (ASE) capturing gray matter/white matter separation and the other (LSE) capturing left hemisphere/right hemisphere characterization.

NIMH Virtual Workshop on Quantum Computing



March 28, 2018

9:00 am – 1:00 pm EST

Goal of the workshop

This virtual workshop aims to highlight core computational problems faced by genetics and the subdomains of neuroscience that parallel or quantum computing can address. By bringing together experts in quantum and parallel computing with experts in genetics and neuroscience, we hope to start a dialogue between academic and industry partners working in this area with the focus on algorithm optimization and development. This virtual workshop will be the forum and the nexus to find convergence between cross-disciplinary fields that are operating mostly independently – 1) genomics and neuroscience, and 2) AI/machine learning and 3) quantum computing. The goal is to identify key avenues for computation optimization via parallel and quantum algorithms. This workshop will facilitate the use of state-of-art computational technologies for addressing core bottlenecks in genomics and neuroscience.


This workshop will cover the following topics with 5 minutes break following each topic discussion:

  • Opening Remarks (10 min)
