The Simons Center for Quantitative Biology (SCQB) is Cold Spring Harbor Laboratory’s home for mathematical, computational, and theoretical research in biology. Research at the SCQB focuses broadly on revealing how genomes work, how they evolve, and what makes them go wrong in disease. Members of the SCQB also develop computational tools and genomic technologies that are broadly useful to the community.
The SCQB is supported by a generous endowment from the Simons Foundation. Additional funding has been provided by the Starr Foundation and Lavinia and Landon Clay.
We are a growing group with positions at various levels.
Simons Center for Quantitative Biology Annual Reports
Our faculty are experts in the mathematical and physical sciences who address open problems in biology, often in close collaboration with experimentalists. Most research in the center falls in the general areas of gene regulation, evolutionary genomics, disease-related human genomics, and genomic technology development. However, our work also touches on neuroscience, immunology, and plant biology, among other fields.
Members of the SCQB maintain close collaborative ties across CSHL and with many other New York area groups, including Stony Brook University and the New York Genome Center.

As data generation has grown increasingly efficient and inexpensive, the interpretation of large data sets has emerged as a limiting step for advances in biology. Researchers at the SCQB aim to make sense of this “big data” through the development of innovative modeling, algorithmic, and machine-learning methods, drawing broadly from techniques in mathematics, computer science, and physics. Research in the center is diverse but is permeated by the following four major themes: Gene Regulation, Evolutionary Genomics, Genomic Disease Research, and Genomic Technology.
Kinney and McCandlish are interested in developing both theoretical and experimental methods, along with computational and mathematical tools, for elucidating the relationship between biological sequences and biological functions ranging from gene expression to protein function.
Hammell studies several topics related to gene regulation, including the behavior of small non-coding RNAs, inference of gene regulatory networks, and the impact of transposable elements on gene expression. She has also developed methods for the analysis of single-cell RNA-seq data.
Siepel is broadly interested in modeling the regulation of gene expression in mammals, ranging from transcription factor binding and chromatin accessibility, to transcription initiation and elongation, to the determination of RNA stability.
Meyer studies central T cell tolerance induction and gene regulation in the thymus. Her work combines genomics studies with in silico models to understand the fundamental principles of thymus biology.
Koo studies the functional impact of genomic mutations through a computational lens using data-driven machine learning solutions. He is broadly interested in applications for studying gene regulation and protein (dys) function.
McCandlish develops theory and mathematics to address a number of open questions in evolutionary genetics, including the dynamics of evolution when mutation is rate-limiting or exhibits biased patterns, and the evolutionary implications of epistasis, i.e. interactions between mutations or genes.
Siepel uses evolutionary methods to identify regulatory elements, to reconstruct early human history, including interbreeding events with Neandertals, and to estimate the fitness consequences of new mutations in the human genome. He is also applying similar methods to agriculturally important plants such as maize and rice.
In addition, Iossifov uses evolutionary signatures to aid in the identification of genes associated with autism spectrum disorder, and Krasnitz uses phylogenetic methods to study the evolution of tumors.
Navlakha works at the interface of theoretical computer science, machine learning, and systems biology. He primarily studies how collections of molecules, cells, and organisms process information and solve interesting computational problems critical for survival.
Genomic Disease Research
Iossifov aims to understand the genetics of autism spectrum disorder (ASD) through the analysis of large genomic data sets, in close collaboration with Mike Wigler’s research group and the New York Genome Center.
Krasnitz develops mathematical and statistical tools to characterize the cellular composition, genomic disruptions, evolutionary history, and invasive capacity of malignant tumors, often in collaboration with clinical oncologists.
Hammell studies the role of transposable element activation in neurodegenerative diseases, particularly amyotrophic lateral sclerosis (ALS) and fronto-temporal dementia (FTD).
Genomic Technology Development
Kinney is a pioneer in the development of massively parallel reporter assays for characterizing the relationship between regulatory sequences and gene expression, including both transcription and RNA splicing.
More detailed information about research at the SCQB is available from the faculty websites of the SCQB members and associate members.
In addition to its research activities, the SCQB serves as a hub for education, training and research in the quantitative life sciences.

To ensure that cells function normally, tens of thousands of genes must be turned on or off together. To do this, regulatory molecules—transcription factors and non-coding RNAs—simultaneously control hundreds of genes. My group studies how the resulting gene networks function and how they can be compromised in aging associated diseases, such as neurodegeneration and cancer.
Every gene has a job to do, but genes rarely act alone. Biologists have built models of molecular interaction networks that represent the complex relationships between thousands of different genes. I am using computational approaches to help define these relationships, work that is helping us to understand the causes of common diseases including autism, bipolar disorder, and cancer.
Research in the Kinney Lab combines mathematical theory, machine learning, and experiments in an effort to illuminate how cells control their genes. These efforts are advancing the fundamental understanding of biology and biophysics, as well as accelerating the discovery of new treatments for cancer and other diseases.
Deep learning has the potential to make a significant impact in basic biology and cancer, but a major challenge is understanding the reasons behind their predictions. My research develops methods to interpret this powerful class of black box models, with a goal of elucidating data-driven insights into the underlying mechanisms of sequence-function relationships.
Many types of cancer display bewildering intra-tumor heterogeneity on a cellular and molecular level, with aggressive malignant cell populations found alongside normal tissue and infiltrating immune cells. I am developing mathematical and statistical tools to disentangle tumor cell population structure, enabling an earlier and more accurate diagnosis of the disease and better-informed clinical decisions.
We have recently come to appreciate that many unrelated diseases, such as autism, congenital heart disease and cancer, are derived from rare and unique mutations, many of which are not inherited but instead occur spontaneously. I am generating algorithms to analyze massive datasets comprising thousands of affected families to identify disease-causing mutations.
Some mutations are harmful but others are benign. How can we predict the effects of mutations, both singly and in combination? Using data from experiments that simultaneously measure the effects of thousands of mutations, I develop computational tools to predict the functional impact of mutations and apply these tools to problems in protein design, molecular evolution, and cancer.
A properly functioning immune system must be able to recognize diseased cells and foreign invaders among the multitude of healthy cells in the body. This ability is essential to both prevent autoimmune diseases and fight infections and cancer. We study how a specific type of immune cells, known as T cells, are educated to make this distinction during development.
Biological systems must solve problems to survive, and their solutions can be viewed as “algorithms.” Our goal is to uncover these algorithms, translate them to improve computer science, and use them to spark new hypotheses about biological function and dysfunction.
I am a computer scientist who is fascinated by the challenge of making sense of vast quantities of genetic data. My research group focuses in particular on questions involving molecular evolution and transcriptional regulation, with applications to cancer and other diseases as well as to plant breeding and agriculture.
