A generegulatory network (GRN) is a collection of molecular regulators that interact with each other and with other substances in the cell to govern the gene expression levels of mRNA and proteins which, in turn, determine the function of the cell. GRN also play a central role in morphogenesis, the creation of body structures, which in turn is central to evolutionary developmental biology (evo-devo).
Synthetic biology (SynBio) is a multidisciplinary field of science that focuses on living systems and organisms, and it applies engineering principles to develop new biological parts, devices, and systems or to redesign existing systems found in nature.
Modelling biological systems is a significant task of systems biology and mathematical biology. Computational systems biology aims to develop and use efficient algorithms, data structures, visualization and communication tools with the goal of computer modelling of biological systems. It involves the use of computer simulations of biological systems, including cellular subsystems, to both analyze and visualize the complex connections of these cellular processes.
Pamela Ann Silver is an American cell and systems biologist and a bioengineer. She holds the Elliot T. and Onie H. Adams Professorship of Biochemistry and Systems Biology at Harvard Medical School in the Department of Systems Biology. Silver is one of the founding Core Faculty Members of the Wyss Institute for Biologically Inspired Engineering at Harvard University.
The repressilator is a genetic regulatory network consisting of at least one feedback loop with at least three genes, each expressing a protein that represses the next gene in the loop. In biological research, repressilators have been used to build cellular models and understand cell function. There are both artificial and naturally-occurring repressilators. Recently, the naturally-occurring repressilator clock gene circuit in Arabidopsis thaliana and mammalian systems have been studied.
James Joseph Collins is an American bioengineer who serves as the Termeer Professor of Medical Engineering & Science at the Massachusetts Institute of Technology (MIT). Collins conducted research showing that artificial intelligence (AI) approaches can be used to discover novel antibiotics, such as halicin and abaucin. He serves as the Director of the Antibiotics-AI Project at MIT, which is supported by The Audacious Project, and is the faculty lead for life sciences at the MIT Jameel Clinic.
Christopher Voigt is an American synthetic biologist, molecular biophysicist, and engineer.
Alexander van Oudenaarden is a Dutch biophysicist and systems biologist. He is a leading researcher in stem cell biology, specialising in single cell techniques. In 2012 he started as director of the Hubrecht Institute and was awarded three times an ERC Advanced Grant, in 2012, 2017, and 2022. He was awarded the Spinoza Prize in 2017.
Dame Caroline Dean is a British plant scientist working at the John Innes Centre. She is focused on understanding the molecular controls used by plants to seasonally judge when to flower. She is specifically interested in vernalisation — the acceleration of flowering in plants by exposure to periods of prolonged cold. She has also been on the Life Sciences jury for the Infosys Prize from 2018.
The International Human Frontier Science Program Organization (HFSPO) is a non-profit organization, based in Strasbourg, France, that funds basic research in life sciences. The organization implements the Human Frontier Science Program (HFSP) and is supported by 14 countries and the European Commission. Shigekazu Nagata is the HFSPO President and Chair of the Board of Trustees since 2018.
Uri Alon is a Professor and Systems Biologist at the Weizmann Institute of Science. His highly cited research investigates gene expression, network motifs and the design principles of biological networks in Escherichia coli and other organisms using both computational biology and traditional experimental wet laboratory techniques.
Cellular noise is random variability in quantities arising in cellular biology. For example, cells which are genetically identical, even within the same tissue, are often observed to have different expression levels of proteins, different sizes and structures. These apparently random differences can have important biological and medical consequences.
Johan Paulsson is a Swedish mathematician and systems biologist at Harvard Medical School. He is a leading researcher in systems biology and stochastic processes, specializing in stochasticity in gene networks and plasmid reproduction.
Synthetic biological circuits are an application of synthetic biology where biological parts inside a cell are designed to perform logical functions mimicking those observed in electronic circuits. The applications range from simply inducing production to adding a measurable element, like GFP, to an existing natural biological circuit, to implementing completely new systems of many parts.
Wendell Lim is an American biochemist who is the Byer's Distinguished Professor of Cellular and Molecular Pharmacology at the University of California, San Francisco. He is the director of the UCSF Cell Design Institute. He earned his A.B. in chemistry from Harvard University working with Jeremy Knowles on enzyme evolutionary optimization. He obtained his Ph.D in biochemistry and biophysics from Massachusetts Institute of Technology under the guidance of Bob Sauer using genetic and biophysical approaches to understand the role of hydrophobic core interactions in protein folding. He then did his postdoctoral work with Frederic Richards at Yale University on the structure of protein interaction domains. Lim's work has focused on cell signaling, synthetic biology, and cell engineering, particularly in immune cells.
Stanislas Leibler is a French–American theoretical and experimental biologist and physicist. He is Systems Biology Professor at the Institute for Advanced Study in Princeton and the Gladys T. Perkin Professor and Head of the Laboratory of Living Matter at the Rockefeller University.
In systems biology, live single-cell imaging is a live-cell imaging technique that combines traditional live-cell imaging and time-lapse microscopy techniques with automated cell tracking and feature extraction, drawing many techniques from high-content screening. It is used to study signalling dynamics and behaviour in populations of individual living cells. Live single-cell studies can reveal key behaviours that would otherwise be masked in population averaging experiments such as western blots.
Galit Lahav is an Israeli-American systems biologist and Professor of Systems Biology at Harvard Medical School. In 2018 she became Chair of the Department of Systems Biology at Harvard Medical School. She is known for discovering the pulsatile behavior of the tumor suppressor protein p53 and uncovering its significance for cell fate, and for her contributions to the culture of mentoring in science. She lives in Boston, Massachusetts.
Genetic regulatory circuits is a concept that evolved from the Operon Model discovered by François Jacob and Jacques Monod. They are functional clusters of genes that impact each other's expression through inducible transcription factors and cis-regulatory elements.
Eileen E. M. Furlong is an Irish molecular biologist working in the fields of transcription, chromatin biology, developmental biology and genomics. She is known for her work in understanding how the genome is regulated, in particular to how developmental enhancers function, how they interact within three dimensional chromatin topologies and how they drive cell fate decisions during embryogenesis. She is Head of the Department of Genome Biology at the European Molecular Biology Laboratory (EMBL). Furlong was elected a member of the European Molecular Biology Organization (EMBO) in 2013, the Academia Europaea in 2016 and to EMBO’s research council in 2018.
