Michael B. Elowitz is a biologist and professor of Biology, Bioengineering, and Applied Physics at the California Institute of Technology, [1] [2] [3] and investigator at the Howard Hughes Medical Institute. [4] In 2007 he was the recipient of the Genius grant, better known as the MacArthur Fellows Program for the design of a synthetic gene regulatory network, the Repressilator, which helped initiate the field of synthetic biology. [5] He was the first to show how inherently random effects, or 'noise', in gene expression could be detected and quantified in living cells, [6] leading to a growing recognition of the many roles that noise plays in living cells. His work in Synthetic Biology and Noise represent two foundations of the field of Systems Biology. Since then, his laboratory has contributed to the development of synthetic biological circuits that perform a range of functions inside cells, and revealed biological circuit design principles underlying epigenetic memory, cell fate control, cell-cell communication, and multicellular behaviors. [7]
His laboratory studies the dynamics of genetic circuits in individual living cells using synthetic biology, time-lapse microscopy, and mathematical modeling, with a particular focus on the way in which cells make use of noise to implement behaviors that would be difficult or impossible without it. Recently, his lab has expanded their approaches beyond bacteria to include eukaryotic and mammalian cells. [8]
Elowitz grew up in Los Angeles, California, where he attended the humanities magnet at Alexander Hamilton High School (Los Angeles). He studied Physics and graduated with a B.A. from the University of California, Berkeley in 1992, [9] and from Princeton University with a Ph.D. in 1999. [10] In 1997–1998, he spent one year at the European Molecular Biology Laboratory at Heidelberg. Afterwards, he was a postdoctoral fellow at the Rockefeller University in New York City.
While working as a graduate student at Princeton he co-authored songs such as Sunday at the Lab [11] with Uri Alon.

: CS1 maint: multiple names: authors list (link)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.

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. Typically, these circuits are categorized as either genetic circuits, RNA circuits, or protein circuits, depending on the types of biomolecule that interact to create the circuit's behavior. The applications of all three types of circuit range from simply inducing production to adding a measurable element, like green fluorescent protein, 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.

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.
