CaSB@Yale brings together labs from across Yale, Emory University, and the University of Connecticut. Below, we list all of our center faculty, with links to visit their lab websites.

tes testAndre Levchenko, Ph.D.
Levchenko lab website

Dr. Andre Levchenko is the Principal Investigator of CaSB@Yale. He is the John C. Malone Professor of Biomedical Engineering at Yale and is also the Founding Director of Yale Systems Biology Institute (YSBI), whose major unifying activity will be centered on this Project. Dr. Levchenko has been the director of YSBI since Fall 2013, guiding it through a 2-fold expansion, consolidation in a new space, and establishment of vigorous research experience on a new campus. Dr. Levchenko is a systems biologist, bio-engineer, and biophysicist who has been among the active developers of Systems Biology as a discipline since its most recent emergence, and has made considerable impact on the integrative computational/experimental analysis of cellular signaling and cell-cell communication. His more recent efforts are in development of novel micro- and nano-fabricated devices for enhanced control of cellular micro-environments. His work on understanding of the innate immune response and mechanisms of cell migration has received wide acclaim (with the latter leading to his election as a Fellow of the American Physical Society earlier this year). His current focus is on understanding of the mechanisms of aggressive cell migration in diverse settings and in response to different cues. This research emphasis created the platform for unifying the efforts of multiple Yale researchers.

Murat Acar, Ph.D.
Acar lab website

Dr. Murat Acar is an Associate Professor in Molecular, Cellular and Developmental Biology and in Physics, and is a core faculty member of the Yale Systems Biology Institute. He is a systems biologist who combines experimental and computational tools in his research by using the budding yeast as a model organism. Trained as a physicist, Dr. Acar is interested in understanding and solving the complexity in the organization of natural gene networks by using a reductionist approach. Since even the most complex gene networks can be broken down to modular pieces operating as locally-embedded network motifs in the larger gene networks, Dr. Acar’s research aims to characterize the function and evolution of these frequently-occurring modular network motifs. He has many years of hands-on experience in yeast genetics, cell biology, and computational modeling. Dr. Acar will lead the research efforts aiming at characterizing the evolution of phenotypic switching rates in the yeast galactose network during cellular adaptation to fluctuating environments.

Rong Fan, Ph.D.
Fan lab website

Dr. Rong Fan is an Associate Professor of Biomedical Engineering and a microfabrication and microfluidics expert at Yale University. He was trained as an analytical and materials chemist before becoming a trainee of the NCI-founded Nano Systems Biology Cancer Center at Caltech, where he developed a high-density antibody barcode chip for multiplexed protein biomarker detection in microliters of blood or even single cells. His research interest is focused on the development of microfluidic systems and bioMEMS technology for multiparameter analysis of single cells and cell-cell paracrine signaling. His laboratory developed a high-throughput microchip technology for single cell, 42-plex cytokine profiling that was utilized to quantify the deep functional heterogeneity in human immune cells in response to pathogenic stimulation and in hematologic cancer cells. It was also used to quantify paracrine communication between cancer and immune cells. His laboratory is also working on the development of other microfluidic devices for single-cell functional genomics analysis tools (e.g., methylomics, transcriptomics, etc). He is the recipient of the Howard Temin Pathway to Independence award (K99/R00) from the National Cancer Institute, the NSF Early Stage Faculty Career Development (CAREER) Award and the Packard Fellowship for Science and Engineering.

Farren Isaacs, Ph.D.
Isaacs lab website

Dr. Isaacs is an Associate Professor in the Department of Molecular, Cellular and Developmental Biology and a core faculty member in the Systems Biology Institute at Yale. He is a synthetic biologist focused on developing foundational genomic and cellular engineering technologies to understand and engineer biological systems. His lab integrates engineering and evolution through the construction of genes, networks and genomes alongside quantitative models to gain a better understanding of biological systems. In turn, they utilize these insights to program and evolve organisms with new biological function. A particular emphasis is the development of genome engineering technologies to construct ‘Genomically Recoded Organisms’ that possess an alternate genetic code. In the context of CaSB@Yale, re-coded organisms improve properties for incorporating nonstandard amino acids into proteins, including the site-specific incorporation of phosphoserine to activate human kinases in engineered bacteria. Dr. Isaacs’ work focuses on incorporating phosphorylated amino acids to enable the production of active kinases implicated in the tumorigenesis of glioblastomas. These efforts will be extended in three key areas: (1) to recapitulate phosphorylation-based mammalian signaling in recoded bacteria, (2) to elucidate biomolecular interactions of kinase functions, and (3) will be leveraged to identify novel inhibitors of kinase activity.

Mark Lemmon, Ph.D.
Lemmon lab website

Dr. Mark Lemmon is a cellular and molecular biologist and pharmacologist, is Co-Director of the Yale Cancer Biology Institute, and David A. Sackler Professor of Pharmacology. The Lemmon laboratory has made significant contributions to understanding molecular mechanisms of cellular signaling by growth factor receptor tyrosine kinases – notably the EGF receptor – and through lipid second messengers, notably the phosphoinositides and other anionic lipids that bind pleckstrin homology (PH), FYVE, KA1, and other domains. The Lemmon lab made highly significant and high impact contributions to the structural understanding of both of these phenomena, and to understanding these signaling axes from structural/mechanistic perspectives – combining cellular, biochemical, structural, and (increasingly) organismal studies. Recently, a key goal of the laboratory has been to understand how mutational alterations of receptor tyrosine kinases, in particular the therapeutic targets EGFR and ALK, lead to aberrant signaling and cancer – and how this information can be used to impact clinical approaches (through direct collaboration with clinicians). The goal is to bring more biochemistry to personalized medicine in oncology. Another key aim of work of the Lemmon laboratory is to understand signaling systems and networks more broadly by studying the signaling consequences of molecular perturbations that are well defined (through the lab’s in vitro and structural work). This has been applied to studies of the role of the EGF receptor in Drosophila development, and is now being pursued in several cancer cell contexts.

Michael Murrell, Ph.D.
Murrell lab website

Dr. Michael Murrell, an Assistant Professor in the Department of Biomedical Engineering and a core faculty member in the Systems Biology Institute at Yale, is a biophysicist whose primary expertise is in mechanical force production in cell biology. His laboratory develops approaches to understanding mechanical force generation by two distinct but complementary approaches. First, he measures the mechanical stresses produced by living cells subject to genetic and pharmacological perturbation. In doing so, he identifies how the dynamics and composition of the cell cytoskeleton and cell membrane influence the generation and transmission of mechanical stresses to the extracellular matrix. In parallel, he designs and engineers artificial cells in vitro, using purified proteins and lipids to reconstruct the cell cytoskeleton and membrane, for the goal of reproducing force production in a simplified system. As there are few components, and no biochemical regulation, this allows him to isolate the role of individual components, whose abundance and activity can be easily manipulated. To this end, Dr. Murrell has developed precise control of physical variables that can influence the generation and transmission of mechanical stresses, including cell volume, F-actin organization, membrane tension, fluid pressure and adhesion. From this, his lab learns basic physical principles regarding how cells produce mechanical force, which may otherwise be obfuscated by the overlapping biochemical and genetic regulation that exits in living cells. Thus, their simplified systems can inform us as to the basic physical relationships that underlie mechanical force production in cells, as well as provide potential targets for genetic and pharmacological perturbations. Dr. Murrell will seek to identify the role of NKCC1 in mediating mechanical force production in invasive glioblastoma and melanoma cells, by exploring its role in coupling to the cytoskeleton, as well as modulating fluid flow, hydrostatic pressure, and the volume of the cell.

Jesse Rinehart, Ph.D.
Rinehart lab website

Dr. Jesse Rinehart is an Assistant Professor in the Department of Cellular & Molecular Physiology at the Yale University School of Medicine and also a core faculty member in the Yale Systems Biology Institute. He is a physiologist and proteomics expert. Dr. Rinehart studied protein synthesis and the evolution of the genetic code during his graduate work and completed his postdoctoral training focused on protein phosphorylation in physiological systems. Dr. Rinehart’s research aims to understand and “decode” complex signaling networks in physiological systems. Researchers in the Rinehart laboratory use an innovative combination of quantitative phosphoproteomics and synthetic biology to achieve their aims. They are now applying this technology to understand the properties of phosphoserine in human kinases and singling networks. Dr. Rinehart’s team will deploy these enabling technologies to advance our understanding of how kinases control aggressive cancers and specifically to identify small molecule kinase inhibitors to target human cancers.

Günter Wagner, Ph.D.
Wagner lab website

Dr. Günter Wagner is an evolutionary biologist studying the evolution of the mammalian female reproductive tract, and other aspects of the evolution of development. He is Alison Richard Professor of Ecology and Evolutionary Biology and a core faculty member in the Yale Systems Biology Institute. His laboratory focuses on the evolution of gene regulation and the evolutionary origin of the uterine decidual cell, a cell type critical for the implantation of the fetus and the maintenance of pregnancy. One of the main functions of the decidual cell is to regulate the invasion of the fetal trophoblast and thus the regulation of invasive behavior. Last year Dr. Wagner, together with a student Alaric D’Souza, published a paper that documented a correlation between the (secondary) evolution of non-invasive placentation and a lower rate of malignancy in certain forms of cancer. This observation motivates his participation CaSB@Yale, where he will investigate the mechanisms by which endometrial stromal cells oppose the invasion of the fetus and how, in bovines and related species, this may also have conveyed resistance to melanoma malignancy.
