Johannes Daniel Scharwies
Basic Life Research Scientist
BioJohannes received his BSc from the Leibniz Universität Hannover (Germany) in Plant Biotechnology in the Fruit Science laboratory of Prof. Moritz Knoche. Inspired by research on water relations of fruit in the Knoche laboratory, Johannes joined the group of Prof. Stephen Tyerman at The University of Adelaide (Australia) with funding through the German Academic Exchange Service. Initially, his work focused on hydraulic properties of grape clusters for which he received his MSc in Agricultural Science. Afterwards, he joined the ARC Centre of Excellence in Plant Energy Biology through the Tyerman laboratory and specialised in molecular plant physiology by studying the role of aquaporins in plant responses to drought for a PhD. He investigated aquaporins, which are molecular channels in plant membranes that provide a gating mechanism for water fluxes and other small molecules, through a combination of gene expression analysis and utilization of transgenic overexpression and CRISPR-Cas9 knockout lines. His work was funded by the highly competitive Adelaide Scholarship International and a Supplementary Scholarship provided by the ARC Centre of Excellence in Plant Energy Biology. In April 2018, Johannes joined the laboratory of Prof. José Dinneny at Stanford University as a Postdoctoral Scholar.
Johannes' research focuses on plant hydraulics from a molecular scale up to whole plants. He is interested on how plants perceive and adapt to changes in the environment in particular related to water. This ranges from developmental decisions to molecular control of water movement, for example through aquaporins.
In the group of Prof. José Dinneny, he is investigating how lateral root branching responds to moisture availability, a phenomenon termed hydropatterning. He uses his expertise to design novel phenotyping systems to characterise lateral root branching across a wide range of diverse corn inbred lines. These technologies enable the use of population genetics approaches to detect genotype-phenotype associations with the aim to understand causal genetic variants and study how phenotypic plasticity is shaped through breeding. -

On Leave from 10/01/2024 To 12/31/2024Current Research and Scholarly InterestsThe goal of our research is to advance experimental paradigms for understanding normal cognitive and disease processes at the level of neural circuits, with emphasis on learning and memory processes. To advance these paradigms, we invent optical brain imaging techniques, several of which have been widely adopted. Our neuroscience studies combine these imaging innovations with behavioral, electrophysiological, optogenetic and computational methods, enabling a holistic approach to brain science.

Carla Shatz
Sapp Family Provostial Professor and Professor of Biology and of Neurobiology
On Leave from 09/01/2024 To 08/31/2025Current Research and Scholarly InterestsThe goal of research in the Shatz Laboratory is to discover how brain circuits are tuned up by experience during critical periods of development both before and after birth by elucidating cellular and molecular mechanisms that transform early fetal and neonatal brain circuits into mature connections. To discover mechanistic underpinnings of circuit tuning, the lab has conducted functional screens for genes regulated by neural activity and studied their function for vision, learning and memory.

Vincent V.C. Woo Director, Wu Tsai Neurosciences Institute, Frank Lee and Carol Hall Professor and Professor of Biology and of Pathology
Current Research and Scholarly InterestsThe connectivity of a neuron (its unique constellation of synaptic inputs and outputs) is essential for its function. Neuronal connections are made with exquisite accuracy between specific types of neurons. How each neuron finds its synaptic partners has been a central question in developmental neurobiology. We utilize the relatively simple nervous system of nematode C. elegans, to search for molecules that can specify synaptic connections and understand the molecular mechanisms of synaptic as

Jan Skotheim
Professor of Biology and, by courtesy, of Chemical and Systems Biology
Current Research and Scholarly InterestsMy overarching goal is to understand how cell growth triggers cell division. Linking growth to division is important because it allows cells to maintain specific size range to best perform their physiological functions. For example, red blood cells must be small enough to flow through small capillaries, whereas macrophages must be large enough to engulf pathogens. In addition to being important for normal cell and tissue physiology, the link between growth and division is misregulated in cancer.

Tim Stearns
Professor of Biology
Current Research and Scholarly InterestsWe use the tools of genetics, microscopy, and biochemistry to understand fundamental questions of cell biology: How are cells organized by the cytoskeleton? How do the centrosome and cilium control cell control cell signaling? How is cell division coordinated with duplication of the centrosome, and what goes wrong in cancer cells defective in this coordination?

Ayelet Voskoboynik
Assistant Professor (Research) of Biology
Current Research and Scholarly InterestsWe study the mechanisms by which animals differentiate between self and non-self, and how stem cells and immune cells coordinate to form tissues during development, regeneration, transplantation, and aging. By leveraging the natural stem cell-mediated development, regeneration, and chimerism in the colonial chordate Botryllus schlosseri, we investigate stem cell competition and the decline in regenerative capacity during aging.

Virginia Walbot
Professor of Biology, Emerita
Current Research and Scholarly InterestsOur current focus is on maize anther development to understand how cell fate is specified. We discovered that hypoxia triggers specification of the archesporial (pre-meiotic) cells, and that these cells secrete a small protein MAC1 that patterns the adjacent soma to differentiate as endothecial and secondary parietal cell types. We also discovered a novel class of small RNA: 21-nt and 24-nt phasiRNAs that are exceptionally abundant in anthers and exhibit strict spatiotemporal dynamics.

Dr. Zhiyong Wang
Professor (By Courtesy), Biology
BioDr. Wang is the acting director of the Department of Plant Biology, Carnegie Institution for Science, and a professor by courtesy of the Department of Biology, Stanford University. He is currently an associate editor of Molecular Cellular Proteomics, and editorial board member of Molecular Plant. He is a Fellow of the American Association for the Advancement of Science (AAAS) and recipient of the Humboldt Research Prize.
Dr. Wang obtained his Ph.D. in 1998 from UCLA, where he cloned the plant circadian clock gene CCA1. He did his postdoctoral research at the Salk Institute, where he studied the brassinosteroid signaling mechanism mediated by the BRI1 receptor kinase. Since joining Carnegie in 2001, his research has illustrated the receptor kinase signaling pathway that links the BRI1 receptor kinase to the BZR1 transcription factor and brassinosteroid-responsive genes in the Arabidopsis genome. He further demonstrated how the steroid signaling pathway integrates at the molecular level with other hormonal pathways, light signaling pathways, nutrient-sensing pathways, immunity pathways, and the circadian clock, to coordinately regulate plant growth and development. His lab uses combinations of genomic and proteomic approaches to understand how cellular signals are transduced and integrated through posttranslational modifications (e.g. phosphorylation and O-Glycosylation) and protein-protein interactions. His studies are elucidating the molecular mechanisms that control plant growth and mediate responses to environmental changes. -
