Verena Ruprecht, a group leader at Centre for Genomic Regulation in Barcelona, Spain, will speak on Cell and tissue mechano-plasticity in the early embryo. Her research focuses on morphogenesis, cell dynamics, mechanosensing, biological self-organization, and advanced fluorescence microscopy.
“When the life of a new organism starts, its body plan is built from a single, highly specialized cell, the fertilized egg. We are interested in understanding the dynamic cellular events of how a fertilized egg develops into an embryo of defined shape and functional multicellular organization. We study this ‘biological big bang’ from the perspective of physics and biology with the aim to identify mechanisms that control cell and tissue form and function, cellular and multi-cellular self-organization, and morphodynamic cell and tissue plasticity that ensures robust development in the presence of noise and errors.”

Alissa Richmond Armstrong, University of South Carolina, will speak on Nutrient Sensing Pathways Mediate Adipocyte to Ovary Communication in Drosophila. Her research focuses on: stem cells, development, oogenesis, signalling, and nutritional physiology.
“Organisms regularly experience changes in dietary input, therefore multiple organs must communicate to insure that an appropriate whole-organism response is mounted. The link between diet-induced obesity and several co-morbidities, including type 2 diabetes, cancers, and reproductive disorders, underscores the importance of understanding how adipose tissue communicates nutritional information to other organs. Using the power of Drosophila genetics, my research program investigates the molecular mechanisms employed by adipocytes to communicate dietary information to the stem cell-supported ovary. Currently, we are deciphering the nutrient sensing signalling pathways that function within adipocytes to regulate multiple aspects of oogenesis.”

Irene Miguel-Aliaga, MRC London Institute of Medical Sciences, Imperial College London, will speak on The Sex and Geometry of Inter-Cellular Communication. Her research focuses on: development, organ plasticity, organ shape, sex differences, and physiology.
“Our research explores the idiosyncrasies of adult organs: how they differ between the sexes or across life stages. Our work has revealed intestinal sex differences that impact food intake, gamete production and tumor susceptibility. Investigating how the intestine senses and responds to nutrients, we also discovered an intestinal zinc sensor that promotes Tor signalling to sustain food intake and developmental growth. We are now very interested in the idea that the three-dimensional arrangement of the intestine confines or enables its communication with other organs, and have developed new methods to describe and interrogate this new dimension to signalling.”

Rosie Alegado, University of Hawaiʻi, Mānoa, will speak on Microbial Ecology of an Indigenous Food System Facing Climate Change. Her research focuses on: microbial ecology, climate change, microbiome, and microbial diversity.
“Global climate change and the emergence of new infectious diseases are two of the most challenging problems our society has ever faced. Microbes are central to both, as they mediate ecosystem health at a wide range of scales spanning ocean basins to our own bodies. Yet, we have a limited understanding of how climate change will impact microorganisms, and little progress has been made to identify integrated and integral solutions to looming climate and disease threats. My group takes 2 approaches to addressing this gap: 1) utilizing baseline observational data to track ecological, taxonomic, and physiological changes in response to climate forcing; and 2) performing complementary experiments to quantify eco-evolutionary processes that underlie interacting ecological systems across trophic, spatial, and temporal scales.
Understanding this adaptability—which will determine how climate-driven changes in microbial diversity impact Earth systems from biogeochemical cycles to the distribution of microbial pathogens and transmission of human disease—is necessary for successful climate solutions.”

Raghu Padinjat, National Centre for Biological Sciences-TIFR, will speak on Spatial Organisation of Signalling Reactions in a Professional Sensory Neuron. His research focuses on: phosphoinositides, lipid transfer proteins, membrane contact sites, polarized cells, and sensory transduction.
“My scientific interest is understanding information transfer in cells. We study lipid signalling in cells and due to their hydrophobic nature, cells need to make special arrangements to move lipids between organelle membranes. Lipid transfer proteins working at membrane contact sites (MCS) have emerged as an exciting new organising principle for this purpose. However several key questions remain on the manner in which MCS are regulated in relation to the ongoing physiological needs of the cell. We study this problem using Drosophila photoreceptors as a model system.”

Monther Abu-Remaileh, Stanford University, will speak on The Biochemical Basis of the Lysosomal Dysfunction in Early-Onset Neurodegeneration. His research focuses on: lysosome, metabolism, and neurodegeneration.
“Lysosomal dysfunction has been implicated in a plethora of human diseases, however, the molecular basis of this dysfunction is yet to be discovered. Lysosomes are membrane-bound compartments that degrade macromolecules and clear damaged organelles to enable cellular adaptation to various metabolic states. Our lab studies how lysosomal pathways go awry in human diseases such as cancer and neurodegeneration, in order to develop new therapeutic modalities. To address these questions, we use multidisciplinary approaches, including metabolomics, proteomics and functional genomics, to study the biochemical functions of the lysosome in vitro and in vivo.”

Xiaofeng Wang, Virginia Tech, will speak on Protein and Membrane Interactions in Positive-Strand RNA Virus Genome Replication. His research focuses on: formation and function of membrane-bound viral replication complexes and development of mechanism-based antiviral strategies.
“… [My] research program focuses on finding conserved replication mechanisms used by plant and animal viruses. By understanding the common ways these viruses replicate, we can improve human health both directly through antiviral treatments and indirectly through increased food security. The positive-strand RNA [(+)RNA] genetic class of viruses notably include SARS-CoV2 and the majority of plant viruses. All members of this virus class assemble their viral replication complexes (VRCs) at specific organelle membranes, where viral replication protein(s) recruit host proteins and remodel membranes to form well-protected, membrane-bound VRCs. I am interested in mechanisms by which viral replication proteins are targeted to specific organelles, what host proteins are recruited to VRCs, and the lipid microenvironment of VRCs.”

Carrie Adler, Cornell University, will speak on Rewiring Death: Understanding the Circuitry Regulating DNA Damage and Apoptosis in Planarian Stem Cells. Her research focuses on: stem cell responses to injury, organ regeneration, chemotaxis and feeding behavior, and cellular responses to ionizing radiation.
“My lab studies stem cells and regeneration in planarian flatworms. Planarians are a classic model for studying regeneration, but more recently, pioneers in the field discovered that regeneration relies on an enormous population of stem cells. Upon injury, planarians can regenerate entire new animals by activating their stem cells and essentially rearranging the cells that make up their bodies. The stem cells, which comprise 20% of the animal’s body, are very nimble. Depending on what tissue has been damaged, they immediately begin producing the cells necessary to replace it. How this population of cells can collectively rebuild an entire animal is a mystery. Our long-term goal is to understand the signalling mechanisms that they use to initiate regeneration, sense injuries, and regulate cell division and and differentiation.”
