Today, in addition to working with his research team, he is also the Research Director of the Facility for Electron Microscopy Research (FEMR).

    Talk Summary: Regulatory mechanisms in specialized ribosomes in neurons. Ribosomes are cellular machines that translate the genetic code to make proteins in all types of cells. In neurons, this process needs special regulation so that proteins are made at the synapse, a critical connecting point between neurons. In my talk, I will describe how neuronal ribosomes have essential differences from ribosomes in other cells. In neurons, the ribosomes possess a unique “pause” button. This button allows them to stop the production of proteins temporarily during the transport of this machinery to the synapse and then restart production at the synapse when the proteins are needed. Our recent work shows that this pause button is distinct to neuronal ribosomes. Identifying these regulatory mechanisms is helping to understand protein synthesis in neurons and the impact of this process on memory mechanisms and neurodevelopment disorders.

  • Dr. Joshua Milstein

    Dr. Joshua Milstein

    Department of Physics - University of Toronto

    Dr Joshua Milstein is an Associate Professor of Physics at the University of Toronto. His laboratory employs biophysical and computational techniques to address unanswered questions in the biological sciences. These efforts range from developing single-molecule localization microscopy, to quantify the abundance and stoichiometry of proteins and nucleic acids within cells, to combining microfluidics with computational microscopy and machine learning, to study the competitive population dynamics and ecology of bacterial communities.

    Talk Summary: Multi-species populations of bacteria are often found within confined and densely packed environments where competition for space largely determines the ecological diversity of the microbial community. The role of mechanical interactions, between cells and their confining environment, in shaping the ecology of the resulting communities is still poorly understood. We have been performing single-cell measurements of a model, dual-species system of bacteria competing within engineered microchannels that, when combined with simulations and models of the population dynamics, provide fundamental insight into the dynamics of tightly confined microbial systems.

    Talk Summary: Single particle electron cryomicroscopy (cryo-EM) has evolved from a technique capable only of low-resolution insight into molecular structure into what is now often the most straightforward method for determining high-resolution structures of macromolecules and macromolecular assemblies. Canadian scientists have made important contributions to this field from its beginning, and there are now many laboratories around the country using this technology. In this talk I will outline the growth of cryo-EM in Canada. I will discuss the state-of-the-art and some new approaches using the cryo-EM with examples from my own laboratory.

    Talk Summary: X-ray computed tomography (XCT) generates 3D images of biological specimens at multiple scales from a stack of radiographic images obtained while rotating the sample. Advantages include the large penetration depth, the scalable field of view and corresponding resolution from below 1 μm up to 1 mm. Also, it requires minimal sample preparation and is noninvasive, thus enabling non-destructive and live imaging. Because X-ray attenuation depends on density, the technique is particularly suited to plant specimens because of the omnipresence of intercellular air spaces in many plant organs. In this presentation I will give an overview of the principles of XCT and the available instruments and image processing software. I will illustrate the technique based on some examples from plant science including plant development and organ morphogenesis, as well as modeling of transport processes in plants. Finally, I will introduce emerging topics such as phase contrast, multispectral, dark-field and time-resolved imaging and challenges such as the management of large amount of 3D image data and open access databases.

    Talk Summary: Living specimens are both animate and three-dimensional. Lattice Light Sheet Microscopy (LLSM) utilizes optically structured beams to perform fast 3D imaging of dynamic processes in vivo with improved resolution and beam uniformity. I will provide updates on our work to develop self-driving light sheet microscopes that can autonomously capture rare events of interest and on our efforts to apply light sheet microscopes together with single-molecule imaging to understand the relationship between chromatin architecture and nuclear functions.

Artificial Intelligence Session

  • Dr. Flavie Lavoie-Cardinal

    Dr. Flavie Lavoie-Cardinal

    Université Laval

    Dr. Lavoie-Cardinal is an is an Associate Professor to the Department of Psychiatry and Neuroscience at Université Laval, Québec, Canada, and a NSERC Tier 2 Canadian Research Chair in Intelligent Nanoscopy of Cellular Plasticity. She is also a principal investigator at the CERVO Brain Research Center and the Health and Life Science research axis leader at the Institute for Intelligence and Data in Québec city. She obtained her PhD in Chemistry in 2011, followed by two postdoctoral fellowships, one of which was in the group of Prof. Dr. Dr. Stefan Hell (2014 Chemistry Nobel Prize) on the development of super-resolution microscopy techniques. She now leads a research group of 23 graduate and undergraduate students working the interface of optical microscopy, neuroscience and artificial intelligence (AI). Her transdisciplinary research program aims at developing novel AI-assisted bioimaging strategies to uncover the molecular signature of altered synaptic plasticity, leading to neurodegeration or cognitive impairment.

    Talk Summary: Understanding the molecular mechanisms underlying synaptic transmission is challenging in part because synapses are tiny (less than a micron), exhibit a wide range of shapes and internal structures, undergo activity-dependent plasticity, and their molecular components are dynamic. Optical nanoscopy allows us to characterize the molecular dynamics and interactions of synaptic proteins at their scale: the nanoscale. Developing machine learning-assisted frameworks for optical nanoscopy allows real-time optimization of multi-modal live-cell imaging at the nanoscale as well as for quantitative high throughput super-resolution image analysis. We have developed machine and deep learning approaches for: 1) quantitative analysis of neuronal protein organization in optical nanoscopy images, and 2) the optimization of image acquisition schemes, especially in living neuronal samples. We integrate automated deep learning-based analysis strategies, machine learning-assisted optimization approaches, and generative deep neural networks in the acquisition loop of optical super-resolution microscopes to guide the image acquisition process and reduce the light exposition on the sample. This allows us to perform time-lapse imaging of protein reorganization at the nanoscale in living cultured neurons. The development of data-driven microscopy is transforming our ability to discover and characterize rare phenomena that may influence synaptic connections and thus to discover new mechanisms influencing the proper functioning of our
