Polycyclic aromatic compounds and other air toxics: toward understanding the whole air pollutant mixture.

Air quality issues have traditionally been divided between common air pollutants like ozone and contaminants such as polycyclic aromatic compounds (PACs). Research has tended to be conducted by experts who are largely separated, who publish in different journals and attend different conferences. Environmental management has been distinct as well, with national programs and international agreements designed and implemented by different groups for ‘smog’ and ‘contaminants’. More recently, air quality research and management have begun to acknowledge that exposure and effects are affected by the simultaneous presence of multiple pollutants.  The whole air pollutant mixture has not yet been well-characterized at any location. Canadian efforts associated with PACs, air toxics and the urban air pollution mixture will be discussed to demonstrate how we can begin to better understand ambient air and its overall impacts on human health and the environment.

As machine learning and physical modeling technologies are reaching maturity, a new era of technological innovation in computer-driven drug discovery is dawning. In this talk, we highlight an exciting new generation of tools that blend machine learning with physical modeling to accelerate structure-enabled drug discovery programs, with the goal of ultimately enabling fully autonomous drug discovery. We also highlight the role these tools have played in the COVID Moonshot, an open science global collaborative effort to discover a novel patent-free oral SARSCoV-2 antiviral with the goal of rapid, global, and equitable access.

John Chodera’s research focuses on reimagining the way we develop small molecule drugs and pair therapeutics with individual patient tumors by bringing physical modeling and structure-informed machine learning into the cancer genomics era. By combining novel algorithmic advances to achieve orders-of-magnitude efficiency gains with powerful but inexpensive GPU hardware, machine learning, and distributed computing technologies, the Chodera lab is developing next-generation approaches and open source software for predicting small molecule binding affinities, designing small molecules with desired properties, predicting drug sensitivity or resistance of clinical mutations, and understanding the detailed structural mechanisms underlying oncogenic mutations. The Chodera lab co-develops the OpenMM GPU-powered molecular simulation framework, which powers numerous biomolecular modeling and simulation applications using physical modeling and machine learning. As a core member of the Folding@home Consortium, the lab harnesses the largest computing platform in the world—the first to reach an exaFLOP/s—pooling the efforts of a million volunteers around the world to study functional implications of mutations and new opportunities for therapeutic design against cancer targets and global pandemics. Dr. Chodera co-founded the Open Force Field Initiative, a scientific collaboration funded by the NIH and an industry consortium consisting of dozens of scientists working to develop modern open source infrastructure for building and applying high-quality biomolecular force fields. Dr. Chodera is a co-founder of the COVID Moonshot, a radical open science patent-free drug discovery effort aiming to develop an inexpensive small molecule therapy effective against COVID-19 and future coronavirus. Using automated biophysical measurements, the Chodera laboratory collects new experimental data targeted to advance the quantitative accuracy of our methodologies, and gather new insight into drug susceptibility and resistance in kinases and other cancer targets. Their work makes extensive use of scalable Bayesian statistical inference, machine learning via probabilistic programming, and information theoretic principles for designing experiments and quantifying error. Dr. Chodera is passionate about open science, disseminating scientific best practices, and maximizing research reproducibility

Prineha Narang, Harvard

Host: Prof. Frank Gu

Quantum systems host spectacular nonequilibrium effects and unconventional transport phenomena, but many of these remain challenging to predict and consequently, technologically unexplored. My group’s research focuses on how quantum systems behave, particularly away from equilibrium, and how we can harness emergent effects in these systems. By creating predictive theoretical and computational approaches to study dynamics, decoherence and correlations in molecules and materials, our work enables technologies that are inherently more powerful than their classical counterparts, ranging from scalable quantum information processing to ultra-high efficiency optoelectronic and energy conversion systems. Capturing these phenomena poses unique computational and theoretical challenges. In fact, the simultaneous contributions of processes that occur on many time and length-scales has eluded state-of-the-art computational physics and model Hamiltonian approaches alike, necessitating a new lens. In this context, I will focus on our work on approaches to describe excited-states in quantum matter, including electron-electron and electron-phonon interactions beyond leading order, and predicting emergent states introduced by external drives. Our approach brings quantum chemistry, quantum optics and condensed matter together to create unexpected and useful properties, including surprisingly long coherence times and propagation lengths, as well as enabling new quantum probes of correlations. I will also discuss our methods in spatially-resolved non-equilibrium transport in quantum matter. By introducing GPU-accelerated large-scale transport frameworks that retain microscopic scattering, we are overcoming long-standing barriers in the field and taking transport in matter to exascale computing. Finally, I will share our vision for the future towards crossing the finite-extended system divide, and leveraging the power of both classical high-performance computing and quantum computation paradigms in predicting new phenomena.

Abstract

Functional foods deliver health benefits beyond basic nutrition. Natural health product (NHP) is the Canadian regulatory term for over-the-counter supplements that contain health-promoting molecules derived from foods, e.g., vitamins, minerals, herbals, probiotics. Together, these product categories encompass so much of the science and technology surrounding foods and nutrition. Our group works at the food-nutrition interface to support the evidence-basis for a variety of functional foods and NHPs. We have specialized interests in dietary lipids and in understanding how the structure of foods and food ingredients influences bioavailability and metabolic response, mediated by events in the gastrointestinal tract.

For example, what role does triacylglycerol crystallinity play in determining postprandial lipemia and what does this mean for saturated fatty acids? This talk will discuss our application of in vitro digestion and human research methods to relate emulsion properties to gastric microstructure, emptying, and postprandial satiety and lipemia (a risk factor for cardiometabolic diseases) to highlight the benefits of integrated food-nutrition research. Examples drawing on other functional foods will also be presented. Foods have always been functional. Focusing specifically on food structure and applying a physical property lens to what happens in the gastrointestinal tract paves the way for better understanding the nuanced relationships between foods and health, and ultimately to realize the potential for efficacious functional foods and NHPs.

Bridging the gap between microbiology and chemistry in built environments

Prof. Sarah Haines, Assistant Professor
Department of Civil & Mineral Engineering
University of Toronto

We spend the majority of our time indoors where the built environment has important implications for human health, particularly for those with asthma. Asthma disproportionately impacts low-socioeconomic communities due to poor quality housing associated with mold and moisture exposure. One of the main exposures to mold in housing is through the resuspension of floor dust. Microbes grow in carpet dust at elevated relative humidity conditions and release microbial volatile organic compounds (mVOCs). However, we do not know how the influence of moisture may drive species composition and chemical emissions from microbes in dust and on common building materials. Understanding
these interactions in the indoor environment is the next frontier in environmental engineering and has the potential to lead to substantial improvements in public health.

Utilizing cutting edge techniques, my work has ranged from collecting dust in carpet from homes in Ohio to analyzing dust particles from the International Space Station. Ultimately, results from my work have demonstrated that microbial growth can be quantitatively modeled in buildings, and for the first time demonstrated interactions between chemicals and microbes in house dust under elevated relative humidity conditions. My future work will link climate change, social justice, and viruses to contribute to healthy indoor environments.

Desmond Moser, Western

Host: Prof. Jane Howe

The characterization of long-lived minerals, including natural metal deposits of copper, and their corrosion behaviours is an area of shared interest among geo- and materials scientists. This is particularly true in regard to transdisciplinary efforts to improve the design of multi-barrier Deep Geological Repositories for spent nuclear fuel. Examples of our application of micro- and nano-characterization techniques (e.g. EBSD, SIMS, Atom Probe Tomography) will be presented for a range of geomaterials including > 4 billion-year-old weakly-radioactive minerals in Martian meteorites and 1 billion-year-old copper from Earth.

_____________________________________

Professor Desmond Moser has spent most of his career unraveling the evolution of ancient planetary crusts using weakly radioactive and highly resilient microminerals. Increasingly his group is directing their expertise to help understand all aspects of the long-lived natural materials important to designing multi-barrier Deep Geological Repositories for spent nuclear fuel.

Prof. Moser conducts solid Earth and planetary science research using Western’s nationally unique Zircon and Accessory Phase Laboratory (ZAPLab). Micromineral crystal growth and deformation analysis (e.g. CL, EBSD) is integrated with field mapping, microchemical (EDS, WDS), petrologic and mass spectrometry measurements (radiogenic and stable isotopes) at Western and partner institutes. His active projects investigate meteorites, crustal cross-sections, kimberlite xenoliths, sedimentary basins and impact structures in the Americas, Africa and Europe. His ZAPLab team is advancing our knowledge of the timing and nature of processes that form and modify planetary crusts and ore deposits while advancing the growing sub-discipline of accessory mineral science.
