Bacterial motility and growth play central roles in agriculture, the environment, and medicine. While
bacterial behavior is typically studied in bulk liquid or on flat surfaces, many bacterial habitats—e.g.,
soils, sediments, and biological gels/tissues—are complex and crowded spaces. In this talk, I will
describe my group’s work using tools from soft matter engineering to address this gap in knowledge. In
particular, using studies of E. coli in transparent 3D porous media, we demonstrate how confinement in
a crowded medium fundamentally alters bacterial behavior. In particular, we show how the paradigm of
run-and-tumble motility is dramatically altered by pore-scale confinement, both for cells performing
undirected motion and those performing chemotaxis, directed motion in response to a chemical
stimulus. Our porous media also enable precisely structured multi-cellular communities to be 3D
printed. Using this capability, we show how spatial variations in the ability of cells to perform
chemotaxis enable populations to autonomously stabilize large-scale perturbations in their overall
morphology. Finally, we show how when the pores are small enough to prevent cells from swimming
through the pore space, expansion of a community via cellular growth and division gives rise to distinct,
highly-complex, large-scale community morphologies. Together, our work thus reveals new principles to
predict and control the behavior of bacteria, and active matter in general, in complex and crowded

The classical paradigm of tissue engineering involves an integrated use of human stem cells, biomaterials (providing a specialized template for tissue formation) and bioreactors (providing environmental control, dynamic sequences of molecular and physical signals and insights into the structure and function of the forming tissues). This approach results in an increasingly successful representation of tissue development, regeneration and disease. Bioengineered human tissues are now being tailored to the patient and the condition being studied or treated. A reverse paradigm is emerging in recent years, with the emergence of “organs on a chip” platforms for modeling integrated human physiology, using micro-tissues derived from human iPS cells and linked by vascular perfusion. The common objectives are to recapitulate the cellular niches that can modulate cell behavior towards generating functional equivalents of native tissues. To illustrate the state of the art in the field and reflect on the current challenges and opportunities, this talk will discuss bioengineering of clinically relevant tissues and the use of “organs on a chip” platforms for patient-specific studies of human patho/physiology.
Gordana Vunjak-Novakovic is University Professor, the highest academic rank at Columbia University and the first engineer at Columbia to receive this distinction. The focus of her lab is on engineering functional human tissues for use in regenerative medicine and patient-specific “organs-on-a-chip” for studies of human physiology in health and disease. She is well published and highly cited (h=132), has mentored over 150 trainees, and launched four biotech companies form her lab.
She is serving on the Council of the NIBIB, the HHMI Scientific Review Board, and on numerous editorial and scientific advisory boards. She was inducted into the Women in Technology International Hall of Fame, received the Clemson Award of the Biomaterials Society, Pritzker Award of the Biomedical Engineering Society, Shu Chien Award of the AIChE, Pierre Galletti award of the AIMBE, and was elected Fellow of several professional societies. She was decorated by the Order of Karadjordje Star – Serbia’s highest honor, and elected to the Academia Europaea, Serbian Academy of Arts and Sciences, the National Academy of Engineering, National Academy of Medicine, National Academy of Inventors, the American Academy of Arts and Sciences and the International Academy for Medical and Biological Engineering.

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.
Redesigning Drug Design by Dr. John Chodera
Wednesday, December 8th @ 10:00AM
Zoom Link: https://utoronto.zoom.us/j/87130346324
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

Air quality, odour, health and equity: Leveraging interdisciplinary approaches to understand the impacts of cannabis cultivation in Metro Vancouver
In 2018, Canada became the only G7 nation to legalize cannabis for non-medical (recreational or non-prescribed uses) and medical use at the federal level. To date, there are over 500 facilities with licenses to cultivate cannabis. Of these, almost 25% are located in British Columbia, with some of the largest cultivation greenhouses being located or developed in the Metro Vancouver region.
As the number and size of cannabis cultivation facilities (CCFs) have grown, so have odour-related complaints; a report from March 2019 listed 326 complaints in Metro Vancouver over a 12-month period. The odours associated with CCFs are caused by emissions of volatile organic compounds (VOCs), which can also increase formation of health-damaging pollutants such as ground-level ozone (O3) and particulate matter (PM). As such, air quality regulators have begun exploring options to curb these emissions. In this talk, I will highlight ongoing work in the Metro Vancouver region to understand CCF emissions from an interdisciplinary lens. This includes the development and deployment of a citizen science web application for reporting CCF odours and observed health effects (https://www.smell-vancouver.ca), modelling of odourous emissions and their dispersion, and plans for real-world ambient sampling of emissions from CCFs using mobile monitoring. The talk will also provide a high-level summary of identified knowledge gaps in our understanding of the air quality impacts of CCF facilities from the occupational to community scale.

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.
