lessAbstract: As urban populations continue to increase in the U.S. and globally, there is growing concern about the impact of urban environmental determinants on population health, ranging from traditional pollutants to emergent issues such as natural disasters. This talk will focus on modern exposure science approaches to characterize exposures to air pollution, extreme weather, and green space as well as to incorporate them in health research to understand potential biological mechanisms. These approaches include engineering methods, advanced statistical models, GIS, and machine learning methods. The approaches highlighted throughout the talk are applicable to environmental engineering, transportation, civil engineering, epidemiology, risk assessment and public health.

Dr. Zhang received a PhD degree in Environmental Health and a MA degree in Statistics at the University of Michigan, and a MS degree and a BS degree in Environmental Engineering from Tsinghua and Southeast University in China, respectively. Dr. Zhang’s research interest focuses on characterizing climate-related exposures, reducing the human health effects associated with disasters, and exploring the role of social and environmental stressors (air pollution, natural environment, built environment, and green space) in relation to chronic diseases. Dr. Zhang serves as the Secretary of the International Society of Exposure Science (ISES). He is also an Associate Editor for Science of the Total Environment and the Journal of Exposure Science and Environmental Epidemiology.

lessAbstract: The ability of eukaryotic cells to fit nearly 2 meters of DNA into a single micron-scale nucleus, as well as selectively access the right genes at the right time, is a physical challenge that remains a key biological question. How DNA is folded in 3D can influence which genes are easy to turn on or off, particularly during stress. Emerging research in mammalian cells has shown that chromatin, the DNA and its associated histone proteins, are not arranged as a fixed, rigid hierarchy. Instead, chromatin has been found to form, dynamic, heterogenous “neighborhoods”: nanoscale “packing domains” characterized by dense interior cores and more open outer regions, held in place by different factors, such as post-translational modifications of the histone proteins. These local 3D environments help shape gene activity and could contribute to cellular
“memory” of past conditions. This paradigm shift in chromatin 3D organization may be critically important for our understanding in the resilience of ecologically important species, as environments change due to anthropogenic activities. Here, we ask whether similar 3D packing principles occur in reef-building corals, sessile organisms which must respond quickly to environmental change, such as marine heat stress. Although the field of coral epigenetics is rapidly growing, the potential role of 3D genome organization in regulating gene expression remains largely unexplored. We adapt ChromSTEM, a high-resolution electron microscopy approach, to visualize and quantify DNA packing in coral cells at nanometer resolution and compare these patterns to those reported in human cells. This work is a first step toward connecting 3D genome structure with gene regulation and stress responses in a non-model, ecologically important organism.Bio: Shanna Davidson is a postdoctoral scholar in the Marcelino lab in Civil and Environmental Engineering at Northwestern University. Prior to joining Northwestern, she earned her PhD in Chemical and Petroleum Engineering from the University of Pittsburgh. Her current research bridges physical genomics and environmental science by investigating how the three-dimensional organization of chromatin regulates cellular responses to environmental change. Utilizing a suite of nanoscale imaging techniques and molecular approaches, she studies genome architecture in corals to understand how these ecologically critical organisms respond to ocean warming.

lessAbstract: Many natural hazards have been well known and qualitatively understood for decades, but still lack accurate measures of how damaging future events will be. For example, it still remains a question as to how quickly the great ice sheets in Antarctica and Greenland will respond to climate change to cause sea level rise, and whether early warning for debris flows can be successfully implemented. For both of these examples, a key need is to better understand the mechanics of the underlying geophysical processes. In this talk, I introduce the basic mechanical principles related to ice sheet flow and debris flow damage, and explain how application of these simple principles results in an enhanced ability to quantify certain aspects of these hazards.
Biosketch: Victor has a broad range of geophysical interests from understanding earthquake mechanics and hazards to predicting the future of melting and collapse of glaciers and ice sheets. He enjoys simplifying the complexity of geophysical phenomena to make them tractable to comprehend and model mechanistically. Victor joined the Department of Earth, Environmental and Planetary Sciences at Brown University in 2019, where he is a professor of geophysics. He was previously a professor of geophysics at Caltech for eight years, and a postdoc at the US Geological Survey for two years. He earned his B.S. in geophysics at Caltech and his Ph.D. at Harvard University.

lessAbstract: Anaerobic biotechnology is used to treat municipal wastewater sludge and many industrial wastewaters. In the process, microbes degrade pollutants and convert them to biogas containing methane. The methane gas can be used for heat and energy generation. Therefore, the process includes both wastewater management and renewable energy generation. Often, the Anaerobic Digestion Model #1 (ADM1) is employed to help design and understand anaerobic treatment systems. Fundamental model inputs include maximum Monod substrate utilization rate constants (km). Unfortunately, the kinetic constant values can actually vary greatly, based, in part, on the exact microbial community present in the engineered process (i.e., the identity of microbes and the numbers of each). Unfortunately, there are no standard, simple methods to measure the kinetic values since determining the concentration of active microbes in a given trophic group. is difficult. Having a method to determine active trophic group microbial concentrations as well as kinetic constant values would help us understand the process and design/model anaerobic bioprocesses. In this talk, a novel respirometer method to determine Monod kinetic constant and active biomass concentrations will be presented. Using the technique, the maximum specific acetate utilization rates for biomass from more than 20 full-scale anaerobic bioprocesses was found to vary greatly. Surprisingly, some biomass samples exhibited extremely high acetate utilization rates (>40 g COD/g CODx-d), whereas flocculant municipal biomass rates were similar to the ADM1 default value of 8 g COD/g CODx-d. Rate data were compared to genomic data and results supported the hypothesis that acetate oxidation (i.e., the conversion of acetate to H2 and CO2) is more prevalent in well-functioning digesters than assumed. Granular biomass was especially rich in acetate oxidizing potential, and this may also be supported by significant interspecies electron transfer in granules. The important link between microbial community composition and bioprocess function will be highlighted. Just as the human gut microbiome varies from person to person and can influence health, anaerobic digester microbiomes can vary and influence process function.
