High-throughput assaying of heterogeneous bacterial populations at the single cell level using drop-based microfluidics

Date/Time: Monday, December 2 4:10 p.m - 5:00 p.m.
Location: Barnard Hall 108
Speaker:Connie B. Chang

Abstract: Conventional methods in microbiology can be limited by long assay execution and analysis times, large reagent volumes, and high single-use supply costs. These limitations can be overcome using drop-based microfluidics in which picoliter-sized, water-in-oil emulsions serve as independent microreactors, allowing for the compartmentalization of microbes and high-throughput assaying at the single cell level. Here, drop-based microfluidics is used to interrogate the physiological heterogeneity of P. aeruginosa cells in a microbial population using a technique we name DropSOAC (Drop Stabilization On A Chip). The DropSOAC method stabilizes the position and volume of monodisperse water-in-oil drops with diameters <20 mm within a monolayer array on a microfluidic chip for 24 h. The stability of drops is maintained by soaking the device in a reservoir containing both water and oil in thermodynamic equilibrium. This ensures that phase equilibrium of the drop emulsion fluids within the porous PDMS material structure is maintained during drop incubation and imaging. Continuing this work, we aim to study the rapid emergence of antibiotic resistance now observed in common bacterial strains to find effective treatments for persistent bacterial infections. This will be performed using a microfluidic chip that is capable of encapsulating in parallel, 96 barcoded assay samples in drops using fluorescent particles. Using a custom-built microscope that can read fluorescence from drops at rates of thousands per second, we demonstrate sorting for a particular barcode combination from our droplet library. The results presented here show the potential of drop-based microfluidics for high-throughput assaying of heterogeneous populations of microbes at the single cell level.

Gromov-Wasserstein distances and distributional invariants of datasets

Date/Time: Monday, November 25 4:10 p.m - 5:00 p.m.
Location: Barnard Hall 108
Speaker: Facundo Mémoli

Abstract: The Gromov-Wasserstein (GW) distance is a generalization of the standard Wasserstein or Earth Mover's distance between two probability measures on a given ambient metric space. The GW distance assumes that these two probability measures might live on different ambient spaces and therefore implements an actual comparison of pairs of metric measure spaces. Metric-measure spaces are triples (X,dX,muX) where (X,dX) is a metric space and muX is a Borel probability measure over X and serve as a model for datasets.

In practical applications such as shape matching, this distance is estimated either directly via gradient based optimization approaches, or through the computation of lower bounds which arise from distributional invariants of metric-measure spaces. One particular such invariant is the so called 'global distance distribution' of pairwise distances.

This talk will overview the construction of the GW distance, the stability of distribution based invariants, and will discuss some results regarding the injectivity of the global distribution of distances for smooth planar curves.

Title: Parameter Inference and Parameter Advising in Computational Biology

Date/Time: Monday, April 15 4:10 p.m - 5:00 p.m.
Location: Barnard 108
Speaker: John Kececioglu

Abstract: Many scenarios in computational biology involve an optimization model that is solved to find the best reconstruction of an unobserved phenomenon, such as when assembling a genome sequence, inferring an evolutionary tree, predicting the folded state of a protein or RNA molecule, or computing a multiple sequence alignment. Key to such models is the objective function being optimized, which often has many free parameters that must be tuned. Setting these parameter values is crucial, as they can radically affect the accuracy of the reconstructions output by tools that optimize such models. We discuss two forms of the problem of automatically finding good parameter settings for such models: (1) parameter inference, which finds the best default parameter setting that yields reconstructions of highest average accuracy over a collection of benchmark training examples; and (2) parameter advising, which selects a good parameter choice from a collection of possible settings to yield a reconstruction of highest estimated accuracy for a user's specific input data. We present general and efficient algorithms for parameter inference and parameter advising, and report concrete results for the context of protein multiple sequence alignment. This is joint work with Dan DeBlasio and Eagu Kim.

Title: MOOSE: Multiphyiscs Object Oriented Simulation Environment Creating Extensible, Composable Algorithms and Software

Date/Time: Monday, April 1 4:10 p.m - 5:00 p.m.
Location: Barnard 108
Speaker: Andrew Slaughter

Abstract: Multiphysics, by its very nature, is best achieved through collaboration. Researchers usually have deep knowledge within a single discipline, thus attempting to tie multiple disciplines together within a single simulation requires reaching out to peers in a collaborative effort. To the contrary, researchers regularly maintain unique code bases and adhere to a variety of software development workflows making sharing code nearly impossible. The open-source Multiphysics Object Oriented Simulation Environment (MOOSE; mooseframework.org) is a platform designed by Idaho National Laboratory (INL) scientists for creating collaborative software, and more importantly creating cross-discipline, finite-element, multiphysics simulation tools. This is accomplished by allowing scientists to work independently within their specializations and then smoothly connect their efforts together to achieve high-fidelity, scalable, Multiphysics simulations. MOOSE has many features for enabling multiphysics collaboration including a unique object structure, execution of multiple simultaneous MOOSE-based calculations with data transfers, and a collaboratively created set of physics "modules". In addition, it includes tools for testing, visualization, and documentation. These aspects have helped define a workflow for scientific software at INL and beyond that has accelerated a multitude of multiphysics endeavors such as multiscale material science, full-core nuclear reactor simulation, and geophysical simulation. An overview of the design of MOOSE, the associated workflow, how it has accelerated collaboration, and associated examples will be presented with the goal of expanding our long list of collaborators to Montana State University.

Biosketch: Andrew began his academic studies focusing on structural engineering while studying at Michigan Technological University (B.S.) and Washington State University (M.S.). He shifted focus for a Ph.D. at Montana State University where he studied Applied Engineering Mechanics and researched snow and avalanche physics.

In 2013, Andrew joined Idaho National Laboratory (INL) and the Multiphysics Object Oriented Simulation Environment (MOOSE; mooseframework.org) team, adding to the wide spectrum of research expertise. Since joining INL, he has worked as a developer and has focused on simulation output, control structure, stochastic analysis, as well as the level set and shallow water physics modules. He also has contributed significantly to the MOOSE-based seismic analysis tool MASTODON and a variety of other projects including enhancing software quality practices and visualization.


Title: What We Have Learned About Using Software Engineering Practices in Research Software

Date/Time: Monday, March 25 4:10 p.m - 5:00 p.m.
Location: Barnard 108
Speaker: Jeffrey Carver

Abstract: The increase in the importance of Research Software (i.e. software developed to support research) motivates the need to identify and understand which software engineering (SE) practices are appropriate. Because of the uniqueness of the research software domain, existing SE tools and techniques developed for the business/IT community are often not efficient or effective. Appropriate SE solutions must account for the salient characteristics of the research software development environment. To identify these solutions, members of the SE community must interact with members of the research software community. This presentation will discuss the findings from a series of case studies of research software projects, an ongoing workshop series, and the results of interactions between my research group and research software projects.

Speaker: Laura Stanley

Abstract: Research demonstrates that ten percent of the population becomes addicted to opioids from exposure to narcotics in the operative setting. The abuse and addiction from these drugs have now placed the US in the center of an “opioid epidemic”. As a result, a variety of programs and interventions are being explored to treat the pain and anxiety associated with surgery and the addiction resulting from opioid use disorder while minimizing or eliminating the need for pharmaceutical intervention. One such “alternative” treatment for pain, anxiety, and addiction involves the use of immersive technologies (e.g. virtual, augmented, and mixed reality) as a primary or adjunct technique. Dr. Stanley will present her team’s on-going clinical research trials at Prisma Health involving the development and efficacy of immersive technologies to address pain and anxiety in operative and cancer treatment environments, and addiction for those suffering from opioid use disorder.  She will discuss her cyber-human systems approach to addressing mental health challenges utilizing knowledge from a variety of computing domains such as affective computing, human computer interaction, and computational psychophysiology.

Title: Securing Our Most Personal Devices and Networks in the Internet of Things

Date/Time: Friday, February 1 4:10 p.m - 5:00 p.m.
Location: Barnard Hall 108
Speaker: Travis Peters

Abstract: In the Internet of Things (IoT) , everyday objects are equipped with the ability to compute and communicate. These smart things  have invaded the lives of everyday people, entering into our homes, our oces, our cars, and are even being constantly carried or worn on our bodies; they have intimate and daily access to our most personal data as well as all of the other devices that we own and encounter throughout our day. Without a doubt, the devices and networks of today are more personal than ever. It should, therefore, come as no surprise that our personal devices and data are frequent targets of ever-present threats. Securing these devices and networks, however, is challenging.

In this talk, I present my work on developing designs, techniques, and tools to harden software and systems in a way that aims to prevent  and detect  prominent threats to our most personal devices and networks. First, I present our Trusted I/O solution for protecting sensitive user data transferred between wirelessly connected (Bluetooth) devices. Specically, I will discuss our BASTION-SGX project, which shows how in-transit data can be protected from privileged threats (e.g., compromised OS) on commodity systems. I present insights into the Bluetooth architecture, Intel's Software Guard Extensions (SGX), and how a Trusted I/O solution can be engineered on commodity devices equipped with SGX. Second, I discuss how we can both improve the utility and security of microcontroller-based devices. Specically, I will discuss our Amulet project and how we successfully built a wearable health hub that can run multiple health applications, provide strong security properties, and operate on a single charge for weeks or even months at a time. I will present the mobile health scenario that Amulet addresses, dig into the software and hardware architectures of the Amulet platform, and present some of the interesting results that Amulet achieves. This talk will conclude with a discussion on some of my planned future work towards improving the state of security within personal devices and networks, as well as a glimpse into some of my ongoing work on the active detection of threats within this context.

Title: Data-oriented and Trustworthy IoT Services for a Cyber-Physical World

Date/Time: Friday, January 25 4:10 p.m - 5:00 p.m.
Location: Barnard Hall 108
Speaker: Ruozhou Yu

Abstract: The Internet-of-Things (IoT) has the potential to revolutionize our daily lives. Yet, we are facing major challenges in deploying IoT to solve real-world problems. On one hand, the huge volume of data generated by IoT devices must be transmissible and comprehensible by our existing infrastructures. On the other hand, the complexity, heterogeneity and scale of IoT-based systems have led to new security risks in our digital or even physical lives. Resolving these challenges require sophisticated computing and analytical mechanisms in data science, machine learning, cybersecurity, and/or social sciences, but the applicability of these mechanisms in IoT is largely restricted by the limited computing, networking and energy resources in many real-world IoT scenarios.

In this talk, I will focus on my efforts in addressing the above challenges in resource-constrained IoT. To solve the big data challenge, I design algorithmic solutions for cross-layer networking and computing design, providing guaranteed performance for IoT services and applications, while increasing resource utilization, reducing congestion, and improving system robustness. To solve the security challenge, I propose using the blockchain as a basic building block for establishing a secure IoT platform, and introduce how it can be extended to enable a global scale on-demand IoT marketplace. While the proposed solutions can largely address the above challenges in IoT, many of them also have applications and extensions beyond this specific context.

Title: Phylofactorization: evolution + a graph-partitioning algorithm = machine learning + human understanding of biological data

Date/Time: Monday, January 14 4:10 p.m - 5:00 p.m.
Location: Barnard Hall 108
Speaker: Alex Washburne

Abstract:  Biologists are obtaining massive datasets of hundreds of thousands of species and their abundances, traits, and other features. From microbes living in our gut to birds found in tropical rainforests, there is a universal need to make sense of which organisms are sensitive to climate change, which are associated with disease, and more. The theory of evolution defines a history of organisms in the form of a tree going back to common ancestors over 3.6 billion years ago. In this talk, I will discuss how that tree - an acyclic graph - can be used to define a graph-partitioning algorithm for interpretable dimensionality reduction of biological data. So far, this algorithm has yielded insights on the evolution of mammals over the past 65 million years, the microbes who thrive in the intestines of patients with Crohn's Disease or Inflammatory Bowel Disease, the microbes differentiating our intestinal communities over America, how mammalian viruses are more or less likely to jump from animals to people, how mammalian reservoirs are more or less likely to have pathogens capable of infecting people, and more. This algorithm connecting the theory of evolution to reduced rank regression, artificial neural networks, and virtually every tool used for data analysis is accelerating the machine learning and human understanding of biological systems.

Biosketch: Dr. Alex Washburne received undergraduate degrees in Biology and Applied Mathematics from the University of New Mexico. He received his Ph.D. from Princeton University in Quantitative and Computational Biology, where he discovered a mathematical commonality between the dynamics of microbes in humans, trees in tropical rainforests, stocks in the stock market and other entities in competitive systems. The underlying symmetry of competition was used to create statistical tests of competitive intensity which landed Dr. Washburne a job in a hedge fund. While working at a hedge fund, he did a post-doc at Duke University with Diana Nemergut who passed away within 3 months of the start date but secured funding for Alex to continue his research for two years. In this time, he conceived phylofactorization and began work on statistical models of pathogen spillover. He is now a research scientist at MSU working with Raina Plowright on Defense Advanced Research Projects Agency (DARPA) funded projects predicting and preempting the spillover of pathogens like Ebola from wildlife to people. He is the founder and head of Selva Analytics LLC, a consulting firm developing statistical tools to facilitate the accumulation of domain expertise for clients in sectors ranging from biotech and energy to finance and resource management.
