Talk Title: Understanding WebAssembly via Program Transformation
Series: CS Colloquium
Abstract: WebAssembly is the newest language for the web, aiming to enable high-performance applications and provide languages such as C/C++ a compilation target so that they can be run on the web. WebAssembly defines a portable binary instruction set, as well as a corresponding textual assembly format. However, WebAssembly's syntax is difficult to interpret for human readers because of the stack machine-based implementation. As a result, distributed third-party WebAssembly modules need to be implicitly trusted by developers as verifying the functionality requires significant effort.
In this talk, I will describe my work towards building analysis tools for developers to understand WebAssembly programs. The first section of the talk will focus on identifying limitations of current analysis tools: I will introduce a code obfuscation technique for obfuscating JavaScript malware by translating parts of the computation into WebAssembly. By pinpointing limitations of current malware detectors, my work motivates future efforts on detecting multi-language malware on the web that uses WebAssembly. The second section of the talk will focus on a set of abstraction rules for WebAssembly instructions, which can be used to lift WebAssembly to a high-level representation that abstracts the underlying semantics of the code. I have applied the abstraction rules in detecting WebAssembly-based cryptomining malware. My detection relies on program semantics unique to cryptomining, which is resilient to variants.

Talk Title: Manifold Learning for High Dimensional Uncertainty Quantification
Abstract:
Uncertainty Quantification (UQ), the systematic and rigorous accounting of uncertainties, has become widely accepted as an essential component of any proper scientific investigation -“ whether computational, experimental, or otherwise. In computational science and engineering, as well as in experimental investigations, we often encounter problems that are parameterized by very high-dimensional quantities and/or result in very high-dimensional quantities of interest. Thanks to the curse of dimensionality, the challenge of solving these problems grows exponentially with the problem dimensions. This explosive growth in complexity has been widely known for decades and may never be truly resolved. However, all hope is not lost. In this presentation, we offer some strategies for addressing high dimensional UQ problems whose uncertainties can be expressed in lower-dimensional latent spaces or on manifolds whose geometry is not necessarily Euclidean. We begin by introducing some concepts in Reimannian geometry and nonlinear dimension reduction, specifically reviewing Grassmann manifolds and diffusion maps, and show how UQ problems with high dimensional solutions can be solved by projecting solution snapshots onto the Grassmann manifold, performing diffusion maps on the manifold, and constructing surrogate models on the resulting low-dimensional space using standard machine learning methods such as Gaussian process regression, polynomial chaos expansions (PCE), or deep neural networks. Next, we consider problems with very high dimensional inputs and present a survey of 13 different unsupervised learning methods for dimension reduction, which are used to identify low-dimensional latent spaces on which PCE surrogates are constructed. Some takeaways from this general approach, termed manifold-PCE, are presented. Finally, we bring the two components together to propose a general framework for UQ in high dimensions that is widely applicable and very flexible.
Biography: Michael D. Shields is an Associate Professor in the Dept. of Civil & Systems Engineering at Johns Hopkins University and holds a secondary appointment in the Dept. of Materials Science and Engineering. Prof. Shields conducts methodological research in uncertainty quantification and stochastic simulation for problems in mechanics, materials science, and physics with applications ranging from multi-scale material modeling to assessing the reliability and safety of large-scale structures. He received his Ph.D. in Civil Engineering and Engineering Mechanics from Columbia University in 2010, after which he was employed as a Research Engineer in applied computational mechanics at Weidlinger Associates, Inc. He joined the faculty at Johns Hopkins in 2013. For his work in UQ, Prof. Shields has been awarded the ONR Young Investigator Award, the NSF CAREER Award, the DOE Early Career Award, and the Johns Hopkins University Catalyst Award. Prof. Shields and his group also develop the open-source UQpy (Uncertainty Quantification with Python) software, which is a general toolbox for UQ in computational, mathematical, and physical systems.

McKinsey & Company Info Session, hosted by Affinity Networks (Virtual)
Thu, Mar 31, 2022 @ 07:00 PM - 08:00 PM
Viterbi School of Engineering Career Connections
Conferences, Lectures, & Seminars
Abstract: Our global All In, Diversity & Inclusion initiatives engage colleagues around the world to develop and share innovative ways of working that advance inclusivity. To ensure diversity in gender, ethnicity, background, education, orientation, etc., we constantly look for new ways to reach people who might otherwise not be considering consulting as a career option.
For this session, we will be talking about our global culture of inclusion and our Affinity Networks, and also sharing a few details about the application process.
