CSE Doctoral Student Seminar: Shali Jiang and Cynthia Mahttps://engineering.wustl.edu/Events/Pages/CSE-Doctoral-Student-Seminar-Shali-Jiang-and-Cynthia-Ma.aspx1440CSE Doctoral Student Seminar: Shali Jiang and Cynthia Ma2018-02-23T06:00:00Z12:30 p.m.2 p.m.Lopata Hall, Room 101<p><strong>"Efficient Nonmyopic Batch Active Search"<br/></strong></p><p><strong>​Shali Jiang</strong><br/>Adviser: Roman Garnett</p><p>Active search is a learning paradigm for actively identifying as many members of a given class as possible. Important applications include drug discovery, fraud detection, and product recommendation. All existing work focuses on sequential policies, i.e., selecting one point to query at a time. However, in many real applications, it is possible to evaluate multiple points simultaneously. In this paper we investigate batch active search, the first such study we know of in the literature. We first derive the Bayesian optimal policy for batch active search, and prove a lower bound on the performance gap between sequential and batch optimal policies. Then we propose novel batch policies inspired by state-of-the-art sequential policies, and develop an aggressive pruning technique that can further speed up the computation by up-to nearly 50 times. We conduct thorough experiments on three application domains: a citation network, material science, and drug discovery, testing all proposed policies (14 total) for a wide range of batch sizes. Results show that the empirical gap matches our theoretical bound; nonmyopic policies usually beat myopic ones significantly; we also find diversity to be an important consideration for batch policy design.<br/></p><p> <strong>"Modeling Gene Networks using TFA Inference"</strong></p><p><strong>Cynthia Ma</strong><br/>Adviser: Michael Brent<br/></p><p>A single cell, whether yeast or human, has no consciousness, but can respond to changes in its environment such as by building tools to harvest encountered nutrients while stopping the production of tools for nutrients no longer available. This is accomplished through complex networks of signals, looping in and out from genes in the cell’s DNA that encodes instructions for building said tools, as well as for building the signal carriers. To model these networks, it makes sense to include the activity of the signal carriers, particularly transcription factors (TFs) that directly activate or repress the copying of instructions from genes, but current technology is unable to efficiently measure these. As such, computational inference of transcription factor activity (TFA) from cell state information that can be efficiently measured is an ongoing problem. This talk will briefly review previous work, the common obstacles, and the current trajectory of TFA inference.<br/></p>

The interdisciplinary nature of system security further presents the researcher a vast space to explore such opportunities. In this talk, I will share our experience in finding and understanding security weaknesses on the technology frontier, demonstrating how big questions can be asked to help discover subtle but fundamental security problems inside modern computing systems, and how such findings can reshape system security designs, bringing forth new techniques, new research directions.  More specifically, using mobile and IoT as examples, I will show that discovery and analysis of their surprising side channel weaknesses (which can be exploited by even the apps without permissions to expose one's identity, locations, health information, etc.) questions the "security by construction" designs of these systems, identifying what need to be addressed to better protect them.  Further to be presented is the preliminary effort to automate such a discovery process, by leveraging the knowledge automatically recovered from documents to guide detection of security-critical vulnerabilities.  Finally, I will highlight the key insights of system security research and discuss the directions that might impact the development of new security technologies in the years to come.</p><p><strong>Biography</strong></p><p>Dr. XiaoFeng Wang is a James H. Rudy Professor of Computing at Indiana University, Co-director of IU's Center for Security and Privacy in Informatics, Computing and Engineering, and the Vice Chair of the ACM SIGSAC (special interest group on security, audit and control).  He is also a PC Co-Chair of the 2018 ACM Conference on Computer and Communications Security (CCS).  Dr. Wang received his Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University.  He is considered to be one of the most prominent system security researchers, among the most productive authors at leading security venues (#5 among over 6,000 authors in the past 18 years according to online statistics: http://s3.eurecom.fr/~balzarot/notes/top4/).  Dr. Wang is known for his high-impact research on security analysis of real-world systems and biomedical data privacy. Particularly the projects he led on payment and single-sign-on API integrations, Android and iOS security and IoT protection have changed the way the industry built these systems.  Also he is a pioneer researcher on human genome privacy and a co-founder of the iDASH Genome Privacy Competition that bridges the frontline security and cryptography research and the real-world demands for biomedical data sharing and computing protection. More recently, he is actively working on Data-Centric Intelligent Security, Cybercrimes, Hardware-support Protection and IoT Security. For his work, Dr. Wang has received numerous awards, including the Award for Outstanding Research in Privacy Enhancing Technologies (the PET Award) and the Best Practical Paper Award at the 32nd IEEE Symposium on Security and Privacy.  His research has been extensively reported by the public media, including CNN, MSNBC, Forbes, Slashdot, Nature News, etc.<br/></p>

While leading to improved services, such transformation also introduces new security challenges. To address these challenges, in contrast to existing defense mechanisms that are mostly ad hoc and reactive, my research aims at developing proactive defense approaches that can systematically discover, analyze, and mitigate new security problems in smart, connected systems.<br/></p><p style="text-align: justify;"> In this talk, I will focus on my research efforts in securing two most basic components in any smart, connected system: network stack and smart control. For network stack security, I will describe our discovery of a new attack vector (US-CERT alert TA16-144A) brought by the recent expansion in DNS and our subsequent systematic analysis at both network and software levels for remediation purposes. For smart control security, I will describe my most recent work that performed the first security analysis of the next-generation Connected Vehicle (CV) based traffic signal control, which discovers new vulnerabilities at the traffic signal control algorithm level. I will conclude by discussing my future research plans in securing existing and future smart, connected systems, especially those in critical domains such as transportation and automobile.</p><p><strong>Biography</strong></p><p>Qi Alfred Chen is a PhD candidate in the EECS department at University of Michigan advised by Professor Z. Morley Mao. His research interest is network and systems security, and the major theme of his research is to address security challenges through systematic problem analysis and mitigation.

I will present a framework for modeling privacy risk from an adversarial perspective, and a game theoretic approach for balancing the utility from shared data with privacy risk. Finally, I will describe an approach for reasoning about privacy risk associated with sanitizing clinical notes using machine learning techniques, and present a novel algorithm for this task which has provable guarantees about privacy risk (given our threat model) and preserves most of the original content.</p><p><strong>Biography</strong></p><p>Yevgeniy Vorobeychik is an Assistant Professor of Computer Science and Biomedical Informatics at Vanderbilt University.
