Previous Seminars (2017-18) 

Dr. Peter Pirkelbauer March 19th, 2:00 p.m., UTC SimCenter Auditorium*

Topic: "Petal: Rejuvenation of MPI Applications / Ariadne: Static Analysis Meets Model Checking"

Dr. Peter Pirkelbauer, Assistant Professor, Department of Computer Science at the University of Alabama at Birmingham

In the first part, I will present Petal, a prototype tool that uses compiler-analysis to automate code transformations to hide communication costs behind computation by replacing blocking MPI functions with corresponding nonblocking and persistent collective operations while maintaining a legacy applications’ correctness. Petal transforms point-to-point and collective MPI operations to their nonblocking and persistent counterparts. Depending on system scale and problem size, the transformations yield a speedup of up to a factor of two.

A second part of the talk will revisit model checking as a means to verify the correctness of concurrent software. While model checking is a powerful tool, scalability remains a challenging problem due to the combinatorial explosion of the state space. To circumvent that, I will present a tool that translates a static analyzer’s reports of suspected race conditions to instrumentation that can be exploited by a model checker (Java Pathfinder). I will provide details of the instrumentation algorithm and present experimental results.

Dr. Mark YampolskiyFebruary 22nd, 2:00 p.m., UTC SimCenter Auditorium*

Topic: "Security of Additive Manufacturing: Threats and Research Opportunities"

Mark Yampolskiy, Assistant Professor,  School of Computing University of South Alabama

Industry 4.0 envisions a fully automated Factory of the Future, in which computerized and inter-networked manufacturing equipment performs all tasks. Additive Manufacturing (AM), a.k.a. 3D printing, is one of the crown jewels of this vision. AM is a rapidly growing multibillion-dollar industry that is increasingly used to manufacture functional parts, including components of safety critical systems in the aerospace, automotive, and other industries. However, reliance on the IT infrastructure and the high degree of computerization of the manufacturing machines make AM susceptible to a variety of cyber and cyber-physical attacks, particularly sabotage.

AM Security is a fairly new and highly inter-disciplinary field of research that aims to address the novel threats emerging for this manufacturing technology. This talk will provide an introduction to the field. Focusing on AM sabotage, one of the identified threat categories, Dr. Mark Yampolskiy will cover research performed by his own and other research teams. The talk will first present an overview of attacks shown in the literature, distinguishing between Attack Vectors, Compromised Elements, Manipulations, and Effects. Then newly proposed approaches will be outlined that aim to harden AM against threats. Selected attacks and defense measures proposed by Dr. Yampolskiy’s research team will be discussed in more detail.

Mark Yampolskiy received Ph.D. in Computer Science from Ludwig-Maximilians University of Munich, Germany. He currently holds an Assistant Professor position at the University of South Alabama.

Since his post-doctoral appointment at Vanderbilt University 2012-2013, Mark Yampolskiy is performing research on Security of Cyber-Physical Systems (CPS). Mark Yampolskiy was among the researchers who pioneered Security of Additive Manufacturing (AM, a.k.a. 3D Printing) around 2014. AM Security remains his major research interest ever since. His work is predominantly associated with two threat categories, sabotage of 3D-printed functional parts and theft of intellectual property. He has numerous publications in the field, ranging from attacks on/with AM up to novel approaches for the detection of such attacks.

In order to address the challenges of this highly interdisciplinary research field, Mark Yampolskiy actively collaborates with experts from different disciplines. His major collaboration partners are affiliated with Lawrence Livermore National Laboratory (LLNL), Auburn University (AU), Ben Gurion University of the Negev (BGU), Israel, and Singapore University of Technology and Design (SUTD), Singapore.

Topic: "Information Security Careers: Pathfinding on the Digital Battlefield"

Shayne Champion, Cyber Security Professional

Information security is now a household term, but this was not always so.  Early adopters of computing in both the personal and professional realms would not have recognized the term nor would they recognize any of the skills such as they existed as a career field.  How and why has that changed?  Is information security important to every member of the modern workforce, or is it just the prevue of aspiring CISOs?

This presentation will discuss the education, career path, and skills one practitioner has undertaken in their path from the early 1990s and the public flourishing of the internet to the modern digital battlefield we all work, study, and live within.  What are the critical steps towards developing yourself as a cyber security professional?  What illusions could impact your ability to get a job in information security?  What are the hard technical and soft skills needed to survive in the modern digital security field?  This discussion will delve into those issues and help you understand what the profession has become in order that you might more quickly navigate your own career progression.  As the Romans were fond of saying, “a fool learns from his own mistakes, while a wise man learns from the mistakes of others.”

With over 20 years of Information Technology (IT) experience, Shayne has built, worked in, lead, and/or managed a wide variety of IT organizations. He has worked to reduce IT risk by implementing robust internal control systems both as a practitioner and as an auditor. When combined with his education, drive for process improvement, demonstrated knowledge and leadership Shayne is a proven asset to the profession.  He currently works at Erlanger Health System as the Director for Information Security and Architecture.

Dr. Vahid AlavianJanuary 19th, 10:00 a.m.UTC SimCenter Auditorium*

Topic: "Energy, Water, and Climate: Challenges and Opportunities in Africa"

Vahid Alavian, Former Water and Hydropower Advisor, Africa Region at The World Bank

Two-thirds of the 930 million population of Sub-Sahara Africa lacks access to energy.  Demand is expected to increase rapidly as a result of accelerated economic growth and urbanization.  While coal is Africa’s largest single source of energy today, it is losing significant ground to hydropower, given the vast endowment of water resources in the continent.  As low-carbon energy cost falls, great opportunities are created for Africa to leap frog into a new era of renewable energy through hydropower, solar, geothermal and wind.  However, the reality of hydrologic variability and climate change has and will continue to have a profound impact on the energy sector, and by extension other development sectors.  In this presentation, Dr. Alavian will address the development challenges and opportunities in Africa at the nexus of water, energy, and climate.  Examples of Africa’s renewable energy production options towards a low-carbon future will be shared against the landscape of climate variability, adaptation, and social and economic development. Moreover, policy, planning, and financing issues related to climate-smart energy and water infrastructure to reduce exposure risks and episodic shocks will be examined.  Possible energy development trajectories through regional cooperation and power trade, together with associated investment needs are proposed.

During a more than 35 year of professional career, Dr. Alavian worked with international financial institutions, governments, donor agencies, private sector, and academia.  He led strategic and technical water and energy-related projects and programs including water resources management, hydropower, dam safety, and climate change in a number of developing countries.  As the Water Advisor at the World Bank, Dr. Alavian provided strategic and technical oversight for the World Bank-financed investments across the globe.  Some of his major work included advising on complex investments at the nexus of water and energy in Africa; leading technical and diplomatic negotiations in a cooperative effort among the Palestinian Authority, Israel, and Jordan as a part of advancing the peace process in the region; and an analytical and advisory study on the potential impact of climate change on the Bank’s water/energy investments and adaptation measures to make these investments climate-smart.  He also led the water-related training and capacity building programs for Bank client countries through the World Bank Institute. Upon retirement from the World Bank in 2011, Dr. Alavian spent 3 years in Haifa, Israel, where he provided strategic and advisory voluntary services at the Bahá’í World Centre.  

Prior to joining the World Bank, he served as the Senior Water Advisor at the United States Agency for International Development (USAID) Global Environment Center, where he helped advance sustainable management of freshwater and coastal resources in developing countries.  Earlier, as a Senior Specialist at the Tennessee Valley Authority, he contributed to some of the agency’s pioneering work on integrating water, energy, and environmental management for sustainable development and growth, including early work on impact of climate change on the TVA system and operation.

Dr. Alavian has a Ph.D. in Civil and Environmental Engineering from the University of Wisconsin, Madison.  He is a Fulbright Scholar and held faculty positions at the University of Illinois, Urbana-Champaign and the University of Zambia, Lusaka, as well as adjunct positions at the University of Tennessee, Knoxville and University of Alabama, Huntsville.  He recently retired and lives in Chattanooga, Tennessee, with his spouse of 38 years, Dr. Barbara Miller.

Dr. Richard BrooksDecember 1st, 10 a.m., UTC SimCenter Auditorium* 

Topic: "Crypto-currency Status and Future Perspectives"

Dr. Richard Brooks, Professor of Electrical and Computer Engineering, Clemson University

With the advent of e-commerce, the development of a virtual on-line currency became inevitable. This speech discusses the current status of crypto-currency systems, their social impact, how their data-structures can be applied to securing other applications, their perceived/actual privacy, and probable evolution.

First we will discuss the precursors of current crypto-currencies and their perceived limitations. This includes credit cards, e-gold, PayPal, and on-line gaming economies (including gold farming). We then describe the innovations that enabled Bitcoin. Special care will be taken to explain the block-chain data-structure and mining; together with how they enable the creation of a stable on-line currency.
We will then discuss the societal impact of Bitcoin. This will include an explanation of some of the most important alt-coin currencies: Ethereum, Monero, zcoin, and Dash. This will include a description of the use of crypto-currencies in the shadow economy. An important aspect of this discussion is the perceived privacy of crypto-currency transactions and how privacy is maintained. We then consider whether or not the approaches currently being used really provide privacy.
The speech ends with a brief conversation considering current trends and the most likely trajectory for crypto-currency technologies.

Dr. Brooks has in the past been PI on research programs funded by the Air Force Office of Scientific Research, National Science Foundation, Department of Energy, National Institute of Standards, Army Research Office, Office of Naval Research and BMW Corporation. These research projects include coordination of combat missions among autonomous combat vehicles (ARO), situation and threat assessment for combat command and control (ONR), detection of protocol tunneling through encrypted channels (AFOSR), security of intellignet building technologies (NIST), experimental analysis of Denial of Service vulnerabilities (NSF), mobile code security (ONR), and security analysis of cellular networks used for vehicle remote diagnostics (BMW).

Dr. Brooks’ current research interests include game theory, strategic reasoning, and information assurance. He was PI of the Mobile Ubiquitous Security Environment (MUSE) Project sponsored by ONR as a Critical Infrastructure Protection University Research Initiative (CIP/URI). It concentrated on creating distributed countermeasures to overcome large-scale network attacks like distributed denial of service and worms. Dr. Brooks was co-PI of a NIST project defining the security standards and protection profiles for the ISO BACNET networked building control systems standard. Dr. Brooks was co-PI of a DARPA ISO program coordinating air campaign command and control and PI of the Reactive Sensor Networks (RSN) Project sponsored by DARPA IXO.

Dr. David AkopianNovember 17th, SimCenter Auditorium*, 10 a.m.

Topic: "Indoor Positioning Advances Exploiting GPS and WLAN Infrastructures"

Dr. David Akopian, Professor in the Electrical and Computer Engineering,  Department of the University of Texas at San Antonio (UTSA), San Antonio, TX

Location-based services (LBS) gained popularity exploiting localization receivers operating according to requirements of U.S. Global Positioning System (GPS) and/or other Global Navigation Satellite Systems (GNSS). Localization of mobile devices is nowadays mandated by U.S. Federal Communications Commission (FCC: E-911) for emergency services and similar mandates are available in other countries as well. Conventional GPS receivers perform well in open sky environments, typically outdoors, while their operation deteriorates or denied in urban canyon and indoor environments, is deteriorated or even denied due to strong signal attenuations and multipath degradations.

Enhanced GPS receiver techniques are proposed for more sensitivity in acquiring satellite signals in such weak-signal conditions. In particular, terrestrial communication channels may assist GPS units in mobile devices by providing GPS navigation data and other information from unobstructed GPS receivers. Receivers are then relieved from the task of demodulating all navigation data from attenuated satellite signals. This concept is referred to as Assisted GPS (A-GPS) and is being supported by many cellular modern communication standards.

While A-GPS enhances operation of GPS receivers, most of the indoor areas are not covered by GPS operation due to signal blockages. An alternative approach exploits WLAN signals for accurate indoor positioning. WLAN signals are nor designed for localization, but their propagation features are peculiar to the receiver locations and signal propagation paths, which is exploited for indoor positioning. 

There are many challenges in both A-GPS and WLAN indoor localization, and an intensive research is underway to bring positioning indoors, so one day it will become a commonly deployed technology similar to outdoor navigation.

The presentation reviews principles of A-GPS and WLAN-based positioning methods, their potential performances and challenges, and related industry trends.

Dr. Ryan BrewerOctober 2nd, 5:30 p.m., Card Auditorium, EMCS 201*

Topic: "For Engineers, Does Career Advancement come from Hard Skills or Soft Skills?"

Dr. Ryan M. Brewer, Associate Professor of Finance, Indiana University

In today’s world, employers demand and value critical thinking, problem solving, and computer capabilities among graduates of technical disciplines. Does this mean focusing on engineering skills development at the expense of social development is the right idea? What skills will get you noticed?, promoted?, or prevent you from being let go during downturns in the business cycle? While mastery of engineering skills is critical to performing well as an engineer or applied scientist, the “soft skills” are those that will get you noticed, retained, and even promoted when they are mastered. Dr. Brewer presents the case for emotional intelligence and other salient soft skills: what are they? Why are they important? How do soft skills relate to career success? And how does one improve their emotional intelligence?

Dr. Ryan M. Brewer is an Associate Professor of Finance with Indiana University (IUPUI/IUPUC). Brewer has taught finance courses and conducted research at IUPUC since 2009. Brewer earned his Ph.D. from Indiana University Bloomington in 2011 on the topic of financial economics: intrinsic valuation.

Why explore deep space? And what technologies will it take to get there? Dr. Paul McConnaughey, Associate Director Technical, at NASA’s Marshall Space Flight Center will discuss the importance of engineering advanced technologies to journey to deep space – to cislunar, the Moon, Mars and beyond. From the evolvable heavy-lift capability of the Space Launch System to cutting edge lander propulsion technology, the journey to deep space will require innovation and the next generation STEM workforce to be successful.

Dr. Paul K. McConnaughey is the associate director, technical, in the Office of the Center Director at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The Marshall Center is one of NASA’s largest field installations, with nearly 6,000 on- and near-site civil service and contractor employees and an annual budget of approximately $2.5 billion.

Named to the position in August 2015, McConnaughey is responsible for ensuring the performance of Marshall’s programs and technical activities, with respect to cost, schedule and mission success.

Originally from the Midwest, he earned his bachelor’s degree from Oregon State University in Corvallis, and his master’s degree and doctorate from Cornell University in Ithaca, New York. After earning his doctorate, McConnaughey spent three years as a professor of soil physics and mathematics at Mississippi State University in Starkville.

He joined Marshall in 1986 as an engineer in the Systems Dynamics Laboratory, where he advanced quickly through supervisory positions, and in 1998 was named the chief of the Fluid Dynamics Division. In 1998, he was named NASA’s deputy manager for the Military Spaceplane Technology Office, where he worked on space vehicle technologies of joint interest to NASA and the U.S. Air Force.

McConnaughey held various leadership positions of increasing responsibility, and in 2007 was selected as Marshall’s chief engineer. He then served as the director of System Engineering and Integration and the chief engineer of the Exploration Systems Development Division at NASA Headquarters in Washington where he oversaw the integration of the Space Launch System, Orion spacecraft and Ground Support Development and Operations programs.

For his service to NASA he has received three NASA Exceptional Service Medals, a NASA Outstanding Leadership Medal, a Center Director’s Commendation and a Certificate of Appreciation.
