Title: “Mining cohesive and frequent subgraph patterns from rich graphs”.
Abstract: Graphs are increasingly being used to represent systems of interacting entities. In addition to the structural relationships defined by edges, these graphs have attribute data annotating entities and relationships. In this talk, we will present graph mining algorithms for extracting vertex-induced cohesive subgraphs that share common attributes and frequent and maximal subgraphs. These algorithms are employed for mining connected protein-protein interaction subgraphs and frequent co-expression subnetworks from multiple cancer data. We will discuss applications of frequent subgraph mining in generating adversarial malware examples and building robust malware classification systems.

Title: “Contributions towards a safer digital world and more respectful of users rights”.
Abstract: Advances in AI, mobile and Internet technologies have been progressively reshaping our lives over the past few years. Their applications touch today all aspects of our daily lives and include smart systems and services of all sorts and sizes that we used daily to work, receive healthcare, travel and even socialize. These systems collect huge amounts of data about us and exploit it for various purposes that could affect positively and negatively our lives. Even though most of these systems claim to abide by data protection regulations and ethics, data misuse incidents keep making the headlines. In this talk, I present a selection of my previous research works on securing the digital space and making it more respectful of their rights such as the right to privacy and transparency. Explored works include flexible and privacy-preserving data integration, privacy engineering in cyber-physical systems; radicalization and cyberbullying detection on social networks.

Title: “From Sci-Fi to Reality: Realizing Wearable Snake-Shaped Robotic Appendages for Daily Use”.
Abstract: Augmenting humans with robotic appendages have long been envisioned in sci-fi and pop-media as a mean to extend our bodies. Recent advances in robotics have also demonstrated various prototypes that could realize such vision. However, there is a huge gap between existing research within robotics communities and proposed visions, which prohibits the realization of robotic appendages within our daily lives. Especially, research literatures are severely limited in terms of targeted use cases, research methods and evaluation approaches that focus on daily usage. This lecture covers our journey of exploring robotic appendages using an iterative human-centric design approach; starting with in-depth exploration of user’s requirements and expectations, followed by the realization of multiple robotic appendages and their evaluations. Based on our work, we extracted essential design considerations to realize robotic appendages in our daily lives, which emphasis four main domains. Lastly, we discuss the implications of our research outcomes and highlight the lessons-learned from conducting this form of cross-disciplinary user-centered research within the scope of our work and beyond.

Title: “On the Security of Wireless Communication: Practical Physical Layer Algorithms”.
Abstract: The broadcast nature of wireless communication imposes the risk of information leakage to adversarial or unauthorized users. Therefore, information security between intended users remains a challenging issue. Currently, wireless security relies on cryptographic techniques and protocols that lie at the upper layers of the wireless network that requires complex key management scheme in the case of symmetric ciphers and high computational complexity in the case of asymmetric ciphers. Research in physical layer security has attracted significant interest from the research community due to its potential to generate information-theoretic secure keys. In addition, since the vast majority of physical layer security techniques exploit the inherent randomness of the communication channel, key exchange is no longer mandatory. Another direction of physical layer security that can enhance secrecy capacity is by generating and transmitting artificial noise to mitigate the effect of passive eavesdropping attacks. The scope of this seminar is to present novel secret key generation algorithms that exploit the reciprocity of the wireless channel and to discuss how artificial noise can be used to confuse potential passive eavesdroppers.

Title: “Short Block Codes for Reliable Communications within the Coexistence of 5G-NR-U and WiFi”.
Abstract: Unlicensed spectrum offers opportunities for cellular mobile network operators, where traffic can be offloaded from licensed to unlicensed bands. Modern heterogeneous technologies such as 5G New Radio (NR) and WiFi can simultaneously operate on ISM and UNII bands under strict coexistence rules. We will present the application of short, concatenated and product erasure correcting codes to recover missing data in LBT-based systems due to collisions during wireless communication. This technique will enhance spectrum utilization with reduced delay and to achieve reliable communications under LBT.

Title: “Confidential Computing in Cloud Environments – Current trends, and challenges”.
Abstract: Over the last decade the adoption of Cloud Computing has significantly expanded. At the same time the number of Cloud Providers and their service offerings is constantly increasing. Although Cloud Computing enables the long-held dream of computing as utility and it unlocks use cases which were not previously possible, it also introduces new challenges. One of the major challenges of Cloud Computing is data confidentiality, in particular confidentiality of data in use. While confidentiality of data at rest and data in transit has been addressed since the early stages of Cloud Computing, confidentiality of data in use has been addressed only recently through novel technological developments, so called Confidential Computing. This seminar talk gives an overview of challenges Confidential Computing addresses and innovative use cases it enables, and describes the different approaches how Confidential Computing can be achieved. Furthermore, it outlines current trends, i.e., the different solutions offered by the major Public Cloud Vendors, Amazon AWS, Google Cloud Platform GCP, and Microsoft Azure. In conclusion, open challenges of Confidential Computing and potential research directions to solve such challenges are discussed.

Title: “Restore to Analyze: Biomedical Signal Restoration and Analysis”.
Abstract: There is a strong need to “restore” corrupted biomedical signals for an accurate and reliable diagnosis by both machines and humans. Existing studies have focused only on a specific restoration problem, e.g., “denoising”, with a strong assumption on the noise type and severity. However, in reality, biomedical signals are corrupted by a blend of various artifacts. So, in this talk we shall focus on blind biomedical signal restoration using new-generation machine learning paradigms. We shall also glimpse on the future plans on biomedical signal syntheses and transformation for a superior visualization and assessment, all of which will be pioneer applications with ground-breaking potentials.

Title: “Industry Metaverse = Clash of Data, AI and High Performance Simulation”
Abstract:
Understanding the complexity and finding certainty in such uncertain times can deliver major operational advantages for any economical, industrial or scientific assets. A digital twin is a virtual representation — a true-to-reality simulation of physics and materials — of a real- world physical asset or system, which is continuously updated. Digital twin technology, with data at its core, is helping scientists, engineers, biologist or even economist gain control and understanding over their resources and assets. In this talk, we discuss how Mathematics, data, simulation and AI make digital twins possible.

Title: “The Journey of Journal Publishing”
Abstract:
Publishing a research article is a journey! We will discuss challenges and advice on preparing, submitting, and revising research manuscripts to increase the probability of acceptance at a top-tier journal. The insights are based on my experiences as editor-in-chief (EIC) of two journals, the first being Internet Research (Emerald, Impact Factor of 3.017 at the end of my tenure) and currently of Information Processing & Management (Elsevier, Impact Factor of 7.466). The focus will be on the mechanics of the journey, including cover letters, items on a manuscript checklist, what happens to your manuscript once submitted, handling communication with the EIC and other editors, the crafting of the response to the reviewers, the revising of the manuscript, and polishing the accepted article. We will also touch on the influence of citations, impact factors, and the contribution of reviewing to the academic research process in what will hopefully be a discussion more than a presentation. The takeaways will be tactics to improve your chances for a top-tier journal acceptance.
