Invited Speakers

Prof. Dr. Franck Leprévost, University of Luxembourg

Franck Leprévost is professor at the University of Luxembourg (UL). He was before professor at the University of Grenoble (France), researcher at the CNRS Paris (France), at the Max Planck-Institut für Mathematik and at the Technische Universität Berlin (Germany). He received his PhD and Habilitation in mathematics in Paris in 1992 and 1997. He was Vice-President for International Affairs and Organization (2005 – 2015) of the University of Luxembourg, and introduced it to International Rankings (UL is the most international worldwide, 11th among the young universities, and is part of the top-200 worldwide according to Times Higher Education). His research major is Algorithmic Number Theory and Cryptology. He is the author of over 50 highly cited papers, co-editor of 2 books, and co-author of chapters of 3 books.

Prof. Leprévost has vast experience in international research and organizational projects. He has been involved in international IEEE standardization activities (like the IEEE-P1363 worldwide standard on Public-Key Cryptography); he served as an expert for the European Parliament on security technology for digital media; he was a member of the scientific board of the National Research Fund of Luxembourg. He delivers around 8 international talks per year as an expert in mathematics, cryptology, digitalized industry, and internationalization of universities.

Besides his huge academic and business experience, Franck is known as the author of several plays for theatre including the recently published (on Amazon in French and Russian) “La chambre de larmes”, which has been successfully staged by the Theatre of Esch (Luxembourg) in 2018.

Topic: James Bond's most secret weapon


Before creating James Bond in 1952, Ian Fleming (1908-1964) conducted intelligence activities for the UK. During WW2, among other things, he initiated the so-called "Operation Ruthless", a plan aiming to obtain the Enigma codes used by the German Navy. The plan was never implemented, much to the annoyance of Alan Turing, who was at that time heading the cipher school at Bletchley Park. Nowadays it is known that the efforts made by the team of mathematicians at Bletchley Park to break Enigma saved numerous lives, and probably shorten the war. Since this dramatic period, security of communications has known a huge development, even a kind of "revolution" in the mid 1970's. If during thousands of years symmetric-key cryptography mainly dominated the way messages were safely exchanged, the mid-1970's saw the emergence of a new concept: Public-Key Cryptography. Cryptology progressively left the sphere of art to become a science. The security of public-key crypto-systems relies on the difficulty to solve mathematical problems. Nowadays, there are mainly two problems used in this setting: the Integer Factorization Problem (IFP) and the Discrete Logarithm Problem (DLP) in well-chosen groups. In the mid-1980's, Koblitz and Miller (independently) proposed to use elliptic curves, and defined the Elliptic Curve Discrete Logarithm Problem (ECDLP). According to today's knowledge, ECDLP is algorithmically safer than the other public-key crypto-systems. The increasing importance of mathematics in secure communications a posteriori legitimates the provocative title of this hopefully beautifully illustrated and entertaining conference.


Dr. Vlatko Davidovski, Associate Director at Cognizant Consulting, Digital Strategy (Switzerland), and Digital Transformation Lead at DigitalLab@HSR.

Vlatko Davidovski leads numerous strategic consulting engagements covering Business and Digital Transformation for marquee global industry players across industries and geographies. He specializes in helping enterprises gain competitive advantage by leveraging the power of Digital and transforming companies’ capabilities and workforce. In his former career, Vlatko established an Innovation Lab for an international oil-and-gas company in collaboration with Peter the Great St.Petersburg Polytechnic University. In collaboration with the exceptional talents from this university, Vlatko brought to market novel digital products in the area of passive seismic surveys, leveraging advanced computational technologies, geographical information systems & satellite imagery, 3D visualization, sensors, and more.

Besides a PhD degree in Economics with research focus in Innovation, a BSc. Degree in Computer Science and a Diploma in Management from the Peter the Great St. Petersburg Polytechnic University in Russia, he also holds a Master’s degree in Computer Science from the Swiss Federal Institute of Technology (ETH Zurich) where he invented a new IoT Platform.

Vlatko’s passion is bringing Digital Innovation to the real world and helping Global enterprises reinvent themselves for the Digital Age. His evangelic talks on digital transformation receive excellent feedback from international audience all around the world. Vlatko is also a guest lecturer on the topics of Digitalization at the University of Applied Sciences Rapperswil, HSR and Peter the Great St.Petersburg Polytechnic University.

Topic: Exponential Innovation through Digital Transformation


In this talk the speaker will demystify the meaning of Digital in the context of the next industrial revolution happening today. You will understand what is Digital and how it enables rapid, Exponential Innovation. You will learn about its risks and benefits and get insights on how to apply it in real life.


Natalia Bogach is an Accociate Professor at Peter the Great St. Petersburg Polytechnic University Computer Science Institute.

In year 2000 she made her Ph.D thesis on wavelets for signal processing. For more than 15 years she participates in international educational projects led by SPbPU. In recent years she is teaching English for special purposes (ESP) for master students. Her research interests lay on the crossroad of speech processing and linguistics. The latest projects cover computer-assisted language learning focused on intonation and prosody and intonation-based speech semantic analysis.

Topic: Languages and cognition: towards new CALL


We address cognitive models and prototype theory in context of foreign language learning and examine some ideas that seem to favour Computer-assisted language learning tools (CALL tools) evolution alongside we present a software prototype of a learning environment where prosody and intonation are primary learning goals. Project methodology uses phrasal intonation contour as an item at basic level of categorization. Thus, CALL is not limited to mere digitalization of learning process by transferring traditional techniques of managing language-related data with the use of computers but creates totally new use cases that are aimed to overcome formerly infeasible challenges in language teaching and learning.
