Dr. Stephan ROBERT-NICOUD
Professor, PhD degree in Computer and Communication Sciences from EPFL. Stephan Robert was born in Neuchâtel, Switzerland. He graduated as an engineer (BSc) in microengineering with first honors. He received the ing. dipl. degree (MSc) in electrical engineering (Maillefer Award) and the « Docteur ès Sciences » degree (PhD) with Prof. Jean-Yves Le Boudec, both from EPFL, Lausanne (Switzerland). From 1996 to 1998, he has been a Post-doctoral Research Fellow at UC Berkeley with Prof. Jean Walrand. He worked as a researcher, consultant, engineer and projects manager for many companies during 8 years: Swisscom (Bern), Huber & Suhner (Herisau), ABB (Turgi), GDA (Bern) and Cisco Systems (San Jose, California). Since 2001, he has been a Professor at the University of Applied Sciences (HES-SO), Yverdon. On the political side he has been a « député » (deputy) at the « Grand Conseil Neuchâtelois« (2005-2009). During his Master’s thesis he developed the first prototype of an SSFIP antenna which is manufactured by Huber+Suhner and widely spread over our country. During his PhD, he discovered new models of Markov chains exhibiting self-similarities over a finite timescales. At Swisscom, he was the project leader of « Mobile Unlimited » (which won the highest application distinction, the GSM award in Cannes, March 2005) during the initiation phase. He was also involved in a number of EU projects for traffic engineering, mobility and wireless communications (UWB) aspects. Now his research interests are on artificial intelligence, machine learning, fraud detection, prediction, scheduling, smart caching and storage of spatio-temporal data. He also served as an editor for IEEE Communications Surveys and Tutorials and as a TPC member of many conferences. During seven consecutive years he organized a summer university with SJSU, PES-IT, CSULB, ASU and now with the competitive Seoul National University (SNU). Avisdexperts.
Félicien holds a MSc in mathematics with a minor in computer science from the University of Neuchâtel. Passionate about applied mathematics, machine learning, deep learning, and data science, he wrote his master thesis on persistent homology for topological data analysis, an approach which has been developed to analyze complex datasets. Persistent homology is a method for computing topological features of a space at different spatial resolutions. More persistent features are detected over a wide range of spatial scales and are deemed more likely to represent true features of the underlying space rather than artifacts of sampling, noise, or particular choice of parameters. To find the persistent homology of a space, the space must first be represented as a simplicial complex. A distance function on the underlying space corresponds to a filtration of the simplicial complex, that is a nested sequence of increasing subsets. The mathematical tools used in persistent homology mostly come from commutative algebra, combinatorics, and probability theory. Topological data analysis has a wide range of applications, among which image compression, cancer research, and shape or pattern recognition. Currently, he is involved in an exciting European research project in collaboration with the CHUV (Centre Hospitalier Universitaire Vaudois), the University of Franche Comté, the CHU (Centre Hospitalier Universitaire) Besançon, TechWan (www.techwan.com) and Maincare (www.maincare.com), and he tries to find optimal solutions using deep learning to guide and involve the most appropriate vector (helicopter, ambulance) in the face of an emergency, accident, or disaster.

Research Data Scientist. Cezar Harabula graduated from the French École Polytechnique (ingénieur) and holds a MSc from Eurecom Sophia Antipolis in computer science. He is a software engineer who worked in Silicon Valley and Paris (at Murex or in Astek’s incubator), built his startup, and later obtained a PhD in quantum devices from the University of Basel. The noise-based stochastical analyses he elaborated during his doctoral studies offered precise descriptions of novel electronic transport phenomena in quantum dots. After a deep-learning intermezzo at ETHZ, he integrated the fraud detection project we are running with NetGuardians.

This degree is based on PDEs, control theory, signal processing and deep learning. I’ve graduated from the University of Strasbourg in Pure Mathematics (BSc) in 2018. Since October 2019, I am working on a project with Electricité de France R&D PERICLES to design a deep learning model to solve fluid dynamics problems. (Navier-Stokes PDEs). From May to August 2019, I was an intern at Cross Valorem Luxembourg and I worked on financial models. I also worked on an NLP problem for Electricité de Strasbourg in 2019. My internship at the HEIG-VD starting in January 2020 will be based on setting up an AI-based algorithm for banking fraud detection. »
Master student in Mathematics, IAESTE Intern, Gdansk University (Spring 2020). graduated in the field of Financial Mathematics at Gdansk University of Technology in July 2017 and since then have been working for PwC Poland, Financial Crime Unit. During my first year at the company I was working in the operations department as an AML Analyst. I decided to take one year off before my master degree because of the opportunity to work for such a well-known company straight after my bachelor studies. A few months later, I took part in a project at the University San Francisco de Quito in Ecuador. During my internship in Ecuador I was working on an optimization model for a company delivering liquids. When I came back from Ecuador I changed my career path to join the Technology Stream where I took on the role as a Data Analyst. Since October 2018 I have been studying Big Data at the University of Gdansk. During the summer of 2019 I was enrolled at the University of Macau in Macau, China, Department of Computer & information Science where I was involved in a project based on complex functions visualization using the domain coloring method.
