For Chris Brzuska, truth and understanding are supreme virtues

20. September 2018

What kind of research do you do?

In April 2018, I started as an Assistant Professor at both the Department of Mathematics and Systems Analysis and the Department of Computer Science. My research is about cryptography and its connections to IT security, verification, complexity theory, algorithms, and discrete mathematics.

For four years already, I have been part of a vast, collaborative effort in analysing and standardising a new version of the TLS protocol. It’s the main protocol for secure communication on the internet, for instance online banking.

Our informal group includes experts from both industry and academia. The design of the protocol for secure communication is a huge task, and we are now in the final stages of the project. One of the difficulties is backward compatibility: we need to make sure that the new protocol is compatible with the old versions but does not inherit their security weaknesses.

How did you become a researcher?

When I finished high school, I had plans of becoming a very successful banker. Although the banking business was a lot of fun, I realised I was not really accelerating my personal growth. After only six months in banking, at the age of 19, I decided that instead, I want to become a researcher in mathematics.

I studied mathematics in Germany and in Southern France. During my master’s studies, I ended up in a computer science class designing secure cryptography against arbitrary and adverse algorithms. I enjoyed that a lot.

Marc Fischlin, the professor of cryptography at Technische Universität Darmstadt, offered me a PhD position in the same research area—and I accepted the offer. Soon I ended up at the Institute for Advanced Study in Princeton for six months, followed by Tel Aviv University and Microsoft research in Cambridge.

Finally, I started as an assistant professor for IT Security Analysis at the Hamburg University of Technology where I worked closely with NXP Semiconductors for two and a half years before moving to Finland and Aalto University.

What are the highlights of your career?

I rather enjoy the highlights every single day. I feel very lucky and grateful that I can interact with great people in a way that is beneficial for both them and myself.

What is the most important quality for a researcher?

In my opinion, a good researcher is interested in and committed to truth and understanding.

I find it meaningful and fulfilling that research allows me to grow my understanding, not only of cryptography, but of many other topics as well. In teaching, I have the chance to help my students grow their ability to understand, regardless of the topic. I find it very rewarding.

What do you expect from the future?

During the interview process, I came to Finland for several days and felt comfortable. Already then, I had a very strong gut feeling Aalto will be a good environment for research and teaching—and me personally.

I have started to collaborate with my colleagues in discrete mathematics, algorithms and IT security, and I have already taught my first class. I can now confirm that Aalto is a good environment for research and teaching—and I look forward to continue enjoying to be here.

Ahti Salo is the Espoo Ambassador of 2018

29. August 2018

Professor Ahti Salo is an internationally known and respected expert in operations research and an active member of Finnish and international associations in his field.

Professor Salo is the head of the Systems Analysis Laboratory research group in the Department of Mathematics and Systems Analysis. He has developed methods to support risk management, efficiency analysis and decision-making, and has led numerous projects in cooperation with companies and public organisations.

Currently Salo is the Principal Investigator of the six-year Platform Value Now project funded by the Strategic Research Council of the Academy of Finland. This project studies the platform economy from different perspectives. He is a member of the Board of Directors of the Society of Scientists and Parliament Members (Tutkas) and the Foresight Steering Group appointed by the Prime Minister’s Office.

”It has been fascinating to see how mathematical models help to foresee the development prospects of a rapidly developing platform economy and manage risks of cybersecurity,” says Professor Salo.

In addition to scientific positions of trust, Salo has taken part in the organisation of several international conferences in Finland and abroad. In 2017, he was the main local organiser of two international conferences held at Aalto University´s Otaniemi campus.

The Finnish Operations Research Society is considering applying to host the main European operations research conference in Espoo in 2022. Should this come true, the conference would bring 3000 participants to Finland.

“With the new metro line connecting Espoo to capital Helsinki and the development of the Aalto University campus area, Espoo is, by all accounts, an attractive destination for this type of a larger conference”, says Salo.

Agile security for cloud systems? Moti Yung to give a HAIC Talk at Aalto

12. June 2018

Yung is particularly known for coining the term ‘cryptovirology’ and the principles behind it. At his HAIC Talk he will explain how, in ‘the cloud era’, software design and security tool development should be able to keep up with the constantly evolving ecosystem and take note of how cloud systems keep evolving.

yung.pngAdhering to what he calls “agile principles” could also protect cloud systems from attacks and breaches.

‘In an environment where software development, updates and projects are always ongoing, also the cryptography and security designer should be in a state of adaptation to the system's evolution. I will demonstrate this in my talk based on a heavily-used real-world application,’ says Yung, referring to Google’s Advertisement Exchange, which supports the company’s multi-billion-dollar digital advertising.

Designing security tools and cryptographic solutions with the ever-extending scope and inevitable scaling up of the cloud system – such as Google’s Advertisement Exchange, Yung’s focus point in the upcoming talk – would be a way to avoid overly complex changes and loads of development overhead later on.

Yung finds an analogy of the ‘agility principle’ even for keeping every-day users safe from ransomware and all other kinds of attacks.

‘The two things people often think of only as disturbances – systems updates and backups – are in fact most essential! If everyone took care of them frequently, the window of opportunity for attackers would narrow considerably,’ reminds Yung.

Yung’s work on ransomware – the hijacking of systems or data from users or organisations and issuing demands for ransom for releasing the data – also becomes increasingly relevant with the current internet of things trend. The ‘things’ will enable new kinds of security breaches and attacks and prevention tactics need to be planned well in advance.

‘The merging of computing and physical devices will lead to new attacks where ransomware will be replaced by physical consequences.’

‘Any element of the new IoT systems will be a target, and there is not enough investment in their security. Ransomware could cause a man-made disaster if we do not secure the system-level infrastructure,’ believes Yung.

He also cautions that artificial intelligence applied without safety and security in mind will lead to attacks.

Aalto ranked #5 in Europe in empirical operations and supply chain management research

14. May 2018

Aalto University ranked #5 in Europe in the core area of empirically focused research and #11 overall.

Globally, Aalto University was ranked #30 in empirical research in the field in March. More details of the rankings, see SCM Journal List.

‘We are proud of the stream of research that has resulted in a series of publications, for example, in Journal of Operations Management, the number one journal in the field,’ says professor Risto Rajala, Head of the Department of Industrial Engineering and Management.

In comparison to many large universities, Aalto stands out with long-standing and trusted relationships with industrial partners. Thanks to these, much of academic research at Aalto grounds on real-life data on empirical cases and can contribute to grand societal challenges: sustainable growth in industrial operation and the technology-driven transformation of business around the world and across industries.

‘Our particular strength is empirically focused research conducted in close collaboration with industries. Ranking results are not our objective in itself, but they do signal a trajectory that is based on both great talent and hard work in all areas of empirical research: systematic data collection, meticulous analysis, insightful synthesis and visionary crystallization,’ Rajala recounts.

Operations and service management research at Aalto benefits not only from close industrial collaboration but also from transdisciplinary scientific approach and research methods.

“Many departments and groups at Aalto contribute to this field. In addition to the faculty of Industrial Engineering and Management, professors and researchers from the departments of Mathematics and Systems Analysis and Information and Service Economy are integral to our effort,’ notes Rajala.

Education in the field aims to instill collaborative orientation and scientific curiosity into students from the get-go.

‘Our students learn by doing: through real-life cases and research assignments. Our degree programs are rooted in strategic management, entrepreneurial leadership, and digitalisation of operations and services. Top students are often invited to do their master’s thesis research in actual industry projects, and they are capable of conducting analytical research that is both well-grounded and rigorous.’

The SCM Journal List ranking of empirical research is based on output in journals that are primarily empirically focused (including Decision Sciences Journal, Journal of Business Logistics, Journal of Operations Management, and Journal of Supply Chain Management). The ranking of analytical research is based on output in journals that are primarily analytically-focused (including Management Science, Manufacturing and Service Operations Management, Operations Research, and Production and Operations Management).
