News

Welcome to my personal homepage.

I am Professor of Algorithms and Didactics at the Department of Computer Science of ETH Zurich; on the occasion of my appointment, I had the opportunity to answer a few questions.

I studied computer science (with minor psychology) at RWTH Aachen University and information technology at QUT Brisbane, receiving my Master in 2008 and my PhD from ETH Zurich in 2012. After that, I stayed at ETH as postdoc, and then lecturer and eventually senior scientist. Additionally, I taught at other institutions, for instance, at the University of Zurich, where I regularly read the course Foundations of Computing II from 2014 to 2020. In 2016, I was offered a position as assistant teaching professor at the University of Illinois, but I had to decline due to personal reasons. From 2018 to 2019, I worked as a lecturer at PH Graubünden, and then became head of its department “Schule und Technik.” Before establishing my group at ETH, I was Professor of “Fachdidaktik Informatik” at PH Graubünden.

My major research interest is in how to nicely communicate some of the basic ideas and concepts of computer science to students of all ages, the focus being on computational thinking. As a result, I teach at many different levels, starting at primary school. Complementing this, I give further education courses for computer science teachers; for instance, I am in charge of the CAS programs “Informatik und Informatikdidaktik” for teachers at primary or lower-secondary level.

In theoretical computer science, my main topics of interest include approximation algorithms for hard optimization problems, reoptimization of optimization problems, and advice complexity in different setups and environments.

I enjoy hiking, snowboarding, traveling, L^AT_EX, Linux, Perl, and Python.

I am married to the love of my life, and we have two wonderful daughters.

Some more facts:

• In Arabic, my name is دينيس; it is 丹尼斯 in Chinese; デニス in Japanese; 데니스 in Korean; and ДЕНИС in Russian.
• My Erdős number is at most 3 (D. Komm ↔ J. Edmonds ↔ N. Alon ↔ P. Erdős).
• My mathematical genealogy can be found at the Mathematics Genealogy Project.

Curriculum Vitæ

In February 2010, I was visitor at King's College (with Kathleen Steinhöfel), in June 2011 at RWTH Aachen University (with Peter Rossmanith), in March 2015 at Comenius University (with Rastislav Královič), and in July 2018 at Stanford University (with Gio Wiederhold).

I was chair of ARDA 2019, an MFCS satellite workshop on advances in reoptimization and dynamic algorithms. This year, I am chair of OLAWA 2020, an MFCS satellite workshop on online algorithms with advice and related models.

Also, I was (still am) member of the program committees of

Furthermore, I reviewed submissions to Algorithmica, Algorithmic Operations Research, Fundamenta Informaticæ, Informatics in Education, Information Processing Letters, International Journal of Foundations of Computer Science, Journal of Combinatorial Optimization, Journal of Scheduling, Parallel Processing Letters, RAIRO – Theoretical Informatics and Applications, Theoretical Computer Science, Theory of Computing Systems, CIAA, COCOA, COCOON, CSR, DLT, ESA, ICALP, ICER, IFIP TCS, ISAAC, ISSEP, LATA, MEMICS, MFCS, SEA, SIGCSE, SOFSEM, STACS, WALCOM, WAOA, and WG.

Teaching

I am giving a Python programming course with special focus on preparing for the Swiss Olympiad in Informatics.

In summer 2014, I gave a course on computational biology at Volkshochschule Zürich; lecture notes (in German): Summary 1, 2 (Handout), 3 (Handout), and 4.

Since 2010, together with colleagues from the ABZ, I gave some programming lessons for elementary school students at, e.g., Kantonsschule Solothurn, Primarschule Domat-Ems, Primarschule Saas im Prättgau, and Schweizerische Alpine Mittelschule Davos.

	Algorithmisches Denken in der Primarschule Computational thinking is understood as a set of processes that aim to solve problems in a structured way. The focus is usually on the development of an algorithm, that is, a sequence of instructions whose strict observance solves a problem (or an instance of the problem). While executing an algorithm does not require creativity or intellect, these are paramount when developing an algorithm. In this book, we present 26 suggested lessons that cover different aspects of computational thiking and can be used in different school subjects. The focus is on designing lessons that build and promote sustainable problem-solving skills. Contains 123 exercises with solutions. ISBN: 978-3-033-09210-5, PHGR Collana 2022, 184 pages; view as BIBTEX.
	Informatik – Programmieren und Robotik The book is for secondary schools and contains an introduction to programming in Python (TigerJython), starting with the Turtle, moving to strings and lists, and finally robots. It starts at the very beginning, no prior knowledge is assumed. Concepts such as loops, variables, functions, Boolean values are introduced in small steps and with care. Numerous examples are complemented by a large number of exercises (and solutions). Moreover, there is a wealth of advanced exercises (and solutions) available online. Contains 307 exercises with solutions. ISBN: 978-3-264-84595-2, Klett und Balmer Verlag 2021, 246 pages; view as BIBTEX.
	An Introduction to Online Computation – Determinism, Randomization, Advice From the cover: “This textbook explains online computation in different settings, with particular emphasis on randomization and advice complexity. These settings are analyzed for various online problems such as the paging problem, the k-server problem, job shop scheduling, the knapsack problem, the bit guessing problem, and problems on graphs. This book is appropriate for undergraduate and graduate students of computer science, assuming a basic knowledge in algorithmics and discrete mathematics. Also researchers will find this a valuable reference for the recent field of advice complexity.” Contains 101 exercises with solutions. ISBN: 978-3-319-42747-8, Springer-Verlag 2016, 349 pages; view as BIBTEX.
