*Alumna is the nominative plural of alumnum, which means student in Latin. This a gender neutral (or, better said, gender neuter) version of the gendered words alumni and alumnae.



Natural Language Processing

ETH Zürich Spring 2021
This course presents topics in natural language processing with an emphasis on modern techniques, primarily focusing on statistical and deep learning approaches. The course provides an overview of the primary areas of research in language processing as well as a detailed exploration of the models and techniques used both in research and in commercial natural language systems.

Thesis Projects

If you are a BSc or MSc student at ETH Zurich interested in writing your thesis with us, we would be delighted to hear from you! Unfortunately, we do not have the capacity to consider students from outside ETH for thesis projects. Our research revolves around theoretical and applied problems in Natural Language Processing, Computational Linguistics, Machine Learning and Statistics. To obtain a better understanding of what currently interests us, we invite you to check our recent publications. However, feel free to express interest in any topic you think our group might be well suited to advise you on: Just because we have not yet looked into a topic does not mean we are not interested in it or willing to become interested in the topic.
Please send an email to ryan.cotterell@inf.ethz.ch with CC to clara.meister@inf.ethz.ch and niklas.stoehr@inf.ethz.ch and state either [bachelor’s thesis] or [master’s thesis] at the start of the subject. For us to get to know you a little, please write a paragraph introducing yourself and why you are interested in working with us. It would help us a lot if you also provided a list of four or five more concrete topics that you are interested in. We will try our best to find a project that suits your interests. We are looking forward to receiving your inquiry!

Joining Our Lab

Thank you very much for your interest in joining our group – we would be delighted to hear from you!

If you are interested in working with us as a Master’s student, please see here. Ryan has previously co-advised Master’s students on NLP topics with Mrinmaya Sachan and others, if co-advising is an option you would like to pursue. At Cambridge, Ryan co-advises MPhil students with Simone Teufel. We are looking forward to receiving your inquiry!

If you are interested in joining us as a PhD student: we do get a lot of emails about joining our lab from super interesting, well-qualified applicants who we would be very happy to have as research colleagues. However, there has been unbridled exuberance over joining our group and we grew quite quickly. Thus, for the foreseeable future, we can only accept new PhD students under one of the following circumstances:

  • Consider that ETHZ is part of the ELLIS PhD program, which supports PhDs and postdoctoral fellows by providing access to leading researchers through boot camps, summer schools and workshops of the ELLIS programs. You can apply for admission through the centralized application portal; the deadline is the 1st of December 2020. Our lab works closely with CopeNLU headed by Isabelle Augenstein at the University of Copenhagen; applicants who apply through ELLIS are encouraged to tag both Ryan and Isabelle as they are both part of the ELLIS network

  • Ryan is also core faculty member of the newly-established ETH AI Center which offers fully-funded PhD and Post-doctoral fellowships. Please apply here and describe how you intend to take an interdisciplinary perspective on NLP.

  • If you are interested in NLP at ETHZ and do not yet have a Master’s degree, please consider applying to ETHZ’s direct doctorate program. You should tag Mrinmaya Sachan and Ryan and that you are interested in NLP.

  • If you have a previous working relationship with members of our group or there is a co-advisor who has a previous working relationship with our lab.

Note on our research focus and collaboration style: we don’t do leaderboard science or chase state-of-the-art numbers on ephemeral datasets. If you’re okay with that, awesome! You’ll probably fit right in. I spend a lot of time with those I collaborate with. I am a hands-on advisor who writes large swathes of our papers. I am also known to have a strong opinion on modeling aesthetics, code style and experimental design. That may not be what you are looking for during your PhD, which is perfectly fine. This style of advising takes up a lot of my time, which is already stretched quite thin as it is, and, hence, the need to limit admissions. In many ways, I am more of a collaborator than a traditional advisor.
