Matthias Aßenmacher
About
I am a postdoctoral researcher at the Chair of Statistical Learning and Data Science (Dept. of Statistics, LMU) and the NFDI Consortium for Business, Economic and Related Data (BERD@NFDI). I obtained my bachelor’s degree in Economics from LMU in 2014, afterwards, I turned to Statistics (with a focus on social and economic studies) and obtained my Master’s degree in 2017 (also from LMU). In October 2021 I finished my PhD at the working group Methods for Missing Data, Model Selection and Model Averaging under the supervision of Prof. Dr. Christian Heumann with a focus on Natural Language Processing. I lead the Natural Language Processing focus group at SLDS and I am part of the Causal and Fair Machine Learning focus group. Further, I am one of the main maintainers of the course Deep Learning for NLP that is jointly developed at LMU Munich and the University of Vienna.

Research Interests

Thesis supervision
I supervise theses on various topics related to NLP. Please read the following information before writing me an e-mail:
- If you are interested in writing your thesis under my supervision, please include the following information in your e-mail
- your field of interest and at least a tentative idea for the direction of a potential thesis topic
- a CV, and your current transcript of records
- a planned starting date for your thesis (you should also bring some time for developing and refining a research idea, so do not expect to start in e.g. one week)
- Disclaimer: Before you apply for a thesis topic regarding NLP make sure that you fit the following profile:
- Willingness and ability to engage in a topic which (potentially) requires a notable amount of self-study, since it is normally not part of the regular curriculum of your studies in statistics.
- Readiness to do quite some programming (most probably in Python)
- Please include the following information in the email mentioned above: Previously experience/attended classes on NLP, deep learning, machine learning, and programming.
- This is not meant to discourage you from writing your thesis on NLP, but rather to get expectations straight in advance.
- If you want to apply for supervision of an external thesis, please also include the following information in your email:
- A clear formulation of the thesis goal from an academic perspective of ~1 page (It should not be a pure business case, such projects are better suited e.g. for the Consulting module)
- Information on the external partner, data availability (detailed please), computational resources supplied by the project partner (if applicable)
- Again: Not meant to discourage you or to set any artificial barriers, but to get expectations/goals straight in advance.
A selection of theses I recently supervised (partly together with Christian Heumann) can be found here.
