Welcome to my webpage !
I'm a PhD student in computational linguistics in Tübingen.
My main research interest relates to the question of how automatic content assessment of authentic learner data can efficiently be performed in order to provide feedback to learners.
I'm working in the projects A4 and T1 in the SFB 833 to find answers to this question.
In addition to my research I have an assistant position with Detmar Meurers that includes teaching courses at the University of Tübingen.
I am the M.A. Study Advisor for Computational Linguistics at the University of Tübingen.
2018/11/22: on Monday, November 26, I will be in a school supervising some language tests; I should be back in time for the office hours at 10 am, but if I should be a bit late this is the reason why
2018/10/12: on October 17 at 17 c.t. I will host a general introduction to the module handbook and exam regulations for master students in computational linguistics; all master students and those interested in becoming one are cordially invited to join us in room 1.13; I will start off with a general introduction and then answer specific questions
2018/10/07: I will be in a school doing empirical testing on Monday, October 8 starting from 7:30. Normally I should be back in time for the office hours, but depending on the traffic I might arrive a bit late. So if you plan to come, please drop me a line so we can schedule a meeting at maybe 10:15 or 10:30 to be safe in terms of time constraints.
2018/09/21: Announcement: no office hours on Monday, October 1 since I will be attending the INDUS network meeting in Essen

I am responsible for the M.A. advising for Computational Linguistics at the University of Tübingen. This means if you have any questions related to the M.A. studies, questions to the exam regulations, admission requirements, etc., please contact me and I will resolve the questions or problems.
Here (link) you can find information about how to get in touch with me.
in requests for M.A. advising, please include information about your subject of study and the degree program according to which you are studying at the moment. Having this information I can give you targeted advice.
Frequently Asked Questions:
Q: Where can I get information about the structure of the M.A. studies in Computational Linguistics ?
A: In the exam regulations and the module handbook on the web page of the Prüfungsamt (link).
Q: Which document should I definitely read carefully before and during the studies ?
A: The most important document for you is the module handbook
- Q: To which module do I need to count my courses specified in the admission requirements ?
A: Module ISCL-MA-02
- Q: How many courses need to be counted in the core/supplementary area ?
A: 45 ECTS in the core, 45 ECTS in the supplementary area. Each area consists of modules with 15 ECTS each, and you need to fulfill each individual module.
- Q: On my admission requirements it is stated that I need to complete the prescribed courses within one year or when first offered. What do I do when the courses are not offered such that I can complete them in one year ?
A: Some courses are only offered every second semester and have admission requirements. In this case take the courses the first time they are offered and in the order they are intended.
- Q: How can I get courses external to the SfS approved ?
A: Please contact me before taking the course. I will check whether it is eligible and inform you about the decision.

A: Send me an e-mail (see Contact) andI will provide you with a template you can use as a starting point.
- Q: From where do I know whether a Hauptseminar at the Seminar für Sprachwissenschaft is from the core or supplementary area ?
A: Take a look at the Campus page or the introductory meeting handout distributed at the beginning of each semester.
- Q: Where can I hear more about the seminars offered at the Seminar für Sprachwissenschaft ?
A: It is very important that you attend the introductory meeting at the beginning of each semester where all the seminars are presented, as well as organizational announcements. Take a look at the campus system to find the exact date for each semester.

I'm working in the project A4 in the SFB 833 as a researcher on the question of how content assessment for learner data can be performed by computers.
This question is especially interesting since language learners, in contrast to native speakers, have only acquired an intermediate state of proficiency in their L2. This results in a high degree of variability in terms of form and meaning in utterances produced by language learners. In the A4 project we explore computational approaches for dealing with this variation in order to assess the semantic content of language learner data.
Besides working on the technical aspects of the CoMiC system (e.g. porting it to uimaFit and DKPro, ...), I wrote my B.A. thesis (link) about how general linguistic properties and the explicit task context can be used to improve short answer assessment of learner language in a reading comprehension scenario there.
In addition I successfully demonstrated the ability of the system to adapt to new domains such as Question Answering, Answer Selection, and Plagiarism Detection.
This and further work in the context of this project is documented in several scientific articles.
Furhtermore I'm working as lead developer on an interactive school workbook with feedback generation (FeedBook) in SFB 833 Transfer project 1 (T1) to refine my technical abilities and gain experience in coordinating bigger software projects. In this project we explore how online scaffolding feedback can be generated in an intelligent, interactive workbook for learning English as a second language. The T1 project combines fundamental research from A4 with an authentic setting in order to advance meaning and form assessment in the cotext of feedback generation. I actively work on all aspects of the system, from frontend development to backend code.
From my work on technical implementations of systems originated a strong interest by me on approaches for collecting, representing, and processing multi-faceted linguistic data produced by language learners. I'm especially enthusiastic about statistical approaches to NLP, formal representations such as in UIMA, feedback generation, and multi-layer web application development for example with the Google Web Toolkit.
