This is a block Pro-/Seminar for Bioinformatics and Computer science students.

Overview (Bioinformatics): Single-cell studies are among the very rising topics of the last few years and will strongly shape future developments of bioinformatic methods. Applying transcriptomics to measure the dynamics of gene-expression under various conditions, on the other side, is already well-established in the scientific literature, and currently experiences another up-surge due to high-throughput single-cell sequencing. In the course of this seminar, we will cover the basics of the different single-cell RNA-seq techniques and swiftly move on to advanced bioinformatics methods that help to understand the sparse single-cell datasets. To this end, we will have a look at the diverse steps of data quality assurance and technical and / or biological bias detection methods, which are necessary to implement effective single-cell RNA analysis pipelines.

Overview (Computer science): Inferring causal (biological) relationships from noisy experimental large-scale data such as single-cell high-throughput sequencing is an on-going challenge. The question is simple: What caused the data to look like we observed it? A concise differentiation between (gene) correlation and technical bias, actual function, and eventually causation is therefore crucial. Effective, i.e. efficient and accurate computational methods promise to deliver an explanation of the underlying perturbations as observed in many phenotype disorders, such as high-mortality diseases like cancer or neurodegenerative diseases such as Alzheimer’s. In the course of this seminar, we will review recent methods and implementations addressing these challenges, while putting an emphasize on the methodological intricacies. Ideal candidates should be highly motivated to gain new knowledge and bring along good skills in maths (linear algebra / statistics), algorithms and data structures, and data analysis.

News: The topics have all been assigned and LSF-registration is now open. Read below for more details.

The Pro-/Seminar was extended to be open to students from the Computer Science department as well. Prospective candidates from CS should contact the tutor immediately via e-mail and list the following details: Name, matriculation number, the number of semesters studied, if a pro-seminar or a seminar is desired, whether you are a bachelor or a master student, and a short statement on how you think you fulfill the requirements for the seminar.

Depending on the current pandemic situation, for the dates listed below, we will most likely have remote meetings via online zoom or Microsoft Teams conferences instead of personal meetings.

Tutor: M.Sc. Fabian Kern
Key dates:

Registration *04.05.2020-11.05.2020: REGISTER HERE
Kick-off meeting [mandatory]08.06.2020, 14:00 remotely via zoom – slides
Deadline to register in HISPOS OR de-register from seminar *29.06.2020 (3 weeks after the kick-off meeting)
Deadline for feedback ** [optional]14.09.2020 (2 weeks before the presentations)
Presentations28.09.2020 remotely via Microsoft Teams
Summary submission deadline05.10.2020 (1 week after the presentations)

* If you want to deregister from the seminar, please send the tutor an email irrespectively whether you (de)registered in HISPOS or not.

** If you would like to get feedback about your slides, e.g. to improve your presentation before the talk, send your slides to the tutor before the feedback deadline. We strongly encourage you to take this opportunity. When asking for feedback the more complete the submitted presentation the more helpful our feedback can be. Thus, try to avoid submitting half-finished slides. Feedback will be provided at least once but at most twice per participant. Also, before sending in the slides, check out our support materials (presentation guidelines, presentation guidelines checklist). You must hand-in a (digital) copy of the completed guidelines checklist at latest when performing the presentation.

Please note: Your slides will make up a substantial part of the final grade. Reading and paying attention to the provided presentation guidelines will help you to get an impression of which aspects are relevant for the evaluation. Disregarding many of the points listed in the guidelines may negatively affect your grade.
