Volos Summer School of Human Genetics 2023

Join us for 4 days of lectures and workshops revolving around genome-wide association studies.


Join us in sunny Volos (Βόλος) on the coast of Thessaly. You will find a range of accommodation facilities around the summer school venue.

Course overview

The Volos Summer School will cover a range of topics surrounding the human genetics of complex traits, with a focus on the computational and statistical analysis of genome-wide data. Areas of focus will be the conduct of genome-wide association studies, meta-analysis of several studies, and the joint analysis of multiple diseases/traits to understand pleiotropy.

The course will be split into seminars and workshops. The former will provide background theory to the topics covered, while the latter will allow students to implement some of the analysis concepts presented during the seminars.

Students will obtain the skills to manipulate and analyse large data sets in a Unix environment and a basic understanding of scripting and programming skills.

Students will also have the opportunity to discuss  their own projects and ideas with experienced researchers in the field. At the start of the summer school, students will be asked to form teams and design a genetic study, which will be discussed at the end of the program and evaluated by the instructors. The best project idea will receive an award.

The main objectives of this summer school are to provide students with a solid grounding in the use of bioinformatics tools, key software, statistical and visualization methods and their various applications in genome studies.

Due to the range of material covered, this is an intense three-day course and will require the active participation of students.


Who can attend ?

The Volos Summer School is intended for early career researchers (graduate students or post-docs) interested to learn about the genetics of complex human traits and gain practical skills in bioinformatics and the analysis of genomics data.

We welcome applications from researchers with a strong background in the biological sciences or a quantitative field (mathematics, statistics, computer science, engineering, etc.).

Attendees should have some familiarity with a command-line tool such as UNIX, R or MATLAB, and have some basic statistical knowledge.

All seminars and workshops will be held in English, and a good command of the language is a prerequisite.

You will need a Google account and Google Drive with at least 2GB free storage space. For more details about the platform please have a look here.
