Methodology of Scientific Research

Experimental design for Life Sciences

25 January 2024

This course focuses on theoretical and practical aspects of doing science. In particular we talk about how to design good experiments that can create high-impact knowledge, and how to organize the work so that ideas become reality. It does not require any previous knowledge, only things we learned in high school.

This will be a very practical course. Of course, there is nothing more practical than a good theory. But we will also teach good practices for everyday projects.


Here you will find the slides from the classes and other supplementary material. Notice that some things are said but not written, so you better take good notes. We recommend taking notes with pen and paper using the Cornell Method.


Homework is an integral part of this course, since we want to match theory and practice. Besides, without practice we tend to forget more often. All homework should be sent to before the deadline to get a grade. Please be careful, otherwise you will get a grade zero.


By regulation from the Rectory, students need to attend at least 70% of the classes. If you cannot attend, you must deliver all homework on time. Late submissions will not be accepted.

The attendance book is updated every class and can be seen in Google Sheets.


In the first part of the semester I want to talk about Science in general, and about measurements in particular.

The midterm exam is usually a homework, so there is no time pressure. After that, I want to talk about good practices on personal project management
