Thank you so much for participating in the course!
We hope you enjoyed it.
Talks can be accessed on the website. Take a look at the Videos' tab for more details.


Advances in genomics, transcriptomics and sequencing technologies have contributed immensely to discovering molecular alterations that develop into potential biomarkers and therapeutic targets. But how do we know whether these alterations play a causal role in a particular phenotype or disease? We test it by modulating gene activation, repression, expression or even inserting a candidate mutation. 


With the advent of large-scale gene editing technologies, especially those using CRISPR/Cas9, a specific set of genes of interest, or even an entire genome, can be modulated at once in a population of cells. This strategy has been very successful for understanding gene function and uncovering cellular dependencies. 


This course is free of charge and open to graduate students, post-docs, and other participants interested in learning how to perform CRISPR/Cas9-based screens in mammalian cells.

* It is not about learning how to modulate one gene of interest in a cell model. It's about learning how to modulate several genes at once to find out which one is your gene of interest. 


  • Concepts of CRISPR/Cas9 and available tools and applications

  • Using CRISPR/Cas9 for drug discovery

  • Design of target specific CRISPR/Cas9 tools

  • Confirmation and validation of genome-edited cell

  • Concepts of CRISPR/Cas9 screens and applications

  • Designing and performing a CRISPR/Cas9 screen

  • Bioinformatics strategies to analyse CRISPR/Cas9 screen data

  • Strategies for screen validation 

  • Limitations of CRISPR-based screens, strategies to troubleshoot experimental steps


This virtual course will take place between the 15th and 17th of September, starting at 10:00 am (GMT-3/Brasilia).

We will use Zoom for the lectures and discussions, and Slack for instant messaging of instructors and participants. 

The course lectures will be followed by discussions between participants and instructors and will be presented live.

Some material will be recorded but participants must be available to attend sessions at these times.


On Day 1, we will have three lectures by renewed scientists with extensive experience in the field covering topics from the basics of CRISPR/Cas9 strategies to how to use CRISPR for drug discovery.


On the second and third days, participants will learn how to design, execute, analyse and validate a pooled CRISPR/Cas9 screen. Important technical knowledge of all steps will be discussed, including limitations, strategies for troubleshooting experimental steps, and quality control of the reagents, libraries and datasets.


At the end of the course, participants will have the opportunity to discuss in detail a specific idea or example of CRISPR/Cas9 screens with the instructors. This workshop will be offered to a limited number of participants, preferably those who attend the full course, are familiar with CRISPR/Cas9 strategies and plan to perform a screening in the short term.
