GA Synergy Award

The synergistic effects involved in the action of natural products are key for their medicinal use. Research on these actions has been revolutionized in the past decades by methods quantifying synergy and by genomics techniques. The GA synergy award is aiming to create awareness for research on these effects, by awarding excellent research in the field.

The award, at present connected to a price sum of 1000 €, will be handed over within the frame of the annual GA congress, as the other GA awards, with a short lecture on the work.

Your submission (including publications or graduation theses, a letter explaining the relevance for the field, and a CV) is welcome. Please send it by email to Cornelia Kern ( until April 4, 2024.

The jury consists of experts in the field and the president and the vice presidents of GA. The jury may invite further subject matter experts for the evaluation of the submissions. Each jury member independently will rate each work according to the three categories scientific excellence, relevance for the field and quality of the methodology and presentation. Based on this, the winner will be chosen in the frame of an online meeting of the jury.
