Mission

Die Arbeitsgruppe Netzwerkanalyse und Modellierung widmet sich der Erforschung molekularer Mechanismen der Phänotyp-Entstehung bei Nutzpflanzen mittels groß angelegter Datenintegration auf genomischer, transkriptomischer, metabolomischer und phänomischer Ebene. In der Praxis entwickeln und implementieren wir maschinelle Lernansätze und Netzwerkanalyse-Algorithmen, die uns (oder anderen) helfen, neue Genfunktionen oder neue Interaktionen zwischen Genen, Metaboliten und Phänotypen zu entdecken.

Einige unserer spezifischen Aktivitäten umfassen z.B. die Implementierung von Deep Learning für die Vorhersage von Pflanzenphänotypen und für die Züchtung, die Entdeckung von Motiven in großen “multi-omic” Genom-Phänomen-Netzwerken und die "Gamifizierung" der Pflanzenentwicklung. Zu unseren bevorzugten Untersuchungsobjekten gehören Getreide, aber wir haben auch eine besondere Affinität zu Nachtschattengewächsen als Modellsysteme für spezifische Fragestellungen.

Darüber hinaus bieten wir statistische Expertise, Lösungen für maschinelles Lernen und innovative Ansätze zur Visualisierung von Daten an, welche die Integration und Interpretation der am Institut etablierten Hochdurchsatztechnologien erlaubt.
