Jeannine+Marquardt

I am a PhD student at Queen Mary, University of London (QMUL) and working at the Natural History Museum in London (NHM). I work closely together with the groups of Dr Harald Schneider (NHM), Prof Richard Nichols (QMUL) and Prof Andrew Leitch (QMUL). With my project ‘Hybridisation in bluebells (//Hyacinthoides//)’ I participate in the European Marie Curie Initial Training Network (ITN) INTERCROSSING. My network collaborators are Alexandre Blanckaert and his supervisor Prof Joachim Hermisson from University of Vienna, as well as the Statistical Genetics group lead on by Prof Dirk Metzler from University of Munich.

I completed my Bachelor’s degree in Biodiversity and Ecology at the University of Goettingen. Under Prof Gradstein I studied the usage of filmy ferns (//Hymenophyllaceae//) as indicator species for a new tropical forest type, the lowland cloud forest in French Guiana.

For my Master’s degree in Evolution, Ecology and Systematics I joined the University of Munich. During my time there, I worked for Prof Renner as teaching assistant and studied the phylogenetics of //Ibervillea// under her supervision. For my thesis project, I then moved to the statistical genetics group of Prof Metzler and focussed on cryptic diversity in the common European wall rue fern (//Asplenium ruta-muraria//).

During my PhD, I am studying a homoploid hybrid zone in order to gain a better understanding of the impact that hybridisation has on speciation. This involves applying coalescence and selection modelling, but also field and lab work, cytogenetics, morphometric and bioinformatic approaches.
