I joined the Helariutta group at the SLCU in October 2014 as a visitor after finishing my MSc in Biotechnology at the University of Muenster, Germany earlier the same year. In my Masters thesis I investigated the interaction of different sieve element occlusion proteins with a focus on the self-assembly capabilities and reactivity of forisome subunits from Medicago truncatula. In October 2015 I began my PhD in the Helariutta group.

Research Interests

As the sieve elements (the translocating cell type in the phloem) undergo a remarkable maturation including enucleation, my work focuses on early differentiation. This work has several aspects: I’m working with Jung-ok Heo on the high resolution mapping of the spatio-temporal regulatory network in differentiating sieve elements, for which we use FACS and RNA seq of several sieve element specific fluorescent marker lines. Also, I help Dr. Pawel Roszak to understand the redundancy and effect of DOF transcription factors involved in phloem fate determination. Furthermore, I will check the regulatory mechanism in photosynthate conducting cell differentiation in the bryophyte Funaria hygrometrica and identify genes that are potential evolutionary conserved with phloem differentiation.
