Plant-vector-microorganism researcher
CV / academic profile
PhD candidate at Agroscope Changins and the University of Geneva, working at the intersection of plant biology, entomology, plant pathology and disease ecology.
My current research examines how grapevine cultivars, insect vector performance and phytoplasma population structure shape Flavescence dorée dynamics in agricultural systems.
Projects are organised by scientific question and research environment rather than by promotional claims.
PhD research
Agroscope Changins and University of Geneva
Research on cultivar-dependent Flavescence dorée epidemiology, Scaphoideus titanus performance and behaviour, host plant resistance and phytoplasma population genetics.
Master's thesis
Agroscope, Switzerland
Independent experimental work on fungal endophytes, mycovirus status, stress bioassays, horizontal transmission attempts and molecular verification by DNA/RNA extraction, PCR and RT-PCR.
Bachelor's thesis
INRAE, France
Laboratory preparation of plant samples for metagenomic analyses and literature synthesis on grapevine-associated microbial communities.
Research internship
Association Technique Viticole de Bourgogne
Statistical exploration of soil physicochemical data, correlation analyses and principal component analysis in relation to vineyard decline symptoms.
