Invited Speakers

Leo Marcelis 

Leo Marcelis is full professor at Wageningen University where he leads the chair group Horticulture and Product Physiology. The group comprises about 12 staff members, 20 PhD candidates, 5 postdocs, and a number of guest researchers; each year about 35 students conduct their thesis study (a 6-month research) at our group. This is the only academic group in the Netherlands which focusses on horticulture and holds a strong position in horticultural research and education. The focus of the group is on greenhouse horticulture, vertical farming and the post-harvest quality. Responses of physiological processes to the environment are studied aiming to predict and control the phenotype of the plant and plant products. Growth and development of plants as well as product quality are studied as emergent properties of underlying physiological and genetic processes. Three major research themes are discerned: Photosynthesis, morphogenesis and product physiology. Within these themes, research fields such as phenotyping, LED light regulation of plant processes and functional-structural plant modelling are gaining increasing prominence. Leo has 30 years of experience in experimental and simulation research on plant growth and functioning. His main expertise is on physiology, growth and product formation of plants and plant organs. In particular fluxes of assimilates, water and nutrients in the plant, sink/source interactions and partitioning among plant organs in response to environmental growth conditions are subject of study. His research contributes to sustainable horticultural production while improving crop production and quality; this includes saving of energy, efficient use of (LED)light, efficient use of water and nutrients.He has (co-) authored more than 90 scientific articles with an H-index of 29 (according to Web of Science) and over 250 articles for growers. He is chief editor of the section Crop and product physiology of Frontiers in Plant Science

Information for poster presenters

Development of Poster & Oral Presentations Gallery

The Gallery features an elegant display of all the e-posters & oral presentations which are properly indexed and can be filtered or searched.

E-posters “private virtual room”

Each poster presenter is given a private ‘virtual room’ to which people can request access during the designated poster session. The presenter can then present via camera, microphone & screen share while the attendees can participate in writing or by microphone.

*e-posters will be delivered in a specified format


For the poster presenters, we are going to need:

  • The actual e-poster as a PDF file (converted .pptx), landscape orientation. Clattered text and small fonts are to be avoided. Attached you can find a suggestion, just to consider that your poster will be available through a pc screen (of course you can always zoom in/out). Your PDF file will be available throughout the event.


  • Regarding FLASH POSTER presentation

We have allocated time space of 3 min for each poster presenter, in order to have his/her own time to introduce their work. I understand that some of you, might not willing to have the flash poster presentation (only the normal PDF format)

However, for those who would like (as we strongly suggest you this), we would like to receive your video presentations, three minutes .mkv or .mp4 video of 720p quality, recorded via Zoom or equivalent platform, preferably displaying both the presentation and the presenter simultaneously. The use of Powerpoint’s recording feature is discouraged.

You need to use wetransfer or an equivalent file transfer service, for to provide us your video and your PDF, 10 days before the conference (deadline is 9/3/2021, otherwise we will probably not be able to merge all the files in a single video, uploads, tests etc etc.) at
