Jan-Elo Jørgensen
Associate professor,Department of Molecular Biology, Aarhus University
I have researched and lectured extensively on the topic of Molecular Biology of Plants for 24 years. I
was a Post-Doc at the Salk Institute, La Jolla, California 1991-1993. In 2001 I founded and managed
Plantic ApS, a Danish biotechnology company in cancer therapeutics.
My key focus has been cell cycle and development as well as cancer.

Trine Juul
Postdoc, Department of Molecular Biology, Aarhus University
I have 13 years of experience in the field of plant molecular biology of which five years have been
spent abroad at the John Innes Institute, UK and INRA, France. For two years I was employed as a
researcher at the biotech company Plantic Aps. During my career I have been interested in plant
growth and development working with several different plant species and am now involved in setting
up a system where plants can be used to get a better understanding of human cancer diseases.

Stig Uggerhøj Andersen
Postdoc, Department of Moleculær Biology, Aarhus University
During my PhD, I studied symbiotic nitrogen fixation in legumes. As a post doc, my research activity
has been centered on regulation of cell cycle and stem cell activity using the plant Arabidopsis as a
model system. I have pursued this interest first at Plantic ApS and then at the Max Planck Institute,
Tübingen, Germany, before returning to Aarhus University. Currently, I focus on studying the effects
of chemotherapeutic agents by combining genetic and pharmacological intervention and on
optimizing the Arabidopsis platform for this purpose by taking advantage of deep sequencing
