Erik Smets

I am fascinated by flowering plants. In concrete terms, I am very interested in defining good characters - morphological, anatomical as well as phytochemical and molecular - to classify flowering plants into predictive groups that reflect their phylogeny. My MSc project was on defining placentation types, seed types and nectaries. In my PhD thesis, I continued to study the nectaries of flowering plants. Both degrees were obtained at the KU Leuven (Belgium). From the beginning of my career, I had many management tasks and a heavy teaching load, two aspects of my professional life that I found very rewarding, also from a research perspective.

Research
interest

Initially I was fascinated by the huge diversity of floral morphology. Later, my research interests expanded to include floral development, pollen morphology, fruit and seed morphology, and wood anatomy. Monographic studies, still crucial for the inventory of the Earth's biodiversity, also became an important topic in my research group. The introduction of molecular systematics provided a new framework for the understanding of the evolutionary relationships of plants.

I strongly favour a multidisciplinary approach that combines morphological characters with DNA sequence data and evolutionary developmental genetics (what I like to call molecular morphology), because integrative systematics will ultimately lead to better insights into character evolution and understanding of the evolutionary history of flowering plants.

Current
topics

As former Scientific Director of Naturalis, one of my main tasks was to make our motivated group of scientists more effective. For a number of years, my direct involvement in research has been limited and therefore all my PhD students have been supervised by a very dedicated day-to-day supervisor (co-promotor). Being involved in the following PhD project is very rewarding as it allows me to stay in touch with current research.

Ongoing PhD project (preliminary title)

Unraveling evolutionary patterns in the microscopic wood anatomy of two tropical clades. (Beckers, V.; co-promotor Lens, F.)

Teaching
activities

In 1999 I obtained a teaching certificate at KU Leuven (Onderwijskundige Vorming Docenten), and in 2012 I obtained the certificate Basic Teaching Qualification (BKO) from Leiden University).

Apart from some guest lectures, for example in the courses 'Diversity of Algae, Fungi and Plants' (3rd year Biology, KU Leuven) and 'Plant Families of the Tropics' (Master Biology, Leiden University), I taught 'Anatomy' in the course 'Tree of Life' (1st year Biology, Leiden University) and 'Evolutionary Developments' in the minor 'Biodiversity and Natural Environment' (3rd year Biology, Leiden University).

Public
outreach

I have regularly been invited to speak on plant systematics, the classification of flowering plants, or to introduce Naturalis Biodiversity Center. Examples are:

Naturalis Biodiversity Center: Museum, Collection Infrastructure and Research Institute. Chiang Mai University, Thailand (2016).
Naturalis: More than a Museum. Visit by bachelor students from Wageningen University (2015).
Naturalis: Museum, Natural History Collection and Research Institute. Leidse Kennisdag, Leiden (2015).
