Research Experience

Main field research

2014: Gabon. Research on barcoding of moth communities in Lopé National Park. ECOTROP field class. 2 weeks.

Since 2016: Cameroon. Research on diversity of Lepidoptera along an elevational gradient of Mount Cameroon; research on the influence of forest remnants characteristics on moth communities in a fragmented landscape of the Bamenda Highlands. 3 expeditions, 5 months together. Co-leader of two expeditions.

Since 2016: Czechia. Collecting data on pollinator ecology in fragmented wet meadow landscapes (Železné hory) and along an elevational gradient (Krkonoše), on diversity of moths in previously burnt forests (České Švýcarsko), and on biodiversity of several groups of arthropods along a gradient of disturbance intensity (Brdy Mts.). Several short field trips, 2,5 months together.

2017: Zimbabwe. Research on diversity of Lepidoptera along an environmental productivity gradient. 2 weeks.

2018: Madagascar. Survey of Lepidoptera in the Ranomafana National Park. 1 week.

Since 2018: Republic of South Africa, Kruger NP – research on dynamics of biodiversity in African savannah (field technician for entomological parts), 4 expeditions, 3 months together. Leader of one expedition. 

Study stays

Since 2016: Poland. Zoological Museum of the Jagiellonian University, Krakow. Sorting and identification of moths; close collaboration with the team of Dr. Tomasz Pyrcz and Dr. Rafał Garlacz. 8 visits, 4 months together.

Since 2021: Germany. Bavarian State Collection of Zoology, Munich. Sorting and identification of moths (Geometridae); close collaboration with the team of Dr. Axel Hausmann. 2 visits, 2 weeks together.

Research grants

2020: Travel Grant Programme of the Biology Centre, Czech Academy of Science: attendance at the 18th Savanna Science Network Meeting, 2020, Skukuza, South Africa.
