I completed my undergraduate studies in Ecosystem Engineering at the Ikiam
Amazon Regional University, in Ecuador. I participated in research projects at the
interface of ecology and tropical forest biology, and I am interested in many
questions involving biodiversity management and conservation. My research project
focuses on assessing the degree of spread of Caragana arborescens and
the factors that favor its invasiveness in the Central Parkland and the Central
Mixedwood subregions of Alberta.
I completed my BSc in Environmental and Conservation Sciences at the University of Alberta.
Prior to beginning my graduate studies I worked in government and the non-profit sector. I am interested in understanding
the role of soil nutrients and anthropogenic disturbance in habitat invasibility. My research project compares nutrient dynamics
and levels of non-native plant invasion across habitats in the Central Parkland Subregion of Alberta.
I completed my BSc in Biological Sciences with a concentration in Conservation Biology and Ecology at Arizona State University. My research project focuses on the invasiveness of small-sized nonnative annual forbs and their ecological impact on grassland and meadow communities. In my spare time, I enjoy reading, making art, and avoiding getting hit by cars while biking.
I completed my BSc in Biological Sciences and MSc in Ecology and Limnology at the State University of Maringá, Brazil.
My research project focuses on comparing
the levels of alien plant invasion across habitats of the Alberta prairie in order to find similarities among the impacted habitats.
These results will contribute to a solid theoretical framework applicable to conservation efforts and risk assessment across ecosystems.
In my free time, my other interests include outdoor activities, fitness and occasional gaming.

I am studying levels of non-native plant invasion along a latitudinal gradient of native prairie grassland in Alberta, Canada.
Field data will be analyzed to determine the role of climate and anthropogenic disturbance as predictors of invasibility in prairie grassland.
Prior to starting graduate studies, I worked in environmental consulting and government, and I earned my Professional Agrologist (P.Ag.) designation in 2018.
Education: BSc Environmental and Conservation Sciences, University of Alberta, 2014
I completed my MSc in Ecology and Limnology at the State University of Maringá, Brazil.
I am interested in understanding the processes related to aquatic plant invasions providing
answers to questions such as: What are the pathways of introduction of these organisms?
How do aliens affect the native biota? What does make some organisms more invasive than others?
I tackle my research questions through experiments, field sampling, and data compilation
We will be recruiting UofA undergraduate research students for 1-2 BIOL 398/498 and BIOL 399/499 projects in Fall/Winter 2023/2024. Contact Viktoria by May 31, 2023, if you are interested.
Summer 2023 position: We are looking for a UofA undergraduate student to apply for a USRA and join our project on invasive Caragana arborescens invasions.
We have currently no open positions.
Our department is equipped with greenhouses and the University operates field
stations in central southern Alberta. Soil and plant samples can be analyzed in the lab,
and at NRAL and BASL.
Edmonton hosts is home to two herbaria (ALTA at our university and
the PMAEM). The U Alberta Botanical Garden is just 30min away in Devon.
The city lies in a transitional zone between the temporate and boreal zones.
The prairie grasslands (in the south) and the Rocky Mountains (further west) are just 2h away by car.
