July 2021: I spend 4 weeks at WasserCluster Lunz working with a large collaborative group on an in-situ mesocosm experiment (funded by AQUACOSM). This experiment was originally planned for Summer 2020, but was postponed due to COVID-19. The aim of the experiment was to use multiple techniques to assess activity of mixotrophic nano flagellates under modified light and nutrient conditions, which may be representative of future climate change scenarios in FW lakes.
February 2021: I am featured in the Penn State News. Link available here.
Summer 2020: It has been an interesting time to be a new PI. I receive a Commonwealth Campuses Research Collaboration Development Grant that supports collaborative research projects between Penn State Commonwealth Campuses and core multi-user facilities at University Park. I also receive a grant from the Pennsylvania Water Resources Research Center via the USGS 104B program to leverage a growing lake monitoring program (PLEON) to better understand biological drivers of cyanobacteria toxicity.
Unfortunately, I was not able to travel to WasserCluster Lunz (Austria) for our AQUACOSM funded project aimed at the role of environmental variability on grazing by mixotrophic plankton. My colleagues look like they had a great time! Here is a photo taken by Sebastiaan Koppelle, a PhD candidate in the Department of Freshwater and Marine Ecology at University of Amsterdam.
