[Current research updates]


I am an environmental geologist working with topics related to anthropogenic environmental change and long-term climate dynamics. In particular, my primary research interests are in aquatic ecology and in the use fossil midge (Nematocera) larvae as indicators of past environmental change. In addition to midges, I use diatoms (Bacillariophyta), water fleas (Cladocera), and several macroinvertebrate groups, such as mites (Hydrachnidae, Oribatida), caddisflies (Trichoptera), and mayflies (Ephemeroptera) in paleolimnological downcore and calibration set studies. I am also intrigued by the use of paleoecological data to disentangle and prove ecological theories. Major part of my current research is related to the use of stable isotopic signatures in examining aquatic biogeochemical cycles, food web structure and paleoclimate. In the most recently funded research project, I study microplastics and their ecotoxicological effects in Arctic coastal lake ecosystems. I am also involved in several lake management projects, where I use paleolimnological methods to assess ecological and limnological baseline conditions to set targets for restoration efforts.
