Dr. Kulacki specializes in aquatic ecology and ecotoxicology. He has 10 years of experience in studying the effects of anthropogenic stressors on aquatic organisms and ecosystems. Dr. Kulacki is familiar with the risks associated with numerous environmental pollutants, including biological, chemical, and physical stressors, and with the various methods available to evaluate their effects. He has performed standard versions of many aquatic toxicological bioassays, and has also modified existing protocols to provide additional important ecological information. In addition to laboratory work, Dr. Kulacki has experience in field-based analysis of the environmental quality of lakes and streams.

Dr. Kulacki’s doctoral research investigated the effects of room-temperature ionic liquids—an emerging class of industrial solvents—on freshwater primary producers and consumers. His post-doctoral work focused on the effects of engineered nanoparticles on benthic and pelagic primary producers and consumers, and on the relative effects of anthropogenic stressors, including eutrophication, biodiversity loss, and herbicides, on the structure and function of stream communities. He has worked effectively on multidisciplinary teams that included chemical engineers, mathematical modelers, microbial ecologists, and watershed planners.

Project Experience

Designed and oversaw project that developed rankings for the effects of seven different chemical, biological, and physical stressors on stream structure and function, using 100+ laboratory mesocosms.

Investigated the mechanisms underlying the toxic effects of titanium dioxide nanoparticles (n TiO2) to freshwater phytoplankton. Examined algal physiology, competition with bacteria, and interactions with UV light and the effects of n-TiO2 on algal chlorophyll content.

Studied fate and effects of titanium dioxide nanoparticles in artificial stream mesocosms, and the relationships between concentrations of n-TiO2 in algal biofilms, algal biomass, and species diversity.

In collaboration with other scientists, reviewed the effects of room-temperature ionic liquids on aquatic organisms and published an invited paper on the topic.

Used standard acute toxicity tests to determine the toxicity of several room-temperature ionic liquids to freshwater algae, and examined the role of cell wall structure in determining toxicity.
