Role as Faculty

Teaching brings Lorena a profound satisfaction and experience. Her goal is to help students have a basis for solving complex problems in chemistry, and to teach critical thinking. In chemistry courses, laboratories are essentials; however, many students feel afraid to experiment. In her lab courses, Lorena always encourages students to learn from their mistakes and feel confident experimenting.

Research Interests

Environmental chemistry pollution. Emerging micropollutant as synthetic microplastics debris in the oceans and the Great Lakes environments. Her research included extraction, identification, and quantification of persistent organic pollutants, POPs, in sediments, tissues, water and plastic debris. Lorena found several POPs adsorbed on plastic debris such as PCBs, PAHs, and organochlorinated pesticides that may have negative effect on hormones of the organisms that are ingesting these plastic particles. To understand this effect, Lorena is studying estrogen receptors using computer models and the Quantum Chemical Theory to calculate the interaction between POPs and the hormone receptors. Currently, she is working on the analysis of microplastics collected from the Great Lakes.

Research Opportunities for Students

• Microplastic debris pollution in freshwaters and oceans
• Phthalates in water from plastic bottles
• Caffeine in Lake Superior waters
• Environmental chemistry pollution in freshwater system (The Great Lakes).
• Plastic debris in the Great Lakes, specifically its role in accumulating and transporting POPs to aquatic organisms.
• Analysis of plastic fibers in air and plastic pellets from different countries.
• Environmental contamination in seawater by Persistent Organic Pollutants (polychlorinated biphenyls, PBCs; polybrominated biphenyls and polybromated Diphenyl ethers, PBBs & PBDEs; organochlorine pesticides, DDT, BHC, aldrin, etc), in sediments, tissues, and plastic samples.
• Environmental contamination in oceanic sediments by trace metal.
• Emerging contaminants in the Lake Superior water.
