PhD Research - Cruz Ortiz

MS Environmental Engineering Sciences, University of Florida
BS Earth Science — Focus: Environmental Toxicology, University of California Santa Cruz

Cruz’s interests revolve around environmental remediation and developing methods to monitor the transport of environmental contaminants, in particular through soil and water. He has an extensive background in environmental toxicology and numerous experiences designing research projects that target the transport of heavy metals in terrestrial and aquatic environments. His overall experience has made him privy to environmental pollution and keen to finding practical solutions.

At the Bren School of Environmental Science & Management, he designs methods to monitor the transport of agricultural nanofungacides and nanomaterials in soil and leachate. He also helped develop an environmental consulting project that monitored seasonal bioaccumulation fluctuations of heavy metals in California coastal mussels. Both of these experiences have contributed to his expertise in EPA methodologies, environmental sampling and processing, and laboratory analytical methods (ICP-MS).

In his previous research, Cruz looked at the cycling of atmospheric mercury (Hg) and its uptake in terrestrial arthropods (spiders, pill bugs, beetles). At the University of Florida, his master’s training as an Environmental Engineer led him to explore pollution control mechanisms, and the toxicity of Gas Metal Arc Welding fume particles.

Prior to his academic career Cruz was an automotive mechanic for SEARS Auto Center. As a mechanic, Cruz saw first-hand the environmental pollution generated by automotive repair. That experience helped generate his desire to understand how contaminants cycle through the environment.
