Max is a chemical oceanographer and analytical chemist who joined Moss Landing Marine Laboratories in the summer of 2018. His research is primarily focused on the chemical, physical and biological processes that impact the distribution of bioactive trace metals (e.g., Fe, Zn, Mn, Cu), tracers (e.g., Al) and nutrients (N, P, Si) in coastal and open-ocean regimes. In addition, he has a special interest in developing and applying novel in situ microfluidic instrumentation to improve the spatial and temporal resolution of chemical observations in the marine environment.
Max’s research encompasses field studies in order to map the distribution of trace metals and quantify their inputs and removal rates in the marine environment, as well as the development and application of automated microfluidic analyzers for nutrients and trace metals. Upcoming research projects in the Chemical Oceanography lab include but are not limited to: (1) a research expedition (2018-1019) to study the seasonality of Fe and Zn concentrations and primary productivity in the vicinity of the Marquesas archipelago (French Polynesia), (2) the development of novel automated microfluidic methods for trace metals (Fe, Al), and (3) instrumenting MLML’s Seawater Intake Monitoring Station with nutrient analyzers (N, P, Si) to study high-resolution nutrient dynamics in relation to phytoplankton productivity and diversity in Monterey Bay.
Max obtained his Ph.D. in Oceanography at the University of Hawai‘i at Mānoa in 2014, where he studied the distributions of dissolved Fe and Al in the Indian Ocean and pioneered the application of micro Sequential Injection to the analysis of trace metals at sub-nanomolar levels in seawater. He later joined the University of Southampton National Oceanography Center as a postdoctoral research fellow, where he contributed to the development and oceanographic validation of in situ Lab-On-Chip phosphate analyzers.
