Principal Investigator

I’m a Professor of Biological Oceanography with a broad interest in mechanisms controlling diversity, function and resilience in marine biota. My lab studies these mechanisms through molecular, optical, physiological and biogeochemical approaches. We are interested in how environmental change controls the composition of planktonic populations and how climate-driven processes such as ocean acidification and warming impact the physiology of phytoplankton. 

Postdoctoral Researchers

My primary research interest is to improve our understanding of how anthropogenic activities modify marine biogeochemistry, the consequences for marine ecosystems and the proposal of prevention and recovery measures. I am particularly interested in investigating how climate change modifies marine chemistry and the impact of ocean acidification on marine biogeochemical cycles and microorganisms.

Graduate Students

My research interests are in characterizing marine microbial community structure and diversity with an emphasis on the eukaryotes for the time being. My primary focus is linking optical, chemotaxonomic, and molecular approaches for this purpose, with the hope of developing novel methods for the remote sensing of microbial community structure.

Though I have many research interests, I’m primarily interested in phytoplankton contributions to biogeochemical cycles and how they are responding to anthropogenic ocean acidification. I’m especially interested in conducting research in polar and subpolar seas, which serve as a
bellwether for global ocean acidification.

I am broadly interested in how anthropogenic activities influence marine systems and, in particular, phytoplankton communities. As a PhD student in the Iglesias-Rodriguez lab, my work includes projects investigating the impacts of oil exposure on phytoplankton physiology, how ash deposition in the marine environment alters phytoplankton physiology and community composition, and exploring coccolithophore blooms in the Eastern Bering Sea. I use a diversity of tools such as flow cytometry, microscopy, and omics to gain a better understanding of phytoplankton in both the field and laboratory experiments.

My dissertation explores the impacts of ocean acidification and hypoxia on the health and biology of carbonate-producing marine organisms (calcifiers) in California marine systems. Through the lens of calcifiers/calcification, I examine how human actions (directly and indirectly) influence broader potential patterns of change, stability, vulnerability, and resilience in these systems over time and with a mind towards California’s future ocean conditions. My work implements an interdisciplinary, mixed-method approach combining laboratory experimentation with historical and contemporary field observations and datasets. In addition to Dr. Debora Iglesias-Rodriguez (Biological Oceanography), I am also advised on environmental history and historical ecology by Dr. Jennifer Martin.

Research scientist / Lab Manager

I am a biological oceanographer, and mainly interested in the physiological and ecological properties of individual phytoplankton taxa in their shared environment and the anthropogenic impacts on the coastal ecosystem. I am working in Dr. Iglesias-Rodriguez Lab as an Assistant Specialist, organizing general lab environment, involving in several research projects and maintaining the BD Influx (flow cytometry).


Postdoctoral Researchers

Paul Matson

I am a marine scientist that uses oceanographic and ecological approaches to explore the effects of environmental drivers on marine organisms. Here in the Iglesias-Rodriguez lab, I am investigating how species diversity and morphotypic variation in coccolithophores may influence the biogeochemical cycling through inorganic carbon production. 

Undergraduate Students

Jessica Bullington

My research interests lie in the biogeochemical and ecological importance of marine phytoplankton.  Using probable climate change stressors, I am exploring the physiological effects of a changing environment.

Cristian Cabrera

I am currently working on how phytoplankton populations were affected by ash deposition from the Thomas fire which occurred in December 2017.

Tim Lamour

I am currently interested in how anthropogenic stressors, particularly ocean acidification and global sea temperature rise, will affect phytoplankton in the future. 

Evan McCormack

I am currently interested in how anthropogenic stressors affect ocean water chemistry, and how these factors play a role in the marine microbial community.

Reina Myers

Reina Myers

I am currently working with coccolithophores and studying their physiological adaptations to changes in gaseous concentrations in water.

Jasmine Prat

My research interests include marine biogeochemical cycles, marine ecosystems, and interactions between the two.  In particular I am interested in how these systems will be impacted by environmental changes.  I am currently working with coccolithophores on a project investigating connections between nutrient content and calcification. 

Avery Pullman

My research interests are based on how anthropogenic stressors are affecting marine systems. Particularly, I am intrigued by ocean acidification and its impact on phytoplankton and other marine organisms. 

Adriana Ramirez Negron

My research interests are in understanding how climate-induced changes, particularly ocean acidification and other changes in the chemical composition of marine ecosystems, affect the phytoplankton population and other marine organisms.

Technical Staff

Elisa Wallner Halewood

I am a microbial oceanographer, with a strong interest in the role microbes play in biogeochemical cycling of carbon in the marine environment.  I am working with the Iglesias-Rodriguez Lab as an Assistant Specialist, helping assess inorganic carbon chemistry and assist in analysis of coccolithophore populations through flow cytometry.
