Students 

 

Astrid Leitner recently completed her PhD in biological oceanography and previously graduated from the University of California Santa Cruz with a BS in Earth and Planetary Sciences with an Ocean Sciences Concentration and a BS in Marine Biology. In her undergraduate studies she worked on coastal ecology in the kelp forests and the rocky intertidal at her home institution as well as deep sea biology through a submarine canyon project at Hatfield Marine Science Center. At UH manoa she worked on the ABYSSLINE project, developing an ecological baseline for the abyssal ecosystem in the Clarion-Clipperton fracture zone in light of recent mining claims. She is continuing her work on abrupt topographies especially seamount ecosystems.

Past Lab Members

 

Dr. Jeffrey Drazen

 

 

 

Jeff is a professor in the department of Oceanography at University of Hawaii, Manoa. He earned his PhD from Scripps Institution of Oceanography (under Dr. Ken Smith) and he was a postdoctoral fellow at the Monterey Bay Aquarium Research Institute (under Drs. Jim Barry and Bruce Robison). His research interests are the trophic ecology and energetics of fishes in open ocean and deep sea ecosystems. Recently his research has evaluated the use of spatial management strategies for deep water bottomfishes, examined mesoscale variability in micronektonic communities, explored the structure of deep sea and pelagic food webs using stable isotopes and other biomarker techniques, evaluated abyssal fish and scavenger populations in areas that will be mined for metal resources, and examined the structure and function of trench communities including the Mariana Trench Marine National Monument. Much of his research has been in collaboration with NMFS scientists and he is a senior fellow of the Joint Institute for Marine and Atmospheric Research.

Liz Miller

 

 

Jessie Perelman is working towards a PhD in biological oceanography. She graduated from the University of Southern California in 2016 with a B.S. in biological sciences, and spent a year in Brisbane, Australia where she studied the feeding dynamics of Indo-Pacific wahoo. After graduation, she worked at the Woods Hole Oceanographic Institution focusing on acoustic behaviors in marine invertebrates and coral reef soundscape ecology. In the oceanography program at UH, Jessie is studying midwater ecology and focusing on the potential impacts of deep-sea polymetallic nodule mining on deep pelagic ecosystems.

Andrew Tokuda

 

 

Andrew is an undergraduate in the Global Environmental Science program. Since his childhood years, Andrew had a constant passion for the ocean and its inhabitants, which drove him to take part in a variety of outreach programs pertaining to the sea, and two international exchange programs involving Japanese longline fishing vessels during his junior and senior year in high school. His research in the lab involves an isotopic analysis of hadal food webs. By exploring one of the most mysterious habitats on the planet, he hopes to foster his research interests in deep-sea fisheries and their role in today's internationally complex modern society.

Sonia Romero

 

 

 

 

Jesse Black

 

 

 

Sonia Romero's research centers on the use of stable isotope analysis to elucidate the trophic ecology of deep-sea food webs from zooplankton to top predators. She earned her PhD in 2017 from the University of Oviedo (Spain) where she investigated trophic ecology in the Avilés Submarine Canyon ecosystem as well as the pathways of particulate organic matter within the food web. At UH Manoa, Sonia is examining the importance of suspended particles in food resources across pelagic food webs of contrasting ecosystems using amino acid compound-specific nitrogen isotope measurements.

Jesse Black is a PhD student in biological oceanography. He graduated from the University of Illinois at Urbana-Champaign in 2016 with a B.S. in biology. As an undergraduate research assistant, Jesse studied the microbial ecology of hot springs in Yellowstone National Park. After graduating, he worked as a research technician at the University of Chicago for a year studying photosynthetic microbes and their viruses in the Great Lakes. Jesse's research at UH is focused on determining the relative influence of environmental drivers on the growth of deep-sea fish.

Liz Miller is a PhD student in biological oceanography. Originally from Seattle, she graduated from Bard College where she studied grassland plant ecology and soil microbiology. At UH, Liz uses stable isotope chemistry to study food webs in the deep sea off of Hawai'i and California. She is interested in how microbes influence food supply and trophic interactions in the abyssal realm.
