Today we say goodbye to Ichiko Sugiyama, who wraps up her time with the NIRVANA Lab. Ichiko joined us in late 2022 to study microbial metal demand in the Eastern Tropical Pacific, working jointly with Mak Saito and myself. She sailed on the AT50-10 CliOMZ expedition, where she conducted an impressive number of isotope tracer…

I’m delighted to share that, earlier today, the President and Director, Peter de Menocal, notified me that my application for tenure at the Woods Hole Oceanographic Institution has been granted. This is a big personal milestone, and I want to take a moment to say how deeply grateful I am; for the guidance of my…

It is my great pleasure to welcome Jordyn Wemhoner to the NIRVANA Labs. Jordyn joins as a graduate student in the MIT–WHOI Joint Program, having earned her Bachelor’s degree in Chemistry from the New Mexico Institute of Mining and Technology. She previously interned for several summers at Sandia National Laboratories and arrives in Woods Hole…

We are thrilled to welcome Evren Arif to the NIRVANA Labs as a Summer Student Fellow for 2024. Evren is currently a junior at Tufts University, where he studies Environmental Geology and Applied Mathematics. He has a keen interest in the intersection of mathematical modeling and biogeochemical processes. Evren’s project will build upon a recent…

I’m happy to welcome Pierre Cadeau, Postdoctoral Fellow, to the NIRVANA Labs! Pierre plans to investigate how non-traditional stable isotope systems, such as cadmium and nickel, can be used to trace Earth’s biogeochemical evolution. His project is supported by a Marie Skłodowska-Curie Actions Postdoctoral Fellowship and is being conducted in collaboration with Oliver Rouxel (Ifremer).…

I’m pleased to welcome Georgi Laukert, Postdoctoral Fellow, to NIRVANA! Georgi plans to study how changing sea ice affects macro- and micronutrient cycling in the Arctic (Project ICEotopes). He project is being conducted in collaboration with Tristan Horner and Kate Hendry (British Antarctic Survey) and is supported by a Marie Skłodowska-Curie Actions Postdoctoral Fellowship. Welcome…

Congratulations to Dr. Logan Tegler, who successfully defended her Ph.D. thesis today! Logan’s thesis is titled: “From the atmosphere to the abyss: Tracing organic carbon deposition, cadmium isotopes, and iron cycling using marine sediments,” and is available to download from DSpace@MIT. Well done Logan, incredible work!

I’m pleased to welcome Ichiko Sugiyama, Postdoctoral Investigator, to NIRVANA! Ichiko will be using iron isotopes to quantify microbial metal demand in the Eastern Tropical Pacific. She is working jointly with Mak Saito and Tristan Horner on a project supported by the Ocean & Climate Innovation Accelerator consortium. Welcome Ichiko! Check out: Ichiko’s Twitter (@FerrousChiko),…

We are pleased to welcome Margot Debyser, Postdoctoral Investigator, to the NIRVANA Labs! Margot will be leading lab efforts to constrain the cycling of radium and barium isotopes along the US GEOTRACES GP17 transect with Matt Charette and Tristan Horner.
