Colleen earned a BS in Geology from California State University, Sacramento, an MS in Soil Chemistry from University of Idaho, and PhD in Biogeochemistry from Stanford University. Colleen is interested in the relationship between geochemistry and organismal health. Outside of work, she spends time with her three rambunctious daughters, dog, and 6 chickens, and sails with her family (minus the dog and chickens) in the beautiful waters surrounding Cape Cod.<\/p>\r\n

Lorelei earned a B.A. in Earth and Planetary Science from Harvard College in 2024, where she specialized in marine microbial organic geochemistry. Lorelei is interested in the production of reactive oxygen species in marine systems; her work in the Hansel Lab focuses on assessing the relationship between hydrogen peroxide and marine organismal health through the development of a deployable ROS sensor. Outside the lab, Lorelei enjoys swimming (in the pool and ocean!), reading, and antiquing.\u00a0<\/p>\r\n

Katherine (Kate) Lane researches marine microbes using chemical, molecular, genetic, and computational tools in Dr. Colleen Hansel’s Lab. She is an NSF-GRFP Fellow and started her PhD in the MIT \/ WHOI Joint Program in 2021. Kate received her M.Sc. degree in Population Biology from UC Davis in Prof. Jonathan Eisen’s Lab, worked as computational staff in Prof. Jill Banfield’s Lab at UC Berkeley, and completed her BA in Biology at Macalester College. Outside of the lab, Kate likes climbing, ceramics, and classical music.

Jenn is broadly interested in trace metal cycling in the environment with particular interest in microbial controls, hydrothermal vents, and trace metal uptake by organisms. When not in the lab or at sea, Jenn enjoys any water based activities, traveling, puzzling, reading, cooking, and spending time with her English Setters.<\/p>\r\n Gemma earned a B.S. in Marine Science and Biology from the University of Miami and a M.S. in Marine Biology from James Cook University. At the University of Miami, her research examined the effect of fragment size on the short-term growth of five Caribbean coral species. During her master’s degree, she interned at the Australian Institute of Marine Science where she used molecular biology techniques and photogrammetry to support coral restoration interventions. In the Hansel Lab, Gemma is studying the use of mineral-enhanced substrates to enhance coral resilience. Outside of work, she enjoys hiking, reading, trying new restaurants, and day tripping around the Cape.<\/p>\r\n <\/p>\r\n Grace received her B.S. in Chemistry from Brandeis University. While at Brandeis University, her research focused on elucidating mechanistic features and structural patterns of the\u00a0Lt<\/i> SAMHD1 enzyme and variants. Joining the Hansel Lab in 2024, Grace is investigating photochemical and mineral driven Mn oxide formation for early Earth and modern Mars applications. In her free time, Grace enjoys trying new coffee shops, biking, and spending time with friends and family.<\/p>\r\n Eric Ryberg (2021-2024); currently Assistant Professor at the University of Connecticut<\/p>\r\n Austin Greene (2023 – 2024); currently Lead Scientist at the Washington State Department of Natural Resources<\/p>\r\n Chadlin Ostrander (2021-2023); currently Assistant Professor at the University of Utah<\/p>\r\n Veronique Oldham (WHOI, 2017-2019); currently Assistant Professor at URI<\/p>\r\n Julia Diaz (WHOI, 2013-2015; Harvard 2011-2012); currently Assistant Professor Scripps Inst Ocean.<\/p>\r\n Tong Zhang (WHOI, 2012-2015); currently Professor at Nankai University<\/p>\r\n Peter Andeer (WHOI, 2012-2014); currently Scientist at Lawrence Berkeley National Lab<\/p>\r\n Yuanzhi Tang (Harvard, 2011-2012); currently Associate Professor at Georgia Tech<\/p>\r\n Victoria Parisi (Harvard, 2010-2011); currently Staff Scientist at Occidental Petroleum Corp<\/p>\r\n Deric Learman (Harvard, 2008-2011); currently Full Professor at Central Michigan University<\/p>\r\n Cara Santelli (Harvard, 2007-2010); currently Associate Professor at Univ. of Minnesota<\/p>\r\n Eileen Ekstrom (Harvard, 2007-2009) ; currently Founder\/Director at Ecosystems Analytics<\/p>\r\n Lina Taenzer (WHOI-MIT JP, 2019-2024); currently postdoc at Woods Hole Oceanographic Institution<\/p>\r\n Erica Herrera (WHOI-MIT Masters, 2020 – 2024)<\/p>\r\n Kalina Grabb (WHOI-MIT JP, 2017-2023); currently postdoc at Ocean Frontier Institute, Dalhousie University<\/p>\r\n Hayley Gadol (MIT, 2015-2021); currently postdoc at Northwestern University<\/p>\r\n Kevin Sutherland (WHOI-MIT JP, 2014-2019); currently postdoc at Harvard University<\/p>\r\n Gabriela Farfan (WHOI-MIT JP, 2013-2018); currently Curator and Scientist at Smithsonian<\/p>\r\n Emily Estes (WHOI-MIT JP, 2011-2017); currently Scientist at IODP<\/p>\r\n Carolyn Zeiner (Harvard PhD, 2010-2015); currently Assistant Professor at St. Thomas University<\/p>\r\n Adiari V\u00e1zquez-Rodr\u00edguez (Harvard PhD, 2008-2014); currently VC Investor at Next47<\/p>\r\n Chris Lentini (Harvard PhD, 2007-2013); currently Vice President of Acquisition, Zazzle<\/p>\r\n Nancy Martinez (Harvard SM, 2008-2010)<\/p>\r\n Lu Sun (Harvard SM, 2008-2010)<\/p>\r\n Seeley McGillis (WHOI SSF, May-August 2024) Natalie Danek (2023-2025); currently graduate student at University of New Hampshire<\/p>\r\n Megan Gonos (2024 – 2025); currently graduate student at Montana State University<\/p>\r\n","protected":false},"excerpt":{"rendered":" The Hansel Lab Team Colleen Hansel Senior Scientist Colleen earned a BS in Geology from California State University, Sacramento, an MS in Soil Chemistry from University of Idaho, and PhD in Biogeochemistry from Stanford University.
