Kirstin Meyer-Kaiser
Marine biologist 

Most of the ocean floor is blanketed by soft sediments, so hard-bottom habitats are usually isolated and island-like. Any solid object - be it a reef, a lone rock, or a shipwreck - will inevitably be colonized, and these substrata provide habitats for diverse and abundant communities of sponges, anemones, crabs, mussels, and fish. As a benthic ecologist, I study the colonization and connectivity of island-like hard-bottom habitats.

My research focuses on the early life-history stages of invertebrates, including larval dispersal and recruitment. The larval phase is the only opportunity for sessile organisms to spread to or colonize new environments, but larvae and new recruits suffer high mortality because of environmental stress and predation. I seek to understand how these restrictions affect the connectivity of populations and what factors might allow some larvae to disperse farther than others. I work at all depths from the intertidal to the deep sea and I have ongoing projects at polar, temperate, and tropical latitudes.

In order to collect samples and conduct experiments, I embark on frequent expeditions to the field. I use SCUBA and small boats to reach near-shore habitats and participate in oceanographic expeditions on larger research ships to sample off-shore or deep-sea habitats with remotely operated vehicles. Much of my work involves collection of high-resolution imagery - either video or photos - from the seafloor, and so image analysis is a staple of my research. I travel frequently, both domestically and internationally.

Currently, I am an Assistant Scientist at Woods Hole Oceanographic Institution (WHOI).

Calvin Mires
Maritime archaeologist

Dr. Calvin Mires has almost 20 years of experience in maritime archaeology and underwater cultural heritage. He is a Research Associate III at Woods Hole Oceanographic Institution. He has led and worked on more than 30 maritime archaeology projects around the world, including Greek and Roman shipwrecks and harbors, Sweden's iconic warship Vasa, Confederate Blockade Runners in North and South Carolina, ship graveyards in Bermuda, and various sites in the Caribbean Sea, Pacific Ocean, and the Great Lakes. He is co-founder and instructor of SEAMAHP, a training program that leverages the concept of a ship's life-cycle to provide hands-on experiential learning to the public in maritime archaeology. Since 2015, he has co-directed the only maritime archaeology field schools in Massachusetts with cooperation of the Massachusetts Board of Underwater Archaeological Resources, the Trustees of Reservations, and the National Park Service, and has run maritime archaeological summer programs for middle and high school students. He is a Senior Tutor for the Nautical Archaeology Society for the New England region, a group that provides maritime archaeological training for the public. He has received grants from the National Park Service Maritime Heritage Program and the National Oceanic and Atmospheric Administration and has published in The International Journal of Nautical ArchaeologyThe Society for Historical Archaeology, and Bermuda Maritimes. He is currently involved in several projects in Massachusetts, including archaeological investigation of the 1626 Sparrow Hawk and deep-sea research on shipwrecks in Stellwagen Bank National Marine Sanctuary.

Kharis Schrage
PhD student in the MIT-WHOI Joint Program

My name is Kharis, and I am a PhD student in the MIT-WHOI Joint Program. I am from Alexandria, VA and went to William and Mary for my undergraduate (2017), where I studied the intertidal ecology and larval development of hemichordate worms in Dr. Jon Allen's lab. I have spent the past few years in the field working as a technician on a number of projects, from sturgeon population dynamics in the southeast U.S. to zooplankton ecology and pelagic trophic dynamics in Antarctica. These passions for invertebrate ecology, larval development, and polar science came together and led me to the Meyer-Kaiser lab, where I am studying the benthic ecology of invertebrates and their meroplanktonic larval stages in the Arctic. I use both oceanographic instruments as well as SCUBA to study and collect these organisms. I am still working out the specifics of my project, but I am very excited to be at this stage! Beyond my science, my favorite things still involve adventures and water - diving, fishing, traveling, exploring new places (and fudge!). I can be reached at

Kimberly Nuñez
Summer Student Fellow

Hello! My name is Kimberly and I am from Brooklyn, NY. Currently, I am a Junior at CUNY Macaulay Honors College at John Jay College of Criminal Justice where I major in Cell and Molecular Biology with a double minor in Chemistry and Environmental Justice. I am the Lead Biology Tutor at John Jay’s Math and Science Resource and conduct research in Dr. Anthony Carpi’s lab. My current project focuses on determining how microorganisms play a role in soil mercury emissions through methods of stimulation and suppression. My marine biology research interests lie in those that can inform environmental policies, particularly megafauna conservation. This includes studying the anthropogenic and climate-driven effects on population and community dynamics, migration patterns, predation habits, communication, and behavior. In the Meyer-Kaiser lab, I will be analyzing potential drivers of change to observe how they affect benthic communities in the Fram Strait. During my free time, I enjoy reading, spending time with my friends and family, and catching up on my favorite YouTubers or shows. 

Golden Doodle puppy
Kraken comes to the lab with Kirstin a few days a week. His research interests include chew toys, environmental smells, and treats made from animal protein. His past accomplishments include Sit and Come. Kraken's current research project is entitled "Investigations in misbehavior: methods for optimizing treat output in a Homo sapiens household."
