Dimitri Deheyn : Associate Research Scientist and Lecturer

Dimitri Deheyn

Associate Research Scientist and Lecturer

Dr. Dimitri Deheyn is a Research Scientist at the Marine Biology Research Division of Scripps Institution of Oceanography, University of California San Diego. He leads a cross-disciplinary research program rooted in biomimicry—the science of learning from nature to develop sustainable materials, biochemical processes, and innovations that promote circularity across industrial and societal systems. His work connects fundamental biological research with real-world applications, often in collaboration with industry, through his BEST Initiative (Biomimicry for Emerging Science and Technology), which he founded to support industry-driven sustainability solutions.

Dr. Deheyn’s scientific interests span a wide spectrum, from biophotonics (bioluminescence, fluorescence, and structural coloration) and bioadhesion/anti-biofouling, to UV protection and unusual biomaterials with potential for biotechnological, biomedical, and packaging applications. He studies the biological mechanisms behind these traits to develop biomimetic strategies for a more sustainable future.

A central and growing focus of his research is the ecotoxicology of emerging pollutants, especially plastics and textile microfibers, including their chemical additives. Dr. Deheyn investigates microfiber sources, degradation potential, distribution mechanisms, and impacts on ecosystem and public health, using samples collected globally—from polar to tropical regions, high alpine environments, to the deep sea, and from air, snow, rain, and organisms across Africa, Europe, and the United States. Dr. Deheyn sustains such research by involving a network of citizen scientists, from explorers and nature lovers to high school students.

In recent projects, he has applied biological light—such as fluorescence and bioluminescence—as biosensors to assess the toxicity of micropollutants, offering a novel perspective on contaminant impacts. His research not only addresses environmental pollution but also supports the development of circular fashion systems.

Born and raised in Africa and South America, Dr. Deheyn earned his Ph.D. at the Free-Thinking University of Brussels (ULB), Belgium, where he started his academic career in the late 1990s. His global upbringing and scientific journey inform a worldwide view of environmental challenges—particularly climate change and plastic pollution—and drive his mission to understand and protect ecosystems and their services as foundations for a healthy and sustainable future.

PhD Student

I'm a Marine Biology PhD student, joining the Deheyn Lab in autumn 2020. I'm an evolutionary and community ecologist with an experience/research background in herpetological conservation, and in species and community responses to anthropogenic change. I completed my Bachelor's degree at Hartwick College in New York, my home-state, and my Master's degree at Virginia Commonwealth University.

I am interested in studying biofluorescence from the proximate (what biological compounds and structures fluoresce, and how do they do it?), to the medial (what organisms biofluoresce, and in what ways is biofluorescence meaningful to organisms that do it, or to sympatric organisms; what does biofluorescence do?), to the ultimate (what behavioral and environmental needs and circumstances select for the evolution of biofluorescence?).

Avery Dougherty : Staff Research Associate

Staff Research Associate

I’m a Staff Research Associate in the Deheyn Lab, where I’ve been since 2022, and a La Jolla native who has dreamed of working at Scripps Institution of Oceanography since childhood. I graduated from the University of Colorado at Boulder in 2022 with a degree in Ecology and Evolutionary Biology.

My research focuses on microplastic and microfiber pollution — I collect and analyze samples from air, water, snow, marine life like whales and oarfish, and even human tissues. Through this work, I’m building a growing database that tracks and quantifies microplastic pollution across environments and species, helping us better understand patterns of contamination and exposure.  I aim to help develop practical, science-based solutions and encourage everyday changes that reduce plastic impact. Outside of the lab, I enjoy skiing, yoga, and cooking.

Graduate Student

I am a graduate student in Chemistry at ENS Paris-Saclay, currently in the first year of my Master's program, after completing a Bachelor's degree in Chemistry. I am spending four months at the Deheyn Lab, where I am investigating the effects of UV exposure on textile particles. My research focuses on the process of weathering and how UV radiation alters the properties of different textiles, including polyester, cotton, and lyocell, as well as various fabric colors. In addition to characterizing textile degradation, I am also exploring the potential toxicity of these altered particles on marine organisms, such as bacteria, kelp, and corals. This research combines environmental chemistry and material science to better understand the environmental impact of synthetic fibers and their role in marine pollution.

My name is Brooks and I'm an undergrad at Oregon State University studying marine biology. In the lab, I work on atmospheric water collection using biomimicry and am beginning a project exploring the relationship between microplastics in our ecosystems and tourism. Outside the lab, I enjoy scuba diving, skiing, kayaking, and keeping both freshwater and saltwater aquariums.

I assist in studying the prevalence and effort of the microplastics and fibers in the world around us. I am hopeful the work I do will help deepen our understanding of the effect that microplastics can have on living organisms and incite meaningful change. Outside of the lab, I enjoy exploring the beautiful world we live in!

PhD Student

I’m Valeria Longhi, a PhD student at the Politecnico di Torino in Italy and a visiting scholar at Hubbs Hall at SIO. When I’m not diving into the world of marine ecosystems, you’ll find me hiking through mountains, wandering in forests, or enjoying good food around the world. But don’t worry, I’m still all about the sea – my research focuses on using geomatics to monitor Mediterranean ecosystems, especially Posidonia Oceanica. At my hometown university, we use advanced techniques like underwater hyperspectral imaging to capture details beyond visible light. Here at SIO, I am studying the spectral response of Zostera marina in controlled environments to see how it reacts to different light and temperature conditions.

I am an undergraduate student at the University of Pennsylvania looking to major in Earth and Environmental Science, with a particular interest in the impact of plastic on our oceans. In the lab I focus on measuring microplastic levels by filtering water samples from sites in the San Diego area and around the world. In my free time I enjoy beach volleyball, yoga, music, and photography!

My name is Dylan. I am a senior at Torrey Pines High School. I enjoy working on any project related to the environment and how we can improve it as well as finding more ways to coexist with it. I particularly enjoy studying biomimicry and the ways we can influence our world from solutions found in nature. Outside of the lab I really enjoy rock climbing with friends and playing soccer.

My name is Giulia Galli, and I am an Italian student with a passion for physics and mathematics. I am curious, positive, and deeply enjoy reading and learning. Thanks to MicroMar Global, I had the incredible opportunity to volunteer in Dr. Dimitri Deheyn’s lab at the Scripps Institution of Oceanography. During this enriching experience, I learned how to analyze water, air,  snow and fish filters in order to count the amount of microplastics and microfibers in them. Together with a fellow student, we  conducted our own experiment on the degradation of different types of textiles. Under the expert guidance of Dr. Deheyn and his wonderful lab team observed the swelling of woven materials in various salinity levels, captured images using a SEM microscope, and began analyzing our samples. This experience was not only scientifically rewarding but was also a chance of personal growth. As a 17-year-old taking my first steps into the world of research, I felt welcomed and inspired by Dr. Deheyn and his team.

I’m Ludovica Rocca and I’m in the last year of high school in Italy. I worked in the Deheyn Lab for two months during the summer of 2024, thanks to a school project called Micromar Global that has a specific focus on microplastics and microfibres and how they pollute the environment. In the Deheyn Lab, I researched microplastics and microfibres in samples of water, air, fish and soil. I also thoroughly researched how different textiles degrade in various salinities of water.
