My passion for both robotics and marine biology have inspired me to pursue a career exploring, researching, and protecting the deep sea. I am an undergraduate student at Cal Poly San Luis Obispo, where I major in Mechanical Engineering and also work as a technician and safety supervisor in the department's machine shops.
I'm thrilled to be spending my summers in my home town of San Diego working in the Deheyn lab at SIO, where my current research is studying communication and biological function of different invertebrates from electromagnetic energy generated by these organisms. I am also testing the function of a novel analytical device called the B.U.M.P. (Benthic Underwater Microscopic PAM). I've previously worked on and continue to support efforts focusing on image analysis and algorithm development to help quantify microplastics/microfiber pollution in the oceans, and the development of robotic systems able to precisely function in high pressure environments like the deep sea. I plan to pursue a Ph.D. in Marine Biology at Scripps after finishing my B.S. at Cal Poly, and ultimately aim to design and build research submarines and underwater ROVs (Remotely Operated Vehicles) to explore the deepest parts of the ocean.

I'm interested in the light propagation in natural photonic structures. I want to know how light goes from the inside to the outside of a bioluminescent organisms. I look at the structures that could influence the way light travels through the animal. This knowledge will help to make light emitting diodes more efficient and therefore more economic in terms of energy consumption.

How do animals influence light with their body parts and what can we learn from it to make lighting less energy consuming?

I am a biology student at the University of La Rochelle in France. I was supposed to do my three-month internship at the Scripps Institution of Oceanography. Unfortunately, public safety considerations related to the Coronavirus (COVID-19) did not allow me to go to San Diego. So I virtually joined the Deheyn lab to work on plastic microbial biodegradation.

I have always been interested in the microbial world as well as the marine world. My research focuses on the definition of biodegradation in general and the mechanism of microbial degradation. This subject is really interesting because plastic pollution is becoming very worrying nowadays and it is also very interesting to discover how bacteria can degrade plastic. It is an honor for me to be able to participate in the research conducted in this renowned laboratory.

As a Visiting Scholar in the Deheyn Lab my research encompasses a twofold approach to the ecotoxicology of Microfibers by addressing this contaminant through the use of bioluminescence as a proxy for toxicity, and methods of microfiber generation from various fabrics in order to understand the different variables that play into their release in the environment, and how this may negatively impact living organisms.

It is my hope that by standardizing these methods for understanding the scope of plastic pollution, will allow for researchers globally to tackle this problem. As well as communicate effectively with the public in order to create a sense of trust and community where we all take responsibility for our choices not only in plastic consumption but in how we treat our environment.

My background lies in Environmental Microbiology, Aero-Microbiology, and Environmental Management. And I am currently studying at the Erhvervsakademi Aarhus & Aarhus University in Denmark working on my senior thesis.

In lab, I work very closely with Mary Ann Hawke on our pollen adhesion project. We are trying to understand the phenomenon of various types of pollen (7 types: olive, pecan, poplar, ragweed, sunflower, dandelion, and kentucky bluegrass) adhesing to various surfaces such as glass, polystyrene, surfasil, etc. We use a flow chamber with water and air at a multitude of speeds (mL/min) to identify the percentage of coverage from start to finish. We are hoping to understand the forces that are happening between the pollen and different surface textures when adhesion occurs. I played water polo for the UCSD Women's Water Polo Team all four years and continue to stay active with yoga and kayaking in the La Jolla Cove. I also enjoy journaling and painting in my spare time.

"Where does the light in the ocean come from?"

A surprisingly large amount of marine animals produce light for various reasons, including camouflage as well as revealing themselves or others. My research focuses on the biochemistry of light production of the parchment tube worm Chaetopterus sp. and on optical properties of the nudibranch Flabellina (Spanish Shawl), the sea slug Navanax, and the blue Traveller's palm seed. In the mucus secreted by Chaetopterus, we found a super fast ferritin that we are now further characterizing.

I obtained my Masters degree in Biochemistry and my PhD in Bio-engineering at the University of Leuven (Belgium), where I first studied a proposed inhibitor of HIV integrase, and later the nonlinear optical properties of fluorescent proteins along with the (nonlinear) optical properties and the behavior of small molecular dyes inside living cells. I started as a postdoctoral researcher here at Scripps Oceanography in 2014.

I am a French student from ENGEES Strasbourg, and I am doing an undergraduate internship in the Deheyn lab from May 2019 to July 2019. I will graduate next year as an engineer in waste treatment. As I have always been passionate about oceans and its wildlife, for my fourth-year internship I wanted to study marine pollution to lock the two subjects: coming to SCRIPPS Oceanography had been the best idea I could have ever thought about!

The objective of my internship is to assess the concentration of microfibers all over the earth. I use samples of seawater, but also of air and sediments. Microfibers are microscopic fibers usually smaller than 5 micrometers (60 to 80 times smaller than a hair diameter!). These microfibers come from our clothes and textiles: as they are not filtered neither by our washing machines nor by wastewater treatment plants, they end up into our rivers and oceans. They are so small that they can be ingested by fish and penetrate cells and tissues!

My research is focused on microfibers that are leaching into the ocean from our clothing. I built and implemented two experiments that are currently running simultaneously. The first experiment is demonstrating different textile degradation processes while exposed to the seafloor environment. The second experiment, observes the same fiber samples within a more controlled environment (within the lab). I take this project very seriously as I am incredibly passionate about spreading awareness to the general public with regard to the variety of ways plastic has and is negatively affecting our natural environment. Especially how very few people realize that a lot of our clothes are made out of plastic, such as polyester and nylon, which have now become the more apparent micro-plastic plaguing our oceans.

I enjoy learning from a variety of countries and cultures. I have lived in Denmark, Australia, Spain and I recently completed my first year at Utrecht University in The Netherlands.

I am an avid explorer, biology-enthusiast, and engineer who is passionate about exploring the oceans. I am working towards completing my doctorate degree in the field of biomimetics and biomechanics at the University of California, San Diego (UCSD), working with Dr. Dimitri Deheyn and Dr. Michael Tolley (Bioinspired Robotics and Design Lab). My research encompasses biomimetics and recently includes understanding spatial distributions of microplastics/microfibers. My research allows me to study biology (ie suction discs of fishes) to inform and better engineer material systems. For part of the year, I also work as a Remotely Operated Vehicle (ROV) pilot on adventures to the deep sea where we sample and learn from the incredible biology and geology of the sea floor.

I received my B.S. from MIT in Biological Engineering, and my M.S. from UCSD in Mechanical and Aerospace Engineering.

I'm studying Marine Biology at UCSD, gaining a scientific background that I intend to apply towards the reformation of business and government practices and policies that are detrimental to marine ecosystems, as well as the invention and implementation of restorative programs. As oceanographer Sylvia Earle (my hero) frequently remarks, “No blue, no green!” My current research in the lab addresses the mechanism which the shrimp species Palaemonetes paludosas uses in order to keep its figure translucent. The methods I find successful in experimenting on the shrimp will then be transferred to studying the same mechanism found in the glass catfish species, Kryptopterus vitreolus.

Southern California has been severely drought-plagued for a decade. Harvesting water from air is an innovative way to alleviate the freshwater crisis. Torrey Pine trees are well known for their ability to harvest moisture. My research is focused on learning its surface structures and properties at a microscopic level and applying the findings to a water harvesting material or device.
I am an upcoming junior in high school and a quirky, curious scientist and engineer. I am a winner in multiple national science fairs, such as Intel ISEF, JSHS, and Broadcom MASTERS, and serve as the captain of my robotics team. Outside of the STEM world, I am a varsity golf player and known as "the pun master" among my friends.

I study how green fluorescence works as a stress indicator in corals and sea anemones in response to ocean acidification conditions. Fluorescent proteins make up roughly 14% of the coral's total protein content but their physiological role has yet to be determined. I worked on correlating the relationship of GFP to antioxidant capability, maintaining intracellular pH, and the task of calcification under ocean acidification conditions.

There are currently no available methods to determine coral reef physiology except by disruptive sampling. However, coral reefs have already been in such a dramatic decline that it would not be beneficial to remove these animals from their environment. This process would quickly deplete the already-declining coral reef coverage. Thus, there is a great demand for an in vitro non-invasive method to determine coral reef health.

Fascinated by color in nature, I was immediately attracted to the amazing research and biomimicry performed at the Deheyn lab. In particular, it is the strong emphasis of research performed on marine biology such as cephalopods, nudibranchs, and corals that intrigued me to join as a volunteer.

A first year undergraduate Materials scientist and engineer (MEng) from Imperial College London, I am currently using my knowledge to further discover mechanical, thermoregulating, and optical properties of various types and compositions of melanin in the local giant keyhole limpet species (Megathura crenulata). Working with technology such as tensile testing, IR-imaging, and oceanographic spectrometers, I have received so many exciting opportunities! I look forward to pursuing a career related to marine biology and biomimicry; Scripps Oceanography is a great place to learn and be inspired!

I am a biology student at the University of La Rochelle in France. In order to validate my degree, I had the opportunity to do my three-month internship at the renowned Scripps Institution of Oceanography. I joined Dr. Deheyn's laboratory in order to work on microfibers. My subject is to analyze the degradation of different textiles under natural conditions. For this reason my subject is divided into two different parts. The first experiment aims to observe the alteration of the different textile coupons over time. While the second experiment quantifies the amount of microfibers detached from textile coupons. This subject is very interesting because it reflects today's problems concerning environmental pollution caused by plastics, microplastics, but also microfibers released in very large quantities as a result of textile washing.

It is therefore an honor for me to participate in environmental research and to work with the Deheyn lab team.

My role in the lab has largely centered around projects to determine the effect of pesticide treatment on coral fluorescence. I hope to contribute to the establishment of new sub-lethal indicators of coral health, which will help future researchers less destructively test coral resilience. I am especially interested in the biomedical and technological applications of such light production and ecotoxicology studies, and determining the role anthropogenic sourced toxicants play in a marine environment.

I am a fourth-year Nanoengineering student at UC San Diego specializing in Bioengineering and minoring in General Biology. In the fall of 2021, I will be continuing my education at UCSD with their Nanoengineering M.S. program studying biomedical nanotechnology. As a volunteer at the Deheyn lab, I help process, image and analyze seawater samples for microfiber detection and characterization. We hope to better understand microfiber generation and degradation in consideration of human and environmental health. I hope to one day work with bioinspired drug delivery systems for improved cancer therapy. I am also an outdoor enthusiast and a proud bookworm!

I am a French undergrad biology major and I am interested in learning about marine biology and especially about bioluminescence. I believe that the ocean offers an incredible source of information to learn about a large diversity of organisms. The Deheyn's lab studies different concepts of marine life to improve our scientific knowledge.

I am working on a project about photoprotein reaction involved in light production. Indeed, the parchment tube worm produces a bioluminescent mucus. Studies show that the mucus light production is highly specific to iron and not shared with other elements. However, we believe that the affinity between iron and the photoprotein prevents a reaction with any other element. My goal is to remove iron using different treatments and add other metals to see if the light production is affected.

I am currently an undergraduate student at UC San Diego majoring in Environmental Systems: Environmental Chemistry and double minoring in Computer Science and Urban Studies. Within the Deheyn lab, I have been studying the toxicity of sunscreen products on brittlestars using bioluminescence as a proxy. As the amount of sunscreen and other UV-filter containing substances increases in the ocean, particularly in coastal waters near tourist beaches, the effects on complex organisms are largely unknown and potentially harmful.

I am currently pursuing my B.S. in Bioengineering at the University of California, San Diego. I have always been fascinated with the idea of mimicking nature and the use of nature's innovation to solve problems we face today. I joined the Deheyn lab at the end of 2016 and I am extremely excited for the opportunity to explore the possibilities of biomimicry. I am currently working with Dr. Jennifer Taylor to characterize barnacle shells and with Dr. Daniel Wangpraseurt observing photosynthesis in coral reef organisms. In both of these projects, I am also excited to explore the possibilities of also implementing 3D printing. I am also on the men's volleyball team at UCSD and enjoy playing basketball when it is not volleyball season.
