While in the Deheyn lab I was earning my B.S. and M.S. in Marine Biology at the University of California, San Diego. I was working on completing a short thesis for the Scripps Undergraduate Honors Program. The project is based on isolating the photoproteins in a species of bioluminescent brittle star, Ophiopsila californica. Upon successful extraction and purification, we will then work on characterizing and identifying the sequence of the photoprotein. I was a member of the UCSD women’s basketball team for three years and I enjoy SUCBA diving and snorkeling in my free time.

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 honored to be working in the Deheyn Lab during my Master of Advanced Studies program in the Center for Marine Biodiversity and Conservation at SIO. Even through my upbringing in the desert of New Mexico I have always been intrigued with ocean, especially by the production of light by marine organisms. I am currently researching the neurotoxic effects of Polybrominated Diphenyl Ethers (PBDEs) on a bioluminescent species of Brittle Star, Amphipholis squamata.

My interests are to learn more about the implications of contaminant loads that we are chronically exposed to by studying bioluminescence as an indicator of health. Through analyzing the effects of these emerging pollutants on the health of benthic marine organisms we can provide more information about their persistent effects the health of our bodies and environments. I hope to continue research that will allow the communication of science to the public regarding the effects of environmental health on our world at large.

My name is Allison Delgado and I have been a member of the Dehyn Lab for about a year now. I just finished my undergraduate degree at UCSD in Environmental Biology and Earth Science. 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.

I am an undergraduate student from France and I’m currently doing an internship in the Deheyn’s lab to complete my formation in biology. I have always been fascinated by the ocean, its living organisms and the mystery that still remains about it. I decided to work on bioadhesion and especially on the adhesion of the particles responsible for marine fungi’s reproduction, the spores. Our goal is to understand the link between the type of surface the fungi attach to, and the ultrastructure of spores, in order to understand and then avoid the adhesion of these organisms on boats, maritime platforms or fabrics.

For the past year at the Deheyn lab, I have spent the majority of my time understanding the biochemical properties exhibited by the Chaetopterus variopedatus. Not only does this species exhibit fascinating luminescent properties, but it also has the ability to transform a viscous ‘slime’ into a highly ordered three dimensional solid structure. Once created, this structure becomes its cozy abode. My research focuses on this transformation.

My background lies in Biochemistry and Cell Biology with an added emphasis in Marine Sciences. The bountiful discoveries made about the ocean continue to amaze me every day, and I am very thankful to be able to contribute by working in the Deheyn lab. I have always loved the ocean and I aspire to put my skills that I have acquired in this lab to good use in my future career.

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!

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.

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.

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.
