Après 13 ans de recherche en biologie-environnement en laboratoire et d'enseignement dans des établissements d'enseignement supérieur en France et en Asie, j'ai pris la décision de développer un partenariat d'affaire respectant mes compétences et mes valeurs éthiques en 2016. Ce partenariat implique un laboratoire privé en R&D et plusieurs partenaires d'affaires internationaux aux compétences complémentaires pour promouvoir l'innovation en nutrition, génétique de l'anti-âge et soin de peau. Les produits issus de ces recherches sont des soins de haute qualité disponibles pour tous les particuliers ou professionnels dans 50 pays (mon site internet /FR-EN). Au travers de ce projet, j'aide aussi à combattre la malnutrition infantile au travers de Nourish the Children. En plus de cette activité, j'enseigne des matières scientifiques (SVT, EST, etc...) dans des établissements d'enseignement secondaire, je m'occupe d'un groupe de scoutisme (EDLN) et je prends soin de mes 2 magnifiques filles.
J'ai fait de la recherche et enseigné à l'Université de Montpellier / MarBEC à Montpellier (France) et à l'Université de Savoie / CARRTEL au Bourget du Lac (France) après avoir complété un projet de recherche post-doctoral à l'Université de la Préfecture de Shiga (Japon) inclus dans un projet francais Bio-Asia Fascicle avec plusieurs partnaires en Europe et Asie.
Je suis doublement diplômée de l'Université Lille 1 (France) et de la National Taiwan Ocean University (Taiwan) en 2010 après 4 ans d'un programme de doctorat entre le laboratoire LOG (France) et l'Institut de Biologie Marine (Taiwan).
Si vous souhaitez en savoir plus à propos de mon parcours, je vous revois à mon CV and mes publications de 2005 à 2020.

After 13-years of biology and environmental researches as well as teaching in public academic laboratories in France and Asia, I decided in 2016 to develop a business partnership respecting my skills and my ethical values. This partnership involves a private R&D laboratory and several international business partners having complementary skills to promote the innovation in nutrition, genetics of anti-aging and skin care. The products of this research are high-quality care products, available to all the private individuals in need around the world (hereafter my website /FR-EN). This activity involves a humanitarian project reducing child malnutrition (Nourish the Children). Additionally to my business activities, I teach biology in junior high school, animate a scouting group (EDLN) and take care of my 2 wonderful daughters.
I did research and teaching at the University of Montpellier / MarBEC lab at Montpellier (France) and at the University of Savoie / CARRTEL lab at Le Bourget (France) after I completed a post-doctoral research at the University of Shiga Prefecture (Japan) included in the French Bio-Asia project Fascicle involving several partners in Europe and Asia.
I graduated from both the University of Lille 1 (France) and the National Taiwan Ocean University (Taiwan) in 2010 after a 4-year dual PhD program between the LOG lab (France) and the Institute of Marine Biology (Taiwan).

What are copepods ?
(by D. Beyrend)
Copepods are crustaceans and probably the most numerous multi-cellular organisms on Earth (Lee et al., 2005).
They are the biggest biomass in the oceans and so called “the insects of the sea” (Dürbaum and Künnemann, 2000; Schminke, 2007).
They have been able to colonize all aquatic ecosystems from hypersaline, marine to continental freshwater bodies, under all latitudes from polar to tropical regions and have been able to colonized even hot springs waters.
They can be found from the surface to the deep sea bottom close to hydrothermal systems (Ivanenko and Defaye, 2004).
Some copepods are ecto- or endo-parasites having a wide range of hosts from sponges to vertebrates; they exhibit a wide variety of forms without common morphological traits making difficult the taxonomy for the whole group.

How to collect copepods in the field ?
There are several methods for sampling the plankton.
The choice of a method depends on the characteristics of the water system (open marine water, estuaries, lake, etc) the water characteristics (turbidity, depth, density of algae, etc.) and the plankton itself: -The most common method consist in using a mesh net (plankton net) pull trough the water to collect the organisms that have been caught by the net. The mesh size of the net selected must take into consideration the size of the targeted organisms and the water turbidity. -Other methods use bottles (e.g., Van Dorn bottle, Niskin bottle) that sample a defined water volume at a determined depth. The bottle collects all the microorganisms contained in this water volume. Then the microorganisms are sieved onto a very fine mesh and concentrated in containers. -In lakes, a box-shaped system called a Schindler-Patalas trap can be used. It also samples to a defined depth, and is triggered to close, and then collect the plankton captured inside. - A water pump is convenient to use to collect a important quantity of plankton. |
