Momentan, activitatea de cercetare este axata pe identificarea unor raspunsuri ecofiziologice si biochimice la halofite, in conditii de stres natural si indus experimental. Stresul abiotic la plante reprezinta in zilele noastre un subiect intens studiat pe plan mondial; in special stresul hidric si cel salin se prezinta ca unii dintre cei mai puternici factori limitativi in viata plantelor, si mai ales pentru plantele de cultura (care in mod obisnuit nu pot supravietui la concentratii ridicate de saruri in solutia solului). Descifrarea si intelegerea mecanismelor ce contribuie la rezistenta plantelor la salinitatea ridicata joaca un rol crucial in oferirea unor posibile solutii concrete pentru agricultura viitorului (biosalina), care va trebui sa asigure resurse nutritive pentru o populatie in continua crestere. La ora actuala, conform datelor oficiale, 1,1 miliarde locuitori traiesc in saracie extrema, iar circa 850 de milioane sunt afectati de subnutritie.
In conditiile in care in 2020, populatia Globului se va ridica la aproximativ 8 miliarde, iar salinizarea suprafetelor agricole este in continua crestere, este de inteles interesul crescut pentru studierea mecanismelor ce intervin in toleranta la conditiile hipersaline ale mediului.

Activitatea mea de cercetare se rezuma la peste 30 de articole stiintifice, publicate in tara si in strainatate (unele in jurnale cu factor de impact), si la 5 carti de specialitate, 3 ca singur autor (dintre care una in limba engleza) si 2 ca prim autor. Am efectuat trei stagii de pregatire in strainatate, dintre care unul, in calitate de cercetator invitat de prestigiu si am fost director de grant in cadrul unui proiect national de tip TD.

Grupul nostru este implicat intr-un proiect international: COST Action FA0901 - Putting Halophytes to Work - From Genes to Ecosystems, axat pe abordarea interdisciplinara a halofitelor. In cadrul acestui proiect, sunt specialist in cadrul retelei nationale de cercetatori
(http://www.cost-halophytes.org/index.php?option=com_comprofiler&task=userProfile&user=107&Itemid=4)
si detin si functia de "Substitute Member" in cadrul Comitetului de Management pentru Romania (http://w3.cost.esf.org/index.php?id=182&action_number=FA0901).








Detalii (en) :
Currently, my work is focused on identification of some ecophysiological and biochemical responses in halophytes, in natural and experimental salt stress conditions. Abiotic stress in plants is a very intensely studied issue in plant biology. Drought and salinity are two major environmental factors determining plant productivity and plant distribution. The crops (conventionally called salt sensitive species or glycophytes) are not usually able to survive in high salinity concentrations occurring in rhizosphere. Understanding and dissecting salt stress pathways in halophytes represent a necessary condition in order to propose real solutions for agriculture of the future (which is expected to be biosaline). The actual agriculture needs crops to be more and more resistant to salt and drought conditions, since it will be “forced” to provide food for a continuously increasing population. Nowadays, despite unprecedented global economic growth, 1.1 billion people continue to live in extreme poverty and more than 850 million people suffer from chronic hunger while ecosystems are being threatened as never before (FAO data). Here are many different projections, suggesting that human population will increase over 8 billion by the year 2020 that will worsen the current scenario about food insecurity. In this whole context, the interest for understanding the major salt stress mechanisms in plants reveals as a main objective for plant sciences and finally, for the agriculture security.

My research activity could be resumed on over 30 papers, published in national and international journals (some of them in ISI journals). In addition, I have published 5 books, 3 written as single-author (one of them - in English) and 2 as first author. I have developed 3 scientific missions in labs from abroad; in one of them, I activated as invited researcher.

Our scientific team is also involved in a COST project: COST Action FA0901 - Putting Halophytes to Work - From Genes to Ecosystems, focused on an interdisciplinary approach of halophytes. In this project, I’m researcher with expertise in halophytes anatomy and ecology (http://www.cost-halophytes.org/index.php?option=com_comprofiler&task=userProfile&user=107&Itemid=4). Moreover, I’m Substitute Member in Management Committee for Romania part (http://w3.cost.esf.org/index.php?id=182&action_number=FA0901).
