About Me
I am an enthusiastic agronomist and scientist. I am specialized in Multivariate Data Analysis (chemometrics) and the implementation of new technologies the agri-food chain. My research interests focus on Visible, Near Infrared and Mid Infrared spectroscopy, as well as on hyperspectral imaging applications for precision agriculture, food quality assessment and food safety. Curious, enthusiastic and a good communicator, I am experienced in both leading scientific research and in the dissemination and transfer of scientific knowledge.

Research Interests
My research interests are interdisciplinary and comprise the application of Multivariate data analyses (chemometrics) to agronomical sciences.
Some pertinent examples of my work are: the adaptation of sampling methods to the calibration of spatial models in precision viticulture, (see references SC.6, SC 9, CP.19 on the publications list); the assessment and improvement of NIR model robustness for plant breeding purposes (SC.10, CP.23, CP.24, CP. 25); the development of multispectral indexes for spectral imaging (CP. 21, SC.3, SC.8); and the use UAV-based thermal imagery to monitor instantaneous variations in water status within a vineyard (SC. 11). Throughout these studies I used two kinds of data analyses: chemometrics (SC1. to SC.5, SC.7, SC.8, SC.10); and combinations of chemometrics and geostatistics (SC.6 , SC.9, SC. 11).
Scientific Partners
These lines of research resulted from the collaboration between the COMIC team at Irstea-Montpellier, specialized in spectroscopy, optic sensors and chemometrical methods; and several agronomical institutions, involved in plant physiology (EMR), crop modelling for viticulture (Montpellier SupAgro , INRA-Peach Rouge and Universidad Pública de Navarra), post-harvest and advanced agri-food technologies (LPF-TAGRALIA, Universidad Politécnica de Madrid), and the sugar beet sector (Institut Technique de la Betterave). Presently, I am integrated in the (UCD Spectral Imaging Research Group, where use spectral imaging to improve understanding of biological systems and develop algorithms for the analysis of spectral imaging data. Different spectral modalities (VIS, NIR, SWIR, Raman, ATR and FTIR) applied at various spatial scales are explored for this purpose.

INFORMATICS SKILLS
Multivariate Analysis Sofware
Being usually the link between experts on different disciplines, I have consistently been responsible of programming the mathematical solutions required for my research work. As a result, I am a confident user of MatLab, which I started using in 2005. Since then, I have developed my own toolboxes for sampling, modelling and hyperspectral image analysis.
Geographic Information Systems
Regarding Geographic Information Systems, I handled QGIS and 3DField for the visualization of spatial measurements and estimations during my postdoctoral experience at the company Fruition Sciences.
Image Analysis
I am familiar with image processing and analysis sofware ImageJ, which I used as a didactic tool for introducing students to image analysis methods.
Others
I am also a competent user of bibliography managers, particularly Endnote and Mendeley as well as MS Office tools (Excel, including macro programming, Word and Power Point), and Paint Shop Pro. I have some brief experience on database enquiring with SQL (3 months, during experimental work) and I am currently following training on the visual analytics platform Tableau (Coursera, 2021).
