A blog made with pictures, broken English and my vague "castellano" language.

Thanks Brian Hua for pushing me to make this blog. Work hard Brian...

This little mountain (about 10.000 Ha, 25.000 acres) call Sierra de Carrascoy, is where I grew up. How can you place the mountain in the world, HERE. My father used to work in a big farm on this mountain, so I had the chance to explore what was going on in these hillsides.

Aquí una preciosa vista de la umbría de la Sierra de Carrascoy, termino municipal de Alhama de Murcia. Como localizarla en el mundo? AQUI La foto esta realizada desde el Rio Guadalentin con la cámara de Carmen Lopez (la chica con la que comparto casa y crios); Panasonic Lumix DMC-LX3.

Este blog lo actualizo según la vida (trabajo, familia, etc...) me va dejando tiempo, por tanto irregularmente.


Welcome to my small part to help build up science

En mi taller. Uno de los sitios donde más feliz he sido trabajando. Bloom Lab. Davis, Ca. 2007


1991-1995: Técnico especialista en explotaciones Agropecuarias. Lorca, Murcia, Spain.

1996-1998: Ingeniero Técnico Agrícola en Horticultura y Jardineria. Orihuela, Comunidad Valenciana. Spain.

1999-2001: Ingeniero Agrónomo. Orihuela, Comunidad Valenciana. Spain.

2002-2006: Ph.D. on Plant Nutrition: "Nutrients and water management in pepper plants (Capsicum annuum L.) under saline conditions". Centro de Edafología y Biología Aplicada del Segura. Consejo Superior de Investigaciones Científicas (CEBAS-CSIC). Murcia. Spain.

2007-2010: Postdoctoral at UC Davis, Plant Sciences Department, Arnold. J. Bloom Lab.

2011-Present: Postdoctoral at CEBAS.CSIC, Biology of Stress and Plant Pathology Department, Enrique Olmos Lab.


My background as researcher is a cocktail of plant nutrition and plant physiology sciences, with experiments in the field, greenhouse, growth chambers and in the lab, plant species that include Rosemary, Henna, Wheat, Pepper, Tomato, and Arabidopsis, and key words that include fruit production, fruit quality, fertilization, salinity, drought, and climate change. I think such as mix is something unusual today, because as much you cover as less you tight or as WordReference say, "Jack of all trades, master of none". The good think is that I do not want to be master of none, and I firmly believe that I can take advantage of this mix to understand plants and what matter and what not, in order to perform the experiments I am working on.  

Something quite stable during my career is that I have worked always with the whole plant to  understanding how they respond to the environment. Now (and with a little of luck also in the future) I am working on the response of different plants to nitrogen dose and source (nitrate, ammonium and amino acids) with the goal of maximize sustainable productivity of agricultural system by increasing nitrogen use efficiency. Nitrogen, probably the best friend of plants, very often limits production and it is easily lost from agricultural systems to the surrounding environment where it becomes an economic loss to farmers that can degrade air and water quality.  My work couples classical plant physiology approaches with modern cell biology tools thanks to the researcher team I am working with. We use a variety of experimental technicques, including growth experiments on control climate chambers, leaf gas exchange, biochemistry, microscopy, metabolite analysis, isotope discrimination and 15N labelling.
