I am a fourth year PhD student in the department of Plant and Soil Sciences at the University of Delaware. I use state-of-the-art techniques such as Eddy Covariance systems and Near Remote Sensing to relate and up-scale gas exchange with plant phenology and physiology. During my PhD, I have been responsible of an Eddy Covariance tower, I collected and processed CO2/H2O, CH4 gas exchange, as well auxiliary meteorology variables. I collected and processed hyperspectral measurements, phenology cameras data (i.e., PhenoCam data) and vegetation indices from spectral reflectance sensors to model and upscale the influence of vegetation pigments and plant nutrients on the ecosystem carbon exchange. I also did laboratory analyses of vegetation pigments and plant nutrients.

During the first two years of my PhD, I did a side project about the “Greenness trends and carbon stocks of mangroves across Mexico”. This was a national scale analysis to identify greenness trends and their relationships with temperature and precipitation in persistent mangrove forest of Mexico (i.e., not directly submitted to land cover use and change) since 2001 to 2015. I also identified the influence of greenness trends on the soil organic carbon (30 cm of depth) and above ground carbon. This study is available as open access in Environmental Research Letters https://iopscience.iop.org/article/10.1088/1748-9326/ab246e.

Before to start my PhD program, I worked for seven years as a Remote sensing analyst for the Department of Geomatics in the National Commission for the Knowledge and Use of Biodiversity (CONABIO), Mexico. There, I worked for the National Mangrove Monitoring Project. During that time, I did many fieldwork activities with different institutions. I led the development of workshops with Mexican Mangroves specialists to identify priority mangrove areas for conservation and management, reviewed and approved different academic projects about the mangrove ecology in the country, and coordinated the development of a guide to homologate methods for the characterization of mangroves at different scales. During my time in CONABIO, I also got a Master’s degree in Geomatics.
