Universidad Nacional de Colombia (National University of Colombia), Escuela de Biociencias, Master in Biotechnology
My career has been oriented in the areas of biology, biotechnology, microbiology, analysis and execution of experimental designs, process optimization, molecular biology, DNA extraction, electrophoresis and PCR. In the agricultural field, management of cassava, yam and sweet potato crops, evaluation of biofertilizers, inorganic fertilization, data collection in the field, isolation and evaluation of soil microorganisms with beneficial activity, isolation of pathogenic microorganisms from soil and plant samples. I also work in the areas of bioreactor management, microalgae culture, extraction of biomolecules such as fatty acids, probiotics, coordination of courses, writing of scientific articles, formulation of research projects.

the use and environmental impact of chemical fertilization. One of the main crops of the Colombian Caribbean
is the sweet potato, due to its high fiber, mineral, vitamin and antioxidant contents, making it highly demanded
worldwide, and leading to the search for better cultivating conditions. The purpose of this study was to determine
the response in field performance of super-elite sweet potato vegetative seeds to the inoculation of microorgan-
isms mixed with nitrogen fertilization (NF) in doses of 50 and 75 %. Field experiments were carried out in two
areas of the Colombian Caribbean using the 3×2 factorial design, where each treatment consisted of 3 plots of
36 m2. Results show that for the area of Sabanas Colinadas the inoculation of the combination of Azotobacter
chroococcum-IBCR19, Azospirillum lipoferum-IBSC7 and 75 % NF, produced higher yields (14.5 ton/ha), with a
significant increase of 32 %, compared to the treatment with no inoculation and 100% NF. For the Montes de
María area the highest yield (15.3 ton/ha) was obtained with the inoculation of Azotobacter vinelandii-IBCB10 and
75 % NF, showing an increase of 21 % compared to the treatment having no inoculation and 100 % NF. In both
areas, field yields increased with inoculation and there was a 25 % reduction of NF. These results demonstrate the
increased potential of using microorganisms in sweet potato production systems of the Colombian Caribbean.
