Biographical Information

José Luiz Carvalho de Souza Dias was born on 4th October, 1988. He is the oldest son of Reinaldo de Souza Dias, a metallurgical engineer and a lawyer, and Dulce Maria Carvalho de Souza Dias, a pediatrician; brother of Ricardo Carvalho de Souza Dias, an agronomy undergraduate student.

In 2007, José began his Agronomy undergraduate program at Sao Paulo State University (Universidade Estadual Paulista – UNESP/Jaboticabal, SP/Brazil). As an undergraduate, José completed many activities inside and outside the University. In 2008, he completed an internship at a sugarcane mill called Santa Rita Plant S/A Sugar and Alcohol. His main activities there were learning about and observing closely how each sector works. He also was a member of the CAPjr (Junior Consulting Company) in 2008, as a team member of the agricultural year, attending company meetings, organizing and getting sponsorships for 'XIII Peanut, Corn and Soybean Field Day', held during the harvest 2008/2009. From November 2009 to February 2011, he was a member of the GIEU (Group University Business Integration), working as representative of the events Committee. His main activities in this group were to attend weekly meetings, to organize and to participate in events, technical visits in and out of Brazil and volunteer activities with the group, formed by Agricultural Engineering students. From September 2009 to March 2011 he worked in the Soils and Fertilizers Department, at Sao Paulo State University (Universidade Estadual Paulista – UNESP/Jaboticabal, SP/Brazil), as a Plant Nutrition Intern. His main activities in the Soils and Fertilizers Department were to develop researches with different methods of determination of dry matter content and the amount of nitrogen in plant's leafs. From July 2011 to November 2011 he worked at the Range Cattle Research & Education Center, University of Florida/IFAS, as an intern, advised by Dr. Brent A. Sellers. During his internship, he worked with Weed Science, conducting experiments in order to determine the selectivity of several cultivars of tropical forages for new herbicides.

After he finished his undergraduate course, he worked at a farm called Agropecuária Jacarezinho, in Valparaíso, SP/Brazil, from February 2012 to June 2012, as an Agriculture Trainee. He was responsible for all cultivation of the rubber crop, besides contributing in the analysis of field data and operations planning in the culture of sugar cane, such as planting and harvesting. From July 2012 to August 2014, José worked at a sugarcane Mill called Usina São Martinho, in Pradópolis, SP/Brazil, as an Agriculture Trainee. His main activities, at first, were to work for a time in all agricultural sectors of the plant, with the objective of learning the entire process and acquiring a systemic view. After this initial period of job rotation, he stayed in the quality of agricultural sector, acting more directly with weed science, pest control and implementation of orders in aid of a software called Ifrota. From March 2013 to December 2014, José completed his Masters Degree in the Crop Production Department at Sao Paulo State University (Universidade Estadual Paulista – UNESP/Jaboticabal, SP/Brazil) advised by Prof. Dr. Dagoberto Martins, developing research projects in the area of herbicide selectivity in pre-budded sugarcane seedlings.

In the Fall of 2015 Jose returned to the station, now as a P.h.D. student under Dr. Brent A. Sellers. The main objectives of his research are i) assess the effects of simulated rainfall volumes on smutgrass control and bahiagrass selectivity treated with foliar applied hexazinone; ii) evaluate the efficacy of smutgrass control using the weed wiper method; iii) quantify the response of smutgrass and bahiagrass herbage mass to burning, stocking density, and hexazinone application rate; and iv) determine the impact of burning and stocking density on the nutritive value of smutgrass and bahiagrass in order to evaluate the impact of smutgrass cover on cattle performance using nutrition models..
