About the author


Is doing Integrated M.S/Ph.D. at Gwangju Institute of Science and Technology. He has Bachelor of Science in Computer Engineering at the Federal University of Rio Grande do Norte (Brazil) in cooperation with the California State University, East Bay, where he participated in Science without Borders government exchange program. Currently working at Integrated Circuits and Systems Lab.

Areas of interest

This Blog is intended to be a complement of the author studies and events. Hopefully helping anyone interested in the content.

It’s interest for technology began at “Instituto Maria Auxiliadora” High School, where he had the opportunity to deal with educational robotics extra-class activity, where Professor Alexandre Amaral gave classes using LEGO Mindstorms kits to teach various topics from architecture assembly to programming introduction. After, the OBR (Brazilian Robotics Olympiad) was presented to put into practice the knowledge acquired. The mission is based on a firefighter robot that needs to follow a black line and to dodge possible obstacles on the way, at the end rescuing a victim represented by a soda can. Our team successfully got the first place in the state region, and 5th place on the national level.

The above image was posted on local outdoors after our team won the state level competition.


While competing, this amazing crowd from school class was cheering.

Fortunately, the author passed the national exam “ENEM” before finishing High School last year, ingressing on “Science and Technology” undergraduate course at the Federal University of Rio Grande do Norte. While participating in robotics competition before, the author met professor Aquiles which helped to organize the competition. From there, the author searched Aquiles to participate in Scientific initiation inside the university, having opportunities to learn about educational robotics, web and app development, embedded systems, also to participate in various events involving robotics competitions, educational robotics lectures, and Arduino workshops.


The robot structure is built with cardboard to lower the final price, the embedded system consists of low cost motors and sensors, with an Arduino nano to control the system. The Bluetooth module communicates with a cellphone, so the user can control different modes of operation.

Right after finishing the undergraduate second year, the author applied to participate on Science without Borders government program being successfully selected to study at California State University, East Bay. There, he could improve his English language living with native English speakers, and experience different cultures from principal nationalities in the world, California is well known to aggregate people from various countries.

The first contact with microelectronics came while taking professors Tandon VLSI class, by using open source tools such as Magic for layout and IRSIM for simulation. After the class finished, the author searched the professor to participate on a university project, Tandon suggested the author to begin the study of FPGA architectures. From Fall until Spring of 2016 the basic concepts of FPGA architecture were developed using a mix of Mentor and IBM VLSI tools, at Summer of 2016 the Science without Borders allowed the students to apply for an internship or university research, the author chose to continue on with FPGA project.

While finishing the undergraduation, the author participated in a data science competition “Python IMD challenge” where he won the first prize. More detail can be found here.


Later on, he accomplished to fabricate a fully working chip for the undergraduate thesis on FPGA architectures. More detail can be found here.


On the last year of the undergraduate course, the author was selected to the Gwangju Institute of Science and Technology Global Internship Program (GIP), where he participated in a 2-month internship at the Integrated Circuits and Systems Lab. Producing a conference paper and achieving the most popular posters award. More detail can be found here.

Furthermore, he got accepted at GIST in a Integrated M.S/Ph.D. program, being always glad to meet opportunities as life brought until now.
