About Me

Hi! I am Brian, I am a Postdoctoral Research Associate working with Prof. Toby Breckon at Durham University in Durham, UK. My research is focused in Machine Learning for computer vision, currently working on anomaly detection and out-of-distribution detection. My research also includes multi-view geometry, object detection, Vision Transformers and neural radiance fields. I am part of the VIViD research group.

I hold a PhD in Computer Science from Durham University and an Engineering degree from the Autonomous University of Yucatan, Mexico. I am an experienced Python and PyTorch developer, although I also have some experience with Android development (in both kotlin and Java). If you have any idea of a project or you want to collaborate, reach out!

Education

Durham University

PhD Computer Science

Department of Computer Science, 2019 - 2024

A globally outstanding centre of teaching and research excellence, a collegiate community of extraordinary people, a unique and historic setting – Durham is a university like no other.

I did my PhD in the Department of Computer Science at Durham University from 2019 to 2024. I worked under the supervision of Prof. Toby Breckon and I worked in a project for automatic detection of threat items in X-ray security imagery in airports, focusing specifically in the incorporation of multi-view geometry. I also did some research in NeRFs. I received a scholarship from the Mexican Council of Science and Technology (CONACyT) for this period. I was the president of the Durham Mexican Society for the 2020/21 academic year.

Durham University

MSc Internet Systems and E-Business

Department of Computer Science, 2017 - 2018

During my time in the Masters at Durham University I was able to develop my skills as a software developer and project manager. I also got a CONACyT scholarship for this period.

Universidad Autónoma de Yucatán

BEng (Mechatronics)

Faculty of Engineering, 2011 - 2016

La Facultad de Ingeniería tiene como misión la formación integral de recursos humanos, a nivel profesional y de posgrado, en las áreas de las ingenierías y la contribución al avance científico y tecnológico para el desarrollo sostenible de la sociedad.

I did my BEng (Metchatronics) (Licenciatura under the Mexican education system) at the Universidad Autónoma de Yucatán, Mexico. Although my current research is focused in Computer Vision, my early formation in engineering gave me the skills to develop embedded and robotic systems. My undergrad thesis was developed under the supervision of Dr. Francis Avilés.

A Little More About Me

Apart from my research in computer vision, I also enjoy playing Volleyball and Squash. I’ve been part of a few band at Durham where I play the drums and sometimes the bass. I played the bass with the CVPR 23 houseband :)
