About Me

About me

My name is Laura Bravo Sánchez and I am a Biomedical Engineer. My research focuses on the intersection betweeen Computer Vision and Natural Language Processing in biomedical images.

Under the tutelage of Prof. Pablo Arbeláez, my advisor and leader of my research group (Biomedical Computer Vision Uniandes), I had the opportunity during my undergraduate and master's studies to improve my skills for both research and teaching others.

I am interested in creating ways in which the tools from computer vision can be applied to biomedical problems, particularly to improve access to health care. Currently I am looking for a Ph.D. that can help me accomplish this goal.

When I am not working on my research I am learning to rock climb, mostly bouldering (I am paralized by heights), embroidering or enjoying nature.

Work Experience

Research Assistant 2019 - Present

Recognition of instruments in laparoscopic and robotic-assisted surgery scenes.

Development of dataset for action recognition in surgical scenes.

Teaching Assistant - Biomedical Image Processing 2017

As the teacher for the laboratories I created new material for teaching machine learning methods applied to biomedical problems, and advised students on their class project. This class teaches students to use machine learning to solve biomedical problems that use visual information.

Undergraduate Teaching Assistant - Biomedical Image Processing 2016

Guided students with the material, taught the review sessions with original material and helped with organizing the class. The topics of this class are focused on machine learning techniques using visual data and their applications to biomedical problems.

3D printing (MeshLab, etc.)

Statistical analysis (Minitab, etc.)

Spanish (Native)

English (C1)

French (B1)

Rock climbing



MSc. Biomedical Engineering 2017 - 2019

Universidad de los Andes

Emphasis on computer vision, machine learning and deep learning. During my thesis I investigated the recognition of different instruments in videos of robotic-assisted surgeries, via the inclusion of language and deep learning. Advisor: Prof. Pablo Arbeláez.



Colombia Crece

During 2018 I was a volunteer mathematics teacher for adults and the elderly at Colombia Crece, an organization created to democratize education in low-income neighbourhoods.

In 2017 I was a member of the sports climbing team at Universidad de los Andes, winning a silver medal in the bouldering competition.

Manos Visibles

For a summer in 2015 I volunteered at Manos Visibles an NGO that helps train leaders in underrepresented and isolated communities in Colombia.

Techo Colombia

From 2012 to 2014 I was a volunteer at Techo Colombia, mostly I helped builing houses in low-income communities and raising funds for construction costs.
