About Me I am a second year computer science PhD student at Vislang Lab in Rice University, advised by Prof. Vicente Ordonez. Prior to this, I obtained my bachelor’s degree in Industrial Engineering from ESPOL (top 1% of the class), where I worked with Prof. Andres G. Abad on machine learning and computer vision. I also worked as a research assistant at INARI Lab on applications of computer vision to retail. I have also shortly worked as a Computer Vision engineer at adaviv. I am interested in computer vision, natural language processing, and machine learning. I am particularly interested in self-supervised learning for video data. I am currently working on multimodal learning for to solve vairous vision tasks using language. As a PhD student, I am always eager to collaborate with other researchers. If you are interested in working with me, feel free to reach out to me via email. Pre prints Generative Visual Instruction Tuning.
