Creative Development Director
I graduated from the Federal University of Pernambuco (UFPE), in Brazil, with a bachelor’s degree in industrial design, with a one-year program at the Savannah College of Art and Design (SCAD) where I studied motion media design. Nowadays, I’m part of the design team at Underknown where we develop the static and moving branded graphics for their shows. I love the art and math behind all things 2D and 3D and, down the road, I wish to pursue a master’s degree in computer science since I have a special enthusiasm for the design and engineering dialogue.
My passion for computer graphics and interaction was first sparked by experimenting with a Commodore64 home computer in the late 1900s. This passion ultimately became a career that led me to the 2006 and 2007 SIGGRAPH Conferences, which played a pivotal role in a transition into the feature film visual effects industry. After completing my MFA in animation and visual effects, I began an academic career that continues today as I direct the Digital Media & Virtual Production Program at Drexel University, where I teach immersive media, motion capture, and virtual production. Over these years, SIGGRAPH has been integral to inspiring and enabling my career, teaching, and the students I mentor. I’m honored and excited to be part of the 2023 committee bringing the next iteration of this conference I love to life.
