About | Resume | Reel

Hi! I'm a computer graphics senior software engineer at Walt Disney Animation Studios working on Disney's in-house production physically based renderer, Hyperion. As part of the Hyperion team, I worked on the animated films Zootopia (Spring 2016), Moana (Fall 2016), Olaf's Frozen Adventure (Fall 2017), Ralph Breaks the Internet (Fall 2018), Frozen 2 (Fall 2019), Raya and the Last Dragon (Spring 2021), Encanto (Fall 2021), Strange World (Fall 2022), and Wish (Fall 2023), and on the animated series Baymax! (Summer 2022) and Zootopia+ (Late 2022). I am currently working on various unannounced projects beyond 2023.

I am also concurrently finishing as a Master of Science in Computer Graphics candidate at Cornell University's Program of Computer Graphics. My main areas of research interest are in global illumination lighting and rendering, GPU algorithms, and physically based simulation.

Previously, I did my undergraduate studies at the University of Pennsylvania and contributed to CG@Penn as a TA and researcher.

I interned twice at Pixar Animation Studios (summer 2011 and summer 2013), and interned at Dreamworks Animation in summer 2012.

My computer graphics work can be found at my technical blog, "Code and Visuals", and on Github I'm betajippity.
