About

Hi, I’m John. Here is some relevant (and possibly irrelevant) information about me:

• I am based in Brooklyn, New York.

• I have an interest in physically based shading, high-performance parallel algorithms, digital humans, and visual effects.

• I am currently a Sr. Staff Graphics Engineer at Qualcomm’s Snapdragon Studio, with over 8 years of prior rendering experience at Unity Technologies.

• What I love about real-time computer graphics is how it forces us to reconcile our observations of light, materials, and geometry with tight hardware constraints; resulting in clever ideas, and great engineering.

• You can find me at industry conferences, where I love to share the knowledge I learn along my way. I recently spoke about my work on hair shading and rendering at SIGGRAPH 2022, which you can check out here.

• I share the results of some of my amateur technical art work on this instagram page.

• In my free time I like to boulder or read. My favorite book is William Gaddis’ The Recognitions.

• Here is my slightly old resume and a reel of some stuff I have worked on.

• Otherwise if you would like to reach out, you can contact me directly at parsaiej@gmail.com
