About Me

Hi! I’m Melinda, a consultant and educator on all things face-related. I specialize in facial expressions, FACS (Facial Action Coding System), and facial anatomy. My background in faces originated in academia, migrated to tech, and now lives in the space between art, science, and technology.

I apply my expression expertise to a range of industries (film, game, tech, etc.) and products/media (Emoji, AR/VR face tracking, AAA game characters, photoreal animals, AI, deepfake technologies, etc.). If it has a face, you’re in the right place.
