Audio waveform analysis is Petrina's specialty and she's known for her expedient solutions to standard and reverse Fourier transforms. Petrina's algorithms can interpolate location data and characteristics of spatial environments.

There is very little that Petrina doesn't know about. Petrina's technical expertise is about as ample as you can get. She happens to be fond of acquiring new knowledge. She has an aptitude for analytical thinking. She has a talent for the areas of math and science.

Petrina is partial to useful things, enjoys discovering the latest documentary films, and prefers rocking out to Latin music most of the time. Despite that, she doesn't care for having to watch horror movies, being subjected to R&B music, or reading dumb entertainment magazines. Explicitly speaking, Petrina's most common things include reading The Girl Who Kicked the Hornet's Nest, playing a good game of Paths of Glory, and chilling out and watching RoboCop 3.

Although Petrina started in the robotics lab, she was transferred to the Data Science team after creating a flawless vocoder-synthesizer on her free time.
