Dr. Spiczak's research explores the composition, origin and acceleration of cosmic rays via characteristics of high energy particle debris raining down on Earth's surface after these spacefaring nuclei collide with Earth's atmosphere. He was a research scientist at the Bartol Research Institute of the University of Delaware studying Cosmic Rays using SPASE (South Pole Air Shower Experiment) and AMANDA (Antarctic Muon And Neutrino Detector Array) and continues such work at UWRF using the IceTop surface array of the IceCube cubic-kilometer neutrino telescope at the South Pole. He was a lead member of the task force for active learning classrooms on campus and mentors UWRF's high-powered rocket teams competing in NASA's Collegiate Rocket Competitions along with the Physics Student robotics teams.

During graduate school Arriety used perturbed angular correlation (PAC) spectroscopy to study lattice locations and site preferences of atoms in rare-earth aluminides having C15 structure. After graduate school she followed a somewhat circuitous path to teaching, and has found herself interested in alternatives to traditional lecturing that allow more student involvement and participation as well as online learning. In addition to her teaching for the math, physics and STEMteach programs, she is the lab manager for the physics department. Arriety works with students and does outreach through the Girls in SCIENCE event and has mentored student teams for the Wisconsin Space Grant Consortium’s High-Powered Rocket competition.
She currently sits on the Faculty and Academic Staff Development Board and the Faculty Compensation Committee. In addition to this work she has participated in the Evidence Based Teaching Fellows program and the GREAT Falcon STEM Fellows program.
Outside of the university she works and volunteers in several fields. She is available as an independent consultant and has served on the board of directors for several companies and organizations. She also works with the Wisconsin Science Olympiad developing and running events at state and local levels.
