Professional Research and Educational Interests

Utilizing 3D Printed Planetary Terrain Models in STEM Education:This NSF-funded project seeks to understand the effectiveness of using 3D printedtactile models of various planetary terrain (impact craters, volcanoes, canyons, as-teroids, etc) combined with professional mentoring and instruction to increase therepresentation within STEM majors of students who are blind or visually impaired.

Effects of Student Choice in General Education STEM Courses:This project is approved for human subjects research by the University of Arizona(IRB #1608777887). Students are allowed to individually customize the curriculumbased on their own grading criteria. Their level of engagement and performance isthen tracked over the course of each semester. The research involves evaluating theeffects of their choices on their levels of interest, engagement, and performance inscience courses.

Innovative Visualization Techniques in Earth and Space Science:Developing ray-tracing computer code for production of high-resolution visualiza-tions for researchers and science teachers. To date over 100 unique animations havebeen produced to help demonstrate concepts such as planet formation, near-Earthasteroid orbital dynamics, planetary motion, seasons, phases, eclipses, and historicalscience experiments.

Orbital Evolution of Small Solar System Bodies:Conducting N -body numerical simulations of orbital evolution, with particular em-phasis on resonant interactions between planets and small bodies, such as with Tro-jan asteroids and quasi-satellites of the terrestrial and giant planets. Other typesof modeling include the production and orbital evolution of asteroidal and cometarydust particles and the origins of interplanetary dust particles collected from Earth’satmosphere.

Terrestrial Planet Formation and Dynamical Evolution:Modeling the mid- and late-stages in the formation of Earth-like planets utilizingstatistical and N -body numerical simulations. Recent focus is on dynamical conse-quences of Mars-mass companions in various co-orbital configurations with a proto-Earth, with the aim of constraining the origin of the moon-forming impactor.
