I love teaching astronomy, geology, oceanography, and physics courses and getting students engaged with exploration, investigation, and discovering! I am a geophysicist who explores environments in the Solar System and exoplanets beyond, studying planetary habitability, trying to answer one of the fundamental questions of astronomy, "Are we alone?". Find my Fall 2024 courses here, all are welcome!

Research Focus

Project funding has been generously supported, especially student projects, by the NASA RI Space Grant Consortium. Contact [email protected] for more information if you'd like to get involved! I use comparative planetary science to understand the habitability of planets and worlds by investigating planetary analog field sites, making astronomical observations, and running computer simulations. Here are some of my recent works:

Students at CCRI who are interested in majoring in either Geology or Physics and want to remain instate can transfer to the University of Rhode Island. There is a Joint Admissions Agreement (JAA) with URI in both Geology and Geological Oceanography and Physics.The first two years of your Bachelor's degree will be completed at CCRI all while earning your Associate degree. Once transferred to RIC or URI, JAA students receive the following benefits:

Up to 30% discounted tuition at RIC or URI depending on your CCRI GPA
Waived application fee
Conditional acceptance to URI or RIC
Personalized advising at CCRI, URI, and RIC
More than 60 majors to choose from
Transfer seamlessly as a junior in your major
