Science, Interpretation, and creativity


Studying microplastic, larval ecology, and comb jellies as a marine biologist was thought-provoking and fascinating work. But when I got to share stories about my research with lab visitors and watch their faces light up with curiosity—those were my best days as a scientist.


In the years following this realization, I slowly pivoted towards science communication. I taught children marine science, guided my own nature tours on foot and by bike, wrote science news stories for local and national outlets, published my illustrations and photography, communicated science for the San Diego Natural History Museum, and more.


Today, I am the owner and operator of North Star Naturalist, providing immersive outdoor tours for curious locals and visitors in San Diego County.


I am a Certified Interpretive Guide with a B.S. in Marine Science from Eckerd College and a Master's from the highly regarded Science Communication Program at U.C. Santa Cruz.
