Research Interests

I am advised by professors Steve Desch, Christy Till, and Devin Schrader. My research involves conducting vertical furnace experiments at the Experimental Petrology and Igneous processes Center (EPIC) lab led by PI, Christy Till, to further understand chondrule formation. Chondrules are key to understanding the energetic processes that were present during the initial stages of the Solar System, but their formation mechanism(s) remains unknown. Nebular shock models are currently the most favored, but it is uncertain whether porphyritic chondrules, the most dominant type of chondritic texture, can form at the high cooling rates consistent with the planetary embryo bow shock model.  The purpose of my experiments is to explore a wide variety of parameter combinations to test the validity of this model.
