     Research interests:

Dr. Ruzicka's research focus is the study of extraterrestrial samples to better understand solar system and planet formation.  

This includes 1) dust aggregation and melting processes in the early solar system (AOAs, CAIs, chondrules), 2) the origin of silicate-bearing iron meteorites; 3) deformation and thermal histories of chondritic meteorites; 4) the origin of igneous inclusions in ordinray chondrites; 5) the origin of the Moon; 6) HED meteorites and asteroid Vesta; 7) coupled reaction-diffusion processes (CAI rims, coronas in mesosiderites), 8) chondrite petrology and classification.

A comprehensive list of publications can be accessed from the Cascadia Meteorite Laboratory publications page.
