Dr. Charles Hohenberg is a Professor of Physics at Washington University in St. Louis. In the lab, Charles does mass spectrometry of noble gases like Krypton and Xenon. He designed and built his own mass spectrometer which is one of the best in the world. With this instrument, Charles measures noble gas isotope ratios in various sources. A major focus is studying meteorite samples to understand early solar system processes. Charles has always been a tinkerer, and he often spends his free time working on various projects around the house. For example, one of Charles’ hobbies is woodworking. He built his own kitchen table and several other pieces of furniture. He received his PhD in Physics from the University of California, Berkeley and has been on the faculty at Washington University since 1970. Charles has received many awards and honors during his career, including election as Fellow of the Meteoritical Society and a Fellow of the St. Louis Academy of Science. He has been awarded the NASA Principal Investigators Award, the NASA Exceptional Achievement Award, and recently the James B. Eads Award honoring engineering or technology from the St. Louis Academy of Science. Charles is here with us today to tell us all about his journey through life and science.
