I had the great pleasure of spending a day with Adam Savage to geek out about meteorites! Check out my appearance on this week’s episode of Savage Builds : Forging Excalibur, where Adam attempts to forge a sword out of an iron meteorite. Air date: Friday, July 5th on Discovery, @10pm PDT Savage Builds – … More Savage Builds – I’m on TV!
After a wonderful 4 years as a postdoc at the Space Sciences Lab, it is time for me to move on. I am proud to say that I have accepted a Research Scientist position at Stanford University’s SHRIMP-RG lab in the Geological Sciences Department, beginning July 1st. My new role will entail working with Stanford … More Goodbye Berkeley SSL, Hello Stanford SHRIMP-RG Lab!

Spring 2019 Isotope Geochemistry Seminar Schedule 15 April 2019: Seminar – UC Berkeley Isotope Geochemistry Seminar 4:00pm in 265 McCone Title of Talk: Aqueous alteration in the early Solar System: constraints from oxygen isotopes … More UC Berkeley Isotope Geochemistry Seminar
E-poster for the Lunar and Planetary Science Conference is now uploaded, and can be accessed online at: Click to access 2649.pdf Stop by my poster on Thursday night if you’d like to chat about comet dust, oxygen isotopes, or anything Cosmochemistry related!
Our consortium on Stardust material has published a new article about primitive fine-grained materials found in comet dust. The paper, titled “Fine-grained material associated with a large sulfide returned from Comet 81P/Wild 2” (primary author Zack Gainsforth), takes a look at a large particle called Andromeda, and how it shielded this delicate material upon aerogel … More New Paper on Stardust fine grained material
Thanks to everyone who came out to the CIPS Seminar last week! If you missed it, or have any questions, feel free to contact me for more info.
Check out our e-poster that was presented at the Lunar and Planetary Science Conference last week: Chemical, mineralogical, and isotopic characterization of terminal particles from Stardust tracks. We investigated seven tracks returned from the Stardust mission, and investigated the small comet particles using a wide variety of techniques. We found many sulfide grains, as well … More Characterization of terminal particles from Stardust
This year at LPSC, we will report on the past year of our consortium study of Stardust cometary tracks, with the goal of exploring the chemical, mineralogical and isotopic diversity of materials returned from comet 81P/Wild 2. We extracted six tracks from aerogel tile C2031 using our keystone extraction technique, and studied the materials and terminal … More LPSC Abstract on Stardust Particles
The presence of hydrated minerals in chondrites indicates that water played an important role in the geologic evolution of the early Solar System; however, the process of aqueous alteration is still poorly understood. We investigated the oxygen isotopic compositions of secondary minerals in CR chondrites to constrain fluid conditions on the asteroidal parent body. Calcite, … More New Paper on CR Chondrites
On Tuesday at LPSC 2017, I presented my latest results on the redox conditions for formation of Al-rich chondrules. Al-chondrules are important to planetary science as they represent some of the earliest formed materials in the Solar System; however, the environmental conditions and mechanisms of formation remain largely unknown. You can check out a high-res … More Aluminum-rich chondrules formed under reducing conditions in the solar nebula
