Big welcome to Tan and Parvathi. Tan has an inorganic chemistry background and Parvathi has a microbiology and biochemistry background. Cannot wait to see what new things we can do through combining our talents. Tan will work on Fe-Mo-sulfide systems and Parvathi will focus on electron transfer in photosynthetic and chemolithoautotrophic sulfur bacteria. Cannot wait to see what new things these new talents may find.

Rachel successfully defended her dissertation!

posted : 2023-12-02 00:00:00

Rachel has successfully defended her dissertation, "Enhancing Our Understanding Of Ancient Oceans Through The Investigation Of Molybdenum Behavior Under Sulfidic Conditions". Rachel has done a beautiful job with a difficult Fe-Mo-sulfide project. She has published two papers on this topic and is working on the third! Rachel will start her NSF postdoc fellowship in South Carolina. Rachel is enthusiastic in Geoscience education and has her own channel and tens of thousands of fans on YouTube. It is always difficult to say Goodbye! We cannot wait to see what new things Rachel will create! Enjoy your new journey, our dear friend! (It is a pity Jie could not walk with Rachel; she did not walk with Hugo either. what a "horrible" advisor! But gladly, Kate was able to help. The picture is of Kate, Rachel, and Jim @UTEP convocation.)

It has been a long journey for Hugo (and unusual in many aspects). But you know what? Hugo kicked out the obstacles in his way one by one! It is Hugo's day and he successfully defended his dissertation. Hugo was the one that initiated the purple sulfur bacteria project for the NanoGeoBio Laboratory and has completed studies for several metal sulfide systems. Thanks for heavy lifting this new project and good luck for your new phase of life! Way to go, Hugo! We will miss you!

Jie (more accurately, her group) was recognized for her research that addresses the existing gap between the understanding of the structure, bonding, and speciation in transition metal (TM) sulfide species. She aims to reveal the underlying reaction mechanisms of TM-sulfide systems and to connect their interactions with the electronic states observed in TMs under various conditions.
