Holland Lab Attends ENC Conference

The Holland Lab attended the Experimental NMR Conference (ENC) at Asilomar Conference Center in Pacific Grove, CA https://www.enc-conference.org/Conference-2024. This is the premier conference in experimental magnetic resonance including solution and solid-state NMR and magnetic resonance imaging (MRI). The lab gave two talks and presented three posters. Lab post-doc, Dr. Kevin Chalek's talk was on Sunday (4/7) in the Young Scientist Symposium titled "Studying Sidechain Interactions in Dragline Spider Silk Fibers Using MAS Solid-state NMR and DNP". Kevin also presented a poster on the same topic Tues/Thurs. Research scientist and SDSU NMR Facility Manager, Dr. David Onofrei gave a talk in the Biomolecular Solution NMR Session on Tuesday (4/9) titled "Using CS-ROSETTA to Probe Assembly of Intrinsically Disordered Spider Silk Proteins in Solution". PhD grad student, Hannah Johnson presented a poster on Tues/Thurs titled "Solution NMR of Liquid-Liquid Phase Separation in Native Major Ampullate Spider Silk Proteins Indicates Arg and Tyr Influence Pre-Assembly". PhD grad student, Yuan Li presented a poster on Mon/Wed titled "The Calcium Sites of Hydroxyapatite with Different Morphologies and Crystal Phases Investigated by 43Ca MAS Solid-state NMR". Yuan was also awarded an ENC graduate student travel award to support her attendance. Congrats Yuan!!! Below is a picture from the Lab Dinner at the Fish Hopper in Monterey where we caught up with Lab alumni, Dr. Haley Swanson, who is now Bruker NMR West Coast Sales Rep. We had fantastic discussions regarding our upcoming 600 MHz Ascend NMR magnet install and some plans for new cutting edge probes in Diffusion and Solid-state NMR for the future. Check out the picture from dinner below: ...
