A recent feature on the lab's work and the creation of the new Center for Biological Systems Engineering was published in the Washington Magazine.
Dr. Scott Crick, postdoc in the Pappu lab, was selected to give a talk at the 56th Annual Meeting of the Biophysical Society in San Diego, CA, February 2012.
Albert Mao, MD/PhD student in the Pappu lab, received a cash prize of $100 and a citation from the Biophysical Society as one of the winners of the SRAA student poster competition at the 55th annual Biophysical Society meeting in Baltimore, MD. The award was given to Albert in the Intrinsically Disordered Proteins category.
Dr. Rahul Das, a current postdoc in the Pappu lab, was selected for the postdoc award and spoke at the 5th annual symposium of the Intrinsically Disordered Proteins subgroup meeting prior to the 55th annual meeting of the Biophysical Society's annual meeting in Baltimore, MD. Rahul spoke about his recent findings on bZIP transcription factors. In addition to the speaking opportunity, Rahul received a cash prize of $500.
In December we officially released our CAMPARI modeling package as open source software under the GNU General Public License (GPL) (v3). The package is free to all users and the source code is disseminated in its entirety. Our goal is to facilitate, independent assessments of our solvation model, forcefield paradigm, and sampling tools. Detailed documentation may be found at http://pappulab.wustl.edu/campari. For users of CAMPARI, we have set up a help desk so queries and questions can be sent via Email to email@example.com
Dr. Andreas Vitalis, alumnus of the lab received the 2010 Empiris Award for Research in Brain Diseases. This award was given for his thesis work entitled "Probing the early stages of polyglutamine aggregation with computational methods". As part of this award Andreas received a citation and CHF5000.
Dr. Alan Chen, alumnus of the lab, received an NRSA postdoctoral fellowship award from the NIH. Alan is pursuing his postdoctoral work in Dr. Angel Garcia's lab at Rensselaer Polytechnic Institute and he is working on RNA molecules involved in viral entry pathways.
Albert Mao gave an invited talk at the first Gordon Research Conference on Intrinsically Disordered Proteins. This GRC was held in Davidson College in North Carolina in the summer of 2010.
Dr. Matthew Wyczalkowski, alumnus of the lab, received an NRSA postdoctoral fellowship award from the NIH. Matt is pursuing his postdoctoral work in Dr. Larry Taber's lab at Washington University and he is working on multi scale models of morphogenesis.
Scott Crick gave a talk at the 2010 meeting of the Biophysical Society discussing results from his measurements of polyglutamine aggregation.
