Steve’s got Talent!

Obey Your Master!

Congratulations to Ben, who has successful obtained a Masters in Chemistry, with a thesis examining the use of Rheo-NMR in aligning liquid crystal phases for the measurement of residual dipolar couplings in protein structure determination. Good effort dude! Ben is continuing his studies and (after he has washed his hands) will be taking up a […]

Eddie Comes to Town!

Maiden! Maiden! need I say more? Thats what I call a proper group meeting. Thanks to Max for designing the Team Biophysics Maiden-esque T-shirts..genius…..if only Giraffes could shred…  

Auf Wiedersehen !

Farewell to Katharina 😉 It’s been cool having Katharina Meyer around doing her Internship, now Hurricane is returning to Germany to complete her studies. Here we are saying farewell with Lily’s patented dumplings recipe ;-), and here is Katharina on the top of Mt Ngauruhoe modelling her farewell hat !
