Dr Mark Szczelkun from the University of Bristol receives his 2004 BBS Medal from David Trentham at the Response to DNA Damage: Insights from Chemical, Biological, Structural Biology and Cellular Studies meeting at the University of Sussex which took place between 19-21 September. He presented a lecture entitled “A molecular motor that introduces double strand breaks into DNA”. What are Mark’s thoughts about receiving the BBS Medal? “It’s nice to know your peers think you are doing the right thing!” he jokes. On a more serious note, Mark feels it is important for biophysics to get the recognition it deserves. And that’s certainly something the BBS agree with.
