Autumn Leica Lecture


These are always excellent. This autumn’s lecture will be given by Prof. Tajkip Ha from the Department of Physics, University of Illinois at Urbana-Champaign and is entitled
“Single Molecule Biology: One, two, three and four”.
Tuesday 11th October at 5pm
Lecture Theatre 3 in Life Sciences Building with a post lecture reception at 6.15pm in the foyer outside the lecture theatre.

Professor Taekjip Ha received his Ph.D. in Physics in 1996, from the University of California, Berkeley. Prior to joining the Physics faculty at the University of Illinois in August 2000, he was a postdoctoral fellow at Lawrence Berkeley National Laboratory (1997) and a postdoctoral research associate in Steven Chu’s laboratory in the Department of Physics at Stanford University (1998-2000). He was named 2001 Searle scholar. In 2005, Dr. Ha was named an investigator of the Howard Hughes Medical Institute. In 2008, Dr. Ha was selected by the National Science Foundation to receive a grant to establish and co-direct the Center for the Physics of Living Cells at the University of Illinois.
Professor Ha has achieved many “firsts” in experimental biological physics–the first detection of dipole-dipole interaction (fluorescence resonance energy transfer, or FRET) between two single molecules; the first observation of “quantum jumps” of single molecules at room temperature; the first detection of the rotation of single molecules; and the first detection of enzyme conformational changes via single-molecule FRET. His most recent work, using single-molecule measurements to understand protein-DNA interactions and enzyme dynamics, has led him to develop novel optical techniques, fluid-handling systems, and surface preparations.

Professor James Fawcett, Cambridge Centre for Brain Repair, will be giving his seminar on 03 October 2011 16:00-17:00 in Lecture Theatre 2, Life Sciences Building.
He is an excellent seminar speaker – well worth attending.

Prof. Fawcett’s research interests focus on three related areas of neurobiology.

Axon regeneration in the damaged CNS: inhibition of axon growth by inhibitory proteoglycans in the extracellular matrix, to increase the intrinsic regenerative potential of axons, & using integrin engineering and local protein translation.

Plasticity in the CNS: is turned off in adults by extracellular matrix structures called perineuronal nets. Lab works on actions of these, and methods to modulate their function to improve functional recovery and memory in the adult CNS.

Interfacing the nervous system with electronics: microchannel interface for permanent extracellular recording
