"As to the future, there are more experiments to do, music to play, people to enjoy, and surprises to catch me unaware," says Dr. Chalfie in his Nobel autobiography. Dr. Chalfie is widely recognized for his pioneering research on the 'green fluorescence protein' and is one of three recipients of 2008 Nobel Prize in Chemistry. Dr. Chalfie is a chair of the Biological Sciences Department of Columbia University. His research focuses on addressing the neuronal cell fate determination and the molecular basis of mechanosensation. He is also involved in studies on neuronal degeneration, microtubules and channel structure and function, which are facilitated through the development of new experimental methods, such as green fluorescent protein and reconstituted GFP as gene and protein markers, and generation of temperature sensitive C. elegans gene. Dr. Chalfie has published over 100 papers to date and at least 20 papers have over 100 citations.

Associate Professor, Department of Radiology, Harvard Medical School

Associate Professor, Center for Molecular Imaging Research, Massachusetts General Hospital


Dr. Josephson is a member of the Martinos Center for Biomedical Imaging, a member of the Center for Translational Nuclear Medicine and Molecular Imaging, and an Associate Professor at Harvard Medical School. His research focuses on the design and uses of magnetic nanoparticles, near infrared fluorescent (NIRF), and magneto/optical probes for use in ares of biology, chemistry and physics. He has developed MRI and NIRF detectable nanoparticles for use in lymph node delineation and brain tumor delineation. He is also involved in the development of annexin V based probes for imaging apoptosis. Dr. Josephson is a co-founder of AMAG Pharmaceuticals and a co-founder and consultant to T2 Biosystems, a company developing MR based assays and sensors. He has published over 100 peer-reviewed publications and has 30 issued US patents.
