Scientific royalty

Shortly after joining the Ludwig Institute, I was invited to a board dinner where I had the pleasure of sitting next to our new scientific director, . I remember being particularly intrigued by the “Sir” on his nametag. When was he knighted? Why? We got to talking, and although I never learned the circumstances of his knighthood, I was captivated by his fascination with the Institute, its approach and the achievements that resulted from its independence and flexibility.

At the time, he was particularly excited about a Ludwig discovery, the 806 antibody, which he felt exemplified Sir David Lane Ludwig’s distinct approach to research. We encourage collaborations of Sitting down with David Lane laboratory and clinical research that not only further our understanding of , An internationally recognized leader in ability to tackle big problems.

On-off switch Many complex diseases have their roots in early human development. Susceptibility to disease is, in part, the result of epigenetic regulation of the genetic blueprint. Epigenetics is the study of changes in gene activity that don’t involve alterations to the genetic code but are passed down to at least one successive generation. The great hope for epigenetic research is that with the flip of a biochemical switch, researchers could instruct genes that play a role in many diseases—including cancer—to lie dormant.

The approval of ipilimumab to treat advanced metastatic melanoma was a game changer not only for the thousands of people fighting this disease, but also for the entire field of oncology.

It’s the United States, are obstacles we’ve overcome. We have the World Cup of wind bands and quite what would you collaborative and collegial relationships an honor. change about the with industry. Contracted research system to move is a thing of the past and we’re now Click here to listen to Rolling Thunder by research from undertaking collaborative research to Henry Fillmore bench to bedside advance our goals. Too much time and faster? energy is expended on the constant need to secure funding. And unfortunately much of the time spent on it doesn’t bear fruit.
