Pasadena, CA | Posted on November 23rd, 2011

Dr. Lewis is head of Biology and will also be responsible for site operations and oversight of pre-clinical research and drug development programs at the Madison R&D facility. Dr. Rozema is head of Chemistry and will be responsible for supervising the development and synthesis of siRNA delivery vehicles.

"Our expanded operations require senior level expertise to support our in-house R&D and strategic partnership prospects," said Dr. Christopher Anzalone, President and Chief Executive Officer of Arrowhead. "Dave Lewis and Dave Rozema have been leaders in the RNAi field and were key inventors of the DPC delivery system. We welcome them to the Arrowhead team and expect their expertise to provide useful insights across our development programs."

Dr. Lewis is a pioneer in the use of RNAi and was the first to show that siRNAs could be used to inhibit gene expression in multiple tissues of adult mammals. He is a co-inventor of DPC technology for targeted delivery of siRNA. Prior to his role as Site Head at the Madison facility, Dr. Lewis was the Program Director for RNAi at Mirus Bio Corporation, prior to its acquisition by Roche in October 2008.

Dr. Lewis received his B.S. degree in Biochemistry and Molecular Biology from the University of Wisconsin-Madison, and his Ph.D. degree in Biochemistry from Michigan State University. He went on to the Howard Hughes Medical Institute at the University of Wisconsin-Madison to perform post-doctoral studies where he developed viral and non-viral methods to modulate gene expression in animals, and discovered novel gene regulatory mechanisms involved in body patterning.

Dr. Lewis has authored 25 scientific papers and book chapters, has 19 patents, and has been awarded government-sponsored research grants totaling more than $5 million. He has given numerous invited speaking presentations at both scientific conferences and research institutions. He has served on several NIH review panels and is a lecturer in the Masters in Biotechnology Program at the University of Wisconsin-Madison.

Dr. Rozema has served as the Program Director, Delivery Chemistry at the Roche-Madison facility since 2008 where he played a lead role in the development and synthesis of siRNA delivery vehicles. Prior to that he was a Senior Scientist at Mirus Bio where he oversaw the development of nucleic acid delivery chemistries including siRNA-polymer conjugates for in vivo delivery, and the design and synthesis of plasmid delivery vehicles with emphasis on the development of new endosomolytic strategies.

Dr. Rozema received his B.A. degree in Chemistry and Math from Calvin College, Grand Rapids, Michigan, and his Ph.D. in Chemistry from the University of Wisconsin-Madison. He performed his post-doctoral studies at the University of Utah where he focused on mechanistic studies of protein farnesyltransferase. Dr. Rozema has authored more than 14 papers and has been granted 25 patents.
