Miguel Tam, PhD
Senior Manager, Product Realization and Marketing

Miguel defended his PhD thesis in Gothenburg University, Sweden, where he conducted research on Dendritic Cells and bacterial infections. Postdoctoral studies followed at UCSD, still working on Dendritic Cells, but this time focused on viral infections and Inflammatory Bowel Disease. Miguel started at BioLegend in August 2012 as a Technical Service Scientist and helping with marketing projects. One of his favorite hobbies is photography, which he has recently re-taken after a break. He also likes drawing, but that has been on an even longer break (with no signs of recovery). September 2011 was not a good time, when R.E.M. decided to disband. Luckily, Bob Dylan can’t split from himself (although some people may argue he tried...).
