Wenqin Ni, PhD (she/her/hers)

Senior Principal Scientist
Pfizer
Andover, Massachusetts

I am Wenqin Ni, Ph.D, a senior principal scientist in Pfizer. Currently, I lead multiple analytical programs from early stage (before clinical study) to commercial approval. My expertise is focusing on analytical strategies such as process characterization and comparability studies. I successfully developed comparability strategies for multiple programs to support clinical or commercial material usage after manufacturing process changes. In addition, I am a key lead/member of analytical comparability expert group in Pfizer to review analytical comparability strategy for biologics. Before joining Pfizer, I received a Ph.D degree in Northeastern University focusing on characterization of post-translational modifications in biologics using LC/MS.
