No Patient Satisfaction Reviews
Why not?

There is no publicly available rating for this medical professional for one of the following reasons:

  1. He or she is not employed by Penn Medicine.
  2. He or she does not see patients in a medical practice setting.
  3. He or she sees patients but has not yet received the minimum 30 patient satisfaction reviews in the past 12 months, ensuring that the rating is statistically reliable and a true reflection of patient satisfaction.

Description of Research Expertise:

The Axelsen laboratory is focused on the pathogenesis of Alzheimer's disease, particularly in the roles of oxidative stress and protein lipid interactions. A variety of whole-animal models and in vitro systems are used, as well as a large repository of human brain samples. The laboratory has developed novel isotope-based techniques for characterizing oxidative stress in brain using mass spectrometry and various forms of optical spectroscopy, including infrared, fluorescence, and internal reflection spectroscopy.
