McLean Research Group Announcements

Congratulations to Amelia Taylor and co-authors on their recent publication!


“Targeted and Untargeted Mass Spectrometry Reveals the Impact of High-Fat Diet on Peripheral Amino Acid Regulation in a Mouse Model of Alzheimer’s Disease” AL Taylor, DE Davis, SG Codreanu, FE Harrison, SD Sherrod, JA McLean; Journal of Proteome Research 20(9), 4405-4414 (2021).

Amelia Taylor is an undergraduate researcher in the group and her first-author publication focuses on finding dysregulated metabolites in an Alzheimer’s mouse model.


Prof. McLean elected as a Fellow of the National Academy of Inventors for 2021


From the NAI press announcement:

“The NAI Fellows Program highlights academic inventors who have demonstrated a spirit of innovation in creating or facilitating outstanding inventions that have made a tangible impact on the quality of life, economic development, and the welfare of society. Election to NAI Fellow is the highest professional distinction accorded solely to academic inventors.”
