Kristian Doyle earned his PhD from Oregon Health & Science University in 2007 developing novel therapeutics for stroke in the laboratory of Dr Mary Stenzel-Poore. Dr Doyle then trained as a Postdoctoral Scholar at Stanford University under the mentorship of Dr Marion Buckwalter researching the role of TGFbeta signaling after stroke and developing a model of post stroke dementia. Dr Doyle started as an Assistant Professor at the University of Arizona in 2013. Dr Doyle was awarded an American Federation of Aging Research Fellowship in 2009, an Anita Roberts Young Scientist Scholarship in 2010, and a K99/R00 faculty transition award from the National Institute of Nursing Research in 2012.
