Kishore Challagundla

 Kishore did his Masters in Biochemistry from Bharathidasan University (India) in 1999 and was admitted into a PhD program at Lucknow University (India) where he investigated the "Role of free radical induced oxidative stress in modulation of cellular response during argemone oil intoxication" with Prof. Raj Khanna. After completion of his PhD in 2007 he joined at the Division of Infectious Diseases at the Mayo Clinic college of Medicine in Rochester, Minnesota in United States for Post Doctoral studies. Later he moved to Portland (OR) in 2009 to initiate his career in basic cancer biology at Molecular and Medical Genetics in Mushui Dai's lab at OHSU. His research interests in the lab are diverse including the regulation of p53, cMyc turn over by ribosomal proteins. In addition to this he is also exploring the biogenesis pathway of micro RNAs.

He has won several awards including best Paper Published Award in graduate school (2007), Best Poster Presentation Award at the Society for Free Radical Research Asia conference (2007) and two international Fellowships from the European Cell Death Association (ECDO) in 2006 and International Redox Network (IRN) Japan in 2005.
