Dr. O’Keefe has spent the past twenty years studying and writing about developmental biology, cancer biology, and neuroscience. He has published numerous articles in prestigious journals and authored grants that have been funded by both public and private agencies. Since 2010 he has worked full time as an editor and writer, helping scientists reach a global audience, regardless of their nationality or upbringing.
