Happy to share that my graduate student Jasmine Warren successfully defended her PhD thesis today! She has put together a beautiful story on the role played by the Extradenticle (Exd) transcription factor in patterning the Drosophila compound eye. Keep an eye open for her upcoming research paper!

The retina’s rhythm Calcium waves facilitate the emergence of sight

Check out my Perspective article “The Retina’s Rhythm” which accompanies an exciting paper by Claude Desplan in Science. I highlight his discovery that waves of calcium are required to finalize the honeycomb-like structure of the Drosophila retina.

Patience is a virtue! I have been a season ticket holder at my home institution, Indiana University, for 23 years. I have seen a lot of bad football games. My perseverance through the pain and suffering is finally paying off. We are ranked #3 in the country. Upwards and onwards!
