Excited to share that Kumar lab alumna Haley Brown has received a Ruth L. Kirschtein F32 postdoctoral fellowship from the National Institute of General Medical Sciences (NIGMS). She is currently a postdoctoral fellow in Melissa Harrison's lab at the University of Wisconsin, Madison.
My friend Soni Lacefield @lacefieldlab.bsky.social is receiving the Ira Herskowitz Award at the Yeast Genetics Meeting this summer for her outstanding contributions to the field of yeast genetics. Be sure to be there and hear her give an awesome lecture!
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!
Kumar lab lunch at the Social Cantina. We say goodbye to PhD student Jasmine Warren (front right) and undergraduate student Lindsay Fleitman (back left). It has been wonderful having Jasmine and Lindsay in the lab and we will really miss both of them. Best of luck!
If you are heading to the GSA Yeast Genetics meeting this week be sure to see Soni Lacefield @lacefieldlab.bsky.social give a fantastic lecture and receive the Ira Herskowitz Award for her outstanding contributions to yeast research!
The 2026 Visual System Development GRC and GRS are fast approaching. Jeremy Kay, Kristen Kwan, Robert Johnston, and I have built an exciting program that we hope you will enjoy. Looking forward to seeing everyone at the meeting this summer in beautiful Maine. Register and RT!
I am very excited to share that Brittany Zaruszak is the newest PhD graduate student to join my research group. Brittany is studying how transcription factors coordinate with Polycomb Group epigenetic repressors to specify the fate of the Drosophila eye.
Starting 2026 by writing a new research paper on patterning of the Drosophila eye. And yes, I know that I have a great office...
So exciting to see this article in JCS! Thanks to the hard work from my lab members Gisela Cairo, MA Haseeb, Zach Boyce Joy, and great collaboration with Karen Schindler!
I’m excited to share that our pic of meiotic midbodies in wildtype and mos mutant oocytes made the cover @jcellsci.bsky.social! Congrats to @muhammad-haseeb.bsky.social and @giselacairobaza.bsky.social!
