  • We participated in the GROW workshop to introduce 6th-8th grade girls to innovative science (click on link to see pictures of the event). The lab presented “Glow in the dark fly: lighting up cells to learn about the body.” Students looked at fly mutations and glowing body parts using GFP (green fluorescent protein) and RFP (red fluorescent protein).
  • Welcome new lab member Maria ‘Kitty’ Lawas, who joined our group as a Research Assistant/Technician!
  • Two new lab prep/fly food assistants have joined our group and Dr. Erika Geisbrecht’s group: Fawwaz Naeem and Nathan Tolle. Welcome!
  • The McDonald lab is looking for a postdoctoral fellow (“Research Associate”). Please see the Division of Biology employment page, or click Postdoc Ad, and follow the directions on the ad for details on how to apply.
  • Welcome to new undergraduate research interns Loan Trinh and Erin Feeley!


  • Jocelyn met with lab alum Pralay Majumder on her visit to her in-laws in India. He took an overnight train from Kolkata to Bhubaneswar to chat science over tea.
