Tessa defended her thesis on Friday, entitled "Mesendoderm patterning by Vg1/Nodal heterodimers". After she delivered her public presentation, Tessa's committee members - Doug Melton, Cliff Tabin and Craig Hunter - grilled her on her thesis, and then signed the papers. She passed! The Schier lab constructed a delightful celebratory hat.
Congratulations Tessa!
