NIH F32 Grant for Hayden Holmlund
Fourth year DRB PhD student Hayden Holmlund received a fundable score 21 (13th percentile) for the competitive NIH F31 grant. He submitted the F31 grant to support his dissertation research aiming to identify the molecular function of the mouse Y chromosome zinc finger proteins ZFY1 and ZFY2 that he carries out in the Monika Ward Laboratory. This is the second successful grant submission of Hayden. In 2022 he applied for, and was awarded, a prestigious Chateaubriand Fellowship to spend 6 months in the laboratory of Dr. Ward's long-term collaborator from the Cochin Institute in Paris. He is there now, performing some of his dissertation experiments and enjoying fresh croissants. Bravo Hayden!

2019 DRB Program Retreat
(November 6, 2019, Wednesday, IBR Seminar Room)
The JABSOM Developmental and Reproductive Biology (DRB) Graduate Program Students 2019 Retreat took place on November 6 at the UH Manoa Institute of Biogenesis Research (IBR). Thirteen students (7 PhD and 6 MS) presented their work. The topics covered various aspects of reproductive and developmental biology, such as stem cells in reproduction, oogenesis, fertilization, assisted reproduction technologies, embryonic and fetal development, placentation and other aspects of pregnancy, transgenesis, behavior, etc. Faculty from the IBR, Anatomy, Biochemistry & Physiology (ABH) and Cell and Molecular Biology departments were in attendance. The meeting was highly successful, with collegial atmosphere and vivid discussions. The students' presentations were top-notch, both in respect to power point presentation quality and its oral delivery. See more about the Retreat, including photos of all students, in here.
