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.
Chantell Balaan is featured in the Garden Island (TGI)
Chantell Balaan, a PhD candidate (Mentor: Dr. Masato Yoshizawa), is on a mission to understand how the gut microbiome affects brain function and human behavior, particularly in people with autism spectrum disorder. Her story is featured in the Garden Island, Kauai's newspaper. Read more.
Brent Fujimoto presents at American Association of Diabetes Meeting
Brent Fujimoto, Ph.D. candidate in Developmental and Reproductive Biology, presented at the American Diabetes Association Meeting in San Francisco, CA. Mr. Fujimoto mentors are Drs. Noemi Polgar and Ben Fogelgren. The research focuses on how glucose is transported into muscle which is important for understanding diabetes.
Chantell Balaan receives the ARCS 2019 Award in Medicine
Chantell Balaan, a PhD candidate (Mentor: Dr. Masato Yoshizawa), receives the ARCS Award in Medicine. The ARCS foundation (Achievement Rewards for College Scientists) is a non-profit organization administered by a group of women, who provide scholarships and awards to support graduate and undergraduate students in science. Chantell will present her research on April 13 at UH Manoa to the ARCS members, and receives the award at the ceremony on May 6.
