Education and career

Sakai received a B.A. from Oberlin College in 1972. [1] [2] She went on to earn a master's degree [3] and a Ph.D. from the University of Michigan working on the ecology of silver maple trees. [4] Following her Ph.D., she held positions at Oakland University and the University of Chicago before moving to the University of California, Irvine [5] where she has been a professor since 2002. [3]

From 1993 until 1994 Sakai was a program officer in the Division of Environmental Biology at the National Science Foundation. [6]

Research

Sakai is known for her work on plant breeding systems and how they have evolved over time. Her research uses two plants as model systems: the genus of Schiedea where she examines dioecy and pollination and the genus Oxalis where she studies heterostyly or variations in shape. Sakai's early research examined the role of temperature in plant survival. [7] [8] She went on to examine spatial patterns in sex of silver maple trees [9] and aspen trees. [10] Sakai has examined sex expression [11] and inbreeding in Schiedea flowering plants. [12] She has also used Hawaiian plants as a model to examine dioecy, or the presentation of separate male and female plants. [13] [14] Some of the plants Sakai researches are endangered species, and she has examined the reasons for declining plant populations [15] and the population genetics of invasive species. [16] Her work includes collaborations with Stephen Weller, including the observation that pollination of Schiedea flowering plants occurs through the actions of a Hawaiian moth. [17] Her work on conservation of Schiedea kauaiensis was portrayed in a 2019 video describing how she is studying and protecting rare plants in Kaua'i, Hawaii, through her work with students, amateur botanists, and the National Tropical Botanical Garden. [18]

Sakai has defined the conditions that lead to a lack of retention of women in science [6] and has sought to broaden participation of underrepresented groups. [19] In 2011, Sakai received funding from the National Science Foundation to establish the PLANTS program (Preparing Leaders and Nurturing Tomorrow's Scientists) which aims to broaden participation of underrepresented groups in botany. [20] [21] In the period from 2011 until 2015, more than 60 students were able to use this funding to attend a botany meeting and interact with mentors in the field. [22]

Selected publications

Awards and honors

Sakai was elected a fellow of the American Association for the Advancement of Science in 2012. [23] In 2019, Sakai was named a Distinguished Fellow of the Botanical Society of America, the highest honor bestowed by the society. [19]
