PRF funding that I have received over the past 20 years has substantially contributed to advancing the science, careers and education of five female scientists. In my early, pretenure career, PRF (2001, 2005) funding allowed me to expand my research focus, which is rooted in stable isotope analyses for paleoceanographic reconstructions, to work on foraminiferal Mg/Ca ratios as a paleothermometer and sea level proxy (Billups and Scheiderich, 2009) as well as nannofossil Sr/Ca ratios as a productivity indicator (Waite et al., 2008). Further grants in 2010 and 2016 focusing on nitrogen isotopes as a tracer for marine primary productivity (Billups et al., 2012) and amino acid racemization in paleothermometry (Millman et al., manuscript in preparation), respectively, provided continued support for my research activities. Looking back, I would like to highlight the significance of PRF funding not only on my career, but also on that of the students in my research group. These grants funded three Master’s Theses (Kathleen Scheiderich 2004, Amanda Waite 2005, Emily Millman 2019) and one post-doctoral advisee (Dr. Rebecca Hays, 2010). K. Scheiderich and A. Waite continued in PhD programs and are now researchers at the USGS, Ca, and the ANGARI Foundation, Fl, respectively. E. Millman is currently in a PhD program in St. Louis. Dr. R. Hays remained in academia accepting a tenure track position at Eastern University in 2011, where she is currently an Associate Professor. Undoubtedly, funding from the PRF has been instrumental in the professional development of these students and myself.
