It is my great privilege to recognize Dr. Ye Peng as a recipient of the 2022 Mineral and Rock Physics Graduate Research Award. Ye earned her B.S. at the University of Science and Technology of China (USTC) and her Ph.D. from Florida State University, working with Dr. Mainak Mookherjee. Ye has recently moved to Rice University as the Pan Postdoctoral Associate, where she is currently collaborating with Dr. Rajdeep Dasgupta and Dr. Cin-Ty Lee. During her Ph.D., Ye assessed whether seismically observed midlithospheric discontinuity (MLD) in cratons could be explained by metasomatism. To evaluate whether mantle metasomatism or the presence of hydrous mineral phases such as amphiboles can explain the geophysical observations of MLD, the physical properties of amphiboles needed to be better constrained at conditions relevant to MLD depths. Ye has made fundamental contributions by providing better constraints on the thermoelastic and transport properties of amphiboles relevant for MLD through a range of theoretical and experimental studies. Owing to her broad interests, she also contributed to a better understanding of seismic and magnetotelluric signatures of hydrous mineral phases in subduction zone settings. —Geeth Manthilake, Laboratoire Magmas et Volcans, CNRS, Université Clermont Auvergne, Clermont-Ferrand, France

It is an honor for me to receive the 2022 Graduate Research Award from the AGU Mineral and Rock Physics section. I wish to express my deepest appreciation and gratitude to Dr. Mainak Mookherjee, my Ph.D. adviser, who encouraged me to pursue various research topics, including midlithospheric discontinuities and subduction zone systems. He also offered me excellent opportunities to explore those research questions from different perspectives, ranging from first-principles simulations to experimental approaches. He provided incredible inspiration and support throughout my graduate school journey. During my Ph.D., I was extremely fortunate to work with many outstanding individuals who encouraged and supported me. Dr. Geeth Manthilake guided me to conduct multianvil-based seismic wave velocity and electrical conductivity experiments with tremendous expertise and patience. Dr. Rajdeep Dasgupta introduced me to the field of experimental petrology and provided me with stimulating feedback on my research work. I also want to thank my lab mates: Dr. Sumudu Tennakoon, who taught me resonant ultrasound spectroscopy and continued to help me even after he left for industrial work; Dr. Abhisek Basu, who led me in Raman spectroscopy and diamond anvil cells; Dr. Suraj Bajgain, who assisted me with molecular dynamics; and Aaron Ashley, who always gave critical suggestions for revising my manuscripts. The Graduate Research Award motivates me to continue to produce better work in the future and push my abilities forward. Thanks again to AGU and the Mineral and Rock Physics section for this recognition. —Ye Peng, Florida State University, Tallahassee
