Short statement from the candidate
The Geochemical Society (GS) stands as a pivotal catalyst for global collaboration among all disciplines of geochemistry. GS members engage in the study of geochemistry spanning from the mantle to the stratosphere, the Hadean to the Anthropocene, and the atomic level to the entire Earth. I would encourage the GS to go beyond the dichotomy of high- versus low-temperature geochemistry and the distinctions between applied and fundamental science. In addition to the evolving compositions of subdisciplines, GS has experienced substantial growth in membership beyond North America, presenting us with exciting new opportunities. My experience serving the International Organization Committee for Yokohama 2016 underscored the vital role of GS in bridging members from different backgrounds to foster global collaborations. I aim for the Goldschmidt conference to ensure representation from all subdisciplines, all career levels, and all demographic segments, promoting greater inclusivity by balancing online and in-person communications. I would be open to testing progressive ideas to catalyze innovative research beyond conventional boundaries and foster the next generation of geochemists while keeping the traditional values of the premier conference for Geochemistry.

Short statement from the candidate
Geochemistry is a fundamental discipline relevant to most Earth, environmental, and planetary sciences topics with practical applications to society. The Geochemical Society's members examine fundamental questions across Earth history using different tools, from fundamental field techniques to sophisticated analytical instrumentation. Geochemical studies produce current and time-integrated data that inform many current issues of our society, such as climate change, pollution, natural resources, supply of critical metals, and recycling. I am willing to run for GS Vice President to support such a vibrant bottom-up scientific society. The GS membership is truly global and I will encourage diversity, promote science dissemination, and support the community to provide objective information and improve our society.

Statement of Interest
I am writing to express my interest in serving as an early career representative on the Geochemical Society board. As a postdoctoral researcher with a diverse background in geochemistry, spanning critical metals research to planetary geochemistry, I have gained a broad range of experiences. Currently based at the University of British Columbia in Vancouver, I collaborate with the Mineral Deposits Research Unit (MDRU), a joint academic-industry research center. I am passionate about advancing geochemical research and its applications in addressing critical societal and environmental challenges, particularly in the realms of mineral resources and the transition to sustainable energy sources. In addition to my dedication to advancing the science of geochemistry, I am also committed to addressing broader issues within our community. I am acutely aware of the need for greater inclusivity and diversity in our field, and I'm eager to work with the Diversity, Equity, and Inclusion (DEI) committee to promote diversity and representation in geochemistry, addressing disparities that exist, especially in the early career stage.

If selected to serve on the GS board, I will bring my international experience, enthusiasm, and commitment to the position. Having worked at four universities in three countries, I have served on various committees, including SEG student chapters, graduate student committees, the EGU-GMPV early-career committee, and a faculty hiring council. I aim to leverage this experience, including my positive track record of fundraising and event organization, to actively contribute to the goals and initiatives of the GS. I am determined to be an approachable and responsive representative for early career geochemists, providing a platform for their concerns and ideas. I am enthusiastic about the opportunity to collaborate with fellow board members to guide the society's direction and continue its mission to foster collaborations, share knowledge, and advance innovation in the field of geochemistry. I appreciate your consideration of my nomination and the potential opportunity to serve on the Geochemical Society board.



Statement of Interest
I am so excited to join the board of directors of the Geochemical Society as an Early Career Researcher. I, Mr. Piyal Halder, am a PhD student at Lucknow-based Birbal Sahni Institute of Palaeosciences (BSIP) and working on the fluid-rock interaction in the shallow crustal basement rocks of the Koyna-Warna Seismogenic region, Maharashtra, India, and its connection with the recurring seismicity as experienced in this region for the last five decades since the impoundment of the Koyna Dam in 1962. The findings of this research will serve as the bridge between geochemistry, mineralogy and seismology and will not only be significant in the Indian context but also in light of other instances of seismicity around the globe such as SAFOD (USA), Nojima fault (Japan), Chelungpu fault (Taiwan) etc., where a potential role of fluid-rock interaction on seismicity has been identified. As a doctoral student in geochemistry and tectonics, I am always interested in being involved with the organisations and societies that encourage and promote scientific activities in the relevant domains of the Earth Sciences. The Geochemical Society is such a nonprofit scientific organisation founded to encourage the application of chemistry to solve problems in geology and cosmology. Besides, being a member of the Geochemical Society, U.S., I am also involved with the European Association of Geochemistry, International Association of Geochemistry, and International Association for Structural Geology & Tectonics (IUGS Commission on Tectonics and Structural Geology, formerly known as TecTask). I am also an active member of the Early Career Researcher Committee of the Geochemistry, Mineralogy, Petrology, and Volcanology Division (GMPV) in the European Geosciences Union (EGU) and serving there as a Blog Editor. Recently, as a member of the TERPRO Commission of INQUA (International Association for Quaternary Research), I also took part in the ECR election of the commission. I have also become a member of the International Association for Promoting Geoethics (IAPG, affiliated with IUGS) and the Breakthrough Science Society which promote scientific awareness among the people. I am also associated with the activities of the Association of Quaternary Researchers (AOQR), India and express my views on several recent issues on quaternary geochemistry and tectonics in the association's newsletter Quaternary Chronicles.

Vision & Mission: As an ECR member of the Geochemical Society, I would like to utilize the experience gained during my involvement with different societies or bodies. I believe that I can work for the advancement of this society and can be able to raise my voice on several issues faced by the ECRs in the scientific community. My utmost priority will be to bridge the gap between the ECRs and other committees of the Geochemical Society. As I have been well versed in volunteering in workshops or conferences since my graduation period, such managerial skills will be extremely helpful during the Goldschmidt conference. If get elected, I shall try to start a blog with the permission of the other members, dedicated particularly to the young scientific community. The GS blogs will not only help in the promotion of novel findings in the field of Geochemistry but also represent several socio-economic issues faced by the young scientific community during their PhD period. I feel, such a platform is highly needed for the organisations like Geochemical Society. However, the blog will not replace the existing social media platforms of the Society, rather the interesting blogs will be posted on the social sites to attract more audience. In fact, the social media platforms will be used to call a greater number of people irrespective of gender, religion, ethnicity, or nationality, to share their views or ideas on the blogs. So, as an ECR member, I am also flexible in handling social media platforms. Thus, as an ECR member, I shall try to make society more social and open to the larger community.

Statement of Interest
My name is Manuel (Manny) R. Vejar, and I am a Ph.D. candidate at the University of Notre Dame (Indiana, USA). Environmental geochemistry is the field that sparked the engine that drives my professional pursuits when I was just a community college student. Briefly, I received my Bachelor of Science in Geology from Cal Poly Pomona (CA, USA), after transferring from Santiago Canyon College (CA, USA). While an undergraduate, I participated in 2 Research Experience(s) for Undergraduates (REUs). I conducted research in environmental geochemistry of iron oxides and their uptake of metal contaminants at Chapman University in 2016, and later in sedimentary geology of California at Stanford University in 2018. I have also conducted research using X-ray absorption spectroscopy; first studying arsenic speciation in mine tailings as an undergrad (2017-2019), and in graduate school studying plutonium redox and speciation behavior at the mineral-water interface of aluminum-doped iron oxides (2019-present).

During graduate school, I had the privilege of collaborating with international and diverse teams of world-class scientists at home (Notre Dame) and at scientific institutes abroad, like the Institute of Research Ecology at the Helmholtz-Zentrum Dresden-Rossendorf (Dresden, Germany). This institute manages an experimental station that specializes on radioactive materials at the European Synchrotron Research Facility (Grenoble, France), where I have also collaborated with incredible people who mentored me to materialize our research ideas, and explore emerging analytical techniques in geochemistry. The unique strengths and experiences of each person, and the rich diversity of these teams are what makes all of them excel in their bold pursuits. As a geoscientist with intersecting identities, I have the drive to work towards expanding inclusivity and diversity within the geosciences. At Notre Dame, I partnered with 2 fellow PhD students to co-write a proposal that was ultimately funded by the Center for Social Concerns at the University of Notre Dame to start a research experience program where we mentored 2 local high school students during the 2022 calendar year (March-December) and introduced them to scientific research. I have also participated in multiple panels and workshops that serve to educate undergraduates on conducting research and graduate programs. I wish to serve on the Executive Board to expand on this mission of helping make geosciences more inclusive and accessible.

More concretely, I would like to work with the Executive Board to find ways to:

  • Make the Goldschmidt conference more accessible to low-income and/or members of underserved communities (e.g., support for supplies like on-site poster printing for selected applicants, updating grant awards to cover increasing travel costs).
  • Help the growth of inclusivity/participation programming within and outside of Goldschmidt.
    For example, more workshops geared towards increasing diversity in geosciences, fostering equity and fair representation of oral session presenters (early career, gender, race, etc.), facilitating/fostering partnerships with undergraduate-serving institutions and high schools, networking events for early-career and pivoting researchers.
  • Increase access to advanced analytical techniques (e.g., synchrotron techniques) for early career geoscientists and scientists from institutions with fewer resources (e.g., minority-serving institutions and underrepresented countries).
  • Help make the scientific writing and publishing processes more accessible through workshops and other resources.
