She studies the evolution of atmospheric levels and the impacts on, the, and, and ocean acidity. Contents.Early life and education Born in Texas, Tripati moved to California at age three with her parents, who had emigrated to the United States from the. She was raised largely by her mother, a nurse, whom she credits with giving her the support and access to opportunities that have since ensured her success. Tripati went to elementary school and junior high school in the. At age 12 she enrolled at as a full-time student through their.Tripati holds a B.S. In Geology from where she received several awards, including the Aaron Waters Award for outstanding senior in 1996. She received her.
In from the in 2002 where she worked under the supervision of doctoral advisor.Tripati began her postdoctoral research at the with a. Over the next eight years as an independent researcher, Tripati received several fellowships: the Comer Abrupt Climate Change Fellowship, the Thomas Neville Research Fellowship in Natural Science at Magdalene College, and a UK National Environmental Research Council (NERC) Fellowship.Career and Research.
Aradhna Tripati and a group of community college students in one of her research laboratories.In 2009, Tripati became an Assistant Professor at UCLA and was subsequently promoted to Associate Professor in 2014, where she continues to teach full-time. She has joint appointments in the Atmospheric & Oceanic Sciences and Earth, Planetary, & Space Sciences departments and the Institutes of Geophysics & Planetary Physics and Environment & Sustainability.Since she was an undergraduate student, Tripati has been working on advancing and utilizing state-of-the-art geochemical methods to understand Earth's climate evolution. Over the course of her career, she has applied these methods to better understand the history and patterns of changes in Earth’s temperature, carbon cycling, pH, ice volume, and hydrology.Tripati's laboratory leverages as a tool to reconstruct climate norms from the distant past in order to understand the dynamics of over a range of timescales. The primary geochemical method she works with is clumped isotope, which has led to advancements of its use in the field.

She helped develop a technique known as a ',' which allows scientists to measure past temperatures by analyzing the chemical ratios of specimens from different time periods. The chemical composition of a particular specimen reflects the composition of the Earth's atmosphere at a given point in time, allowing scientists to understand what the atmosphere was like in the past. Using these techniques in a 2009 study, Tripati and her team were able to find that the last time carbon dioxide levels reached their current level was between 10 and 15 million years ago when the average global temperature was 10˚F warmer than it is today. In a later study published in 2016, Tripati and her colleagues from around the world demonstrated that an ice sheet collapse that took place 14,000 years ago caused the Earth's entire jet stream to shift within a single century.
Their results were based on analysis of an drill core that was extracted near the U.S. Antarctic base. The study suggested that the Antarctic ice sheet may be sensitive to atmospheric carbon dioxide levels that are not far from where they currently reside.Tripati has also applied her expertise in clumped isotope geochemistry towards determining the body temperatures of that have long been extinct.

As a visiting professor at, she collaborated on a 2011 study that analyzed the composition of fossilized teeth of Jurassic to find that their internal body temperature was close to that of most modern mammals, resting somewhere between 36 and 38˚C. Scientists had previously hypothesized that sauropod body temperature was warmer, but their study suggested that these dinosaurs stayed cool by using internal air sacs for ventilation. In a later 2015 study, she and her colleagues analyzed the chemical composition of ancient eggshells to estimate the maternal body temperature of a number of different dinosaurs. Their results, combined with other studies, suggested that dinosaurs aren't simply cold-blooded or warm-blooded, but were somewhere in between.In 2014, Tripati received a to leverage as a tool to reconstruct terrestrial climates during the, as well as to support her work recruiting and retaining a diverse research workforce. Diversity, equity, and inclusion Tripati engages in activism to promote diversity, equity, and inclusion in the sciences and in the workforce, with a particular focus on addressing the underrepresentation of women, people of color, and other minorities in geoscience, environmental science, and other STEM fields.
In July 2017, she launched the UCLA Center for Diverse Leadership in Science, which focuses on the intersection between race. The Center aims to develop a cohort of community-minded scientists with expertise in climate, environmental science, green chemistry, and green engineering who will become leaders.Tripati organized and wrote a that funded a career development workshop for women and minorities at American Geophysical Union (AGU) and served as faculty lead for a program aimed at increasing transfers from to UCLA. She is involved in the Minorities Striving and Pursuing Higher Education Degrees in Earth System Science group, was a Goldschmidt Geochemistry Society Mentor, is on the advisory board for, and has established two peer mentoring groups on: Equity and Inclusion in Geoscience and Environmental Science, and the Society for Difficult Women.Tripati engages youth in the sciences with K-12 outreach programs. She works with high school students and teachers on research projects and she implements an annual project in her UCLA general education oceanography class where students must create educational content for K-12 science teachers. She appeared in a sketch on that discussed the consensus on arising from emissions and in an interview on 's Press Play with to answer questions about the realities of climate change. Awards & Honors Tripati has been awarded for her contributions to research, teaching, and service, including the, the highest honor bestowed by the United States Government on science and engineering professionals in the early stages of their research careers.
