Daniele Cherniak is an American geochemist known for her work on using particle beams for geochemical analysis on small scales. She was elected a fellow of the American Geophysical Union in 2021.
Cherniak grew up in Cohoes, New York and went to Keveny Memorial Academy.[2] In 1983, Cherniak received her undergraduate degree from Union College[3] and went on to earn her Ph.D. in physics at the University at Albany, SUNY in 1990.[4] As of 2021, she is a research professor at Rensselaer Polytechnic Institute[5] and works at the Ion Beam Lab at the University at Albany.[6]
Research
Cherniak is known for her research on rock-forming minerals, specifically on atomic diffusion in these minerals.[7] She established the use of ion implantation to place lead into minerals followed by the use of Rutherford backscattering spectrometry to obtain diffusion profiles, which she first applied to measurements in apatite and zircon,[8] and has subsequently applied to other minerals.[9][10] She has also examined the diffusion of rare-earth elements,[11] tetravalent cations,[12] and oxygen[13] into zircon. Her work on argon[14] showed that the degassing of Earth is slower than expected.[15] Much of her work is collaborative projects with E. Bruce Watson.[16] In 2020, she began a project working with scientists Union College on a study of radioactive decay which will improve both disposal of nuclear waste and increase precision of dating material that is billions of years old.[17]
