Lorraine Lisiecki is an American paleoclimatologist. She is an assistant professor in the Department of Earth Sciences at the University of California, Santa Barbara.[1] She has proposed a new analysis of the 100,000-year problem in the Milankovitch theory of climate change.[2] She also created the analytical software behind the LR04,[3] a "standard representation of the climate history of the last five million years".[4]

Education

Lisiecki received her S.B. in Earth, Atmospheric, and Planetary Science in 1999 and also obtained an S.M. in Geosystems in 2000 from the Massachusetts Institute of Technology. She also earned a S.M. and Ph.D. in Geological Sciences, both from Brown University in 2003 and 2005. Lisiecki's Ph.D. thesis was titled “Paleoclimate time series: New alignment and compositing techniques, a 5.3-Myr benthic δ18O stack, and analysis of Pliocene-Pleistocene climate transitions”.[5]

Research Interests

Lisiecki's current research focuses on paleoclimatology. Lisiecki's research interest in paleoclimatology arose from the lack of research and current understanding of the glacial cycles. Lisiecki uses various computational and mathematical methods to interpret and compare different paleoclimate records.[6] In specific, she is interested in the evolution of the Plio-Pleistocene climate due to its relation to the Milankovitch forcing, 100-kyr glacial cycles, the carbon cycle, and deep-ocean circulation. Currently, Lisiecki designs and develops software for rendering age models and stratigraphy.[5][7] Currently, Lisiecki is creating 3D models of ocean circulation to determine the relationship between orbital forcing and ocean circulation patterns and account for time-variant uncertainties.[6]

Contributions

HMM-Match [Lin et al, 2014]

Software for probabilistic (Bayesian) sequence alignment of stratigraphic records.[8]

Match & Autocomp Software [Lisiecki and Lisiecki, 2002]

Software designed to find the optimal alignment of two paleoclimate signals using penalty functions to constrain the rate of accumulation for sediments.[9]

LR04 Benthic Stack [Lisiecki and Raymo, 2005]

Created the LR04 stack: demonstrates an average of 57 globally distributed Benthic δ18O records collected from scientific literature, which measure ice volume and deep oocean temperature.[10]
