About Us

The Origins Laboratory was created in 2004 at the University of Chicago as part of the Department of the Geophysical Sciences and Enrico Fermi Institute.

Our interests are closely tied to the question of origins. Which processes governed the synthesis of the elements? How did matter expelled from the successive generations of stars contribute to shape the cosmic abundances of the elements? How and when did solar system bodies such as planets, asteroids, and comets form? How did the Earth get its wet atmosphere? To address these questions, we study the natural distribution of elements and isotopes using various instruments designed for separating nuclides according to their mass.

Nicolas Dauphas

I am the conductor and the first violinist of the Origins Lab. When I joined the faculty of the University of Chicago in 2004 with a joint appointment at the Department of the Geophysical Sciences and the Enrico Fermi Institute, I immediately began a research program on questions related to our origins using naturally occurring isotope variations. My engineering degree has provided me with skills in analytical and modeling methods. This highly uncommon background for an isotope geochemist allows me to develop original strategies to solve some of the most important questions in this emerging, cross-disciplinary field. You can contact Nicolas at dauphas@uchicago.edu.

Marc-Alban Millet

Marc-Alban Millet joined the lab in May 2012 after a long trip over from New Zealand. Marc-Alban received his BSc from ENS Lyon (France) in 2004 and then undertook postgraduate studies at the Laboratoire Magmas et Volcans in Clermont-Ferrand (France). His PhD (nov. 2007) was focused on the trace element and isotopic signature (Sr-Nd-Pb) of OIB (mainly Azores and Cape Verde archipelago). While a post-doc in at Victoria University of Wellington (New Zealand), Marc-Alban switched interest to the geochemistry of non-traditional stable isotopes, especially Fe and applied it to a wide range of topics, from ocean chemistry to cosmochemistry. In his spare time, Marc-Alban enjoys running, tramping and photography. You can contact Marc-Alban at millet@uchicago.edu.

Christoph Burkhardt

Christoph joined the Origins Lab in February 2013. He received diplomas in geology and mineralogy from the University of Cologne, Germany, and did a PhD in isotope cosmo- and geochemistry at the ETH Zurich, Switzerland. His main (but not only) research interests are on the processes and timescales of the formation and evolution of the solar system and the Earth. Besides science, Christoph likes riding on boards, mountaineering, vegetarian cooking and books. You can contact Christoph at burkhardt@uchicago.edu.

Haolan Tang

Haolan graduated from USTC (University of Science and Technology of China) with a B.S. of Environmental Sciences. She joined in the Origins Lab in 2007. She is studying Fe-Ni systematics in different types of meteorites by ICP-MS to figure out the initial abundance and homogeneity of 60Fe in the early solar system. After work if you want to find her, just let her know you want to watch the soccer game or anime with someone :) Her email: cafetang@uchicago.edu.

Corliss Sio

Corliss graduated from UCLA with a B.S. in Geology. She joined the Origins Lab in Fall 2008. She is interested in high temperature isotope geochemistry and experimental petrology. Her research thesis is focus on the application of Fe and Mg isotopes to petrologic studies. She enjoys traveling and playing badminton. You can contact Corliss at ksio@uchicago.edu.

Francois Tissot

Francois received his double diploma of Engineer specialized in Hydrogeology and Master of Science in 2009 from both the ENSG (National School of Geology) in Nancy, France and the Lulea School of Technology in Lulea, Sweden. In the fall quarter of 2009, he joined the Origins Lab at the University of Chicago as graduate student, and became officially a PhD candidate in Spring 2011. His research currently focuses on uranium isotopes and their use as a tracer of paleoredox condition on earth. When samples allow, Francois enjoys theatre (acting/directing), photography, and Mel Brooks musicals. You can contact Francois at ftissot@uchicago.edu.

Junjun Zhang

Zhang completed her undergrad studies at Nanjing University and joined the Origins Lab in 2007. Her research focuses on understanding the origin and distribution of isotope anomalies in the solar system. She has developed a new method for MC-ICPMS measurement of titanium isotopic composition. This newly developed method has been successfully applied to different groups of bulk meteorites and lunar samples. The scientific questions she aims to answer include the origin of Ti isotope anomalies, what the carrier phases of Ti isotope anomalies are, and how these carrier phases were distributed and preserved during the solar system evolution.

Mark Fornace

Mark is a fourth-year undergraduate in the University of Chicago, currently finishing up his majors in Chemistry and Geophysical Sciences. He worked at the University of Maryland during the summer of 2011 and joined the Origins Lab in the fall of the same year. His research interests include computational modeling of astronomical processes, as well as using chemical theory to predict and match isotopic variations in geological materials. In his free time, Mark enjoys hiking, reading, and playing squash. You can contact Mark at mfornace@uchicago.edu.

Nicole (Xike) Nie

Nicole (Xike) received her M.S. of Geochemistry in IGGCAS (Institute of Geology and Geophysics, Chinese Academy of Sciences). Before that, she graduated from CUGB (China University of Geosciences, Beijing) with a B.S. of Geology. She joined the Origins Lab in the fall quarter of 2013, and is currently working on Fe isotope fractionation during the formation of Banded Iron Formations (BIF). Besides, lots of things like cooking, jogging and traveling make her feel great. You can contact Nicole at xike@uchicago.edu.

Nicolas Greber

Nicolas studied Earth Sciences at the University of Bern (CH) and subsequently started as PhD student, investigating different aspects of the global molybdenum isotope cycle. Throughout his Master and PhD project, he additionally worked at the Natural History Museum Bern, focusing on classifying and collecting meteorites in the desert of Oman. He finished his PhD in 2014 and joined the Origins Lab in January 2015, where he works on characterizing the stable isotope composition of the moon and CAIs. Besides working, Nicolas is a fan of all kind of racket sports, snowboarding, good food and books. You can contact him at greber@uchicago.edu.

Matous Ptacek

Matt studied geology at the University of Cambridge, graduating in June 2016 with an M.Sci. degree. His masters’ thesis concerned the dynamics of multiphase flow as applied to predicting eruptions in arc volcanic systems, with a specific focus on explaining the field and petrological observations from Soufrière Hills Volcano, Montserrat. He is now investigating changes in the oxidation state of the mantle through geological time. Beyond geology, Matt is interested in the work of Prof. Douglas Hofstadter, the philosophy of mind, & development of linguistic theory. He also likes cheese, bad films, and fine cognac.
