Prof. Dvorkin's research focuses on "data-driven" cosmology: predictions from fundamental physics which can be tested with cosmological data. Her research interests span questions related to inflation, dark matter, dark energy, and neutrinos. To assess these questions, she uses data from the Cosmic Microwave Background (CMB) and the large-scale structure (LSS) of the universe.
Prof. Dvorkin's research includes hands-on data analysis as well as theory. In the Dark Matter arena, she has led research on scenarios where dark matter couples to other particles as well as to itself, and predicted observable effects on cosmological data sets.
She has also led an analysis looking for the effects of sub-GeV dark matter particles using CMB data measured by the Planck satellite and Lyman-alpha forest data from the Sloan Digital Sky Survey. The strong constraints coming from this analysis are particularly interesting given that sub-GeV dark matter masses are complementary to those probed by current direct detection experiments. She has been actively involved in leading the science goals for the next-generation CMB experiment, CMB-S4, for which these scenarios are being proposed as the main driver of the dark matter science case.
She has developed with her research group a new formalism aimed at probing small-scale structure using gravitational lenses, by means of statistical measurements of dark matter substructure. She has proposed this as a key observable that can yield important clues about the matter distribution within the a galaxy.
In the Early Universe arena, she has pioneered a model-independent method for probing the shape of the inflationary potential, known as "Generalized Slow Roll". She has also constructed new theoretical templates for higher-order correlation functions of the initial curvature perturbations that could shed light on the physical properties of particles with non-zero spin during inflation as well as possible phase transitions during the early universe. She developed statistical tools to look for these correlation functions in the CMB and the LSS data measured by current and future surveys.
In 2014-2015, she joined the joint analysis between BICEP2, the Keck array, and Planck collaboration. She worked on the likelihood analysis of a multi-component model that included Galactic foregrounds and a possible contribution from inflationary gravity waves. The code that she wrote was made publicly, and it has been extensively used by the community. No statistically significant evidence for primordial gravitational waves and a strong evidence for galactic dust were reported in this work.
Prof. Dvorkin is currently the co-leader of the Inflation analysis group for the proposed CMB-S4 experiment.
Dvorkin has been named the "2018 Scientist of the year" by the Harvard Foundation for "Salient Contributions to Physics, Cosmology and STEM Education". She has also been awarded a Radcliffe Institute Fellowship for 2018-2019 and a Shutzer Professorship at the Radcliffe Institute for the period 2015-2019.
Professor Dvorkin, born and raised in Buenos Aires, Argentina, received her Diploma in Physics from the University of Buenos Aires with honors. She earned her Ph.D. in the Department of Physics at the University of Chicago in 2011, where she won the "Sydney Bloomenthal Fellowship for "outstanding performance in research". She has conducted postdoctoral research at the School of Natural Sciences at the Institute for Advanced Study in Princeton (from 2011 to 2014) and at the Institute for Theory and Computation at the Center for Astrophysics at Harvard University (from 2014 to 2015), where she was both a Hubble Fellow and an ITC fellow.
