Irene Duba


Graduate Fellow, David Rockefeller Graduate Program

B.A. Physics, Lewis & Clark College, 2017

Irene is interested in applying her background in cellular biophysics and microscopy to questions of chromatin structure. She is currently using ATAC-seq and fluorescence microscopy to study the chromatin landscape of cancer cells that have exited the cell cycle.


Nicole Pagane


Research Assistant, The Rockefeller University

B.A. Biophysics, Johns Hopkins University, 2019

Nicole is interested in modeling and data analysis, especially within the realm of chromatin dynamics. She helps streamline lab software for data processing and analysis and is working on a worm-like chain model of DNA to simulate local chromatin geometries.
