David Winogradoff earned his B.S. in Mathematics in 2009 from Haverford College, and his PhD in Chemical Physics in 2015 from the University of Maryland, College Park under the direction of Prof. Garegin Papoian. He is currently a postdoctoral fellow working with Prof. Aleksei Aksimentiev at the Center for the Physics of Living Cells in the Physics Department at the University of Illinois, Urbana-Champaign.


He specializes in computational biophysics, including atomistic and coarse-grained molecular dynamics simulations. In particular, he focuses on modelling chromatin, detergent-induced protein unfolding, selective transport across the nuclear pore complex, viruses, and the crowded environment inside a living cell. These efforts are essential to the goal of building a complete, computational model of an entire cell. 


He also contributes to outreach efforts of the Aksimentiev group and the Center for the Physics of Living Cells, including the annual CPLC summer school and the development of an image-making tutorial (http://www.ks.uiuc.edu/Training/Workshop/Urbana2018c/tutorials/dna-nanostructure-visualization.pdf), the live demonstration of which has been viewed over 1,000 times on YouTube (https://www.youtube.com/watch?v=jySOUCZqq-M).
