Nathan Klein is an Assistant Professor in the Department of Computer Science at Boston University, within the College of Arts and Sciences. He previously held a postdoctoral position at the Institute for Advanced Study in the School of Mathematics and completed his PhD at the University of Washington under the supervision of Anna Karlin and Shayan Oveis Gharan.
His primary research lies in approximation algorithms, with a strong focus on graph problems such as the Traveling Salesperson Problem (TSP). He specializes in rounding techniques for linear programming relaxations, particularly randomized and iterative rounding methods. His work often targets improvements in approximation factors and integrality gaps for fundamental combinatorial optimization problems.
The recent publications highlight a consistent theme: advancing the theoretical understanding of TSP and related graph optimization problems. Key contributions include improved approximation bounds using max entropy algorithms, dual analysis techniques, and new rounding frameworks. His research bridges theoretical computer science and discrete mathematics, with applications in network design and algorithmic foundations.
