Generalized double and triple spherical Bessel function integrals to singular cases where the integral diverges but the result can be expressed as Dirac delta functions and their derivatives.
Meigs & Slepian, On a General Method for Resolving Integrals of Multiple Spherical Bessel Functions Against Power Laws into Distributions, in submission.
Worked with the group 2020-2021 on various projects during Philcox's PhD. Several of the papers he co-authored with our group became thesis chapters (ch. 16, 17, and 18). His initial work on parity violation also stems from his work with our group. Now post-doc at Simons Foundation/Columbia and assistant professor at Stanford.

We collaborated on a large number of projects, ranging from the ENCORE NPCF algorithm, which used work by ZS and Bob Cahn on isotropic basis functions to extend the 3PCF algorithm of ZS and Daniel Eisenstein, to novel studies of data with this code, to integral identities for spherical Bessel functions, to a new approach to spherical collapse and Kepler's equation.
