Triviality Results and the Relationship between Logical and Natural Languages
Published 2020“…We suggest that this strategy has broad application and teaches an important lesson: in theorizing about the logic of natural language, we must pay careful attention to the translation between formal languages, in which logical results are typically proved, and natural languages, which are the subject matter of semantic theory.…”

Coordinated motion planning: Reconfiguring a swarm of labeled robots with bounded stretch
Published 2021“…Problems of this type can be traced back to the classic work of Schwartz and Sharir (1983), who gave a method for deciding the existence of a coordinated motion for a set of disks between obstacles; their approach is polynomial in the complexity of the obstacles, but exponential in the number of disks. Despite a broad range of other non-trivial results for multi-object motion planning, previous work has largely focused on sequential schedules, in which one robot moves at a time, with objectives such as the number of moves; attempts to minimize the overall makespan of a coordinated parallel motion schedule (with many robots moving simultaneously) have defied all attempts at establishing the complexity in the absence of obstacles, as well as the existence of efficient approximation methods. …”

Regulation of miRNA degradation
Published 2022“…The subsequent discovery that the protein ZSWIM8 mediates TDMD, and the identification of many miRNAs that are stabilized upon loss of ZSWIM8, confirmed that this pathway broadly shapes miRNA turnover dynamics. We investigated whether other classes of small RNAs might too be regulated by this pathway, and found that loss of the Drosophila ZSWIM8 homolog, Dora, has no discernible effect on the levels of small-interfering RNAs (siRNAs). …”
