Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism
Geophysical Monograph Series, Page 83-102., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The preparation of several 1,2,3,4,5-functionalized cyclopentane derivatives
Beilstein Journal of Organic Chemistry, 2013 With the goal of eventually synthesizing [5]radialene (3), the still missing member of the parent radialene hydrocarbons, we have prepared the pentaacetates 21 and 31, the pentabromide 29 and the hexabromide 32.

(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications
Angewandte Chemie, EarlyView.In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

Angewandte Chemie, Volume 138, Issue 7, 9 February 2026.This work demonstrates a double desymmetrization of meso‐dicarboxylic acids with symmetrical olefins, constructing complex chiral lactones with six stereocenters in one step. Unexpectedly, the halide bond was found to be crucial in achieving high stereoselectivity.
