Research Interests

My research focuses on understanding how spiders communicate through taste and smell. This is motivated by the need for integrated pest management options for urban spiders as arachnophobia drives the use of pesticides against harmless spiders. My work primarily involves the neurotoxin-producing widow-subfamily Latrodectinae, identifying their sex pheromone and mate-call mechanisms, as well as investigating the chemical ecology of their sexual signals. To achieve my research goals, I use  non-targeted metabolomics based on coupled high-resolution mass spectrometry-high-performance-liquid chromatography (HRMS-HPLC), as well as gas chromatography-MS (GC/MS) analyses. My prime interest lies in identifying natural semiochemicals produced by spiders or perceived by them in an attracting or deterring fashion.
