معرفی
Rebecca Jockusch is an Associate Professor in the Department of Chemistry at the University of Toronto. Her research focuses on using mass spectrometry and optical spectroscopy to investigate biological molecules in controlled gas-phase environments. By combining Fourier-transform ion-cyclotron resonance (FT-ICR) mass spectrometry with fluorescence and FRET techniques, her lab explores intrinsic properties of biomolecules and their interactions with solvents or binding partners.
Key instrumentation includes a 7T FT-ICR MS and a modified quadrupole ion trap (Esquire 3000+). Research themes include gas-phase hydrogen-deuterium exchange (HDX), fluorescence resonance energy transfer (FRET), and intrinsic photophysics of chromophores. Recent student achievements include PhD defenses by Neena Eappen, Cynthia Suarez, and Iden Djavani-Tabrizi, along with Haley’s Master’s work on acriflavine ions.
Lab facilities feature advanced optical systems like EM-CCD cameras and femtosecond lasers, enabling time-resolved fluorescence measurements. The lab actively seeks graduate and undergraduate students interested in biomolecular analysis under gas-phase conditions.
