The Atmospheric Chemistry Laboratory hosted undergraduate researchers Leyla Salehpoor and Hossein Ghezelbash this summer for their thesis research projects in the BSc.(Hons) program in Chemistry at YorkU. These motivated undergraduates built their own instruments, collected atmospheric samples, and developed some very challenging analytical methods, which they presented and defended with vigour and enthusiasm! Congratulations to you both! Celebration of this completed research journey and birthdays for Teles and Hossein was held over sushi.
