August 2025

Julia gave a talk at the ACS Analytical Division Awards Symposium.

Mushfeqa gave an oral presentation and Emerson, Nazifa, Sara, Alyssa, and Raquel presented posters at Chicago Mass Spec Day on the UIC campus. 

Congratulations to Mushfeqa on recieving the Chicago Mass Spec Day Enrichment Award!

July 2025

Alyssa gave a poster presentation at the Eli Lilly Graduate Student Innovaters in Analytical Chemistry Symposium in Indianapolis.

The group visited Corteva Agriscience to see their facilities and learn about their research. Raquel, Nazifa, Mushfeqa, Sara, and Lixue all gave oral presentations of their research.

Congratulations to Murphy on graduating with her master's degree!

Ilyas presented his work at the Purdue Summer Undergraduate Research Symposium.

Julia presented a talk at the 8th Frontiers in Metal Oxide Cluster Science (FMOCS) Conference in Mainz, Germany.

 

Overview

Our research at the interface of physical and analytical chemistry is focused on the advanced development of preparative and analytical mass spectrometry for applications in materials synthesis, imaging and chemical analysis of biological systems at a subcellular level, and environmental sciences.
