A grant awarded to\u00a0Jonathan T. Ashby \u201909, assistant professor of chemistry, helped to support an undergraduate research stipend last summer for a Trinity College student working on Ashby\u2019s research project, and it also will support a student researcher in the summer of 2026.<\/p>\n
Ashby was awarded a\u00a0Pittcon Undergraduate Analytical Research Program (UARP)\u00a0grant from the\u00a0Society for Analytical Chemists of Pittsburgh, a nonprofit dedicated to promoting science awareness and education. The grant\u2019s objective is to promote innovative research in the field of analytical chemistry while providing an opportunity for advanced training and development of students at institutions without graduate programs in the physical sciences.<\/p>\n
Ashby\u2019s research project\u2014\u201cDevelopment of covalently binding fluorogenic dyes as labels for mass spectrometric analysis of proteinnucleic acid complexes\u201d\u2014investigates how biomolecules interact with one another by labeling their surfaces with a dye molecule called fluorescamine. Ashby explained that normal biological functions are dependent on interactions between biomolecules such as proteins, nucleic acids, and sugars, but diseases can occur when proteins misfold and clump together to form large plaques. One prominent example of this phenomenon is Alzheimer\u2019s disease, he said.<\/p>\n
\u201cOne of our big goals is to use the labeling to identify where the proteins interact with each other. This way, we could use that information to identify molecules that might inhibit the aggregation process,\u201d said Ashby. These insights could potentially be used by pharmaceutical companies to screen for therapeutics for treating certain types of diseases, he added.<\/p>\n
For eight weeks in summer 2025, neuroscience\u00a0major Ethan Andujar \u201927 worked with Ashby to identify optimal conditions for labeling proteins with fluorescamine, using fluorescence and mass spectrometry to see which amino acids in proteins can be labeled with fluorescamine, and using fluorescamine to identify binding between protein-DNA pairs that are known to interact in the body.<\/p>\n
Next summer, Ashby plans to visit UMass Amherst with a student researcher to utilize specialized mass spectrometers to study larger proteins. \u201cOne of the benefits of having the Pittcon UARP funding for summer research,\u201d he said, \u201cis that it provides students with the opportunity to use nearby instrumentation without having to interfere with their busy schedules during the semester.\u201d<\/p>\n
Working with students in the lab and supporting their development is important to Ashby because of his own experience as a Trinity student. He began doing analytical research as an undergrad working with\u00a0Janet F. Morrison, principal lecturer in chemistry, emerita.<\/p>\n
Reflecting the evolution of his own research interests toward biological analytical work as a graduate student and postdoc researcher, Ashby said that he wants to get his Trinity students thinking about the intersection of chemistry with other disciplines. He identified the interdisciplinary outlook and collegial spirit within Trinity\u2019s\u00a0Chemistry Department\u00a0as a formative influence on his interests as a scientist.<\/p>\n
\u201cOne thing that I learned early on at Trinity was, \u2018Pay it forward.\u2019 Upper-year chemistry majors would mentor students taking introductory courses, while faculty took on student research assistants in a wide variety of fields and were genuinely interested in their success,\u201d Ashby said. \u201cReturning to Trinity as a faculty member, I see that students and faculty within the department are just as committed to supporting one another as they were when I was a student, and I\u2019m delighted to be part of this cycle.\u201d<\/p>\n
