Catalina Arango Pinedo serves as Associate Professor in the Department of Biology at Saint Joseph's University, Philadelphia, where she has held faculty positions since 2010 (promoted to Associate Professor in 2016). She concurrently directs the McNulty Scholars Program, focusing her research on Sinorhizobium meliloti—a nitrogen-fixing bacterium critical for legume agriculture.
Her educational background includes:
- BA in Civil Engineering (1992), Universidad de los Andes, Bogota
- MS in Civil and Environmental Engineering (1994), Universidad de los Andes, Bogota
- PhD in Environmental Engineering (2000), University of Massachusetts, Amherst
Dr. Arango Pinedo's research centers on molecular mechanisms of bacterial symbiosis, with dual emphases on catabolite repression (a global regulatory system governing carbon/nitrogen utilization, virulence, and biofilm formation) and biofilm development in S. meliloti. Her lab investigates how biofilm formation facilitates root-hair infection in legumes and seeks to identify novel genes linking catabolite repression, biofilm dynamics, and symbiotic efficiency—aiming to enhance agricultural applications through microbial engineering.
Publication analysis reveals consistent focus on S. meliloti genetics (2003-2010), with evolving themes from plasmid transfer and biosensors (early career) to catabolite repression mechanisms and nanoparticle-biofilm interactions (recent work). Key collaborations with D.J. Gage dominate her symbiosis research, while environmental engineering roots appear in early studies on bacterial conjugation and water quality indicators.
Dr. Arango Pinedo's scientific awards were not documented in the source material.
While her laboratory leadership implies graduate student mentorship, specific advisees and research grants are unmentioned. Her McNulty Program directorship suggests administrative responsibilities beyond research.
Her laboratory investigates S. meliloti gene regulation within the Department of Biology, utilizing plant symbiosis models to explore nitrogen fixation pathways. Current work prioritizes biofilm-related gene discovery and catabolite repression-symbiosis relationships, with potential applications in sustainable agriculture.
