Deep eutectic solvents; Ionic liquids; Light-driven nanochemistry; Nanocatalysis; Nanoparticle-based theranostics
Research in the Baker Group is highly cross-disciplinary and collaborative in nature and is motivated by problem-solving using sustainable nanoscience and task-specific solvent-engineering approaches. Examples of ongoing research projects include:
- Benign-by-design solvents (ionic liquids, deep eutectic solvents, zwitterionic liquids)
- Deep eutectic solvent media for nanochemistry
- Functional synthetic nanoclays
- Fluorescent, theranostic, catalytic, and photoacoustic nanomaterials
- Waste valorization (e.g., upcyling food waste to useful materials)
- Diversity in education
Women in Training for Science (WITS)
In partnership with Kathryn Fishman-Weaver—award-winning secondary gifted education teacher at Rock Bridge High School and Ph.D. student in Educational Leadership and Policy Analysis at the University of Missouri—we launched an outreach program in 2013 with the overarching goal of cultivating the talents of female students from the high school to graduate school level, with seminars, hands-on learning activities, laboratory experiences, supervised training, sibling proxy (“big sister”) mentorship, and internships designed to ignite and promote a lifelong interest in science and scientific careers. For general inquiries, or for those interesting in participating, please feel free to contact me at: firstname.lastname@example.org.
