 Research Overview

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:

  • Non-equilibrium dynamic control of nanostructures
  • “Lab-on-a-nanosheet” synthetic organoclays 
  • Analytical chemistry for resource-poor settings
  • Waste valorization: from rubbish to functional carbons 

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.
