Tova N. Williams is currently the Principal Investigator of The Sustainable Dye Chemistry Laboratory at NC State (Wilson College of Textiles). Her research thrust includes the design and development of environmentally benign dyes and coloration methods using traditional and non-traditional approaches. She completed her Doctor of Philosophy (Ph.D.) degree in Fiber and Polymer Science (Chemistry minor) in 2018 from North Carolina State University. Her dissertation research focused on approaches to the design of sustainable (less toxic) permanent hair dyes. She is a 2015 National Science Foundation (NSF) Graduate Research Fellow and a 2014 National Institutes of Health (NIH) Initiative for Maximizing Student Diversity Graduate Scholar. Tova is also a 2014 graduate of North Carolina State University, where she completed her Bachelor of Science (B.S.) degree in Polymer and Color Chemistry with Summa Cum Laude honors and University Scholars Program distinction. Tova is committed to K-12 science outreach and mentoring women interested in pursuing STEM careers.
