Dr. Nizhou Han


Dr. Nizhou Han is an accomplished scientist and a talented experimentalist who is highly respected by students, postdocs, and faculty alike.  She began conducting research in our group in 2002 and has so far worked on diverse projects investigating carbonate and silica systems. Most of her studies have focused on biological mineralization, but she has also investigated silica glass dissolution for nuclear waste management and nonclassical pathways to crystal growth of calcium carbonates. 


In addition to her own projects, she makes valuable contributions to other projects in our group, including studies of the physical basis for polymorph selection, energy barriers to cation binding on self-assembled monolayers, thermodynamic/kinetics controls on mineral nucleation, mineral dissolution, and mineral surface chemistry. 


Dr. Han earned a Ph.D. in Soil Chemistry from Iowa State University in 1996 and has extensive experience as an analytical chemist. In our group, she is a lead author or co-author on numerous highly cited publications. 


Brenna Knight

Ph.D. Student

Brenna graduated from Appalachian State University in 2019 with a B.S. in Chemistry and a minor in Geology. There, she developed HPLC methods for quantifying organic pigments in NC heirloom apples. 


At Virginia Tech, Brenna is co-advised by Dr. Dove and Dr. Kevin Edgar in Sustainable Biomaterials at VT.  Her interdisciplinary Ph.D. research is focused on understanding how the organic matrix directs the timing and placement of inorganic crystals.  Using novel synthesis techniques, she is preparing and characterizing tailored biomaterials.  In experimental and computational studies, Brenna and collaborators are testing hypotheses for how functionalized polysaccharides affect the kinetics and energy barriers to calcite nucleation.
