Interests:

Structural bioinformatics, databases, mining techniques, visual analytics, protein folding and design, single-nucleotide polymorphisms, amyloid diseases, protein design, dynameomics, combined with experimental biophysical studies, diagnostic and therapeutic design for amyloid diseases.

Background:

B.A. Chemistry, Reed College, Ph.D. Pharmaceutical Chemistry, UC San Francisco, Jane Coffin Childs Postdoctoral Fellow in Structural Biology, Stanford University, 30 yrs molecular modeling and biophysical studies of proteins/peptides. Performed first molecular dynamics simulations of protein folding/unfolding, single-nucleotide polymorphisms, and conformational changes during amyloidogenesis. Dr. Daggett is on the editorial boards of Biochemistry, Structure, and Current Opinion in Structural Biology. Formerly Senior Editor: Protein Engineering, Design, and Selection. Biophysical Society Fellow, elected 2011, Fellow of the American Institute of Medical and Biological Engineering, elected 2017.

Research:

Our molecular dynamics simulations led to the discovery of a new protein structure formed early during amyloidogenesis linked to toxicity. Computational simulations and associated informatics studies progressed to experimental studies to test the computational predictions and to diagnostic and therapeutic development efforts based on the computational and informatics findings. Current research involves protein simulations, structural informatics, protein design, and associated experimental studies.
