    My expertise is in exploring physical, dynamic, scaled models for scientific computation, especially for biological systems at nano-scale.

    In my PhD thesis, I have pointed out a new direction of exploration with physical models for polypeptides. I have designed and fabricated Peppytides (www.peppytides.org), the first mechanically flexible, scaled, physical model of the polypeptide chain that accurately demonstrates the molecular dynamics behind protein folding such as degrees of freedom on rotatable bonds, barriers to bond rotation, bond lengths and angles, and short- and long-range (nonbonding) interactions between amino acids. Reported in PNAS here.

    Unlike most 3-D printed protein models, Peppytide features a backbone chain that can be folded or unfolded to make at-scale, all of the common protein secondary structure elements, such as alpha helices, beta sheets and turns, and small tertiary structures and protein motifs. See pictures and details of the model in Peppytides website.
