Dan Dudek, Ph.D.

Engineered artificial proteins that mimic the elastic properties of muscles in living organisms are the subject of an article in Nature magazine released May 6th, and one of the authors is Dan Dudek, an assistant professor of engineering science and mechanics at Virginia Tech.

The work was conducted when Dr. Dudek was a postdoctoral fellow at the University of British Columbia’s Department of Zoology where he worked with the lead author Hongbin Li of the University of British Columbia’s Department of Chemistry.

The team engineered a synthetic protein to reproduce the molecular structure of titin, the muscle protein “that largely governs the elastic properties of muscle,” according to the Nature article. They tested the nanomechanical properties of the new proteins at the single-molecule level and then cross-linked them into a solid rubber-like material.

The authors wrote that synthetic biomaterials display the unique multifunctional characteristics of titin, acting like a spring with high resilience at low strain and as a shock-absorb at high strains. Dr. Dudek added that this is “a nice feat when the material at a high strain releases stress instead of tearing apart. The material’s spring-like properties are fully recoverable.”

Dr. Dudek received his Ph.D. in Integrative Biology in 2006 from the University of California at Berkeley. He earned his bachelor’s degree in Biology with honors from the University of Chicago in 1998 and was in Canada as a National Science Foundation International Research Fellow.

The other authors to this Nature article are Shanshan Lv, Yi Cao, and M. M. Balamurali, and John Gosline, all of the University of British Columbia.
