Postdoctoral Scholar

In general, my lab is always looking for excellent, motivated postdoctoral scholars, who are willing to apply for internal JHU and external fellowships to fund their training. Women and underrepresented minority applicants are encouraged to apply.

Dynamic Behavior of Soft Materials

The Mechanical Engineering Department at Johns Hopkins University is seeking a postdoctoral fellow to work on a project with the Security Technologies Group in the Material Measurement Laboratory at the National Institute of Standards and Technology (NIST) in Gaithersburg, MD. This opportunity relates to the development of novel metrologies to study the dynamic response of soft, non-linear materials subjected to impacts of up to 15 m/s and 150 J. Material systems include foams, elastomers, additively-manufactured meta-material structures, and jamming fluids. Relevant applications include protection from blunt impacts that occur during sports, falls, and in the workplace. The candidate must be able to work at NIST in Gaithersburg, MD, which is the primary site of the project. The project has potential for collaborations at JHU and the University of Chicago.

The candidate will be expected to conduct experimental research on model and novel impact mitigating materials using both falling mass and mechanically-driven impact instruments; develop methods to integrate Digital Image Correlation (DIC) strain measurements with compression, shear, and combined compression/shear loading geometries and develop structure-performance relationships relevant for energy dissipation, force redirection, and energy storage. The candidate is also expected to support constitutive model development based on integration of dynamic force data and DIC strain fields. Finite element modeling expertise   is a plus, but not a requirement. The program is aligned with the Center for Hierarchical Materials Design (http://chimad.northwestern.edu/) within the Materials Genome Initiative. Successful candidates will have a PhD in engineering and be familiar with non-linear material mechanics, scientific equipment design, and mechanical test equipment.

Interested candidates should email a cover letter, CV, list of publications and list of references. Please send all materials to Professor Vicky Nguyen at vicky.nguyen@jhu.edu AND Dr. Aaron Forster at aaron.forster@nist.gov. Please put in the subject line: JHU-NIST postdoctoral application. Consideration of applications will start immediately and will continue until the position is filled. The Johns Hopkins University is an affirmative action/equal opportunity employer and welcomes applications from women and members of underrepresented groups.

Ph.D. Student

My lab is always looking for excellent, motivated Ph.D. students interested in biomechanics and polymer mechanics.  Specifically, I would like to recruit for Fall 2018 student to study the structure-properties relationship of soft tissues.

  • Please note that in the event that I receive a lot of applications, I won’t be able to reply to all applications or confirm that I have received them. Thank you.
