  • PI’s: Vicky Nguyen, Johns Hopkins University and Aaron Forster, NIST

    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 and an understanding of biomechanics of injury 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.

  • PI’s: KT Ramesh, Johns Hopkins University

    A new postdoctoral fellow position is available within the Hopkins Extreme Materials Institute (hemi.jhu.edu) at Johns Hopkins University.  The position is in the area of hypervelocity impact experiments on quasi-brittle materials, including geophysical materials, ceramics and concrete. The associated projects, funded by NASA and DoD, are focused on mechanism-based model development for impact cratering and fragmentation, and involve significant experimental methods development for high-speed diagnostics.

    The primary experiments will be performed at the new HyFIRE facility at Johns Hopkins, which is able to achieve impact velocities of 7 km/s in an environment with rich diagnostics, including flash X-ray, ultra-high-speed optical visualization, photon doppler velocimetry, and high-speed spectral imaging. The integration of data science approaches into data acquisition and analysis will be a major effort within the facility.

    The potential candidate should have a Ph.D. in mechanics, geophysics, planetary science, materials science, or physics. A willingness to work with modelers performing large-scale impact simulations is expected. An interest in data science and machine learning is a plus.

    Qualifications: The potential candidate should have a Ph.D. in mechanics, geophysics, planetary science, materials science, or physics. A willingness to work with modelers performing large-scale impact simulations is expected. An interest in data science and machine learning is a plus.

    How to apply: If you are interested, please send an email to ramesh@jhu.edu with a single PDF file containing your curriculum vitae, the names of at least two references, and a brief (less than 1 page) research statement. Please use the subject line: “HEMI Postdoctoral Fellow in Hypervelocity Impact.” Review of applications will begin April 15, but we will continue to accept applications until the position is filled. 

  • Navigation and Locomotor Control in Augmented Reality
    PI’s: Noah Cowan & James Knierim, Johns Hopkins University

    The Cowan and Knierim laboratories have multiple funded projects from NIH and DOD investigating the neural computations that underlie navigation in the physical world. We are using a novel augmented reality apparatus and multi-electrode neural recordings of place cells, grid cells, head direction cells, and other cell types of the hippocampus and related brain regions to reverse engineer the interplay between navigation and locomotor control in freely behaving animals (see https://limbs.lcsr.jhu.edu/ and http://sites.krieger.jhu.edu/knierim-lab/ ). We are seeking dynamic and ambitious postdoctoral candidates who are highly skilled in experimental research in potentially diverse areas (e.g. biomechanics, neuroscience, robotics, control systems, or physics). The ideal candidate will also have a strong computational background (e.g. dynamical systems, information theory, control theory) and/or strong data analysis skills (e.g. statistical methods, data mining, Bayesian filtering, spectral analysis, machine learning).

    Qualifications: PhD in Engineering, Neuroscience, Biology, Physics, Computer Science, or related fields. Strong computational and experimental background a must.

    How to apply: Interested applicants should send a single PDF including a brief (1 page) cover letter, CV (no more than 4 pages, including a list of 3 references), and up to two papers to ncowan@jhu.edu 

  • Postdoctoral positions are available to join a cutting-edge research project conducted by an interdisciplinary research team situated in the Institute for NanoBioTechnology (INBT) and School of Medicine at the Johns Hopkins University. The project focuses on developing novel technologies for detection of infectious pathogens and determination of antibiotic susceptibility. The fellows will be responsible for developing self-sustained microfluidic cartridges and instrument for PCR or digital PCR-based bacterial detection and antibiotic susceptibility testing (AST), aiming at addressing the challenge of multi-drug resistance or “superbugs”.  For related work of our laboratories and the project of the positions, please see Analytical Chemistry 89: 11529-11536 (2017); Scientific Reports 8(1):9793 (2018); Science Advances 4: eaat6459 (2018).

    We seek highly motivated, enthusiastic individuals who have a Ph.D. degree with less than 2 years of postdoctoral experience in the areas of microfluidics, bio-instrumentation, infectious diseases diagnostics, or related fields. Experiences with developing PCR cartridges, reagent storage, optical-thermal instrument are highly desired.
