Associate Research Scientist Position in Microfluidic-related In-Vitro Diagnosis of Infectious Disease

The Johns Hopkins University Department of Mechanical Engineering is seeking an Associate Research Scientist who is highly motivated and independent to join the BioMEMS and Single Molecule Dynamics Lab. The Associate Research Scientist is primarily responsible for leading scientific research and technology development related to microfluidic-based in vitro diagnosis of infectious diseases.


  • Lead and participate in self-initiated and assigned research projects with minimal supervision across a wide spectrum of human diseases (including drug-resistant bacterial and fungal infections, sexually transmitted infections, wound infections, sepsis, and HIV) and animal diseases (including zoonotic influenza, emerging coronaviruses, African swine fever, brucellosis), and publish results in peer-reviewed international journals
  • Mentor graduate and undergraduate students to design, perform, and troubleshoot experiments at a high standard of excellence
  • Advance technologies beyond the research laboratory setting, such as clinical microbiology laboratory use, commercialization and spin-off, and FDA EUA/510K submissions
  • Lead and contribute to grant proposals for US government agencies such as NIH and USDA
  • Establish and enforce standard operating procedures for ensuring laboratory standards and safety at the BSL-2 standard

Minimum Qualifications

  • Ph.D. in microbiology, infectious diseases, or related field with a strong track record in the in-vitro diagnosis of human and/or animal infectious diseases
  • 5+ years of postdoctoral research experiences with experiences in working and managing BSL-2 laboratories
    • Experienced in developing nucleic acid testing assays (e.g., PCR, digital PCR, LAMP, RPA, and CRISPR), immunoassays (e.g., ELISA and immuo-PCR), or microbiological assays (e.g., antimicrobial susceptibility testing)
  • Experienced in developing and testing various microfluidic devices (e.g., cleanroom microfabrication, laser cutting, thermoforming, 3D printing, and microscopy)
  • Strong written and verbal communication skills to present and publish research at international conferences and peer-reviewed international journals, as well as excellent interpersonal skills to effectively interact with peers and associates within and outside the lab

Postdoctoral Positions in Point-of-Care Diagnostic and Self-Testing Technologies

Postdoctoral positions are available to join two NIH-sponsored cutting-edge research projects conducted by an interdisciplinary research team situated in the Biomedical Engineering Department (BME) and the Institute for NanoBioTechnology (INBT) at the Johns Hopkins University. The first project focuses on developing novel point-of-care diagnostic platforms for the detection of infectious pathogens and the determination of antibiotic susceptibility. The second project focuses on the development of a magnetofluidics-based platform amenable to HIV viral load self-testing.  The fellows will be responsible for developing self-sustained microfluidic cartridges and instruments for PCR or digital PCR-based bacterial detection and antibiotic susceptibility testing (AST), and microdevices for plasma separation from finger-stick blood for HIV viral self-testing.

We seek highly motivated, enthusiastic individuals who have a Ph.D. degree with less than 2 years of postdoctoral experience in the areas of bio-instrumentation, point-of-care diagnostics, or related fields. Experiences with developing PCR cartridges, reagent lyophilization and storage, membrane-based blood plasma separation, and optical-thermal instruments are highly desired.
