03 PhDs & 1 Postdoc: Bubble Gun/Needle-free delivery of liquid jets 1399 views

The Mesoscale Chemical Systems group at University of Twente has three PhD positions as part of the ERC Starting grant project BuBble Gun. The positions are available for 4 years and one post-doc position (2 years).

About the project:

• The needle-free delivery of liquid jets into soft and heterogeneous substrates, e.g. human tissue, has been hindered by the need to reach specific penetration depths with energy efficient means, by the break-up of jets that impedes control over the dose delivery, and by liquid splash-back after impacting the substrate that causes cross-contamination between injections.
• PhD1 – Cavitation: study of light-generated ultrafast bubble dynamics in microfluidic devices. In this project, new knowledge will be sought on energy conversion from light-source into bubble expansion and collapse inside microfluidic channels.
• PhD2 – Jetting: rheologic investigations to achieve reproducible jetting with minimal jet break-up. This project will be focused on characterization of liquid jets (diameter, length, volume, velocity, satellite droplets size distribution, etc.).
• PhD3 – Impact: investigation of liquid jet injection into soft substrates with minimal splash-back. The main objective of this project is to gain understanding on jet penetration and dispersion into skin surrogates and ex-vivo skin.

Requirements:

• Applicant must have a background in Applied Physics, Mechanical or Biomechanical Engineering, or in a closely related discipline.
• Applicant must have strong communication skills, including fluency in written and spoken English.
• Applicant must be able to work independently, and have excellent theoretical and experimental skills.
• Experience in the laboratory in any level is appreciated; but experience in microscopy, microfluidics, rheology, spectrometry, photonics and/or detection techniques will be considered as an advantage.
• Team-working skills are expected from the candidate due to the multidisciplinary and collaborative approach of the project.

Applications:

Apply online and applications should include the following documents:

• A motivation letter describing why the candidate is applying for this position, with a description of research interests (max. 1 A4).
• A detailed CV
• Academic transcripts from Bachelor’s and Master’s degrees.
• Email addresses of at least two references that are willing to send a letter of recommendation.
• An interview with a scientific presentation will be part of the interview process.
