Generation and deposition of liquid fragments

Supervisors: Ahmed ISMAIL

Application Deadline: 07-09-2021

The great interest in liquid fragmentation derives from the sea of applications within the chemical and biological sciences. For instance, micro-droplets dispersed within an immiscible continuous phase can mimic conditions similar to that of a single cell, allowing ultra-high throughput experimentations to understand the biological and chemical reactions. Other applications include protein crystallization, DNA sequencing, emulsion based bias-free PCR and cell sorting assays. In manufacturing industry, the generation of micro-droplets/jets has the added advantage of printing 2D and 3D structures. Depositing micro-droplets/jets is used for manufacturing TV displays, sensors, optoelectronic devices and conductive tracks for electronics. In biotechnology industry, biopolymer liquid loaded with living cells is dispensed in form of micro-droplets to create biological structures in a layer-by-layer manner allowing for manufacturing organs substitutes. This wide range of applications has motivated scientists to develop technologies in order to generate and deposit liquid fragments in form of droplets and jets. However, there remain significant challenges understanding fundamental interfacial science and optimize the fragmentation process.

The objective of this exciting research project is to explore the underpinning physics of phenomena related to the generation and deposition of micro-droplets/jets by means of external mechanical, hydrodynamic and electrical forces and build upon this knowledge to develop new microfluidic systems to break the limitation of the currently existing technologies. Such system will be used in many applications such as inkjet printing and microencapsulation. The successful candidate will obtain world leading training in a range of disciplines during the PhD including, advanced micro fabrication, high speed visualization, and developing scaling laws and theories.


The ideal candidate should have:

  • A minimum of 2:1 undergraduate degree (or equivalent) in Physics, Engineering, or Applied Mathematics.
  • Proven experience in Fluid Dynamics.
  • Experience in a laboratory environment
  • Excellent English written and spoken communication skills

The following skills are desirable but not essential:

  • Ability to program in Labview
  • Ability to program in Matlab
  • General knowledge of electronics and optics
  • Knowledge of CFD

This opportunity is for a highly motivated person who is willing to dedicate full time to do experimental and theoretical work and has passion toward learning new things and conducting scientific research.
