Post Status: 2 years with possible extension for year 3: Specific Purpose Contract

Research Group: Polymeric Materials & NanoComposites (PMNC) Group

Location: CRANN Institute, Main Campus

Salary: Appointment will be made on Points 2-6 of the IUA Post-Doctorate Researcher Level 2 salary scale, (€37,013-€ 42,181 per annum) at a point in line with Government pay Policy and experience.

Closing Date and Time: 12 Noon (GMT) on 31 January 2018


Polymeric  Materials and  NanoComposites  (PMNC)  group  (  at TCD led by Dr. Ramesh Babu. The mission is to provide world-class research in Polymeric Materials and separation sciences, to act as an intellectual powerhouse and a catalyst for the development  of  a  smart,  globally competitive  industry  sector  in  Ireland  and  Europe.

Overview of the Role:

An experienced researcher is required in the area of separation technologies for a European Union Funded Bio-based Industries innovation action flagship project (BBI-IA-FLAG) Agrichemwhey - An integrated biorefinery for the conversion of dairy side streams to high value bio-based chemicals. This current project mainly focuses on developing the separation/recovery process for sugars and lactic acid from fermentation process. This  project involves the scaling the separation technologies to commercial scales (TRL 7-8) working in hand-in-hand with industrial partner for  recovery of lactic acid from fermentation broths using various separation technologies e.g. membranes, ion exchange resins, chromatographic resins and other suitable technologies. 

Person Specification


The   experience candidate   must   have   a   PhD   in   a   relevant   field   such as   chemistry, Biotechnology, materials science, chemical   Engineering   or   physics   and/or   equivalent   industrial experience.

Knowledge & Experience (Essential & Desirable)

  • Evaluation of various MF/UF/NF/RO /PV membranes at the various stages of Lactic acid separation at the lab scale.
  • Evaluation of various ion-exchange resins for the removal of potential metal slats contaminants.
  • Separation of sugars from fermentation streams using membranes or ion exchange resins
  • Working knowledge of ICP-MS, GC-MS, HPLC, UV-Vis, protein, vitamin and amino acid analysis,  and other another analytical tools to determine the purity of lactic acid
  • Characterization of lactic acid purity by GC/LC-MS and enzyme assay kits
  • Scaling up lab scale procedure for pilot scale/demo scale for  large scale production of lactic acid
  • Writing papers and giving presentations on the research conducted.
  • Willing to travel to partners sites for scaling and demonstration of technologies
  • Helping with day-to-day running of the research group, training and supervising the students, procuring orders and managing the laboratories.
  • Good leadership skills with the ability to maintain excellent working relationships with both internal and external partners is also required
  • Excellent communication and written skills.
