Presently, I am working with Prof. Nick Stone in the BioSpec group of Biophysics. Employing my skills and knowledge in Surface enhaced Raman Scattering SERS plasmonic nanoparticles (NPs) for customizing and maximizing detection from within deep tissues based on spatially offset SESORS approach.

Research interests:

  • Engineering plasmonic nanostructures for use as optical sensors. Especially, nanoplasmonic enhanced optical spectroscopy including Localized Surface Plasmon Resonance LSPR, Raman SERS and Chiral Dichroism CD.
  • Point-of-care (POC) lab-on-chip diagnostics with biofluids (blood, plasma, urine etc.)
  • Deep tissue cancer diagnostics via Raman (SESORS) detection.
  • Hybrid nanoparticles.


The projects I have been involved in include:

2018- present: Working with Prof. Nick Stone at University of Exeter, UK. EPSRC Programme grants EP/R020965/1: Raman Nanotheranostics – RaNT: Developing gold-based targeted diagnostics specifically with deep tissue Raman SESORS set-up. 

2017-2018: Worked with Prof. Laura Lechuga at ICN2, Barcelona, Spain. Horizon H2020-ICT-2014-1 Project RAIS: Scalable, point-of-care and label free microarray platform for rapid detection of Sepsis. Involved in developing label-free detection of E. coli from patient blood plasma in just 30 minutes, estabilishing it as a bed-side POC diagnostics.

2015-2016: Worked with Dr. Jessica Rodriguez-Fernandez and Prof. Jochen Feldman at LMU, Munich, Germany. EU FP7 Project UNION: Ultra-versatile Nanoparticle Integration into Organized Nanoclusters. Designed plasmonic nanostructures with specific optical responses including directional assembling potential of Gold nanorods, assemblies directed via manipulating DNA, chiral responses, as well as, switchable plasmonic/SERS behaviour with semi-conductor-plasmonic NP interactions.

2014-2014: Worked with Dr. Emad Kirikaous at QUT, Brisbane, Australia. Australian Advance Queensland award: Water treatment technologies. Developed iron oxide-polymer hybrids as smart osmotic draw agents for water treatment in forward osmosis FO set-up.

2011-2014: PhD (Chemistry and Nanomaterials): Worked with A/Prof. Peter Fredericks and A/Prof. Idriss Blakey at QUT Brisbane and UQ St. Lucia, Australia. Australian Research Council Discovery Project ARC DP1094205: Multimodal Biomedical Imaging probes. Designed NP hybrids (RAFT polymer-gold nano-assemblies) based Raman imaging agents to be employed for deep tissue SESORS detection. 

2009-2011: Researcher in Industry, TAF, Thailand. Developing functional acrylic polymers and textile grade fibres.

2007-2009: Masters (Material and Fibre Science), Indian Institute of Technology (IIT) Delhi, India. Developing stimuli-responsive (thermo and pH) polymer-NP hybrids for engineering switchable surfaces.
