Chandra’s bachelor’s degree in Chemistry included a project involving the preparation of primary, secondary and tertiary sulfinamides and characterising them mainly by nuclear magnetic resonance (but also by infrared) spectroscopy.  For his Master’s degree, his dissertation involved the synthesis of various copolymers (hydrogels) – suitable for use as contact lens materials - by means of solution polymerisation. Different ratios of hydrophilic, hydrophobic and crosslinking monomers were used as the starting materials. The optical and mechanical properties of the hydrogels were then evaluated. 

Chandra then worked as research polymer chemist in Luxembourg for the International Synthetic Rubber Company for 4 years, carrying out numerous projects on both natural and synthetic rubbers (including blending with other materials) encompassing the compounding, vulcanisation and  compression moulding of the elastomers whose properties were then tested. The work also included the processing, injection moulding and evaluation of different copolymers such as acrylonitrile-butadiene-styrene.

On returning to England, he undertook his Master’s degree in Business Systems Analysis, his dissertation being the design of a materials database and its user interface. He  was then employed in the Chemistry department of the North East Wales Institute at Deeside and undertook his postgraduate degree part-time.  After being relocated to Wrexham Plas Coch, Chandra obtained his PhD in Physical Chemistry in 1999.  His thesis involved the synthesis of a number of hydrophobically modified sodium polyacrylates and the characterisation of their solution and adsorption properties largely by rheology and electron spin resonance spectroscopy.  He has been employed at NEWI and subsequently Glyndŵr University ever since.

These include the physico-chemical characterisation of macromolecules in solution, their adsorption onto different surfaces and the corresponding effects on colloid stability.  He has also undertaken various projects involving different hydrocolloids such as alginates, carrageenans, starches, cellulosics, various gums (Arabic, xanthan, guar & locust bean etc) pectins and chitosans.  Evaluation of their attributes has been acquired by a host of techniques including various modes of spectroscopy; gel permeation chromatography and other chromatographic techniques; rheology, particle sizing, calorimetry and microscopy.
