Education: B.Sc.(Chemistry) Kasetsart University, Thailand.
M.Sc.(Chemistry) Freie Universitaet Berlin, Germany,
Dr. rer. nat. (Bioanalytical Chemistry), Universitaet Potsdam, Germany
Research interests: Biosensors, Bioanalysis, Bio-based materials, Biomimetic materials, Functional materials, Nanocomposites, Carbon materials

We are currently working on a diverse range of topics concerning synthesis, characterization  and applications of functional materials including

1) Bio-based materials containing bioactive plant extracts with antimicrobial, anti-inflammatory, antioxidant activity as wound dressings, scaffolds for tissue engineering and  active food packaging

2) Nanomaterials in printable electrochemical sensors, test strips and naked eyes colorimetric analysis for selective detection of food contaminants (e.g., hormones, antibiotics, pesticides, mycotoxins, foodborne pathogens) and  biomarkers in cancer, cardiovascular, immunological and infectious diseases

3) Magnetic carbon adsorbents from biomass (i.e., sugarcane bagasse, water hyacinth, oil palm shell) for waste water remediation with simple separation using an external magnet after completed decontamination process

4) Carbon based materials from biomass for sensor and energy storage

5) Moleculary imprinted polymers (MIPs) for chiral separation, selective enrichment/extraction of active compounds from natural products, environmental monitoring and waste treatment
