Doctor of Philosophy in Public Health Sciences Program

The Ph.D. in Public Health Sciences program, offered by Chulalongkorn’s College of Public Health Sciences (CPHS), is a multidisciplinary curriculum based on scientifically based research in Herbal Sciences, Biomolecular Technology, Protein Modifications, and Traditional Medicines.

This in-house, semester-based program provides various types and durations of study to respond to students’ needs as follows:

1. Scientific researches on safety, efficacy and quality of herbal medicines

• Herbology: herbal materials authentication using botanical, chemical and molecular techniques; 
• Pharmacognostic specification of herbal materials with special reference to chemically active substances; biological activities of herbal materials; 
• Qualitative and quantitative analytical techniques in herbal sciences;
• Aromatherapy: chemistry of essential oils and their therapeutic effects; extraction and chemical characterization of essential oils;
• Traditional medicine:
  • In vitro investigation of safety, efficacy and quality of herbal remedy (examples of Herbal Sciences are plants, animals or minerals
  • Extraction, isolation or purification of natural products from medicinal plants or some microorganisms.
  • Chemistry of essential oils and their therapeutic effects.
  • Standardization of herbal drugs
  • Biological activities and underlying mechanisms of medicinal plants
  • Development of natural-based products

2. Biomolecular technology 

• High quality research in the field of molecular biology including basic knowledge in cellular and particle structures and functions of the cells; gene functions of cells, genetic materials, gene and gene functions; basic molecular biology techniques which may be used to study living organisms, using malaria as a case study model
• Biomolecular technology in infectious diseases
• In vitro cultivation and drug susceptibility test of malaria parasites
• DNA analysis and gene mutations by using molecular techniques
• Proteins analysis
• Genetic variation of organisms
• Gene diversity 

3. Protein modifications

Development of new bioconjugation techniques based on organic chemistry using some modified biomolecules for in vitro or in vivo studies.
