Unique Biology Dissertation Topics With Research Aims

Topic 1: The role of microbiome engineering in reducing antibiotic resistance

Research Aim: This study aims to explore how altering or enhancing human gut bacteria through microbiome engineering can help fight antibiotic resistance. By adjusting the natural balance of microbes, the research will look at safe ways to reduce harmful bacteria while boosting beneficial ones to improve long-term health.

Research Aim: This research seeks to investigate how changes in global temperature and rainfall patterns influence the spread of mosquito-borne diseases such as malaria and dengue. The goal is to understand how climate change alters habitats of disease-carrying mosquitoes, and how this information can help predict and prevent future outbreaks.

Research Aim: This project aims to analyse how synthetic biology techniques can be used to develop eco-friendly, biodegradable plastics by using engineered microbes. The research will focus on finding safer, sustainable alternatives to petroleum-based plastics, reducing environmental waste, and contributing to a circular economy that supports both industry and ecology.
