TitleSpatial distribution of Hippocampus kuda and H. comes in Singapore

Synopsis:  Two species of seahorses have been observed off the islands and coastline of Singapore- the yellow seahorse Hippocampus kuda and the tiger-tailed seahorse H. comes. From anecdotal reports, H. kuda is thought to be an estuarine species while H. comes has only been found on coral reefs in Singapore. This project would assess if the two seahorse species in Singapore demonstrates habitat diversification. Habitat data will be collected through a combination of fieldwork and meta-data extraction from seahorse photographs shot in Singapore that are available online. The student will learn how to identify the common seahorse species found in Southeast Asia, confirm seahorse sightings in Singapore, and report all seahorse sightings to

No work on live or dead seahorses is involved. Looking for 2 – 3 students.

Title: Photonics – Investigation of sol-gel thin films to produce optical waveguides with high refractive index

Synopsis: The sol-gel technique presents a simple, low temperature method to produce optical waveguides that has properties such as homogeneity, porosity and film thickness that can be easily tailored to suit various applications. Such sol-gel thin films allow materials with high refractive indices to be fabricated. Spin-coating will be used in this project to exploit the low-cost, low temperature and low pressure advantages of such a process.
Students will get to learn polymer science, advanced optics topics, and understand the working principles as well as the analysis of data from common characterisation equipment such as FTIR or XRD. Students will get an opportunity to experience first-hand how scientists in the semiconductor physics field work inside a cleanroom.

Title: Current and historical distribution of palms in Singapore

Synopsis: This projects aims to list, map and determine the species of palms that have ever existed in Singapore by studying herbarium specimens in Singapore Botanic Gardens, mapping palms on the Singapore map using historical data from herbarium specimens as well as through fieldtrips to study the current distribution of palms in the nature reserves. This thorough investigation will give us a clearer understanding of the actual number of Singapore palm species, their distribution and how habitat loss has affected species numbers over a century and more.

Principal Investigator: Dr Adrian Loo (RSI)

Pre-requisites: Students need to be able to commit to this project for 6 months starting from June. A bulk of the work will be done during the June holidays


Code: B002
Title: Marine biology – Symbiotic algae in corals, implications for climate change?

Synopsis: Although corals are capable of obtaining food on their own, their survival and growth has been shown to depend largely on the nutrition derived from their unicellular algal symbiont, zooxanthellae. It has been found that different species of hard corals can host different clades of zooxanthellae and in this study, you will be required to identify the zooxanthellae using molecular methods. Methods used include using a denaturing gradient gel electrophoresis (don’t worry, training will be provided). All these would have implications for coral growth in the changing climate system. These projects are done in collaboration with Marine Biology Laboratory and/or Tropical Marine Science Institute of the National University of Singapore.

Principal Investigator: Dr Abigayle Ng (RSI) & Ms Jani Tanzil (SMART)

Pre-requisites: Committed and independent students only. Must have an interest in biodiversity and conservation.
You will be selected individually and may be paired up with another student.

Title: A comparative study of plant galls and their etiological agents found in Singapore forests and parklands

Synopsis: Plant galls are abnormal outgrowths of plant tissues and can be caused by various agents, from bacteria, parasitic plants, fungi, mites to insects such as thrips, midges, jumping plant lice (psyllids), lepidopterans and wasps. The galls are highly organized structures which come in an astounding array of colours, shapes and sizes, which can often be correlated with the etiological agent. This study will investigate the relationships among the host, gall type and etiological agent.

Principal Investigator: Dr Abigayle Ng (RSI) & Dr Jeffrey Lee (RSI)

Title: Bioengineering – Rapid diagnosis of Glucose-6-phosphate dehydrogenase deficiency using portable NMR

Synopsis: Glucose-6-phosphate dehydrogenase (G6PD) is a ubiquitous enzyme that plays a central role in the support of cellular redox processes. G6PD deficiency (G6PDD) is a very common X-linked recessive genetic disorder affecting approximately 400 million people worldwide. It results in an impaired ability of red blood cells (RBCs) to deal with oxidative stress, which often leads to their lysis (haemolysis) after exposure to certain foods, infectious microorganisms, or medications. In Singapore, every new-born child is screened for G6PDD. However the methods used are usually antiquated, with poor sensitivity and an inability to measure the extent of the mutant phenotype in heterozygous females. Although heterozygous individuals may remain asymptomatic despite expressing lower levels of the enzyme, they are still at high risk for acute haemolytic attacks. The laboratory has been developing a novel portable Nuclear Magnetic Resonance (NMR) device to rapidly and reliably detect G6PDD from human blood samples. The NMR method in development measures the Fe2+: Fe3+ ratio in red blood cells (RBCs) as an indicator of the G6PD levels. Since RBCs from G6PDD patients are less capable of dealing with oxidative stress, most of the iron will thus be in the higher 3+ oxidation state. The aim of this project is to optimise the application of the miniaturized NMR device to rapidly detect oxidative stress in the RBCs, and hence aid in the diagnosis of G6PDD. Students would be expected to focus on developing a simple microfluidic chip to be used together with the NMR system. We will expose students to using their physical and engineering knowledge in designing a microfluidic chip and validate with computational works.

Research work will be done at SMART-BioSyM laboratory located in the NUS campus. No work on blood or human tissues is involved.

Principal Investigator: Dr. Peng Weng Kun (SMART-BioSyM), Dr. Bruce Malcolm Russell (NUS), Dr. Lee Zhiying (RSI)
