RESEARCH

 

Effects of Climate Change

How do organisms deal with the rapid change in the environment?  What is the effect of climate change on marine organisms? 

How do organisms already live in e.g. acidic environments?

Transgenerational & Parental Effects

Organisms react to their environment. Do they then pass on what they have learned to the next generation? If so, how?

We want to understand the mechanisms of parental effects and if they can help adaptation to future climate change conditions.

Behaviour & the Brain

Behaviour is often altered with a change in the surrounding environment. We want to understand how the environment can influence behaviour and how neuro-molecular states in the brain can drive this behavioural change.

Population Connectivity & Ecological Genomics 

How populations are connected or isolated is important in terms of local adaptation as well as population resilience. We study how recruitment of larvae to marine populations allows for population connectivity and investigate how isolated populations survive.

Ph.D STUDENTS

Sneha Suresh

Sneha is originally from India and received her Bachelor’s degree in biotechnology from Ramaiah Institute of Technology in 2017 and a Master’s in Biology from the University of Massachusetts Lowell, USA, in 2019. Her Master’s thesis was focused on investigating the effects of copper toxicity on alternative splicing in Daphnia. Sneha is fascinated by how organisms regulate their genome to deal with changes in the environment.

As part of her Ph.D. thesis, she is investigating the gene expression responses in the spiny damselfish to conditions of ocean acidification. Her aim is to understand the influence of parental exposure on the offsprings’ response to pH change. While changes in ocean chemistry can have short-term negative effects on fishes and other marine organisms, they have the potential to acclimate to the acidic environments across generations. Intergenerational acclimation could, therefore, have long-lasting effects on future generations enabling them to adjust to more acidic environments. During her Ph.D. Sneha hopes to better understand the transcriptomic and epigenetic basis of intergenerational acclimation. She mainly relies on bioinformatics tools and approaches in her research to analyze and interpret an organism’s response to environmental change at the molecular level.

While not in the lab she enjoys hiking, reading mystery/ adventure fiction, scuba-diving and playing the violin.

 

Jade Sourisse

is from France, she studied at Lille University where she received her Bachelor's in Life Sciences in 2017 and she graduated from Sorbonne University in Paris with a Master's degree in Biodiversity and Conservation of Marine Ecosystems. For her Master's thesis, she studied the impact of habitat quality on gut microbiome communities in the foureye butterflyfish Chaetodon capistratus. 
Jade is interested in using the power of molecular studies to investigate the effect of climate change and human activities on marine organisms and ecosystems. 
For her PhD thesis, Jade will focus on the effects of ocean acidification on the behaviour and related learning abilities and gene expression of the California sea hare (Aplysia californica). Unlike other marine species like fishes, the nervous system of Aplysia californica is well-mapped and neurons involved in specific behaviour have been identified. 
Jade's aim is to describe how is the sea hare's behaviour impaired and to observe whether gene expression in the involved components of the nervous system changes under near-future CO2 conditions.

Kang's Google Scholar

Dr. Kang Jingliang

is from China. He obtained his Bachelor’s degree in Aquaculture from Southwest University in 2013 and received his Ph.D in Aquatic Biology from the Chinese Academy of Sciences in 2018. He joined our team as a postdoc in August 2019. During his Ph. D, he focused on the high-altitude adaptation analysis of Creteuchiloglanis macropterus by population genetics (RAD-seq) and RNA-seq, which is a glyptosternoid fish that inhabits in Yunnan Province and Tibet, China. Kang is interested in investigating the molecular responses of fishes to specific environments through genome scanning.

Currently, he is investigating the molecular response of coral reef fishes to living in natural CO2 seeps (lower pH) by comparing the differences in brain gene expression in fish from a CO2 seep to nearby control reefs. He aims to detect the putative genes that are related to control of the cellular responses to elevated CO2 and to provide the common but also variable molecular mechanisms among species in coping with elevated CO2.

In his free time, Kang plays basketball, swims and likes watching sports.

Sandra Ramirez

is originally from Cali, Colombia. She studied in Universidad del Valle, where she obtained her degree in Biology with an emphasis on Marine studies in 2016. Her thesis was on the population genetics and connectivity of a damselfish (Stegastes flavilatus) among marine protected areas in the Colombian Pacific. After that, Sandra participated in a variety of studies involving fish ecology and coral plasticity in her coral reef research group and lead projects about local ecosystem conservation in Cali to finally join the Schunter lab in April 2019.

Currently, Sandra’s research involves the study of the molecular mechanisms of the cleaning behaviour of the coral reef fish Labroides dimidiatus. She is interested in identifying the molecular pathways that may be associated with the interactions of cleaner fish and its potential clients, and how different environmental conditions associated with ocean acidification may affect them as well. In addition, Sandra is interested in analyzing potential evolutionary adaptations that these organisms may have when exposed to different environmental conditions.

Even though Sandra loves diving and exploring the sea, she also loves to go into the jungle and observe terrestrial animals such as birds, frogs, and mammals. She loves to go into fieldwork but enjoys working in the lab as well. She is also a fan of salsa music, movies, and travel!

 

Arthur Chung

is from Hong Kong and received his Bachelor’s degree in Ecology & Biodiversity from the University of Hong Kong (HKU) in 2017. As a research assistant after his studies, he worked on applying population genomic data into marine restoration of local gorgonians. Such experience had made him recognise his passion in pursuing marine conversation by utilising the power of molecular tools and techniques.

As part of his MPhil thesis, he is investigating the ecological impacts brought from the mercy release of hybrid grouper (Epinephelus fuscoguttatus x E. lanceolatus) into the wild by performing gut content analysis with metabarcoding. The hybrid grouper is carnivorous and released into the wild in large quantities, yet there is a complete lack of information on the ecology of the wild populations.

His ultimate goal is to utilize genomic data to understand the speciation processes within the genus Epinephelus and reveal if any hybridization events occurred in the past that are contributing to species diversification.
