About Us

We are a multidisciplinary research team at Chulalongkorn University, Bangkok, Thailand. Our lab locates in Chula Neuroscience Center, King Chulalongkorn Memorial Hospital. We focuses on foundational rules and computational principles that govern human cognition using psychological experiments, computational modelings and various neuroimaging techniques such as EEG, fMRI, fNIRs and brain stimulations. We hope that deeper understandings of how the human mind works will help us shed light on underlying mechanisms of various neurocognitive disorders.

In the lab

    We expect our lab members to gain useful research experience AND live a happy and fulfilling lab life. As much as we want the research to be done (for the sake of the science community and our curiosity!), we want to create a positive, constructive and relaxing work environment. We encourage everyone to express their thoughts and ideas. We also want to see people in the lab working as a team to initiate, plan, organize and run projects on their own but get helps and supports whenever needed.

    We have regular lab activities and expect regular lab members to join and participate in academic and not-so-academic activities (which are a LOT more :D) when possible.

Opportunity

We are actively looking for graduate students. Nonetheless, anyone who loves or has some backgrounds in either neuroscience, psychology, medicine, data science, programming, machine learning, statistics, linguistics are welcome. If you are interested in joining our team, email us!

        • (good to know) Classical experimental paradigms e.g. Posner cueing paradigm, N-back task, Go-No-Go, Egly-driver paradigm, Visual Search, Multiple object tracking, Pair-association paradigm, delayed recall, Semantic priming, Anne and Sally task, Prisoner dilemma, Trolley problem etc.

        Our lab members use various programming languages; Python Matlab R Javascript HTML CSS C#. Python and R are used most for data analysis and are recommended for those who have no prior background on programming. HTML, CSS and Javascript C# are, sometimes, needed in the development of custom neuro-psychological tasks. For better research experience, we recommend knowing at least one of Matlab, Python and R language to the level of the following tasks:

        • (wow, really?) Knowledge about Machine Learning and Deep Learning

    Our lab cares about cultivating young minds as much as doing science. Thus, we want to make sure that our lab members are gaining enough valuable experience and living in a nourishing environment. Here are some basic agreements that we really value.

    • We will have regular friendly lab meetings every 1 - 2 weeks. The aims are to share new ideas, research findings, research progressions, any cool or wacky brain stuff really. We expect our members to attend, share ideas, thoughts, and give constructive comments.

    • We are learning new things every day. Learning how to work and solve problems both independently and as a group or “learning how to learn (together!)” is actually very important. Please mentally prepare to learn and work as a group. Most projects here need team efforts.

    • As much as we want everyone to accomplish what they want, we totally understand that sometimes unexpected circumstances might occur. Please do not get discouraged and please let us know (We also understand that not everyone is comfortable in doing so. In case that we lose contact with you for more than 4 weeks, please do understand that we would assume that you might be in that situation)

    • We do not particularly care about your work time and place as long as you can manage to meet your timeline. However, we believe that being together in the same place is essential in building relationships and learning from each other (Shhhh! And don’t tell anyone that we also have a lot of sweet and yummy dishes in the lab). In case you have difficulty organizing your time, we also would be happy to help!

    • Sometimes we have fun with the project and we would like to talk about it all day. That’s cool as long as it’s completely spontaneous. We care a lot about work-life balance and don’t expect people to respond to emails or calls outside office hours.

    • We love hearing bold, fun, creative, new ideas from various perspectives. This is why our members came from many disciplines. It is also exactly why we cherish all kinds of diversities including but not limited to culture, ethnicity, race, gender, social status, educational background, health-related issues. Our lab expects everyone to be respectful and thoughtful.
