Postdoctoral Fellows


Dr. Ng Kwun Kei (Eric)

As a Post-doc, I am responsible for incorporating EEG measures and fMRI data obtained in concurrent EEG-fMRI recordings. Currently I am involved in the investigation of the developmental changes in functional connectivity.

My education has been in cognitive psychology. I obtained my doctoral degree in NUS. In my PhD thesis, I used EEG and ERP to study how human estimates time. Time perception is pertinent to human cognition and is impaired in many neurological disorders; it is a research topic that I am interested in pursuing further.


Dr. Liu Siwei (Cisy)

As a research fellow in Dr. Zhou's lab, I'm responsible for designing psychological experiments, performing neuroimaging research using EEG and fMRI, and developing new data analysis methods. Currently I am involved in studies on dementia and aging.

I have been primarily interested in the neural basis of cognition, memory, and emotion in humans, and have explored these topics using EEG and fMRI. I did my PhD at NUS. For my doctoral thesis, I studied the event-related potentials visual P1 and the N170, to investigate the cross-modality effects of conceptual categorization on visual object processing.

Dr. Juan Wang

As a research fellow, I am responsible for developing analysis methods for EEG-fMRI recordings and exploring the dynamic characteristics of brain connectivity measured with fMRI.

I received my PhD degree in Control Science and Engineering from Yanshan University, China, in 2015. My PhD research work focused on EEG data analysis. Spectrum power, linear correlation and cross-frequency coupling have been used to analyze neural oscillations of brain activities. Some pathophysiological characters of chronic pain and interaction of bottom-up and top-down processes in speech perception of children have been revealed.

Dr. Xing Qian

As a research fellow, I am responsible for performing researches on functional connectivity using fMRI. Currently I am involved in the ADHD project.

I received my doctoral degree in Tsinghua University (China) in 2016. In my PhD thesis, I focused on the deep brain stimulation (DBS) related local field potential (LFP) recording from the Parkinson’s disease patients. I developed and implemented the long-term LFP recording on the platform of DBS, and conducted the clinical trials for the study on the relationship between the DBS parameters and the pathophysiological oscillations of the PD patients.

Dr. Liwen Zhang

I am a research fellow in Dr. Zhou's lab, working on projects related to dementia. The research questions driving me are: what are the brain mechanisms underlying disturbances in people with dementia, and what contributes to the transition from non-dementia to dementia?

I obtained my PhD in neuroscience from the University of Groningen (the Netherlands). During my PhD, I studied the neural correlates of emotion regulation and self-reflection in mood disorders and schizophrenia, using fMRI.



Affiliated Research/Clinical Fellows


Dr. Chenhao Wang

As a PhD student, I am interested in the study of longitudinal brain changes using multimodal neuro-imaging techniques. Currently, I am also helping in projects of developing imaging biomarkers to diagnose psychiatric conditions.

I graduated with B. Chem Eng from NUS. Neuroscience is one of the fastest growing area in medicine and there are still lot of questions to be answered. I am very excited about coming research opportunities in our lab.


Dr. Jia Hou Poh

I am currently involved in a project studying functional connectivity underlying individual differences in visuospatial and emotional processing.

The study of cognitive faculties has always been an area that greatly fascinates me. Through the studying of neurological networks, I hope to gain a better insight of human cognitive capacities. My main area of interest revolves around the study of memory and unconscious processing.

Outside of the lab, I enjoy strumming mindlessly on my ukulele while sipping a nicely brewed cup of tea.

Dr. New Fei Ho

I am a visiting fellow and collaborate with Helen Zhou's lab on various projects, including morphometry and connectivity analyses on subjects with schizophrenia, bipolar disorder, and ADHD.

I obtained my Ph.D. in Pharmacology from the National University of Singapore and did my postdoctoral training under the Psychiatric Neuroimaging and Schizophrenia Clinical and Research Programs, Massachusetts General Hospital; Harvard Medical School.
