How do social positions, institutions, and unequal resources shape the choices people can make and the outcomes they encounter?
Medical sociology · Social inequity · Malaysia
Making social research actionable.
I’m Chee-Yeong YAP, a sociologist working primarily in medical sociology and more broadly on social inequity. I study how social structures produce unequal outcomes—and where rigorous evidence can identify credible points for change.
Current emphases
Qualitative inquiry as my primary stance, strengthened by quantitative analysis and mixed-method integration.
To connect lived experience and statistical pattern with questions of access, responsiveness, and social equity.
Academic journey
From systems that could be calculated to lives that had to be understood.
EngineeringWork & societyHealth inequity
My academic journey began in engineering, where I learned to value precision, structure, and evidence. Yet the questions that stayed with me were not only technical: why do people living within the same society encounter such different possibilities, and why does suffering persist even when institutions are designed to help? Equations could describe a system, but they could not fully explain how that system was lived. Sociology gave me a language for those questions—and a way to study something that did not stay still.
During my master’s research, I examined industrialisation and work values in Malaysia. The project taught me the full craft of research: turning an intuition into a defensible question, building a study, analysing evidence, and carrying an argument into publication. It also exposed a limit. Mapping differences was valuable, but description alone could not show how those differences were produced or where change might begin.
That concern became urgent during my doctorate, when I studied the diagnostic pathways of people with nasopharyngeal carcinoma. Here, inequality had consequences measured in missed symptoms, costly travel, time away from work, delayed escalation, and heavier treatment. Drawing on intersectionality, critical realism, and patients’ accounts, I began tracing how culture, material conditions, social position, and institutional practice become consequential together. This work led to the Intersectional Categorical Influences Framework: an attempt to organise complexity without flattening it, and to move from identifying inequity toward locating credible points for action.
Qualitative inquiry remains my primary methodological stance, but engineering never entirely left my way of thinking. Quantitative and mixed-method research allow me to examine patterns, relationships, latent structures, and variation across groups; qualitative research helps explain how those patterns are produced and lived. Across health, work, and wider social inequity, the commitment is the same: research should be rigorous enough to withstand scrutiny, sensitive enough to recognise the people behind the evidence, and useful enough to clarify where change can begin.
Research proposition
Every encounter with a system begins in a life already shaped by society.
That life includes work, family, distance, cultural meaning, institutional trust, and the uneven capacity to act.
01 / Research
Four connected lines of inquiry.
Each begins with lived experience and asks how wider arrangements become consequential in everyday health and social life.
01 · Cancer pathways
Routes to diagnosis
Patient experience and the intersecting cultural, material, and institutional conditions shaping nasopharyngeal carcinoma diagnostic pathways in Malaysia.

From description to action
The Intersectional Categorical Influences Framework connects meaning, material conditions, institutions, consequences, and possible leverage points.
