研究方向:

Yan is a statistician and applied statistician with PhD in statistical epidemiology, MSc in health data science and BSc degree in mathematics. Yan is also an experienced statistical programmer as he has worked in a data management company and has conducted extensive statistical analysis in his MSc and PhD project for 6 years. He has expertise using electronic health records (EHR) to conduct epidemiological studies. He is also experienced in conducting statistical analysis and fulfilling the Food and Drug Administration (FDA) requirements for clinical trials of new medicines as he conducted multiple projects in the analyses of trial data. His current research area focuses on assessing the generalisability of risk prediction models (including traditional risk prediction model and machine-learning (AI) models) using EHRs from UK databases.

课题组招生说明:

Yan is recruiting master students who are interested in applied statistics, statistical programming, statistical epidemiology, health data science, clinical risk prediction model and machine learning.

Introduction of the master program with Dr. Yan Li

Within the master program hosted by Mathematic academy of Xiamen University, the master student is expected to pass all the required master courses and successfully defend their master dissertation to be award the master-degree. To do so, the master students are expected to take the mandatory master courses while working on their master project which is designed and guided by their supervisor. The master project is normally a real-life scientific research project with amount of public interests while the supervisor is the expert in such domain.

Working with Dr. Yan Li in the master program, you will be directed to either antibiotic over-prescribing program or Clinical risk prediction model program (i.e., your master project would be derived from one of the programs). Antibiotic over-prescribing is a global concern as it increases antimicrobial resistance (i.e., the more antibiotics you use, the less effective these antibiotics would be). Statistical models and machine learning models are used to study prescription behavior to help reduce the number of antibiotics being prescribed. Clinical risk prediction models are mathematical/statistical/machine learning models being used in clinical settings to help clinicians and patients in clinical decision making. For example, Clinical risk prediction model such as QRISK3 was developed to help prevent cardiovascular disease (CVD), which is the leading cause of death around the world for decades. Further improving generalisability and clinical utility of these models is of interest in the current research area.

Yan is also open to self-proposed research project if the student has a strong feeling or interests to do so.

Visions and Expectations

Yan's lab is research focused. This means master students like you should have some level of general interests in science and research, and you will be trained on research skills and being participated in real-world research project since day 1. The lab is built on global standard which suggests you will be training on writing essays and presenting in English. Despite of research skills, the lab offers opportunity to develop other skills such as general working skills and programming skills that will be useful in your career. The student is expected to work on his/her master project while not taking classes. The group meeting will be held weekly to discuss progress and results.

It is advised to take Yan's class to know him if you are undergraduate students in XMU or have a casual chat with him before applying.
