Title: Digital Pathology for Non-Alcoholic Fatty Liver Disease Diagnosis
Abstract: AI in medicine has become a popular and important interdisciplinary research area. Around 30% of adults worldwide are suffering different degrees of liver diseases, e.g. fatty liver and hepatitis which may further progress to liver cancer. Liver cancer is also the leading cause of cancer death in the world and the second most common cause of cancer death in the Asia-Pacific region. In this talk, I will share my research work on liver biopsy image analysis for non-alcoholic fatty liver disease. Specifically, I would like to share two recent research works for determining fibrosis staging and non-alcoholic fatty liver disease activity score from liver biopsy images.

Title: Image-based Primary Open-angle Glaucoma Diagnosis and Model Fairness
Abstract: Primary open-angle glaucoma (POAG) is one of the leading causes of blindness globally and in the US, potentially affecting an estimated 111.8 million people by 2040. Among these patients, 5.3 million may be bilaterally blind. POAG remains asymptomatic until it reaches an advanced stage, leading to visual field loss. However, early diagnosis and treatment can avoid most blindness caused by POAG. Therefore, accurately identifying individuals with glaucoma is critical to clinical decision-making. In recent years, developments in artificial intelligence have offered the potential for automatic POAG diagnosis and prognosis using fundus photographs. In this talk, I will review our research on image-based POAG diagnosis. I will also discuss how we are working to ensure model fairness across protected groups in deep learning models. Our proposed approach aims to alleviate concerns about the fairness and reliability of image-based computer-aided diagnosis.

Title: Transcriptomic, histopathological and radiological deep learning models for cancer subtype classification
Abstract: It is now clear that major human cancers are heterogeneous diseases, which hamper the selection of patients for optimized clinical management and treatment. To dissect the complex cancer heterogeneity, molecular subtyping has been widely adopted as an effective strategy in the last couple of decades. Despite the insights into cancer biology, the conventional cancer subtyping studies were mostly based on conventional machine learning methods applied to transcriptomics data, which lack cross-platform robustness and are not suitable for clinical translation. In this talk, I will first introduce a deep learning framework based on transcriptomic profiles, which is platform independent, robust to missing data, and can be used for single sample prediction. To facilitate clinical implementation, I will next introduce our recent works on deep learning models for cancer subtyping based on histopathological images and radiological scans. These medical imaging data is widely available in the clinic, hence more suitable for the translation of cancer subtyping into real clinical practice to advance precision oncology.

Title: Application of data science technologies in the precision medicine of brain cancer
Abstract: Recent advancements in next-generation sequencing and data science are revolutionizing various areas of life science and medicine. I am dedicated to discovering and investigating genomic alterations that impact complex human diseases and relevant biological models by developing and applying computational methods based on statistics and machine learning, in order to bridge the gaps between data, bench, and bedside. While large-scale genome sequencing projects have uncovered the mutational landscapes of several cancers, how cancer cells evolve with and without therapy remains unclear. My lab aims to address long-standing questions regarding how cancer cells respond to therapy and how the founding somatic alterations drive cancer evolution trajectories. In this talk, I will present the latest research from my laboratory on cancer evolution and precision medicine in the study of brain tumors.

Title: A Generalized Label-efficient Framework for Medical Image Segmentation and a new Benchmark for Colorectal Cancer Segmentation
Abstract: Medical image segmentation plays a crucial role in clinical settings, augmenting the accuracy of diagnosis, treatment planning, and disease surveillance. Here we present a generalized weakly supervised framework for medical image segmentation, termed WeakMed, to alleviate the reliance on costly annotations while being tractable to various scenarios. Specifically, the proposed WeakMed method creatively utilizes the mask-to-box transformation to overcome rectangular shape biases inherent in bounding box labels by leveraging economical bounding box annotations, thus largely streamlining the annotation of medical data. Besides, WeakMed is a versatile model, enabling adaptation to a variety of segmentation tasks and bringing no computation costs to model inference. Through rigorous evaluation across 9 segmentation tasks, 10 diverse medical datasets, and 6 distinct imaging modalities, WeakMed demonstrates superior accuracy and robustness when compared to its fully/weakly supervised counterparts. By alleviating the data annotation burden associated with a broad spectrum of segmentation tasks, WeakMed has the potential to advance diagnostic accuracy and facilitate the development of personalized treatment strategies. Besides, we collected and annotated the first benchmark dataset that covers diverse ERUS scenarios, i.e. colorectal cancer segmentation, detection, and infiltration depth staging. Our ERUS-10K dataset comprises 77 videos and 10,000 high-resolution annotated frames.
