Structural Pharmacology of Nav and Cav channels

Voltage-gated sodium (Nav) and calcium (Cav) channels are responsible for the initiation of electrical signaling. Being associated with a variety of disorders, Nav and Cav channels are targeted by multiple pharmaceutical drugs and natural toxins. Taking advantage of the resolution revolution of single particle cryo-EM, we have determined the structures of different Nav and Cav subtypes from human and other eukaryotes. These structures, alone or in complex with distinct auxiliary subunits, toxins, and drugs, not only afford unprecedented insights into the working and disease mechanism of these channels, but also reveal novel pharmacological sites. In light of these structural advances, we proposed a structure-based nomenclature for ligand binding sites on Nav and Cav channels, which may facilitate rational drug design and optimization.

She joined School of Medicine, Tsinghua University as a professor in 2007. Ten years later, in 2017, she was recruited back by Princeton University and became the inaugural Shirley M. Tilghman Professor of Molecular Biology. In 2022, Yan Nieng served as the Founding President of Shenzhen Medical Academy of Research & Translation (SMART). In 2023, she served as the Director of Shenzhen Bay Laboratory (SZBL). Dr. Yan’s primary research interest has been in the structural and mechanistic investigation of membrane transport proteins that are of tremendous physiological, pathophysiological, and pharmaceutical significance. She reported the first structures of the human glucose transporters GLUT1 and GLUG3, the eukaryotic voltage-gated sodium and calcium channels, and a number of proteins involved in sterol metabolism. Her present research program focuses on structure-guided mechanistic understanding and drug discovery for pain relief. Her achievements have won her numerous accolades.


Challenges and Opportunities of Interpretable AI

Wenjun (Kevin) Zeng, Ph.D.

Chair Professor, Eastern Institute of Technology, Ningbo, China

Artificial Intelligence (AI) has experienced tremendous growth and brought waves of excitement in the past decade, thanks to the advancement of deep learning technologies and more recently large generative AI models such as ChatGPT/Sora. However, the “black-box” nature of current AI technologies poses significant challenges on the trustworthiness of AI Models, which potentially will impede the adoption of AI, especially for mission critical applications, and be a road blocker for achieving Artificial General Intelligence. In this talk, we first present the concept of interpretable AI and highlight its importance as well as challenges. We then discuss the opportunities to address this issue, highlighting the concept and approaches of disentangled representation learning, and the interpretable and controllable process of AI content generation. We will also discuss some future trends.

Wenjun (Kevin) Zeng has been a Chair Professor and Vice President for Research of the Eastern Institute of Technology (EIT), Ningbo, China since Oct. 2021. He is also the founding Executive President of the Ningbo Institute of Digital Twin (IDT). Prior to that, he was a Sr. Principal Research Manager and a member of the Senior Leadership Team at Microsoft Research Asia where he was leading the video analytics research powering the Microsoft Cognitive Services, Azure Media Analytics Services, Microsoft Office, Dynamics, and Windows Machine Learning. He was a professor with the Computer Science Dept. of Univ. of Missouri from 2003 to 2016. Prior to that, he worked for PacketVideo Corp, San Diego, CA, Sharp Labs of America, Camas, WA, Bell Labs, Murray Hill, NJ, and Panasonic Technology, Princeton, NJ. He has contributed significantly to the development of international standards (ISO MPEG, JPEG2000, and Open Mobile Alliance). He received his B.E., M.S., and Ph.D. degrees from Tsinghua Univ., the Univ. of Notre Dame, and Princeton Univ., respectively. He is on the Editorial Board of International Journal of Computer Vision, and was an Associate Editor-in-Chief, Associate Editor, or Steering Committee Member for a number of IEEE journals. He has served as the General Chair or TPC Chair for several IEEE flagship conferences (e.g., ICME’2018, ICIP’2017). He is a Fellow of the IEEE and a Fellow of Canadian Academy of Engineering.


Build an end-to-end scalable data science ecosystem by integrating statistics, ML, and Domain Science

The data science ecosystem encompasses data fairness, statistical, ML methods and tools, interpretable data analysis, and trustworthy decision-making. Rapid advancements in ML have revolutionized data utilization and enabled machines to learn from data more effectively. Statistics, as the science of learning from data while accounting for uncertainty, plays a pivotal role in addressing complex real-world problems and facilitating trustworthy decision-making. In this talk, I will discuss the challenges and opportunities involved in building an end-to-end scalable data science ecosystem that integrates statistics, ML, and domain science. I will illustrate key points using the analysis of whole genome sequencing data and electronic health records. This talk aims to ignite proactive and thought-provoking discussions, foster collaboration, and cultivate open-minded approaches to advance scientific discovery.

Addressing Climate Change: Negative Emission based on AI-Driven Evolution of Advanced Materials

Chair Professor and Dean, School of Interdisciplinary Studies

Lingnan University

To address the global challenge of climate change and sustainability, revolutionary solutions are needed to develop highly efficient pathway for mitigating carbon dioxide and greenhouse gas emissions. The “Holy Grail” is engineered removal of CO2 directly from the atmosphere, known as negative emission. Conventional carbon capture method developed for power and chemical plants does not work well for air capture, due to the very different CO2 concentration in flue gas and air. We present a disruptive approach of DAC (direct air capture of CO2), which is enabled by unconventional reverse chemical reaction driven by water quantities in nanopores. The humidity-swing system absorbs CO2 from the air when the surrounding is dry, whereas releases CO2 when wet. AI-driven material and system design is employed to significantly promote DAC capacity and efficiency, leading to perhaps the world’s cheapest solution of negative emission. The carbon loop is further closed by distributed and need-based capture of CO2 and various pathways of CO2 conversion, forming the technological roadmap of distributed carbon capture, utilization, and sequestration (distributed CCUS). The future prospects of engineering the carbon loop and grand cycles of sustainability are also discussed.
