Professor Douglas H. Kelley, University of Rochester

Title: Microscale flows removing waste from the brain: Drivers, characteristics, and mysteries

Abstract:The human brain accounts for just 2% of the body's mass but metabolizes 25% of its calories, producing significant metabolic waste. However, waste buildup links to neurodegenerative diseases like Alzheimer's and Parkinson's. The brain is thought to remove waste via the recently-identified glymphatic system, a combination of spaces and channels through which cerebrospinal fluid could flow to sweep away toxins like amyloid-beta. With an interdisciplinary group of neuroscientists and physical scientists, I study the fluid physics of the glymphatic system: Where does fluid flow, and how fast? What drives flow? What characteristics of the system enable essential functions? How can we improve waste removal? Can we use glymphatic flow to deliver drugs? The team combines physics tools like particle tracking and newly-invented front tracking with biological tools like two-photon imaging through cranial windows in order to address these questions with in vivo flow measurements. I will talk about recent results showing that glymphatic flow proceeds along vessels with near-optimal shapes, pulses with the heart, is driven by artery walls, can be manipulated by changing the wall motion, and is the dominant source of swelling soon after ischemic stroke. 

Bio: Douglas H. Kelley is an Associate Professor of Mechanical Engineering and earned a PhD in physics from the University of Maryland. He held postdoctoral appointments at Yale University (in mechanical engineering) and Massachusetts Institute of Technology (in materials science and engineering). Previously he earned an MS from Auburn University and a BS from Virginia Tech. Doug is a member of the American Physical Society, ASME, and AAAS. 


Professor Koji Takahashi, Kyushu University

Title: Gas molecules at solid-liquid interfaces

The physics of solid-liquid interface is very fascinating where many fundamental phenomena are left unsettled in a wide range of science and technology fields. The talk will provide new insight to the gas molecules just on the interface experimentally studied by using AFM and TEM. For example, generation and growth of interfacial nanobubbles are explained with the consideration of unique gas phases thinner than 5nm. Technical tips are also introduced for successful observation of water at the nanoscale.


Koji Takahashi received his Doctor of Engineering from the University of Tokyo, Japan in 1992. He is currently a Professor in Aeronautics and Astronautics at Kyushu University and WPI Professor at the International Institute for Carbon-Neutral Energy Research, Japan. His major interests are micro/nanoscale heat transfer and thermal property of nanomaterials. He has published more than 150 archival Journal articles and peer-reviewed conference papers and was awarded the Scientific Award of the Heat Transfer Society of Japan in 2008 and 2020, JSME Medal for Outstanding Paper in 2012, and Thermal Engineering Achievement Award of JSME in 2016.

Title: The Roles of Fluid Flow in Immune System Function


One of the life-sustaining roles for the lymphatic system is to gather information on infections so that the body’s immune system can develop appropriate defenses.  Fluid mechanics plays crucial roles at multiple scales in the collection of interstitial fluid and antigenic information into lymph nodes for further processing.  Lymph nodes are immune information collection and transfer junctions, where immune cells are housed in sufficient numbers and varieties to develop effective immune responses.  The type of information delivered to the lymph nodes includes free antigen, antigen presenting cells, cytokines and other immune cells/signals.  Once inside the node, the information must be relayed to the correct region, where carefully orchestrated processes in specific nodal compartments result in the production of antigen-reactive cells and/or antibodies.  These processes also rely on fluid flow and cytokine transport.  Adaptive immunity thus requires an exquisitely complex combination of active pumping, cell/antigen transport, and biological signaling between multiple cell types. 

Employing a combination of in vivo and excised vessel experiments, along with multiscale lumped parameter modeling, we have analyzed the effects of local pressure conditions and vasoactive substances on vessel pumping dynamics.  Pumping dynamics of afferent vessels, and therefore the delivery of immune information to lymph nodes, are strongly affected by variations in local pressure, including the external pressure and vasoactive effects of vaccinations.  We have also performed a series of microfluidic chamber experiments and computational simulations of flow patterns within lymph nodes.  Lymph flow helps to shape concentration gradients of chemokines that provide guiding cues for antigen presenting cells to interact with B and T cells.  A better understanding of these transport phenomena could lead to more relevant criteria for designing methods to modulate the immune system effectively for health benefit, including vaccines.


Prof. Moore received his Ph.D. from the Georgia Institute of Technology, followed by postdoctoral training at the Swiss Institute of Technology at Lausanne.  Prior to coming to Imperial College, he was the Carolyn S. and Tommie E. Lohman ’59 Professor of Biomedical Engineering at Texas A&M University. In January 2013, he joined Imperial College as the Bagrit and Royal Academy of Engineering Chair in Medical Device Design in the Department of Bioengineering.  Prof. Moore’s research interests include Cardiovascular Biomechanics, Stents, Implantable Devices, Atherosclerosis, and the Lymphatic System. His research focuses on the role of biomechanics in the formation and treatment of diseases such as atherosclerosis and cancer. His cardiovascular biomechanics work resulted in the development of two novel stent designs aimed at optimizing post-implant biomechanics for the prevention of restenosis, as well as new testing devices for implants that employ more physiologic mechanical forces. His research on lymphatic system biomechanics has provided unprecedented insight into the pumping characteristics of the system and the transport of nitric oxide, antigens, and chemokines in lymphatic tissues. He is currently developing two technologies for preventing and resolving secondary lymphedema, which typically forms subsequent to cancer surgery. Along with his funding from government, charity, and industry sources, Prof. Moore has received multiple patents for medical devices and testing equipment.  Prof. Moore has also co-founded three startup companies.  He is a Fellow of ASME, AIMBE and IMECHE.
