In this talk, I will present our approach to bridging these regimes by programming material architecture, connectivity, and active response across multiple scales.<br>\r\nI will first show how geometric and topological design can overcome the trade-off between shape morphing and stiffness. Scale-inspired layered structures combine complex deformation with controllable load-bearing capacity, while topologically interlocked fabrics use collective interactions and jamming to transition from conformable sheets to stiff structures. Active fibers and hierarchical tessellations further enable programmable three-dimensional morphing and customized human assistance. I will also introduce granular metamaterials with reconfigurable bonds that assemble, disassemble, and rearrange to achieve adaptive mechanical and robotic functions. Finally, I will discuss coaxial direct ink writing as a strategy for embedding conductive pathways, dielectric insulation, and actuation directly into three-dimensional structures. The resulting electrostatic fibers and lattices enable programmable clutches, shape morphing, artificial muscles, and swimming robots. Together, these studies establish a pathway from soft matter to strong, active, and adaptive robotic systems.<br>\r\n<br>\r\n<strong>Biography: </strong>Dr. Yifan Wang is an Associate Professor in the School of Mechanical and Aerospace Engineering at Nanyang Technological University, Singapore, where he leads the Robotic Materials Group.

I will describe viral technologies developed by my group that address each of these challenges. These include INTRSECT, a Boolean viral targeting strategy for cell-type- and circuit-specific access; VESPA, a novel split-AAV platform that enables efficient reassembly and expression of genetic payloads too large for a single AAV; and CRISPR/Cas9-based strategies for precise, cell-type- and circuit-specific gene knockdown. Together, these tools form an integrated viral toolkit for programmable access to and manipulation of neural circuits across multiple levels of biological complexity.<br>\r\n<br>\r\n<u><strong>Bio:</strong></u><br>\r\nDr. Lief Fenno is a physician-scientist at The University of Texas at Austin and Dell Medical School. His research integrates systems neuroscience, synthetic biology, and bioengineering to develop genetic, viral, and neuromodulation technologies for programmable control of neural circuits in vivo. His laboratory develops molecular and viral platforms for selectively accessing and manipulating defined neural populations, alongside approaches for neural stimulation and emerging therapeutic applications. His work spans fundamental circuit neuroscience, neurotechnology, and the translation of biological tools to treatment of brain disorders.

This model has a natural scaling limit that reconciles a number of salient empirical properties: persistent signed order flow, rough trading volume and volatility, and power-law market impact. In our framework, all these quantities are pinned down by a single statistic H, which measures the persistence of the core flow. Specifically, the signed flow converges to the sum of a fractional process with Hurst index H and a martingale, while the limiting traded volume is a rough process with Hurst index H - 1/2. No-arbitrage constraints imply that volatility is rough, with Hurst parameter 2H - 3/2, and that the price impact of trades follows a power law with exponent 2 - 2H. The analysis of signed order flow data yields an estimate H around 3/4. This is not only consistent with the square-root law of market impact, but also turns out to match estimates for the roughness of traded volumes and volatilities remarkably well.<br>\r\n<br>\r\nJoint work with Youssef Ouazzani Chahdi, Mathieu Rosenbaum and Gregoire Szymanski.<br>\r\n </p>", "image_description": "", "creation_date": "2026-08-31T15:23:49", "last_modification_date": "2026-11-02T16:10:58", "link_label": "", "link_url": "", "canceled": "False", "cancel_reason": "", "place_and_room": "UNIL, Extranef, room 126", "url_place_and_room": "", "url_online_room": "https://papers.ssrn.com/sol3/papers.cfm?abstract_id=6155066", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "<a href=\"https://www.ma.imperial.ac.uk/~jmuhleka/www.ma.imperial.ac.uk/~jmuhleka/\">Johannes Muhle-Karbe - Imperial College London</a>", "organizer": "", "contact": "[email protected]", "is_internal": "False", "theme": "", "vulgarization": { "id": 2, "fr_label": "Public averti", "en_label": "Informed public" }, "registration": { "id": 2, "fr_label": "Sur invitation", "en_label": "Invitation required" }, "keywords": "", "file": null, "icalendar_url": "https://memento.epfl.ch/event/export/121641/", "category": { "id": 1, "code": "CONF", "fr_label": "Conférences - Séminaires", "en_label": "Conferences - Seminars", "activated": true }, "academic_calendar_category": null, "domains": [], "mementos": [ "https://memento.epfl.ch/api/v1/mementos/3/?format=api", "https://memento.epfl.ch/api/v1/mementos/39/?format=api", "https://memento.epfl.ch/api/v1/mementos/105/?format=api", "https://memento.epfl.ch/api/v1/mementos/116/?format=api" ] }, { "id": 72481, "title": "Brown Bag Seminar in Finance", "slug": "brown-bag-seminar-in-finance-10", "event_url": "https://memento.epfl.ch/event/brown-bag-seminar-in-finance-10", "visual_url": "https://memento.epfl.ch/image/33726/200x112.jpg", "visual_large_url": "https://memento.epfl.ch/image/33726/720x405.jpg", "visual_maxsize_url": "https://memento.epfl.ch/image/33726/max-size.jpg", "lang": "en", "start_date": "2026-12-14", "end_date": "2026-12-14", "start_time": "12:15:00", "end_time": "13:15:00", "description": "", "image_description": "", "creation_date": "2026-08-31T15:36:49", "last_modification_date": "2026-09-10T16:51:49", "link_label": "", "link_url": "", "canceled": "False", "cancel_reason": "", "place_and_room": "UNIL, Extranef, room 126", "url_place_and_room": "", "url_online_room": "", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "Florian Perusset - PhD, SFI@EPFL", "organizer": "", "contact": "[email protected]", "is_internal": "False", "theme": "", "vulgarization": { "id": 2, "fr_label": "Public averti", "en_label": "Informed public" }, "registration": { "id": 2, "fr_label": "Sur invitation", "en_label": "Invitation required" }, "keywords": "", "file": null, "icalendar_url": "https://memento.epfl.ch/event/export/121642/", "category": { "id": 1, "code": "CONF", "fr_label": "Conférences - Séminaires", "en_label": "Conferences - Seminars", "activated": true }, "academic_calendar_category": null, "domains": [], "mementos": [ "https://memento.epfl.ch/api/v1/mementos/3/?format=api", "https://memento.epfl.ch/api/v1/mementos/116/?format=api", "https://memento.epfl.ch/api/v1/mementos/39/?format=api", "https://memento.epfl.ch/api/v1/mementos/105/?format=api" ] }, { "id": 72648, "title": "Sustainable Labs: Get Involved", "slug": "sustainable-labs-get-involved-2", "event_url": "https://memento.epfl.ch/event/sustainable-labs-get-involved-2", "visual_url": "https://memento.epfl.ch/image/33911/200x112.jpg", "visual_large_url": "https://memento.epfl.ch/image/33911/720x405.jpg", "visual_maxsize_url": "https://memento.epfl.ch/image/33911/max-size.jpg", "lang": "en", "start_date": "2026-10-08", "end_date": "2026-12-17", "start_time": "12:15:00", "end_time": "13:00:00", "description": "<br>\r\nThe <strong>EPFL Sustainable Labs team</strong> is pleased to welcome you to its recurring <strong>\"Sustainable Labs: Get Involved\"</strong> sessions. Held every week, alternating between <strong>Tuesdays and Thursdays</strong>, these sessions provide an opportunity for laboratories, platforms, centers, and units to receive guidance and support on implementing more sustainable laboratory practices.<br>\r\n<br>\r\nThe <strong>Sustainable Labs initiative</strong> is part of EPFL's <em>Climate & Sustainability Strategy 2030</em>, which aims to reduce greenhouse gas emissions by an average of <strong>40% compared to 2006/2019 levels</strong> and achieve <strong>climate neutrality by 2040</strong>.<br>\r\n<br>\r\n→<a href=\"https://www.epfl.ch/about/sustainability/sustainability/green-labs_draft_ag/\"> </a><strong><a href=\"https://www.epfl.ch/about/sustainability/sustainability/green-labs_draft_ag/\">Learn more about the EPFL Sustainable Labs initiative</a>.</strong><br>\r\n<br>\r\nResearch activities are a key lever for achieving these ambitious goals. However, while cutting-edge research drives innovation, it also carries a significant environmental footprint. Laboratories consume large amounts of energy, generate substantial quantities of plastic, chemical, and biological waste, and contribute considerably to greenhouse gas emissions. At EPFL, we are committed to understanding and reducing this impact. Through the development and deployment of the <strong>EPFL CO₂ Calculator</strong>, we help researchers measure, understand, and improve the environmental performance of their activities.<br>\r\n<br>\r\nFrom <strong>October 8 to December 17, 2026</strong>, the <strong>Sustainable Labs: Get Involved</strong> sessions will focus on training and supporting users in the use of the <strong>EPFL CO₂ Calculator</strong>. This tool enables laboratories, platforms, centers, and central units to estimate their carbon footprint, identify major emission hotspots, and support informed decision-making to reduce their environmental impact through targeted actions.<br>\r\n<br>\r\nHere are the planned sessions : \r\n<ul>\r\n\t<li>Thursday October 8th 12:15-13:00 (online) </li>\r\n\t<li>Tuesday October 13th 12:15-13:00 (MA A0 364)</li>\r\n\t<li>Thursday October 22th 12:15-13:00 (online) </li>\r\n\t<li>Tuesday October 27th 12:15-13:00 (MA A0 364)</li>\r\n\t<li>Thursday November 5th 12:15-13:00(online) </li>\r\n\t<li>Tuesday November 10th 12:15-13:00 (MA A0 364)</li>\r\n\t<li>Thursday November 19th 12:15-13:00 (online) </li>\r\n\t<li>Tuesday November 24th 12:15-13:00 (MA A0 364)</li>\r\n\t<li>Thursday December 3rd 12:15-13:00 (online) </li>\r\n\t<li>Tuesday December 8th 12:15-13:00 (MA A0 364)</li>\r\n\t<li>Thursday December 17th 12:15-13:00 (online) </li>\r\n</ul>\r\nFor online sessions, here is the <a href=\"https://epfl.zoom.us/j/63013630338\">Zoom link</a>.
