The Spring 2022 Brains, Minds, and Machines (BMM) Seminar Series will be hosted in a hybrid format. Please see the information included below regarding attending the event either in-person or remotely via Zoom connection

Please note, MIT is requiring that all attendees, including MIT COVIDpass users, sign-in to the event prior to entering the auditorium.

Abstract: Human minds have produced laws to describe complex systems along with numerical methods and algorithms that harness the powers of modern supercomputers. Simulations and data processing have provided our generation with unprecedented physical insight. Despite progress in methods, software and hardware we realize that we will never be able to rely solely on this mode of inquiry to understand, predict and control complex systems. Artificial intelligence (AI) offers new modes of inquiry but questions remain on whether it replaces exiting modes of inquiry, complements them and how ? In this talk I will present algorithms formulated on a fusion of computational science and AI for the prediction and control of diverse physical systems. I will present the Remember and Forget Experience Replay (ReFer) algorithm for reinforcement learning, a multiscale approach to Learning the Effective Dynamics (LED) of complex systems and a fusion of scientific computing and multi-agent reinforcement learning (SciMARL) for developing closures for unresolved dynamics of complex systems. Examples will include benchmark problems from physics engines to high fidelity simulations of complex systems that range from molecular systems to fish schooling. I will discuss successes and failures and hope for a dialogue on how the integration of AI and Computational science may lead to new forms of Computational Intelligence.

Bio: Petros Koumoutsakos is Herbert S. Winokur, Jr. Professor of Engineering and Applied Sciences, Faculty Director of the Institute for Applied Computational Science (IACS) and Department Chair of Applied Mathematics at Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS). He studied Naval Architecture (Diploma-NTU of Athens, M.Eng.-U. of Michigan), Aeronautics and Applied Mathematics (PhD-Caltech) and has served as the Chair of Computational Science at ETH Zurich (1997-2020). Petros is elected Fellow of the American Society of Mechanical Engineers (ASME), the American Physical Society (APS), the Society of Industrial and Applied Mathematics (SIAM). He is recipient of the Advanced Investigator Award by the European Research Council and the ACM Gordon Bell prize in Supercomputing. He is elected International Member to the US National Academy of Engineering (NAE). His research interests are on the fundamentals and applications of computing and artificial intelligence to understand, predict and optimize fluid flows in engineering, nanotechnology, and medicine.

Guidance for attending in-person:

MIT attendees:
MIT attendees will need to be registered via the MIT COVIDpass system to have access to MIT Building 46.
Please visit URL https://covidpass.mit.edu/ for more information regarding MIT COVIDpass.

MIT Covid Pass users do not need to fill out a Tim Ticket, but still need to be scanned in upon event entry. (Tim Tickets are used only for non-MIT event attendees.)

On the day of the event, please make sure to complete your testing and attestation requirements. Please complete your attestation no earlier than 24 hours in advance of the event and no later than 30 minutes prior to the event.

Present the barcode on the back of your MIT ID card (removed from any encasing) or in your MIT Atlas mobile app.

Non-MIT attendees:

MIT is currently welcoming visitors to attend talks in person. All visitors to the MIT campus are required to follow MIT COVID19 protocols, see URL https://now.mit.edu/policies/campus-access-and-visitors/.  Specifically, visitors are required to wear a face-covering/mask while indoors and use the new MIT TIM Ticket system for accessing MIT buildings. Per MIT’s event policy, use of the Tim Tickets system is required for all indoor events; for information about this and other current MIT policies, visit MIT Now.

Please obtain your Tim Ticket no earlier than 24 hours in advance of the event and no later than 30 minutes prior to the event.

  1. Please follow the TIM Ticket link listed below.
  2. Click on “Visitor”
  3. Enter mobile number / cell phone number
  4. Enter pin code sent to your mobile device
  5.  Enter contact details
  6. Tim Ticket Registration acknowledgement, click on, “I’m ready! Let’s get started”
  7. Read acknowledgment form and accept MIT guidelines for campus access and agree to adhere to MIT rules/protocols.
  8. Attest you have been fully vaccinated against Covid-19 or have a religious belief or medical condition that prevents you from receiving the vaccine.
  9. Tap Tim Ticket, swipe down, and click on “Submit my daily attestation” Reminder: you must attest no earlier than 24 hours in advance of the event and no later than 30 minutes prior to the event
  10.  Fill out the daily attestation and tap submit when completed
  11. 1Confirm your attestation is correct
  12. You will be presented a QR code. This QR code is tied to your name and contact information that you can then use to scan for both building and event access

To access MIT Bldg. 46 with a TIM Ticket, please enter the building via the McGovern/Main Street entrance - 524 Main Street (on GPS). This entrance is equipped with a QR reader that can read the TIM Ticket. A map of the location of, and an image of, this entrance is available at URL: https://mcgovern.mit.edu/contact-us/

General TIM Ticket information:

Please read MIT’s Privacy Statement, which explains how MIT handles and uses the personal information we collect as part of MIT’s Tim Tickets application: https://covidapps.mit.edu/privacy

A visitor may use a Tim Ticket to access Bldg. 46 any time between 6 a.m. and 6 p.m., M-F.

Visitors must complete a health attestation no earlier than 24 hours in advance of their visit and no later than 30 minutes prior to the event

A Tim Ticket is a QR code that serves as a visitor pass. A Tim Ticket, named for MIT’s mascot, Tim the Beaver, is the equivalent of giving someone your key to unlock a building door, without actually giving up your keys.

This system allows MIT to collect basic information about visitors entering MIT buildings while providing MIT hosts a convenient way to invite visitors to safely access our campus.

Information collected by the TIM Ticket:

  • Name
  • Phone number
  • Email address
  • COVID-19 vaccination status (i.e., whether fully vaccinated or exempt)
  • Symptom status and wellness information for the day of visit

The Tim Tickets system can be accessed by invited guests through the MIT Tim Tickets mobile application (available for iOS 13+ or Android 7+) or on the web at visitors.mit.edu.

Visitors must acknowledge and agree to terms for campus access, confirm basic contact information, and submit a brief attestation about health and vaccination status. Visitors should complete these steps at least 30 minutes before scanning into an MIT building.
