Dear All,
You are most cordially invited to the ICTP 2025 Salam
Distinguished Lecture series by Prof. Aleksandra Walczak, École
normale supérieure, Paris
, on "Prediction in immune repertoires:
learning rules in a self-organised mess".
The lectures will take place (in presence) in the
Budinich Lecture Hall, Leonardo building, TODAY, Monday 27
January, at 11:00 and 14:00 hrs, and TOMORROW, Tuesday 28
January at 11:00 hrs.
Aleksandra
Walczak received her PhD in physics at the University
of California, San Diego, working on models of stochastic
gene expression. After a graduate fellowship at KITP, she
was a Princeton Center for Theoretical Science Fellow,
focusing on applying information theory to signal
processing. Currently she is a CNRS research director at the
Ecole Normale Superieure in Paris, interested in collective
behaviour, fly development and statistical descriptions of
the immune system. She was awarded the “Grand Prix Jacques
Herbrand de l’Académie des sciences" in 2014, the bronze
medal of CNRS in 2015, the American Physical Society
Fellowship, the Prix Jean Ricard of the French Physics
Society in 2021 and the silver medal of CNRS in 2024.
The Salam Distinguished Lecture Series is an annual
presentation of talks by renowned, active scientists. The
aim is to showcase important research developments as well
as provide a visionary forward view. The lecture series is
generously supported by the Kuwait Foundation for the
Advancement of Sciences (KFAS). The overarching title of the
three talks will be: "Prediction in immune
repertoires: learning rules in a self-organised mess"
Abstract:
Immune repertoires provide a unique fingerprint
reflecting the immune history of individuals, with potential
applications in precision medicine. Can this information be
used to identify a person uniquely? If it really is a
personalised medical record, can it inform us about the
outcomes of a COVID-19 infection? I will show how even a
system as complicated as the immune system has reproducible
outcomes. Yet predicting the future state of a complex
environment requires weighing the trust in new observations
against prior experiences. In this light, I will present a
view of the adaptive immune system as a dynamic Bayesian
machinery that updates its memory repertoire by balancing
evidence from new pathogen encounters against past
experience of infection to predict and prepare for future
threats. I will then attempt to connect data to phenotypic
models of evolution and show how the evolution of pathogens
is constrained by selection pressures coming from immune
systems. Together, I will present examples of how
statistical analysis described immune repertoires on
different scales.
There will be 3 lectures with the following titles:
Lecture 1: How personalised is your immune
repertoire?
Monday, 27 January 2025 starting at 11:00 hrs
Lecture 2: Optimal immune systems
Monday, 27 January 2025 starting at 14:00 hrs
Light refreshments will be served after the talk.
All are welcome to attend
Lecture 3: Viral—immune co-evolution
Tuesday, 28 January 2025 starting at 11:00 hrs
The lectures will also be livestreamed from the ICTP website
Looking
forward to your participation.
With best regards,
Erica Sarnataro, Quantitative Life Sciences section
