About
PISA brings together researchers working in probability theory and its applications. The 2027 edition is a three-day conference of invited research talks, held on January 13–15 at the San Joaquín Campus of the Pontificia Universidad Católica de Chile.
The following week, the Universidad de Chile hosts a Summer School in Probability, also in Santiago. Visitors can plan a single trip and take part in both events. See further information below.

Four classical models from probability, simulated live in your browser.
Move the sliders and tap the pictures.
Each edge of the grid is open, independently, with probability p. Clusters joining the left and right sides are drawn in gold. On the square lattice the critical value is pc = 1/2 (Kesten, 1980). Hover or tap a cluster to measure it.
Every individual has a Poisson(m) number of children; rings are generations. Gold lines are the lineages still alive in the last generation. Extinction is certain when m ≤ 1, while for m > 1 the family survives forever with positive probability.
Each cell carries an Exp(1) weight, and the passage time to a cell is the heaviest up-right path from the corner. The region reached by time t approaches the dashed curve (√x + √y)² = t (Rost, 1981), and the passage time to (n, n) has Tracy–Widom fluctuations of order n1/3 (Johansson, 2000). Dark lines are geodesics; hover or tap to draw your own.

Venue & travel
Pontificia Universidad Católica de Chile
Av. Vicuña Mackenna 4860, Macul, Santiago
Metro Line 5 stops at San Joaquín station, across the avenue from the campus. The lecture room will be announced with the program.
Line 5 connects with Line 1 at Baquedano, with Line 6 at Ñuble and with Line 4 at Vicente Valdés.
Open in Google Maps ↗Santiago’s international airport (SCL) is on the western edge of the city. Official taxis and shared shuttles such as Transvip have counters in the arrivals hall. Airport buses (Centropuerto, Turbus) run to central Santiago and connect with the Metro.
Metro and buses are paid with the Bip! card, sold at Metro stations. Ride-hailing apps are also widely used in Santiago.
January is midsummer in Santiago: hot, dry days and cool evenings. Bring sunscreen and a hat.
The currency is the Chilean peso (CLP). Cards are accepted almost everywhere and ATMs are easy to find. Exchange offices (casas de cambio) usually give better rates than banks.
The week after
The Summer School in Probabilities and Stochastic Processes, organized by the CMM at the Universidad de Chile, takes place the week after PISA, also in Santiago. Plan your visit to take part in both events.
