happy to answer any questions you may have!

My name is Suchan, and as a former
participant & medallist in the IMO a
decade ago (!), I'm happy to be back here
representing QuantCo. It's hard to believe
how quickly time passes, and I feel quite
old now! I completed my bachelor's andmaster's degrees in computer science and mathematics at MIT andam passionate about combinatorics, probability, and statistics. At
QuantCo, my work involves building machine learning models,
optimizing solutions, and programming high-performance code.
I am Alejandro, and I completed mybachelor's and master's degree inelectrical engineering at ETH Zurich(CH), where I focused on Machine
Learning

inthemedicalandautomotive fields. At QuantCo, I team
up

with

excellentengineers,

economists, and statisticians. Together, we help clients get the mostout of their data: leveraging our Machine Learning and programming
expertise to optimize data-based processes by developing robustand efficient solutions.

I am Carolin, and I have a background inquantitative

economics(aka

econometrics). I studied in Germany,
Canada, Sweden, and the US, where I
spent a year at Stanford researchingcausal inference and machine learning.
I was intrigued by recruiting at QuantCoand am now responsible for our global data science recruiting
covering the US, UK, and Europe. I also travel to various
competitions representing QuantCo, such as the IMO, EGMO,

Tea Ceremony with URASENKE lecturer! (July 9th)
Michael Hardy Sōgetsu (Urasenke Chadō Instructor)

Chadō,

commonlyreferred

to

as

“Tea

Ceremony” in English, is actually a spiritual andaesthetic discipline for refinement of the self —known as a ‘way,’ or dō, in Japanese. Throughthe Way of Tea, students seek the principles of Harmony,
Respect, Purity, and Tranquility. Within the preparation ofmatcha tea, there lies over four hundred years of knowledge,
wisdom, history, and culture. Chadō is concerned with simple
though meaningful everyday-life activities, yet to master Chadō
requires great cultivation. The enduring allure of the Way of Tea
since its perfection by Sen Rikyu in the 1500s is proof of the deep
meaning that this “Art of Living” holds for all people.

Tsutsumi Junko’s FUROSHIKI (July 10th)

Junko Tsutsumi tells you the beauty ofFuroshiki, how to fold, how to wrap up
things, as well as introducing themathematical patterns (tessellations).

Tessellation Design Association: Tessellation Puzzles!
& Math x Art Works (July 9th/11th)
How many triangles have you ever used, at most, totile/tessellate on a two-dimensional plane? Let’s
play tessellating triangle pieces not to solve given
problems but to pursue open-ended inquiries you just come up
with in the play. In the booth, a bunch of triangular pieces called
T3 Puzzle is available for you to create artwork, puzzles, andeven abstract strategy games.

Math x Origami : some art works to be provided(July 9th-11th)

Tachi Tomohiro Prof. at University of Tokyo

NTT Institute for Fundamental Mathematics was established asa research center for mathematics with the objective of becoming
one of the best research institutions of the world.
It is a remarkable fact that truly innovative mathematics that leadto completely new applications are often created out of the pure
curiosity of mathematicians. This shows that unpredictable value
is hidden precisely in explorations based on intellectual curiosity.
Curiosity is an invisible, but great ability of mankind to make new
discoveries and to develop new technologies. We, NTT Institutefor Fundamental Mathematics, will lead the exploration of thefrontiers of human knowledge as a world-class research center
for mathematics that finds routes between different fields anduncovers unknown truths, with intellectual curiosity as ourcompass and sail.
At our institute, we are waiting for your visit with the following
