Alexandr Andoni
Info about me:
I am a researcher in Computer Science, with interests broadly revolving
around big data algorithmics, in particular sublinear
algorithms and theoretical machine learning.
Some technical interests include highdimensional computational geometry, metric
embeddings, streaming, property testing, and theory of learning.
I graduated from MIT in
2009, under
the supervision of Prof. Piotr Indyk. My PhD thesis
is on the "Nearest Neighbor Search: the Old, the
New, and the Impossible"
[.pdf, .ps].
In 20092010, I was a postdoc at
the Center
for Computational
Intractability at Princeton, and a
visitor at
NYU
and IAS.
I was a researcher at Microsoft
Research Silicon Valley lab, from 2010 until its closure in 2014.

Foundations of Computer Science (MFCS), 2011, and
older version (pdf
format) at
the Workshop

Professional Service:
Program Committee of: SODA'15, FOCS'13, MASSIVE'12, APPROX'12,
ESAB'12 (experimental track), STOC'11, CPM'11, RANDOM'10.
Coorganizer
of the Bertinoro
Workshop on Sublinear Algorithms 2014 (together with Piotr
Indyk, Robert Krauthgamer, and Sofya Raskhodnikova).
Coorganizer
of the "Data Structures (in memory of Mihai Pătraşcu)"
workshop at FOCS'12
(together with Erik Demaine, Piotr Indyk, and Mikkel
Thorup).
Coorganizer
of the
workshop
on embeddings as part of
the Discrete
Analysis programme at the Isaac Newton Institute for
Mathematical Sciences, Cambridge, UK (together with Tim Austin
and Assaf Naor).
LSH:
I maintain a page on LocalitySensitive
Hashing (LSH). LSH is a practical algorithm for approximate nearest
neighbor problem (in high dimensions).
Other (i.e., random stuff):
ACM ICPC: I used to be one of the coaches for the MIT's team for ACM International Collegiate Programming
Contest.
AntiChess: Play my AntiChess
:) (a 6.170 class project, joint with Cristian Cadar and Tudor
Leu). Warning: the rendering might be suboptimal (different
browsers tend to diplay the board sligthly differently). If you
find 3min too little, you can change the time in the menus
('Options>Change player options').
A paranthesis that will hopefully
help search engines better index my
webpage. Alternative spellings of my
name are: Alexandru Andoni (in Romanian, my normal name, although not
the official one due to some hardtoexplain bureaucracy), Alexander
Andoni ("anglified" version), and Alex Andoni (simplified version :).
