Basic info
I am at ICSI and the Department of Statistics at UC Berkeley, and
I am also in the
RISELab
(in the past AMPLab)
in the Department of Computer Science.
You can reach me via electronic mail:
mmahoney
is the username, and

follows the at symbol.
(Of course, my gmail address is still valid.)
Also, some other (somewhat outdated) information can be found at
my old web page
at Stanford and
my older web page
at Yale.

Students, postdocs, etc.
Most of my work focuses on the theory and practice of what is now called big data, although I was doing it back when it was just massive, and prior to that when it was just large.
On the theory side, we develop algorithms and statistical methods for matrix, graph, regression, optimization, and related problems.
On the practice side, we provide implementations (e.g., on single machine, distributed data system, and supercomputer environments), and we also apply the methods to a range of problems in internet and social media analysis, social networks analysis, as well as genetics, mass spec imaging, astronomy, climate, and a range of other scientific applications.
I have been fortunate enough to work with a number of great students and postdocs over the years.

Research interests

Algorithmic and statistical aspects of modern largescale data analysis.

Randomized linear algebra and randomized numerical linear algebra.

Implicit regularization and implicit optimization
methods in scalable approximation algorithms.

Graph approximation algorithms and applications to large social and information networks.

Applications to DNA microarray, SNP, astronomical, medical imaging, and other scientific data.
A lot of my work has focused on
Randomized Linear Algebra, i.e., using random sampling and
random projection methods to solve very large matrixbased problems;
developing
geometric network analysis tools, i.e., using scalable approximation
algorithms with a geometric
or statistical flavor to analyze the structure and dynamics of large
informatics graphs;
developing approximate computation and regularization methods for large
informatics graphs;
applications to community detection, clustering, and information dynamics in
large social and information networks; and
applications to DNA single nucleotide polymorphism (SNP) data,
astronomical and medical imaging data,
and largescale statistical data analysis more generally.
In the past, I developed and analyzed algorithms for large matrix, graph,
and regression problems, and I applied these and related tools to the
statistical data analysis of extremely large scientific and Internet data
sets.
For example, I worked on
largescale web analytics, machine learning, and query log analysis;
applications of graph partitioning algorithms to clustering and
community identification; and
applications of randomized matrix algorithms to hyperspectral medical image
data, DNA microarray data, and DNA SNP data.
In the more distant past, I have also worked on developing and analyzing
Monte Carlo algorithms for performing useful computations on extremely
large matrices,
e.g., the additiveerror and relativeerror CUR matrix decompositions.
Past research has also included work in computational statistical mechanics
on the
development and analysis of the
TIP5P
model of liquid water, as well as work in both computational and experimental
biophysics on proteins and proteinnucleic acid interactions.

MMDS Workshops
I run the MMDS meetings.
We started the
MMDS Workshops on
"Algorithms for Modern Massive Data Sets"
to address
algorithmic and statistical
challenges in modern largescale statistical data analysis.

MMDS 2016
took place on the campus of UC Berkeley on June 2124, 2016.
See the
main MMDS web page
for more information.

MMDS 2014
took place on the campus of UC Berkeley on June 1720, 2014.
See the
main MMDS web page
for more information.
Click
here for the entire
video collection.

MMDS 2012
took place on the campus of Stanford University on July 1013, 2012.
For pdfs and videos of the presentations, go to the main MMDS web
page; or click
here for the entire
video collection.

MMDS 2010
took place on the campus of Stanford University on June 1518, 2010.
MMDS 2010 addressed computation in largescale scientific and internet data
applications more generally.
See
the MMDS web page
for details, including articles and all the speaker overheads!

MMDS 2008
took place on June 2528, 2008.
MMDS 2008 grew out of our expectation for what
the algorithmic and statistical
foundations of
largescale
data analysis
should look like a generation from now.
Click
here
for an article that appeared in SIGKDD Explorations and
SIAM News about the meeting.

MMDS 2006
took place on June 2124, 2006.
MMDS 2006 was originally motivated by the complementary perspectives
brought by numerical linear algebra and theoretical computer science to
matrix algorithms in largescale data applications.
Click
here
for an article in SIAM News about the meeting.
These MMDS meetings generated intense interdisciplinary interest and were a
big success  so keep an eye out for future MMDSs!

My old web page
at Yale has additional (somewhat outdated) information;
and my less old web page
at Stanford has additional (somewhat less outdated) information;
but you should click on them (or Google search for them) if you are interested in
extremely large homes.
