Advisor: Prof. Ravi Janardan
Rahul Saladi got his Ph.D. from University of Minnesota. He
obtained his bachelor's degree and master's degree in computer science from IIIT-Hyderabad.
Rahul has been awarded the Computer Science Fellowship in Fall 2011 and the Doctoral Dissertation Fellowship (DDF) for the
2014-15. At the Fast Forward Preview Session at ACM SIGSPATIAL GIS 2012 he was awarded the first prize for his presentation. He has published his
work in top theoretical computer science venues (SODA, SoCG) and in top databases venues (PODS, IEEE TKDE).
Geometric algorithms and data structures, Approximation algorithms.
During my Ph.D. I worked on range-searching problems
which has been very well studied by the computational geometry
and the database community. In range-searching queries, the user
is not interested in the entire input geometric dataset, but only
in a small subset of it and requests an informative summary
of that small subset of the data. In many applications (such as
Google Maps, Yelp, housing/dating websites) the same dataset
is queried several times, in which case one would like to answer
the queries faster by preprocessing the dataset into a data-structure.
The goal is to organize the data into a data-structure which occupies
a small amount of space on the computer and yet responds to any user query in
real-time. Read my thesis, or/and
defense slides, or/and
research statement for details...
