## Welcome | ||
|
||
I'm George Karypis, a Professor at the Department of Computer Science & Engineering | ||
at the University of Minnesota in the Twin Cities of Minneapolis and Saint Paul. | ||
|
||
## Research | ||
|
||
My research interests are concentrated in the areas of data mining, recommender | ||
systems, learning analytics, high-performance computing, and chemical informatics and | ||
from time-to-time, I look at various problems in the areas of health informatics, | ||
information retrieval, bioinformatics, and scientific computing. | ||
|
||
Within these areas, my research focuses in developing novel algorithms for solving | ||
important existing and/or emerging problems, and on developing practical software | ||
tools implementing some of these algorithms. The results from this research have been | ||
presented in various conferences and published in leading peer reviewed journals and | ||
highly selective conference proceedings. | ||
|
||
In my research I strive to develop algorithms that are practical (they can be easily | ||
implemented on commercially available platforms), efficient (require as little time | ||
as possible), effective (do a good job in solving the underlying problem), and | ||
scalable (remain efficient and effective as we increase the size of the problem | ||
and/or the number of processors). Quite often I consider my research as that of | ||
algorithm engineering. | ||
|
||
### Projects | ||
|
||
Over the years I have developed many algorithms for a variety of problems including | ||
dynamic load balancing of unstructured parallel computations, graph and circuit | ||
partitioning, protein remote homology prediction and fold recognition, protein | ||
structure prediction, recommender systems, data clustering, document classification | ||
and clustering, frequent pattern discovery in diverse datasets (transactions, | ||
sequences, graphs), parallel Cholesky factorization, and parallel preconditioners. | ||
|
||
### Software | ||
|
||
The research of my group research has resulted in the development of software | ||
libraries for serial and parallel graph partitioning (METIS and ParMETIS), hypergraph | ||
partitioning (hMETIS), for parallel Cholesky factorization (PSPASES), for | ||
collaborative filtering-based recommendation algorithms (SUGGEST), clustering high | ||
dimensional datasets (CLUTO), and finding frequent patterns in diverse datasets | ||
(PAFI). In addition, my group has developed two web-based servers for clustering gene | ||
expression data (gCLUTO) and for predicting the secondary structure of proteins | ||
(YASSPP). | ||
|
||
### Publications | ||
|
||
I have coauthored over one hundred journal and conference papers on these topics and | ||
a book titled "Introduction to Parallel Computing" (Publ. Addison Wesley, 2003, 2nd | ||
edition). | ||
|
||
|
||
## Education, Mentoring, and Advising | ||
|
||
I take great joy in teaching, advising, and mentoring undergraduate and graduate | ||
students and I consider it to be one of the perks of my job. | ||
|
||
My greatest pleasure and ultimate job satisfaction comes at those points during a | ||
course at which my students transition from simply listening and reading the material | ||
to actually understanding them, grasping them, internalizing them, and seeing how | ||
they fit within the general computer science discipline and how they are applied to | ||
solve real problems in real applications. | ||
|
||
### Teaching | ||
|
||
My regular teaching responsibilities include the introductory course on algorithms | ||
and data structures (CSci 4041), a course on parallel computing (CSci 5451), a course | ||
on data mining (CSci 5523), and a course describing various computational techniques | ||
used in bioinformatics (CSci 5481). | ||
|
||
|
||
### Advising | ||
|
||
Over the years I had the opportunity to advise and mentor many Ph.D. and M.S. | ||
students. I find this to be a very rewarding experience and I have learned (and still | ||
learning) a lot from all of my former and current students. | ||
|
||
I believe that effective advisor-advisee relationships must be built on mutual trust, | ||
commitment, and benefit, and be designed to advance the advisees education and | ||
provide them with a solid foundation upon which to build their future career. | ||
|
||
Pursing an advanced graduate degree and contacting research to advance the | ||
state-of-the-art is not an easy task. Its outcome is never guaranteed, there are | ||
always unforeseen complications, and not every idea works out! It requires | ||
commitment, dedication, hard work, and the ability to know when to continue pursuing | ||
a good idea even when the initial results are not very encouraging and when to stop | ||
pursing a bad idea and start over again. I do not expect my students to be expert | ||
researchers when joining my group, but I expect them to be bright, dedicated, | ||
motivated, and willing to work as hard as I do. | ||
