Dr. Lenore J. Cowen is a Professor in the Computer Science Department at Tufts University. She also has a courtesy appointment in the Tufts Mathematics Department. She received a BA in Mathematics from Yale and a Ph.D. in Mathematics from MIT. After finishing her Ph.D. in 1993, she was an NSF Postdoctoral Fellow and then joined the faculty of the Mathematical Sciences department (now renamed the Applied Mathematics and Statistics department) at Johns Hopkins University where she was promoted to the rank of Associate Professor in 2000. Lured by the Boston area, and the prospect of making an impact in a growing young department, she joined Tufts in September, 2001. Dr. Cowen has been named an ONR Young Investigator and a fellow of the Radcliffe Institute for Advanced Study. Her research interests span three areas: Discrete Mathematics (since high school), Algorithms (since 1991 in graduate school) and Computational Molecular Biology (since 2000). She is on the editorial board of SIAM Review.

Spring 2013, I am teaching Discrete Mathematics which I also taught in Fall 2008, Fall 2009, Spring 2010, and Spring 2012 and Fall 2012 .
Spring 2013 I am also teaching an advanced graduate seminar in Computational Biology, focused on PPI networks, and protein structure alignment.
Fall 2011, I taught Comp 167-- Computational Biology--
Spring 2011, I taught Advanced Algorithms which I last taught in Spring 2009.
Fall 2010, I taught Protein Bioinformatics Topics
Please note that the course links below point to the course web page for the *current* semester at Tufts, i.e. if it's a previous year, and I wasn't the last to teach it, you are going to be looking at the homepage for someone else's version of the class.
Spring 2008 I taught Algorithms.
Fall 2007 I taught one of my favorite courses: Graph Theory.
In Fall 2006, I taught Algorithms and an advanced topics seminar in Computational Biology.
In Spring 2006 I taught an introductory course in Cryptography
In Fall 2005 I taught Combinatorial Optimization
In Fall 2004 I taught Computational Biology (I also co-taught this class in Fall of 2002. )
Spring 2004 and Spring 2002 I taught an Advanced Algorithms class. Here's a little blurb.
Spring 2003 and Spring 2005 I taught and co-taught Theory of Computing
Fall 2002 I taught: Cryptography and Security and
Fall 2001 I taught COMP 15: Data Structures in C++.
Here are the classnotes for two of the graduate courses I taught at Hopkins: Approximation Algorithms and The Probabilistic Method.
I would say that my research interests are
probably far too broad for my
own good. I have inherited my advisor's love of good
problems, wherever they be found.
Exploiting locality and approximate distance have been persistent themes,
even across catagories, for example they have been used in our approach both
to routing and to classification and clustering problems. Now I am finding that my work on networks and graph algorithms may have some interesting synergies with computational biology and functional genomics. Research interests include:
My research in computational structural bioinformatics is funded by NIH grant 1R01GM080330-01A1 . Previous recent grants from NSF (grant CCR0208629) funded work on approximate routing, and portions of my computational biology research were previously funded by an NSF Large ITR grant with me as the Tufts PI and Simon Kasif of BU as the main PI.
My Ph.D. advisor was Daniel J. Kleitman ; my Ph.D. students to date were Christine Cheng (JHU/1999), 1/2 Christopher Wagner (JHU/1999), Adam Cannon (JHU/2000), Arthur Brady (Tufts/2008), Anoop Kumar (Tufts/2010) and Noah Daniels, (Tufts/2013). My current Ph.D. students are Mengfei Cao , Andrew Gallant and Hao Zhang.

For prospective graduate students: Tufts Computer Science admits to the department as a whole, not to an individual faculty member's research group. However, I am always interested in strong students who wish to work in computational biology. If you are interested in my research group, please say so in your application, so I will be sure to get to see it.
Graduated Ph.D. students:
High School Math Camps
The American Mathematics Society is now giving out grants to high school math camps!! They are currently raising endowment to support it, they are having real mathematicians judging the programs, they are charging 0 overhead to administer the program, and basically, I can't think of a better "bang" for your buck than supporting this, so check out their application process and give them money!!
As part of their effort, they are also (orthogonal to this) providing a central website where you can read about all the math camps (whether they applied for an AMS grant or not) -- so if you know a bright high school student, point them at this Information about High School Math Camps Site (I myself an alum of the Hampshire College Summer Studies in Math program, and I recommend it very highly!!)
Here's a Page I wrote about recommended places to pursue a graduate CS degree in Computational Biology (with suggested faculty advisors).
