Spring 2017 I am teaching Discrete Mathematics which I also taught in Fall 2008, Fall 2009, Spring 2010, Spring 2012, Fall 2012, Spring 2013, Spring 2016 and Fall 2016.

Fall 2016 I taught an experimental elective course which was an introduction to Computational Biology from the perspective of Big Data.

Spring 2015, I also taught Advanced Algorithms which I last taught in Spring 2011 and in Spring 2009.

Fall 2015 I am teaching Computation Theory

Spring 2013 I am also taught an advanced graduate seminar in Computational Biology, focused on PPI networks, and protein structure alignment.

Fall 2011, I taught Comp 167-- Computational Biology--

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.


What I work on

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 biology was funded by NIH grant 1R01GM080330-01A1 from 2008-2013. . 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 graduated Ph.D. students to date are 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), and Mengfei Cao (Tufts/2016) . Plus I co-advised Guangtao Ge's doctorate in 2009.

(My Erdos number is 2 (but so is everyone else's)).
