Vicky Li '14 and Francine Camacho '14, Bioinformatics majors, explored the metagenome of the guts of pill bugs (Porcellio Scaber) found in Norton and Cape Cod, MA.
- 2013Chris DeMolles '13 refactored his suite of Python modules to segment and count L-mers (L = 4-12) and the number of Inverted Repeats (IRs) as stock for machine learning algorithms to identify (potentially) new small RNAs.
- 2012Mengyang Li '14 and Chris DeMolles '13 started a new project for finding small RNAs. In the Fall, Mengyang, a Bioinformatics major, gave a series of lectures to the group on microbial RNAs. Chris prototyped SVM (Support Vector Machine) software to classify sequences of DNA as [RNA vs. non-coding, non-RNA]. Chris' software includes scripts to automatically check for new entries and then "scrape" needed files from NCBI's human microbiome project.Donald Bass '12 completed an honors thesis in computer science under Mike Kahn (Statistics) and LeBlanc on cluster validation techniques. As of the Fall 2012, Donald is at Northeastern University studying for his PhD in Computer Science.Kelsey Hichens '13 and Emily Baldwin '14 enrolled in a semester of research (COMP 499 -- Genomics Research) with LeBlanc and Dyer.
The research experience entitled "Detecting Horizontal Transfer in Microbial Genomes," led to the simHT software for simulating horizontal transfer between chunks for various microbes.
The two presented their results and software at CCSCNE 2012 in April.
- 2011Emily Baldwin '10 walked into LeBlanc's office as a first year student (before the semester started) and said, "I want to work with you in genomics." Emily, now a double computer science and mathematics major, plowed through our Perl book.
Donald Bass '12 upgraded the pipeline to help ensure that all the scripts used were both documented and cross platform, as well as rewriting several algorithms to ensure more accurate results, fixing severe bugs in two scripts that search the pubMed database and generate random genomes, and finally wrote a script to generate abstract chromosomes.
Nicholas Faulconer '12 spent the first week familiarizing himself with the “old” scripts, implemented by Neil Kathok '10. He fixed/adjusted/updated Scripts 1 and 4, and Seed.pl. In order for seed.pl to run and be updated he learned how to run a MySQL server.
Matthew Brousseau '11 revised Perl scripts to become cross platform while updating documentation in the scripts and pods as well as moving the Genomics site over to WordPress to look all nicey-nice.
Brandon Waltz '11 revised and updated documentation on all the experiment scripts as well as incorporated this website into the overall structure of the Wheaton web using WordPress.
Neil Kathok '10 wrote Perl scripts to test all the examples in our book and ported each example to the book's companion website. Neil has building a new database of microbial genomes and associated suite of scripts to automatically seed the database when new microbial genomes become available at NCBI.
- 2009Matt Brown '10 joined our weekly journal clubs in 2007 and 2008. He led SQL tutorials for the group as we began a new database design.
Through out the fall of 2007 and spring of 2008, the Genomics Group consisted of students Neil Kathok '10, Evan Ferri '08, and Matt Brown '10. Neil, Evan, and Matt worked with Professors Dyer, Kahn, and LeBlanc to update the group's microbial database and to design experiments that use genomic signature to investigate relationships between microbial plasmids and pathogenicity.
Christina Nelson '11 (right) presented some of our ongoing work on horizontal transfer to the President's Commission during the Fall semester. Her poster was entitled: 'Words and Rules in Horizontal Transfer'. Neil Kathok '10 finished a new database of 700+ microbial bugs and their associated metadata.
Evan Ferri '08 , a biology major, was quickly recruited to join our group after finishing our Perl DNA course. Evan kept the software types honest as we searched for genomic signatures between plasmids and their hosts durring 2007 and early 2008. Evan plans to go on to medical school.
While on year-long sabatticals, Betsey and Mark joined colleague Mike Kahn (Statistics) in a series of experiments to classify 200+ bacteria and archaea genomes by temperature regime (hyperthermophile, thermophile, or mesophile). Mike introduced the group to the statistical programming language "R" where Mark and Mike developed models using CART (Classification and Regression Trees). The work led to a publication in the journal Archaea 2:159-167, 2007.
Neil Kathok '10 (right) joined the Genomics Group in the Spring of 2007 to help test all of the Perl routines to appear in our new book, Perl for Exploring DNA. Neil also created a website which will appear on the book's Oxford University Press companion website to allow users of the text to download all of the Perl examples.
Robbie Grossman '07 was a computer science major who lent considerable expertise in database design and Perl scripts to automatically seed our a database of microbial genomes.
Sarah Milewski '07 was a computer science major. Sarah implemented routines to seed our new microbial database.
Mark and Betsey made inroads with reaching the national community of computer science professors as they presented workshops at CCSC-Eastern (Iona College, NY) and SIGCSE (Houston, TX). With "pre-doc" Greg Williams '02 as a consultant, Mark and Betsey shipped their manuscript for their new book, 'Perl for Exploring Biological Sequences' (Oxford University Press, due out in early 2007). The group received additional funding and a one-year extension on their NSF grant (NSF DUE # 0340761), to help finish their book.
Under the leadership of Wheaton Biology Professor Shawn McCafferty, Mark and Nguni Phakela '06 developed some software to help Shawn with his research in phylogenetic analyses. In particular, Nguni and Mark implemented routines to compute patristic distances of a variable number of organisms.
Sarah Milewski '07 and Robbie Grossman '07 designed and prototyped a database to store the entire chromosomal and plasmid DNA for over 300 prokaryotic genomes. Greg Williams '02 helped implement a final version. The database is a huge move forward for the group as it holds metadata on the each organism (e.g., salinity, mobility, temperature range, etc), thus facilitating the range of questions to pose of microbial genomes.
Nguni Phakela '06, was Wheaton's first double major in computer science and biochemistry. Nguni prototyped some of first experimental software in phylogenetics under the guidance of Biology Professor Shawn McCafferty.
Steve Benz finished his senior year helping Betsey upgrade the favGene tool. Betsey presented some of her work at ASM. Mark taught and did research at the University of Wollongong (UoW), Australia for the year. He presented the group's work on favGene at the International Conference on Bioinformatics in Auckland, New Zealand. Mark worked with Paul White (UoW) '06 on a set of routines to automate experimental runs that test authorship attribution techniques, typically used on English texts, in the context of identifying the kingdom, genus, and species of a given sequence of DNA.
Stephen Benz '05 was a computer science major and biochemistry minor and is now a Ph.D. student in Bioinformatics (starting in Fall 2007). Steve was our lead programmer for two years in 2004 and 2005. Steve worked from the west coast during the summer of 2002 completing the redesign of our GUI for the Motif Lexicon v2.0. Steve was funded for the 2002-2003 academic year and worked on the design and implementation of regular expressions and software to search for putative zinc-finger binding sites.
Chris Wilbur '05 biology major. Chris put together a DNA helix model, a beautiful addition to our lab.
In a year-long project, Steve Benz '05, Robby Grossman '07, and Nguni Phakela '06 worked on version 2.0 of the "favorite gene" project. favGene is an application that stores genomes in a MySQL database on the backend to facilitate a user (via Perl scripts on the frontend) in selecting and assembling the DNA sequences in the upstream, downstream, and/or genic regions of their "favorite" set of genes. Additional Perl scripts allow the user to either take home their sequences or search just those regions for various motifs using regular expressions. Steve and Robby presented their work at the northeast regional conference on computer science education (CCSCNE 2004) at Union College in April 2004. As part of a new NSF grant (NSF DUE # 0340761), Robby and Steve will work during the summer of 2004 on favGene.
Patrick Sagui '04 computer science major. Patrick is a jack-of-all-boxes. Pat ported our Perl and C++ CGIs to a new Linux box over the summer of 2002 and helped with the upgrade of the Motif Lexicon to v2.0.
Pete Cahalan '04, scripted in C++ and Perl during the summer of 2003 as the Motif Lexicon moved to v3.0. Pete and Brian left scripts and directions for handling new organisms that are added to the Motif Lexicon.
Brian Donorfio '04, moved the Motif Lexicon to v3.0 during the summer of 2003; v3.0 handles multiple organisms. Pete and Brian worked during the summer of 2003 on the Motif Lexicon. They shipped v3.0 of the lexicon so that it includes the functionality of handling multiple organisms.
Jonah Cool '04 Jonah worked with Steve Benz on the favGene application. Jonah researched the literature for Zinc Finger transcription factors and their associated DNA binding sites. Jonah is working on his Ph.D. in Biology.

Spring 2003 Images
During January break Nick Doolittle '03 started a new module to find all repeats of any length with unlimited loop size. Missy Kimball '02 integrated a new module to give the statistical likelihood of a requested motif. This module was the result of earlier work by Andrea Chritoforou '01. Greg Williams '02 wrote a very cool "Etymology" module which searches PubMed for all published abstracts for one's requested motif. In the spring Greg Williams '02 enrolled in COMP 499 - Genomics Research - and implemented a suite of filters for motifs in the regulatory regions of some of the genes involved in making the flagella in bacteria. His version of the "favorite gene project" is due in the Fall of 2002.
Martin Baron '03 and Patrick Sagui '04 (above) were Mars Fellows for the summer. Martin and Pat moved the motif lexicon to version 2.0, implementing a number of enhancements to the GUI and statistics module. Martin added a new "relateds" module for the lexicon while Pat ported our CGIs to a new Linux box. In the August 19, 2002, v17 issue of The Scientist, Dyer, B. and LeBlanc, M. published free user-friendly genomics software.
Missy Kimball '02 dual mathematics and computer science major. A jack of all trades, you could usually find her proving abstract theorems, working on programs in C, or belting out tunes with the Whims, the acappella group. Missy prototyped the initial motif lexicon in Perl and C and added a new statistical module in January 2002. Missy is a graduate student at UNH.
