Williams Professor Wins Grants to Study Evolutionary Genetics

Print Story | Email Story

WILLIAMSTOWN, Mass. — Two grants from the National Science Foundation (NSF) will support ongoing research by Luana Maroja, associate professor of biology at Williams College, into evolutionary genetics. The grants, totaling $137,315, were recently approved by the NSF.

The grants will support two projects Maroja is working on related to speciation and genetics. The first grant, for $91,173, will support collaborative research Maroja and her students are undertaking with Cornell University on the importance of sex chromosomes in speciation, specifically looking at whether genes that do not transfer genetic information from one species to another during hybridization are concentrated on the X chromosome. The project will provide important insights into the genomic architecture of speciation, the role of the X chromosome in reproductive isolation and divergent adaptation, and will contribute to ongoing debates about how differentiation accumulates in genomes over time.  

As part of the project, Maroja and her students will develop evolution workshops aimed to help educate middle and high school students.


The second grant of $46,142 will support a project in collaboration with Union College to understand processes that cause speciation. The project will test if chromosomal rearrangements (CRs) are involved in speciation using three distinct races of fruit flies. Maroja and her students will genetically map speciation phenotypes, male courtship song and female mating preferences for male song between two pairs of fruit fly races to determine certain traits are shared across the species. The project also will test whether CRs act to reduce gene exchange between nascent species by comparing patterns of genomic divergence inside CRs.

As part of this project, Maroja will develop evolution lab workshops aimed to help educate middle and high school students in Williamstown. She also will continue to develop workshops and labs for underserved girls and minorities in a partnership with the Flying Cloud Institute.

Maroja has taught at Williams since 2010. She has a bachelor's and master's degree from the Universidade Federal do Rio de Janeiro, and in 2008 she received a Ph.D. from Cornell.

Williamstown Board Opts to Negotiate with College on Water St. Lot

By Stephen DravisiBerkshires Staff

Newly elected board member Nate Budington, far left, participates in his first in-person meeting along with, from left, Matt Neely, Stephanie Boyd, Peter Beck, Shana Dixon and Town Manager Robert Menicocci.
WILLIAMSTOWN, Mass. — The Select Board on Monday decided to enter into negotiations with Williams College on the sale of the vacant town-owned lot at 59 Water St.
 
But the board members made it clear that the college's proposal to acquire the lot is a starting point, not a final deal that the elected officials would accept.
 
"For the sake of continued conversation, I'm in favor of [awarding Williams the site], but if this process wasn't continued with the opportunity for further negotiation, I wouldn't vote to continue this," Peter Beck said. "I think that next step is necessary for us to get to a yes on this."
 
"I think there's wide agreement on that," Matthew Neely said just before the 5-0 vote to enter talks with the college.
 
Williams was the sole respondent to a town-issued request for proposals to develop the former town garage site, currently a dirt lot.
 
The college's stated intent is to build a new Facilities office and create up to 170 parking spaces at 59 Water Street. That use will allow the college to redevelop the current Facilities building site and parking lot as part of a reconception of the school's indoor athletic and recreation facilities.
 
Under the terms of the RFP, the college's proposal was subjected to review by an ad hoc advisory committee to the town manager, who brought the question to the Select Board. That board will have the final say on any purchase and sales agreement.
