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.

Lanesborough Officials Review Schools' Budgets

LANESBOROUGH, Mass. — Town officials Monday appeared generally receptive to the fiscal year 2027 spending plans for the two public school districts that serve the town.
 
Superintendents from the Northern Berkshire Vocational Regional School District (McCann Technical School) and Mount Greylock Regional School District presented their respective FY27 budgets to a joint meeting of the town's Finance Committee and Select Board.
 
Both districts are sending significantly higher assessments for approval at Lanesborough's annual town meeting in June.
 
McCann Tech, which constituted a $317,109 expenditure for the town in the current fiscal year, is seeking $463,978 for the fiscal year that begins on July 1 even though the school's operating budget is up just 3.2 percent year to year.
 
The 46 percent increase in Lanesborough's share of McCann Tech's budget is is due to two factors: a rise in enrollment of town residents at the vocational school from 20 in 2025 to 29 in this school year and a capital assessment for the first round of payments — for interest only — for a roof and window replacement project on the North Adams campus.
 
The Mount Greylock assessment, a much larger component of Lanesborough's property tax bill, is up 10.99 percent from FY26 to FY27, from $6.8 million to $7.6 million.
 
Mount Greylock Superintendent Joseph Bergeron gave a budget presentation similar to one he has delivered twice to the district's School Committee and again last month to the Williamstown Finance Committee, explaining that while the FY27 budget maintains level services to students with a net reduction of three positions, a series of factors are driving much larger assessments to Mount Greylock's two member towns.
