Dean R. Tolan, a professor of biology at Boston University, is writing a letter of recommendation for Laura Serio. The letter states that Laura worked in Tolan's lab from May to October 2009, where she succeeded in producing chimeric constructs of aldolase A and C and studying their expression and purification. Tolan impressed that Laura is a highly motivated and talented experimentalist who acquired important lab skills. He would reappoint Laura to work with his group again and recommends her as a research fellow.
