Sue is an associate professor in the Chemical Engineering Department at The University of Massachusetts Amherst. She also holds a position as the director of the UMass Amherst Institute for Cellular Engineering (ICE). She obtained her B.S. in Chemical Engineering from Worcester Polytechnic Institute in 1992 and Ph.D. in Chemical Engineering from Cornell University in 1998.
Whitney Stoppel completed her B.S. in Chemical Engineering with minors in Mathematics and Cell & Molecular Biology at Tulane University in 2008. Following an REU program in Cellular Engineering at UMass in 2007, Whitney chose to attend graduate school at UMass, continuing to work in the Roberts lab. She joined the Roberts lab in the fall of 2008, and is working on enhancing the growth and functionality of mammalian cells in 3-D constructs by tailoring mechanical and physiological properties within the device through a collaboration with Surita Bhatia, Kim Tremblay, and Al Crosby.

Sarah Wilson completed her B.S. in Chemical Engineering at Rowan University in the spring of 2009. She decided to attend graduate school at UMass to conduct research in cellular engineering and joined the Roberts group in the fall of 2009. Sarah's focus is on characterizing novel genes involved in paclitaxel production with an overall goal to enhance the accumulation and production of paclitaxel in Taxus cell cultures through agrobacterium-mediated transformation. She is completing this work in collaboration with Joyce Van Eck at the Boyce Thompson Institute for Plant Research in Ithaca, New York.

Lisa Leone completed her B.S. in Chemical Engineering at Drexel University in Philadelphia. During the course of her undergraduate education she participated in internship programs at ConocoPhillips, Dupont and Genencor, the last of which sparked an interest in biotechnology. She joined the Roberts group in the fall of 2010 to optimize plant cell growth in bioreactors through a combination of mathematical modelling and experimental techniques in collaboration with Mike Henson.

Research Fellows
Vanessa Bartolo completed her B.S. in Biology with a minor in Chemistry at Elms College in 2014. Shortly after, she joined the Roberts lab as a technician working with the extensive live plant tissue culture collection donated by Monsanto. Here, she maintains the cultures and is currently working on cold storage experiments with the goal of transitioning the cells to lower temperatures where metabolic processes slow in order to reduce labor and cost for the long-term maintenance of the large collection. She plans on starting her PhD in Microbiology in the fall of 2016.
Kelsey Mantoni joined the Roberts Lab in the fall of 2011 as a sophomore honor chemical engineering student to begin work on her Capstone honors thesis. Kelsey will be working with Whitney in the field of biomaterials and tissue engineering.
Bronwyn Finney joined the Roberts Lab in the fall of 2013 as a sophomore honor chemical engineering student to begin work on her Capstone honors thesis. Bronwyn will be working on the metabolic engineering of Taxus suspension cultures.
