Past Lab Members

Postdoc Researchers

Sujoy Ghosh - Sujoy completed his B.Sc. and M.Sc. degrees from the University of Calcutta in India, in 2006 and 2008. Then he completed his M.S. and Ph.D. in Physics from Southern Illinois University in 2011 and 2016. He joined the flexible electronics group at UNH in January of 2017 and worked jointly in the Hollen, Song, and Tsavalas labs. His postdoctoral position was supported by the UNH Center for Advanced Materials and Manufacturing Innovations (CAMMI). He is now working as a staff scientist at Los Alamos National Laboratory.

Jason Moscatello- Jason received his B.S. in Physics with a minor in Women & Gender Studies from The College of New Jersey in 2000, an M.S in Physics from The College of William & Mary in 2002, and his Ph.D. in Engineering Physics from Michigan Technological University in 2010.  His dissertation research focused on growing carbon nanotubes and developing the methods required to integrate them into molecular electronic and sensing devices.  Jason's post-doctoral work was at Mount Holyoke College, where he developed a new method for measuring trap states in quantum dot and organic field effect transistors. At UNH, Jason developed MATLAB solutions for lab needs, and expanded the group's atomic force microscopy capability. He is now a Senior Algorithm Engineer and Physicist at Textron Systems, MA. 

Graduate Students

Ben St. Laurent - Ben received a B.S. in physics from the University of North Carolina Wilmington in 2014 and an M.S. in engineering physics with a Professional Science Master's concentration in nanoscience for advanced materials from Appalachian State University in 2016.  He is currently pursuing a Ph.D. in physics at the University of New Hampshire where he joined Hollen Lab during the summer of 2017.

Steven Arias - Steven received a B.S. in Physics from the University of New Hampshire in May 2016. He joined the UNH Ph.D. program in the fall of 2016 and began work with the Hollen Lab in the spring of 2017. He is a recipient of the DOE SCGSR fellowship in partnership with the Center for Functional Nanomaterials at Brookhaven National Laboratory and will be completing his fellowship year in 2021-2022. 

Jake Riffle - Jake received his B.A. in physics from Clemson University in 2014. He then joined UNH's Ph.D. program for experimental condensed matter physics and has been working under Dr. Shawna Hollen since the Fall of 2015. He defended his dissertation, titled "The Effects of Disorder in van der Waal Materials," in February of 2022 and graduated May of 2022.
He enjoys playing classical guitar and metalworking as a hobby in his spare time.
