I am originally from Houghton, MI. I completed my B.S. degree in the Biosystems Engineering department at MSU, during which time I completed a semester study abroad at the University of León in León, Spain. I also had internships at Nestlé USA (industrial engineering) and Kellogg Company (food chemistry/material properties) prior to starting graduate school. For graduate school, I went to California, where I completed my M.S. and Ph.D. in Biological Systems Engineering at the University of California, Davis working in the area of food breakdown during digestion, both in vitro and in vivo. During my PhD, I was a visiting scholar at the Riddet Institute at Massey University (Palmerston North, New Zealand) 3 times, for about a year in total. After finishing my PhD, I was a Postdoctoral Scholar at UC Davis for a year, working on digestibility and breakdown of almond proteins in vivo and mechanisms of food breakdown in vitro before coming back to MSU!
